Description

Technical Field

[0001] The utility model relates to the technical field of air cooler equipment, in particular to a defrosting device for a mechanical air cooler. Background Art

[0002] As people's living standards continue to improve, people's demand for refrigeration equipment is increasing, and people's demand for cold storage has increased. Most cold storage equipment is composed of components such as compressors, throttling devices, condensers and air coolers. The function of the air cooler is to exchange heat with the air after the refrigerant flows through the evaporator, and the heat in the warehouse is transported to the outside of the warehouse through the refrigerant to achieve the purpose of refrigeration. Because the air contains water, the water in the air will condense on the fins after passing through the evaporator, which will cause the evaporator to freeze and frost, and the heat exchange efficiency will be reduced. Therefore, when the evaporator is frosted to a certain thickness, the defrost mode must be turned on. When the existing mechanical air cooler defrosts, on the one hand, the heat generated overflows into the refrigeration space, causing the warehouse temperature to fluctuate and the warehouse plate to condense; on the other hand, when the evaporator is too frozen, the defrosting efficiency is low due to the low internal temperature of the air cooler. Utility Model Content

[0003] The embodiment of the utility model provides a mechanical cold air blower defrosting device to solve the problems of low cold air blower defrosting efficiency, warehouse temperature fluctuation and warehouse plate condensation in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A defrosting device for a mechanical air cooler comprises an air outlet hood and an air outlet cover plate, wherein the air outlet hood is fixed on the air cooler casing and is used to enclose the air cooler in the air outlet hood, the air outlet hood comprises a circular air outlet, the air outlet cover plate is used to cover the circular air outlet, one end of the air outlet hood away from the air cooler is a fixing surface of the air outlet hood cover plate, the air outlet cover plate comprises a first cover plate and a second cover plate, and the sides of the first cover plate and the second cover plate close to each other are respectively fixed on the fixing surface of the air outlet hood cover plate.

[0006] Optionally, the diameter of the circular air outlet is larger than the diameter of the fan.

[0007] Optionally, the air outlet cover may be fixed to the air cooler housing in a manner including but not limited to welding, riveting, and screw connection.

[0008] Optionally, the fixed surface of the air outlet cover plate is at an angle to the vertical direction, so as to ensure that when the fan is stopped, the air outlet cover plate can naturally fall down under the action of gravity to cover the air outlet. The size of the angle is related to the size and weight of the air outlet cover plate and is adjusted according to actual conditions.

[0009] Optionally, the first cover plate and the second cover plate are fixed to the air outlet cover plate fixing surface in ways including but not limited to hinge fixing, welding, riveting, and screw connection.

[0010] Optionally, an electric heating wire is fixed to the inner side of the air outlet hood to ensure the normal opening and closing of the hinge and prevent the air outlet hood and the air outlet cover from freezing together.

[0011] Optionally, the first cover plate and the second cover plate are both semicircular, and the diameters of the first cover plate and the second cover plate are larger than the circular air outlet.

[0012] The technical solution provided by the embodiment of the utility model may have the following beneficial effects:

[0013] During refrigeration operation, the fan of the air cooler starts, and its wind force blows open the air outlet cover, allowing cold air to enter the refrigeration space smoothly; during defrosting, the fan of the air cooler stops, and under the action of gravity and a certain angle between the fixed surface of the air outlet cover and the vertical direction, the air outlet cover naturally falls to cover the air outlet, preventing the heat generated during defrosting from spilling into the refrigeration space. The use of the air outlet cover of the utility model can not only avoid the increase in storage temperature caused by the overflow of hot air during defrosting, but also shorten the defrosting time, thereby achieving energy-saving effect.
