Description

Technical Field

[0001] This utility model relates to the technical field of battery testing equipment, and in particular to an automatic fire-extinguishing explosion-proof constant temperature chamber. Background Technology

[0002] Batteries subjected to abuse conditions such as overcharging, over-discharging, short circuits, high temperatures, and compression pose a significant risk of thermal runaway, which may be accompanied by splashing, smoke, fire, or even explosion. If such an event occurs in a conventional temperature-controlled chamber, the energy and flames will directly impact the chamber structure, easily igniting other equipment or flammable materials in the testing laboratory, leading to a catastrophic secondary accident and posing a significant threat to personnel and property safety.

[0003] Therefore, traditional ordinary constant temperature chambers are completely unable to meet the safety requirements of such high-risk tests. Currently, some fire-extinguishing and explosion-proof constant temperature chambers have appeared on the market, but their structures are more complex and their production costs are higher.

[0004] Therefore, there is an urgent need to provide an automatic fire extinguishing explosion-proof constant temperature chamber to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of this utility model is to provide an automatic fire extinguishing and explosion-proof constant temperature box, which has the advantages of automatic fire extinguishing and explosion-proof, and better structural design.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An automatic fire-extinguishing explosion-proof constant temperature chamber includes:

[0008] The enclosure is divided into at least two cavities, upper and lower.

[0009] The working component is installed in the upper cavity, has an air duct formed in it, and performs battery testing.

[0010] A cooling system is installed in the lower cavity and the air duct respectively to exchange the heat of the working cavity to the external environment;

[0011] The explosion-proof mechanism, with a lock protruding from one side of the enclosure and installed at the bottom, is opened by a shock wave to release pressure.

[0013] Preferably, the explosion-proof mechanism includes: a pressure relief door protruding from one side of the enclosure, at least two sealing rings disposed between the enclosure and the pressure relief door, a pressure relief door cover plate disposed between the sealing rings and the pressure relief door, and an opening and closing lock installed at the lower end of the pressure relief door; the upper surface of the pressure relief door is connected to the enclosure via a reinforcing chain.

[0014] Preferably, one side of the lock is designed with a set of snap-fit ​​limiting structures, and there is a gap between the two snap-fit ​​limiting structures; a corresponding limiting seat is designed on the housing to snap onto the gap.

[0015] Preferably, both of the snap-fit ​​limiting structures are formed with channels perpendicular to the gap.

[0016] Preferably, the limiting seat is T-shaped.

[0017] Preferably, the explosion-proof mechanism further includes a protective grille installed on the inner side of the insulated door of the enclosure and facing the viewing window on the insulated door.

[0018] Preferably, the refrigeration system includes: a compressor and a condenser installed in the upper cavity or the lower cavity, and an evaporator installed on the air duct; the compressor, the condenser and the evaporator are connected by connecting copper pipes to form a closed circulation system.

[0019] Preferably, the electronic control system includes: a touch screen controller located inside the air duct and snapped onto one side of the housing; a temperature sensor, a heating device, a smoke alarm, the fire extinguishing mechanism, and a buzzer installed inside the air duct.

[0022] This utility model discloses an automatic fire extinguishing and explosion-proof constant temperature box. The electrical control system executes heating operation or instructs the refrigeration system to control the temperature of the working chamber in real time based on the received information. When the pressure inside the working component is too high, the opening and closing lock of the explosion-proof mechanism is opened by the shock wave to achieve the effect of pressure relief. At the same time, the fire extinguishing mechanism of the electrical control system executes the extinguishing operation, so that this product has the function of automatic fire extinguishing and explosion-proof, and the structural design is more reasonable, effectively reducing production costs.

The viewing window 14 is a glass viewing window. The frame 11 is divided into an upper cavity and a lower cavity by a support plate.

[0037] The working component 2 includes: a working chamber 21 installed in the upper cavity; an air duct baffle 22 disposed within the working chamber 21 and separating the working chamber 21 from the air duct; adjustable louvers 23; and a ventilation plate 24. Specifically, the working chamber 21 is designed with several shelves, and the rear end face of the working chamber 21 has several openings; the explosion-proof mechanism 4 is connected to the working chamber 21. Specifically, an insulation layer is filled between the working chamber 21 and the chassis 1, and a fan is installed on the air duct baffle 22. One end of the connector is connected to the battery to be tested through the through hole, and the other end is connected to the battery charging and discharging equipment. More specifically, the adjustable louvers 23 adjust the air outlet direction to ensure uniform airflow in the working environment of the working chamber 21.

[0038] In a preferred embodiment, the refrigeration system 3 includes: a compressor 31 and a condenser 32 installed in the upper cavity, and an evaporator 33 installed in the air duct; the compressor 31, the condenser 32 and the evaporator 33 are connected by a connecting copper pipe 34 to form a closed circulation system.

[0039] The explosion-proof mechanism 4 includes: a pressure relief door 41 protruding from one side of the housing 1; at least two sealing rings 42 disposed between the housing 1 and the pressure relief door 41; a pressure relief door cover plate 43 disposed between the sealing rings 42 and the pressure relief door 41; an opening and closing lock 44 installed at the lower end of the pressure relief door 43; and a protective grille 45 installed on the inner side of the insulation door 13 and facing the viewing window 14.

Furthermore, the explosion-proof mechanism 4 of this product has a simple and reasonable structure, effectively reducing the production cost of this product. The fire extinguishing device 53 is installed in conjunction with the air duct. When the electronic control system 5 transmits the corresponding instruction, it sprays fire extinguishing gas, thereby enabling the product to have automatic fire extinguishing capabilities. The structure is well-designed.
