Problems solved by technology

[0009] When the two-phase refrigerant flows into the flat tube 4, frictional resistance will be generated due to the flow of refrigerant in the flat tube 4, which will cause pressure loss of the refrigerant
And when there is a pressure loss of the refrigerant, the heat exchange efficiency of the heat exchanger will decrease

Abstract

Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes in which a refrigerant flows, a heatsink fin coupled to the plurality of refrigerant tubes to heat-exchange the refrigerant with a fluid, a header disposed on at least one side of the plurality of refrigerant tubes to define a flow space of the refrigerant and a guide device disposed in the header to partition the flow space, the guide device guiding the refrigerant from the header to the refrigerant tubes. The guide device includes a movable cover part.

Description

technical field [0001] The present invention relates to a heat exchanger. Background technique [0002] Generally, a heat exchanger is a component used in a heat exchange cycle. The heat exchanger may be used as a condenser or an evaporator for exchanging heat between refrigerant flowing therein and an external fluid. [0003] Most heat exchangers can be classified into tube-fin type and micro-channel type according to their shape. A tube-fin heat exchanger includes a plurality of fins, and a tube having a circular or nearly circular shape passing through the fins. The microchannel heat exchanger includes a plurality of flat tubes through which refrigerant flows and fins arranged between the plurality of flat tubes. In all tube-fin and micro-channel heat exchangers, the refrigerant flowing into the tubes or flat tubes exchanges heat with an external fluid. In addition, the fins can increase the heat exchange area between the refrigerant flowing into the tubes or flat tub...
