Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a vertically inserted fin microchannel heat exchanger. Background Art

[0002] Microchannel, also known as microchannel heat exchanger, is a heat exchanger with a channel equivalent diameter of 10-1000μm. There are dozens of tiny channels in the flat tubes of this heat exchanger, which are connected to circular headers at both ends. Partitions are set in the header to divide the heat exchanger flow channel into several processes.

[0003] Among them, the publication number CN203231587U discloses a microchannel parallel flow heat exchanger, including a leeward side and a windward side. The microchannel parallel flow heat exchanger includes two headers, a number of flat tubes connected between the headers and spaced parallel to each other, and a number of fins connected to the flat tubes and spaced parallel to each other. The header is arranged vertically, the flat tubes are arranged horizontally, and the fins are arranged vertically. Each fin has a number of slots on the windward side, and a number of flat tubes are inserted into the slots accordingly. The cross section of each flat tube is wedge-shaped, and the thickness of each flat tube gradually decreases from the windward side to the leeward side. The slots of the fins are adapted to the cross section of the flat tubes. When used, the airflow blows from the windward side to the leeward side, and the condensed water will flow on the fins with the airflow to the part of the fins on the leeward side, and then flow away along the part of the fins to avoid the condensed water staying on the fins.

[0004] However, there are still problems. The existing microchannel heat exchanger adopts air cooling, and the dust in the cooling process is adsorbed on the fins, resulting in low fin cooling efficiency. Water cooling lacks filtration, which causes impurities in the water to be adsorbed on the fin surface, causing cooling difficulties. Therefore, a vertically inserted fin microchannel heat exchanger is proposed to address the above problems. Utility Model Content
