Abstract

The invention provides a heat exchanger and an air conditioner. The heat exchanger can be used as a condenser or an evaporator. Partition boards are disposed in the collector tubes so that a plurality of distribution chambers are formed in the collector tubes; a plurality of inlet tubes and outlet tubes are provided; and accordingly coolant can be distributed. When a warm room operates, vortexes formed by the coolant in the distribution chambers are sprayed up from spray holes on the distribution chambers to form jet flows, the coolant is pelletized and equally enters flat tubes, and accordingly annular flows with good heat transfer effect are formed, the parts are subjected to even heat exchange and the performance of the heat exchanger is improved. When a cold room operates, gas coolant continuously radiates heat outside through pipelines to form liquid condensate or gas-liquid flows, and the liquid condensate or gas-liquid flows enter the distribution chambers from the lower spray holes of the spray chambers in the first collector tubes and are discharged from the inlet tubes. In addition, the size of coolant pellets is reduced, impact of the coolant pellets upon the inner walls of the tubes and pellet collision are inhibited, and accordingly flowing noise of the coolant can be reduced.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning production, and more specifically relates to a heat exchanger and an air-conditioning device. Background technique [0002] In the existing parallel flow heat exchanger, in order to ensure drainage, there is a method in which flat tubes extend horizontally and headers are arranged vertically. When this method is first used as an evaporator, the following becomes the necessary functional conditions for refrigerant distribution, namely: (1) The refrigerant in the header is evenly distributed to multiple flat tubes; (2) Each space in the header is affected by gravity. The role of liquid refrigerant is difficult to stay. However, traditional heat exchangers cannot meet the two functional conditions (1) and (2) at the same time. For solutions satisfying (1), see Document-1: Japanese Patent JP1996-00957; Document-2: Japanese Patent JP2012-002475; for solutions satisfying (2), see Document-3: ...
