Description

Condenser for evaporative cooling air conditioner main unit

Technical Field

The utility model relates to a condenser for an evaporative cooling air conditioner host, in particular to a condenser with winding sheets on a U-shaped heat exchange tube.

Background

The condenser for the traditional evaporative cooling air conditioner host is generally composed of U-shaped heat exchange tubes, in order to meet the requirement of a certain heat exchange area, the defects of large quantity of required heat exchange tubes and large volume of the condenser exist, and after water-quality secondary refrigerant is sprayed on the U-shaped heat exchange tubes from the outside, namely the upper side of the condenser, short circuit is easily formed in gaps among the U-shaped heat exchange tubes, the water-quality secondary refrigerant is not fully evaporated and flows away under the action of gravity, and the evaporation area of the water side on the surface of the heat exchange tubes is limited; the refrigerant is not fully condensed, so that the defects of high condensing pressure, small cold quantity, insufficient heat exchange between the refrigerant and the water-quality secondary refrigerant and the like are caused directly.

Disclosure of Invention

In order to solve the defects of the traditional condenser, the utility model provides the condenser for the evaporative cooling air conditioner host, the spiral winding sheet is additionally arranged outside the U-shaped heat exchange pipe, the heat exchange area of the evaporative condenser is increased in an auxiliary manner, the heat exchange is sufficient, the blockage is not easy, and the short circuit problem of water-quality secondary refrigerant among the U-shaped heat exchange pipes of the evaporative condenser is effectively avoided.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the condenser for the evaporative cooling air conditioner host is mainly composed of end plates, U-shaped heat exchange tubes, winding sheets, a protective plate, a refrigerant inlet and a refrigerant outlet, wherein spiral winding sheets are additionally arranged outside the U-shaped heat exchange tubes, the distance between the winding sheets is 10-20mm, and the thickness of the winding sheets is 0.5-1 mm; two ends of the U-shaped heat exchange tube penetrate through the end plates, and the end plates and the guard plate are connected into a whole; the U-shaped heat exchange tube and the winding sheet are made of anti-corrosion materials.

The working process of the utility model is as follows: high-temperature and high-pressure refrigerant gas discharged from the compressor enters the U-shaped heat exchange tube from a refrigerant inlet of the condenser, and is fully released by the U-shaped heat exchange tube and the winding sheet; the water-quality secondary refrigerant is uniformly sprayed on the U-shaped heat exchange tubes and the winding sheets from the outside of the heat exchanger, and absorbs the heat emitted by the refrigerant to be fully evaporated into vapor under the power of the fan; meanwhile, the high-temperature and high-pressure refrigerant gas is condensed into liquid and flows out of the refrigerant outlet.

The utility model has the beneficial effects that: the utility model provides a condenser for evaporative cooling air conditioner host computer adds the spiral winding piece outside the U type heat transfer pipe, and the supplementary heat transfer area that has increased evaporative condenser, the heat transfer is abundant, is difficult for blockking up, and has effectively avoided the short circuit problem of quality of water secondary refrigerant between evaporative condenser U type heat transfer pipe.

The utility model can be widely applied to the condenser for the central air-conditioning host.
