Refrigeration device

A refrigeration device, comprising:

• an outer frame box;
• a refrigerant system, wherein a refrigerant circulates in the refrigerant system;
• a cooling liquid system, wherein a cooling liquid flows through a heating component and circulates in the cooling liquid system;
• a heat exchanger, wherein the refrigerant system and the cooling liquid system are connected to the heat exchanger, and the refrigerant and the cooling liquid exchange heat in the heat exchanger;
• a fan assembly, configured to provide power for a flow of airflow in the outer frame box;
• wherein the refrigerant system comprises a compressor, a condenser and an electronic expansion valve, and the cooling liquid system comprises a water pump, a heater, an expansion tank arranged at a water inlet end of the water pump and connection pipelines;
• the cooling liquid system, the heat exchanger, the refrigerant system and the fan assembly are sequentially arranged in the outer frame box along a flow direction of the airflow in the outer frame box;
• an air inlet is arranged in a first end face of the outer frame box, and the air outlet is arranged in a second end face of the outer frame box;
• the cooling liquid system, the heat exchanger, the refrigerant system and the fan assembly are sequentially arranged from the air inlet to the air outlet along the flow direction of the airflow;
• and
• the cooling liquid system is arranged close to the air inlet of the first end face, and the fan assembly is arranged close to the air outlet of the second end face.
