4. The control cabinet of claim 1, wherein the heat sink is a heat pipe.
5. The control cabinet according to any one of claims 1 to 4, further comprising a heat dissipation fan, wherein an air exhaust through hole is formed in a side wall of the control cabinet body, the air exhaust through hole is communicated with the accommodating cavity, the heat dissipation fan is disposed in the air exhaust through hole, and an air outlet end of the heat dissipation fan faces the accommodating cavity.
6. An air conditioner characterized by comprising the control cabinet of any one of claims 1 to 5.
7. A heat dissipation method applied to the control cabinet of any one of claims 1 to 5, characterized by comprising the following steps:
detecting the air temperature in the control cabinet;
when the temperature of air in the control cabinet is detected to be higher than a first preset temperature, a supply pipeline for supplying a first refrigerant is controlled to be communicated with a conveying pipeline for conveying the first refrigerant, so that the first refrigerant in the conveying pipeline and a second refrigerant in a flow channel can exchange heat.
8. The heat dissipation method as claimed in claim 7, wherein the step of controlling the supply pipe for supplying the first refrigerant to be in communication with the delivery pipe for delivering the first refrigerant to enable the first refrigerant in the delivery pipe and the second refrigerant in the flow passage to exchange heat when it is detected that the temperature of the air in the control cabinet is greater than a first preset temperature comprises:
when the temperature of air in the control cabinet is detected to be higher than a first preset temperature, controlling a supply pipeline for supplying a first refrigerant to be communicated with a conveying pipeline positioned on the top wall and/or the bottom wall of the accommodating cavity, so that the first refrigerant in the conveying pipeline positioned on the top wall and/or the bottom wall of the accommodating cavity can exchange heat with a second refrigerant in the flow channel;
when the control temperature in the control cabinet is detected to be higher than a second preset temperature, the conveying pipeline positioned on the top wall and/or the bottom wall of the accommodating cavity is controlled to be communicated with the conveying pipeline positioned on the circumferential side wall of the accommodating cavity, so that the first refrigerant positioned in the conveying pipeline positioned on the circumferential side wall of the accommodating cavity can exchange heat with the second refrigerant in the flow channel.
9. The method for dissipating heat according to claim 8, further comprising, prior to the step of detecting the temperature of the air within the control cabinet;
and controlling the operation of the cooling fan.
10. The heat dissipation method according to claim 7, wherein the second refrigerant is a refrigerant.
