Today, I will introduce a national invention authorized patent-a walk-in high and low temperature rapid temperature change test chamber. The patent was applied for by Wuhan Bofutong Test Equipment Co., Ltd., and the authorization was announced on July 27, 2018.
Content descriptionThe invention relates to the technical field of test boxes, in particular to a walk-in high and low temperature rapid temperature change test box.
Background of the inventionThe test equipment is mainly used to perform environmental simulation tests on the physical and other related characteristics of the product under low temperature, high temperature and conditions in accordance with the requirements of national standards or user-defined requirements. After the test, the performance of the product can be judged by testing. , Whether it can still meet the predetermined requirements for product design, improvement, identification and factory inspection. The adaptability test of electronic products, their original devices, and other materials when they are stored, transported, and used in a high and low temperature environment.
The existing test box is too bulky, inconvenient to carry, it is easy to be damaged in the process of transportation, and it is laborious. At the same time, the existing test box has low efficiency, and the equipment is in high or low temperature conditions, and energy is lost during the test. Too fast is not conducive to the test, and causes great errors due to temperature changes, which affects the test results, and the existing test box structure is not strong enough, and the safety measures are also insufficient.
Therefore, how to design a walk-in high and low temperature rapid temperature change test chamber has become a problem we must solve at present.
Summary of the inventionThe present invention provides a walk-in high and low temperature rapid temperature change test box to solve the problems of insufficient safety performance, inconvenient transportation, and poor thermal insulation performance proposed in the above-mentioned background art.

The figure is a schematic diagram of the overall structure of the present invention.
In order to achieve the above objective, the present invention provides the following technical solution: a walk-in high and low temperature rapid temperature change test box, comprising a device main body, a refrigeration chamber and a heating box, the left end of the device main body is provided with an isolation layer, and the isolation The layer is tightly welded to the device body. A door handle is arranged in the middle of the device body. The door handle is fixedly connected to the device body. Both the top and bottom ends of the door handle are provided with fixing grooves. The fixing grooves are connected to the door handle. Nested connection, the left end of the door handle is provided with a heating box, the heating box is fixedly connected to the door handle, the right side of the door handle is provided with a refrigerating chamber, and the refrigerating chamber is nestedly connected to the door handle, The top of the device body is provided with a top cover, the top cover is tightly welded with the device body, an electric heating block is arranged on the top of the inner left end of the device body, and the electric heating block is closely attached to the device body. A thermal sensor is provided at the bottom end of the left side of the interior, and the thermal sensor is closely attached to the main body of the device, and a refrigerator is provided at the top end of the inner right side of the main body of the device, and the refrigerator is closely attached to the main body of the device. A low-temperature sensor is provided at the bottom of the inner right side of the device, the low-temperature sensor is closely attached to the device body, the right end of the device body is provided with a display, the display is closely welded to the device body, and the inner left side of the display is provided with An information processing device, the information processing device is electrically connected to a display, a display screen is provided on the upper right side of the display, the display screen is electrically connected to the display, and a control panel is provided at the lower end of the display screen, so The control panel is electrically connected to the display screen.
Further, a vacuum layer is provided in the middle of the device main body, and the vacuum layer is tightly welded with the device main body. The bottom end of the device main body is provided with a moving part, and the moving part is fixedly connected with the device main body. An observation window is provided in the middle of the isolation layer, and the observation window is connected to the isolation layer through. A central processing chip is provided at the right end of the information processing device, and the central processing chip is electrically connected to the information processing device. The top cover adopts a triangular structure. The isolation layer adopts a convex quadrangular pyramid structure.
Compared with the prior art, the present invention has the following beneficial effects: this kind of walk-in high and low temperature rapid temperature change test box is provided with a vacuum layer and has excellent thermal insulation performance, so that the equipment is less efficient during cooling or heating. Energy loss, and then achieve rapid heating or cooling. At the same time, the isolation layer performs cold and heat treatment together, so that when the refrigeration chamber and heating box are working at the same time, they will not be affected. The cold and heat tests are carried out at the same time to increase their work efficiency. There is a moving part, which uses rubber tires, which can move the main body of the device by human pushing. At the same time, by changing the direction of the thrust, the moving trajectory of the moving part is changed. It is convenient to move and save effort, and it is still in the process of pushing. It also has a certain shock absorption performance to ensure that the equipment will not be damaged during the movement. It is equipped with an observation window and adopts transparent and explosion-proof tempered glass. It can observe and test during operation, which is convenient for the staff who conducts the experiment to observe and quickly Make further processing plans and operate through the control panel. A central processing chip is installed. The data sensed by the thermal sensor and low temperature sensor are transmitted to the central processing unit for processing, and the processed data is displayed on the display. It is convenient and fast for personnel to analyze and organize the data from the display. The top cover adopts a triangular structure, which replaces the previous flat-top structure, which increases the test space. Due to the good stability of the triangle, the overall structure of the device is more improved. It is firm and convenient to wipe the top cover. Because it is an inclined surface, the particles are not easy to adhere to the particles. The isolation layer adopts a convex quadrangular prism structure, which increases the thickness and has thermal insulation performance. At the same time, the staff can pass through the experiment. When observing through the observation window, make sure that there is no danger of burns or frostbite.
We adopt the advanced technology imported from Europe, patented technology, specialized software to optimize the design for 11kV cast resin Dry Type Transformer. The core is made of cold-rolled grain-oriented silicon steel sheet which cut in step-lap by GEORG Germany TBA core cutting lines and laminated by the method of fifth-order step-by-step stacking technology, enabling the no-load performance of the core to improve greatly. The epoxy resin from American HUNTSMAN is adopted for the windings which casted in the vacuum resin casting machine imported from HEDRICH, Germany. The winding material ensures good permeability, no bubbles occur, which leads to minimum partial discharge. The HV and LV winding mate with each other tightly, which ensures solid strength of structure and capability to withstand short circuit and vibration. Under normal service condition, the service life of dry type transformer is 30 years. No crack will form on the surface of transformer winding due to temperature variation as long as the transformer runs under normal service condition.
