It is usually made of metal and has multiple slots that can accommodate circuit breakers of different specifications. Circuit breaker installation cabinets are mainly used to distribute power and provide overload and short-circuit protection to ensure the safe operation of electrical systems. Circuit breakers will generate a certain amount of heat during normal operation. When the current inside the circuit breaker passes through the wires and contacts, resistance will occur. The energy generated by the resistance will be converted into heat. Therefore, when the circuit breaker is in operation, its temperature will rise.

[0003] However, the above device still has the following problems during implementation:

[0004] The prior art causes the circuit breaker to generate a certain amount of heat during normal operation. However, the circuit breaker installation cabinet generally dissipates heat through the heat dissipation holes on both sides of the cabinet body. When the circuit breaker generates heat, the heat rises and accumulates on the top of the inner cavity of the installation cabinet, and is not easy to be discharged from the heat dissipation holes on both sides of the cabinet body. As the temperature inside the circuit breaker installation cabinet continues to rise, the circuit breaker may burn out. Therefore, a circuit breaker installation cabinet with good heat dissipation effect is proposed to solve the above problems. Utility Model Content

[0030] The above solution is adopted: by setting the L-shaped shell 11 and the coil 12, the wind force generated by the exhaust fan 8 when rotating will pass through the coil 12 and enter the cabinet 1, and the coolant in the coil 12 can cool the wind.

[0031] refer to Figure 3 The left side of the coil 12 is fixedly connected with an L-shaped tube 13 , the top of the L-shaped tube 13 is fixedly connected with a coolant storage box 14 , and the right side of the coolant storage box 14 is fixedly connected to the cabinet 1 .

[0032] The above solution is adopted: by setting an L-shaped tube 13 and a coolant storage box 14, when the coolant needs to be introduced into the coil 12, the coolant is added into the coolant storage box 14, and then the coolant enters the coil 12 through the L-shaped tube 13.

[0039] The working principle of this utility model:

The two exhaust fans 8 rotate to draw wind into the L-shaped shell 11, and the hot air from the outside passes through the coil 12 and is converted into cold air by the coolant in the coil 12. The cold air enters the cabinet 1 and blows the heat generated by the circuit breaker to the top of the inner cavity of the cabinet 1. At this time, the radiator 42 can quickly discharge the rising hot air, which solves the problem that the circuit breaker installation cabinet generally dissipates heat through the heat dissipation holes 41 on both sides of the cabinet 1 when dissipating heat, and when the circuit breaker generates heat, the heat rises and accumulates at the top of the inner cavity of the installation cabinet, and is not easy to be discharged from the heat dissipation holes 41 on both sides of the cabinet 1. As the temperature inside the circuit breaker installation cabinet continues to rise, the circuit breaker may burn out.
