Liquid homogenizing device and air conditioner

Abstract

The invention belongs to the technical field of heat exchange, and aims at solving the problems that an existing air conditioner has high requirements for the assembly precision of a liquid homogenizing device, and the dry burning phenomenon of a heat exchange tube bundle of the air conditioner cannot be thoroughly solved. To achieve the purpose, the invention provides the liquid homogenizing device. The liquid homogenizing device comprises a pressure box, an upper box, a lower box and at least one layer of middle baffle arranged between the upper box and the lower box, wherein the pressure box is arranged in the length direction of the upper box, and a plurality of liquid holes are uniformly distributed in a bottom plate of the pressure box, middle baffles and the lower box; a plurality of first liquid baffles are arranged on the middle baffles, so that each middle baffle is divided into a plurality of first liquid film uniform sections; and a plurality of second liquid baffles are arranged on the lower box, so that the lower box is divided into a plurality of second liquid film uniform sections. The liquid homogenizing effect of the liquid homogenizing device can be improved, theassembling precision requirement of the liquid homogenizing device is lowered, the dry burning phenomenon caused by uneven distribution of refrigerants on the heat exchange tube bundle is avoided, the utilization rate of heat exchange tubes is increased, and then the performance of the air conditioner is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, and specifically provides a liquid equalizing device and an air conditioner. Background technique [0002] At present, the evaporators used in central air-conditioning chillers mainly include dry evaporators, flooded evaporators and falling film evaporators. Compared with dry evaporator and flooded evaporator, falling film evaporator has the advantages of higher heat transfer coefficient than dry evaporator and less refrigerant charge than flooded evaporator, but all the above advantages are established On the basis that the refrigerant can be evenly distributed. Usually, the refrigeration unit adopts a single liquid inlet, and is limited by the position of the suction port of the compressor. The liquid inlet is usually placed at one end of the liquid equalizing device, so that the refrigerant cannot be evenly distributed along the length or width of the liquid equalizing device. In turn,...
