Heat exchanger

Abstract

The invention discloses a heat exchanger. The heat exchanger comprises a cooling tank body, longitudinal baffle plates and an upper end cover, wherein the section of the cooling tank body is square; four groups of tubes are transversely spaced away from one another in the cooling tank body along the horizontal direction; each group of tubes longitudinally comprise at least two tubes along the horizontal direction; one longitudinal baffle plate is arranged between every two adjacent groups of tubes; the longitudinal baffle plate on the left side is arranged between the first group of tubes and the second group of tubes; the middle longitudinal baffle plate is arranged between the second group of tubes and the third group of tubes; the longitudinal baffle plate on the right side is arranged between the third group of tubes and the fourth group of tubes. The heat exchanger has the characteristics of simple structure, arrangement of a plurality of groups of tubes, small occupied space, long cooling tube pass and good cooling effect; the heat exchange contact area between a heat medium flow and a cold medium flow of the spiral tubes is increased, the hot medium flow and the cold medium flow form a reverse flow, a hot medium and a cold medium both have higher temperature difference in the entire flow process, and the heat exchange effect is good.

Description

technical field [0001] The invention relates to heat exchange equipment, in particular to a heat exchanger. Background technique [0002] At present, heat exchangers are generally used to cool the working fluid of water ring vacuum pumps. Most of the existing heat exchangers use single-row tubes. The contact area of ​​the medium is not much, and the cooling effect is not good. Contents of the invention [0003] The object of the present invention is to provide a heat exchanger with simple structure, small space occupation and long cooling tube path, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A heat exchanger, comprising a cooling tank, a longitudinal baffle and an upper end cover; the cross-section of the cooling tank is square, and four sets of tubes are arranged horizontally and transversely in the cooling tank, and each...
