Cooling fan with sleeve heat exchange system

Abstract

The invention discloses a cooling fan with a sleeve heat exchange system. The cooling fan comprises a first loop and a second loop; the first loop comprises wet curtain paper, a water box, a water pump and a sleeve heat exchanger which sequentially communicate in a circulation mode; the second loop comprises a compressor, a four-way valve, a condenser, a throttling device and the sleeve heat exchanger which sequentially communicate in a circulation mode; the first loop and the second loop share the same sleeve heat exchanger, the first loop is connected with a sleeve of the sleeve heat exchanger, and the second loop is connected with an inner pipe of the sleeve heat exchanger; the periphery of the wet curtain paper is provided with a first wind wheel in an opposite blowing mode, and a first fan is connected to the first wind wheel; and the periphery of the condenser is provided with a heat dissipation device in an opposite blowing mode. According to the cooling fan with the sleeve heatexchange system, the flow direction of a refrigerant in the second loop is controlled through the four-way valve, accordingly, the refrigerant is controlled to absorb or dissipate heat in the sleeveheat exchanger so that water in the first loop can be cooled or heated when flowing through the sleeve heat exchanger, the refrigerating or heating effect is achieved, the whole structure is simple, and the comfort is high.

Description

technical field [0001] The application relates to the field of cooling fans, in particular to a cooling fan with a casing heat exchange system. Background technique [0002] As a kind of household appliances, cooling fan is very common in people's life. The existing cooling fan has the function of cooling down, and it has the function of heating up by adding electric heating tube or PTC. Its structure generally includes a box body, a motor and The wind wheel driven by the motor is equipped with a water tank in the tank, and a water pump is installed in the water tank. The water pump draws the normal temperature water in the water tank and transports the water to the top of the water curtain, and evaporates and absorbs heat through the water curtain to reduce the temperature of the surrounding air. Then the motor drives the wind wheel to rotate to generate wind, which drives the cooled air to blow out of the box to achieve the purpose of cooling. There is a heating module at...
