It is used to blow hot air inside the testing chamber to the outside of the cabinet (1) when the dustproof component (3) closes the testing chamber. The technical problems are: the temperature of the testing chamber near the heat dissipation component is different from the temperature of other testing chambers, which affects the temperature uniformity. The testing chamber far from the heat dissipation component will generate heat during battery testing, which will lead to local high temperature and cause test errors in battery testing. Utility Model Content
[0005] The purpose of this utility model is to provide a constant temperature test cabinet for button batteries.
[0006] This utility model is implemented by the following technical solution: a button battery constant temperature test cabinet, which includes a box body, a switch door on the front wall of the box body, and a mounting plate vertically fixed inside the box body between the front wall and the rear wall of the box body, the mounting plate dividing the box body into a gas circulation chamber and a test chamber;
[0007] The gas circulation chamber is equipped with a supply fan and a return fan. The supply fan is fixedly connected to the top of the mounting plate, and the return fan is fixedly connected to the bottom of the mounting plate. The outlet of the supply fan and the inlet of the return fan are respectively connected to the interior of the test chamber.
[0008] The test chamber has multiple horizontally arranged perforated plates arranged from top to bottom inside, and the perforated plates are fixedly connected to the inner wall of the test chamber.
[0009] The test chamber is also equipped with vertically arranged horizontal and vertical partitions. The horizontal partition is positioned opposite to the outlet of the fan, and a horizontal air supply channel is formed between the horizontal partition and the outlet of the fan. A base plate is fixed to the bottom end of the horizontal air supply channel. The horizontal partition is fixedly connected to the surface of the adjacent perforated plate.

[0010] Furthermore, a buffer channel is formed between the perforated plate and the switch door.
[0011] Furthermore, the gas circulation chamber is also equipped with a heater and a cooler, which are fixedly connected to the inner wall of the gas circulation chamber.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-4 As shown, the button battery constant temperature test cabinet includes a box body 1, a switch door 2 on the front wall of the box body 1, and a mounting plate 3 vertically fixed inside the box body 1 between the front wall and the rear wall of the box body 1. The mounting plate 3 divides the box body 1 into a gas flow chamber 4 and a test chamber 5.
[0026] The gas circulation chamber 4 is equipped with a supply fan 6 and a return fan 7. The supply fan 6 is fixedly connected to the top of the mounting plate 3, and the return fan 7 is fixedly connected to the bottom of the mounting plate 3. The outlet of the supply fan 6 and the inlet of the return fan 7 are respectively connected to the interior of the test chamber 5. The gas circulation chamber 4 is also equipped with a heater 8 and a cooler 9. The heater 8 and the cooler 9 are respectively fixedly connected to the inner wall of the gas circulation chamber 4.
[0027] A temperature sensor 10 is installed in the test chamber 5. Depending on the temperature, the heater 8 or the cooler 9 is activated. The hot or cold air in the airflow chamber is sent to the test chamber 5 through the supply fan 6 and the return fan 7 to regulate the temperature inside the test chamber 5.
[0028] Inside the test chamber 5, there are multiple horizontally arranged perforated plates 11 arranged from top to bottom. The perforated plates 11 are fixedly connected to the inner wall of the test chamber 5, and the batteries to be tested are placed on the perforated plates 11.
[0029] The test chamber 5 is also equipped with a vertically arranged transverse partition 12 and a longitudinal partition 13. The transverse partition 12 is positioned opposite to the outlet of the fan 6. A transverse air supply channel 14 is formed between the transverse partition 12 and the outlet of the fan 6. A base plate 15 is fixed to the bottom end of the transverse air supply channel 14. The transverse partition 12 is fixedly connected to the surface of the adjacent perforated plate 11. A longitudinal partition 13 is provided at one end of the transverse partition 12. A longitudinal air supply channel 16 is formed between the longitudinal partition 13 and the side wall of the adjacent chamber 1. The longitudinal air supply channel 16 is connected to the transverse air supply channel 14. The longitudinal partition 13 is fixedly connected to the surface of the adjacent perforated plate 11.
[0030] A buffer channel 17 is formed between the perforated plate 11 and the switch door 2, which facilitates the formation of an enveloping airflow.
[0031] Specifically, under the action of the transverse air supply channel 14, the direct blowing of the air supply fan 6 is reduced, and the airflow is guided to the longitudinal air supply channel 16. Then, under the action of the longitudinal air supply channel 16, it enters the buffer channel 17. The airflow impacts the switch door 2, causing the airflow to disperse in an encircling shape and enter each battery housing space, ensuring the uniformity of temperature at each position on the perforated plate 11.
[0032] The test chamber 5 includes eight perforated plates 11. In this embodiment, eight perforated plates 11 are arranged. The fan 6 is positioned opposite to the first perforated plate 11.1. The first and second perforated plates 11.1 and 11.2 are respectively fixedly connected to the transverse partition 12. A base plate 15 is fixed between the second perforated plate 11.2 and the mounting plate 3. The first to fourth perforated plates 11.4 are respectively fixedly connected to the longitudinal partition 13. The purpose of the eight perforated plates 11 is that the upper four perforated plates 11 can utilize an enveloping airflow for temperature control, while the airflow evenly enters each upper perforated plate 11, ensuring the same temperature control effect for each layer. The airflow entering the upper four perforated plates 11 is then directed by the return fan 7 to the lower four perforated plates 11, where the lower four perforated plates 11 utilize vertical airflow for temperature control.
[0033] The specific operation process of this embodiment is as follows:
[0034] A temperature sensor 10 is installed in the test chamber 5. Depending on the temperature, the heater 8 or the cooler 9 is activated to heat or cool the airflow in the airflow circulation chamber. Then, the airflow is sent into the test chamber 5 by the fan 6. After passing through the transverse air supply channel 14, the longitudinal air supply channel 16, and the buffer channel 17, the airflow enters the battery placement area between two adjacent perforated plates 11 on the upper 4 layers. As the airflow enters the buffer channel 17, it impacts the switch door 2, causing the airflow to disperse and enter each battery holding space in a ring shape, ensuring the uniformity of temperature at each position on the perforated plate 11.
[0035] The airflow from the top four perforated plates 11 enters the bottom four perforated plates 11 under the action of the return fan 7. The bottom four perforated plates 11 use vertical airflow to control the temperature. There are two return fans 7 below, and the cold air will naturally form convection with the hot air. The cold air will naturally sink and the hot air will rise, so the heat exchange effect is better. The return fan 7 sends the cooled or heated airflow to the airflow circulation chamber, and it is circulated after being processed by the heater 8 or the cooler 9.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
