Abstract

The invention provides a heat exchanger connecting device and a heat exchanger. The heat exchanger connecting device includes a first sheet body and a second sheet body. A plurality of convex hulls are placed on the length direction of the first sheet body and the second sheet body. An opening hole matched with a heat exchange tube is arranged on the convex hulls. The first sheet body is fixed ina clamping mode with the second sheet body. The heat exchanger connecting device can reduce the manufacturing cost, meet a volume-production requirement, has high economic performance, makes the sizeof a flat tube microchannel heat exchanger increased, is not limited by the pressing forming technology size, economically solves the problem of the heat exchanger and increases the applied range of aproduct.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a heat exchanger connection device and a heat exchanger. Background technique [0002] In general, ordinary microchannels are flat rectangular heat exchangers. However, in order to increase heat transfer performance and meet different application and installation requirements, microchannel heat exchangers will also be made into large-size heat exchangers. [0003] Ordinary microchannel heat exchangers use porous flat tubes, which can be cut to any length after uncoiling. Usually, the length of flat tubes produced by molds is fixed, and limited by the size of molds and stamping equipment, the length of a single flat tube does not exceed 1.2m. , for products with a size exceeding 1.2m, such as an air-cooled modular machine heat exchanger with a length of nearly 2.0m, the new heat exchanger must use a connecting device, the purpose is to make the length of the stamped...
