Laminated board fin structured heat exchanger with medium equipartition device

Abstract

The invention relates to a laminated board fin structured heat exchanger with a medium equipartition device. An angle hole plane on a first diagonal is arranged on a high plane, an angle hole plane on a second diagonal is arranged on a low plane, and bosses surrounding the first angle hole and the third angle hole are formed at the peripheries of the angle hole planes of a first angle hole and a third angle hole; the angle hole planes of the first angle hole and the third angle hole on the first diagonal on a second baffle are arranged on the low plane; the angle hole planes of a second anglehole and a fourth angle hole on the second diagonal are arranged on the high plane; the bosses surrounding the second angle hole and the fourth angle hole are formed at the peripheries of the angle hole planes of the second angle hole and the third angle hole; the equipartition devices are arranged at the peripheries of the upper surfaces of the second angle hole on the second diagonal of the first baffle and the first angle hole on the first diagonal of the second baffle; ring-shaped jacking columns are arranged at the peripheries of the upper surfaces of the fourth angle hole on the second diagonal of the first baffle and the third angle hole on the first diagonal of the second baffle; and the heights of the equipartition devices and the ring-shaped jacking columns are equal to those ofthe inner sides of the bosses.

Description

technical field [0001] The invention relates to a laminated plate-fin structure heat exchanger with a medium equalizer, which is suitable for central air conditioners and freeze dryers. Background technique [0002] The plate-fin heat exchanger is a common compact heat exchanger, which is mainly composed of a core, a head, a connecting pipe and a support. The most critical part is the exchange core of a series of structural units. Each structural unit is composed of a partition, an annular top column, an equalizer, fins and pipe joints. The general plate-fin heat exchange There is a phenomenon that the fluid medium is not uniformly dispersed and the heat exchange effect is not good. Contents of the invention [0003] The present invention aims at the above problems, improves the structure of the traditional plate-fin heat exchanger, and proposes a stacked plate-fin heat exchanger with an equalizer. There are equal dividers on the top, which can make the medium flow evenl...
