A C-type hair-fin condenser

Abstract

The invention relates to a C-type hair-fin condenser, which includes fins and refrigeration pipes, and the outer wall of the refrigeration pipes is spirally wound with fins; the fins include horizontal heat-absorbing parts, bent ribs and vertical The heat dissipation part, the extension line of the lower end of the vertical heat dissipation part is perpendicular to the horizontal heat absorption part, and the vertical heat dissipation part and the horizontal heat absorption part are integrally bent by bending the reinforcing rib part, and the bending reinforcing rib part is an arc surface structure , one end of the bent rib is connected horizontally to the horizontal heat sink, the other end of the bent rib is vertically integrated with the vertical heat sink, the joint between the bent rib and the vertical heat sink is a chamfered structure, and the vertical heat sink There are several vertical slits equidistant in the length direction, and the upper end of the vertical heat dissipation part is bent to form a horizontally placed C-shaped arc surface; the invention ensures smooth heat exchange channels, increases the heat exchange area with the air, and avoids The scratches on human hands reduce potential safety hazards.

Description

technical field [0001] The invention relates to a refrigeration and heat dissipation device, in particular to a C-type hair-fin condenser. Background technique [0002] Existing air-cooled refrigerators, double-door, three-door, frost-free refrigerators and other luxury air-cooled refrigerators are increasingly occupying the main position in the refrigerator market. The volume of refrigerators and refrigeration requirements have increased, and the heat exchange of radiators or condensers during the refrigeration process The efficiency requirement is even higher. The spiral plate tube type with ordinary steel plate winding or the wire tube type condenser with steel wire steel tube welded structure can no longer meet the needs of the development of the refrigerator and radiator industry. Condensers with smaller volume and higher heat dissipation efficiency are needed. or the radiator appears. [0003] Chinese patent application number 201220341059.3, application date: July 16...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned patent application has the flange and the contact surface of the heat pipe fixed, which increases the contact area between the fin and the heat pipe, the upper part of the fin is a sheet structure. Opening, when spirally wound, the sheet fins will inevitably be twisted toward one end of the heat pipe, and the upper parts of the twisted fins will overlap and cover each other. The channel for the hot air to disperse is blocked, and it is difficult for the hot air to diffuse outward, which greatly reduces the heat exchange. efficiency, and the upper end surface of the fin is a helical line, and the upper end surface of the fin is narrow and sharp, which can easily cut the operator's hand and bring safety hazards
