Air cooler for finned flat tube integrated structure

Abstract

The invention discloses an air cooler for a finned flat tube integrated structure. The air cooler comprises a frame and at least one group of heat exchange modules which are arranged in the frame; each heat exchange module comprises a plurality of flat tubes and flat tube fins, wherein the flat tubes are arranged in parallel; the internal section of each flat tube is of a rectangular structure; the flat tube fins are formed on the flat tubes; the size of the rectangular area of the internal section of each flat tube is sequentially reduced from one side to the other side; every adjacent flat tubes are connected by a reducing bent tube to form a structure in an S-shaped direction; the flat tubes and the flat tube fins form a single integrated structure formed by overall cold-machining formation; the other end of one flat tube positioned at one side is connected with an air collecting tube; and the other end of another flat tube positioned at the other side is connected with a liquid supply pipe. According to the air cooler disclosed by the invention, the finned flat tube integrated structure is machined by adopting a cold-extrusion drawing way, thus contact heat resistance of the fins and a circular tube is eliminated, the heat transfer effect is improved, water generated by defrosting is cleared completely, heat transfer temperature difference is reduced, and the thermal performance of a refrigeration system is improved.

Description

Technical field [0001] The invention relates to the technical field of freezing, refrigeration and refrigeration, and in particular to a cooling fan with a finned flat tube integrated structure. Background technique [0002] The air cooler has a fast cooling speed and a uniform air flow in the cold room. Therefore, it is widely used in refrigeration and refrigeration equipment. The usual freon refrigeration system is a fin and tube heat exchanger, and the fin and tube are separated. Contact thermal resistance, but it is still difficult to avoid the existence of contact thermal resistance, resulting in a reduction in heat transfer coefficient and a decline in the performance of the refrigeration system. At the same time, it is easy to form frost and the defrost water is not cleaned thoroughly. Summary of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a cooling fan with an integrated fin flat tube structure, so as to imp...

Problems solved by technology

[0002] The air cooler has a fast cooling speed and uniform airflow in the cold room, so it is widely used in refrigeration equipment. The usual Freon refrigeration system is a sleeve-tube heat exchanger. Contact thermal resistance, but it is still difficult to avoid the existence of contact thermal resistance, resulting in a decrease in heat transfer coefficient and a decline in the performance of the refrigeration system. At the same time, it is easy to frost, and the defrosting water is not cleaned thoroughly.
