Abstract

To provide a small-sized and high-performance heat exchanger in which heat exchange efficiency is improved by equalizing a fluid branched flow rate to a first fluid flow passage from a header flow passage on an inlet side, and a refrigeration system using the same.A fluid collision part 17 is provided on a first fluid flow passage group side of a connection flow passage 10b for connecting a headerflow passage 10 on an inlet side and a first fluid flow passage 11 group, and a multiple-branching flow passage 10c is provided for guiding the fluid dispersed by colliding with the fluid collision part to the first fluid flow passage group. Thereby, a refrigerant from the connection flow passage of the header flow passage on the inlet side collides with the fluid collision part and disperses, and flows to the first fluid flow passage group from the multiple-branching flow passage, it is branched uniformly in each of the first fluid flow passages and heat exchange efficiency improves. Thus, asmall-sized heat exchanger with high heat efficiency can be achieved.

Description

technical field [0001] The present invention relates to a heat exchanger and a refrigeration device using the same, and more particularly to a plate-fin stacked heat exchanger formed by stacking plate-like fins through which a refrigerant flows, and a refrigeration device using the same. Background technique [0002] In general, refrigeration equipment represented by air conditioners and refrigerators circulates refrigerant compressed by a compressor through a heat exchanger represented by a condenser and an evaporator to exchange heat with indoor air to supply air. cold or heated. However, the performance and energy saving of the device are greatly influenced by the heat exchange efficiency of the heat exchanger. Therefore, there is a strong demand for high efficiency of heat exchangers. [0003] Among them, the heat exchanger of the refrigeration device generally uses a finned tube type heat exchanger formed by passing through the heat transfer tube in the fin group, and...
