Abstract

The invention discloses a novel heat exchanger core, and belongs to the technical field of mechanical design. The novel heat exchanger core comprises etching plates, forming plates and partition plates; heat exchange runners are etched on the etching plates, and each heat exchange runner is composed of a direct runner and an oval runner which are alternatively arranged; the direct runners and the oval runners are communicated; the long axes of the oval runners and the central axes, in the liquid flowing direction, of the direct runners are located on the same straight line; the n etching plates and the m forming plates are alternatively arranged, wherein n is larger than or equal to 1, m is larger than or equal to 1, and m and n are both positive integers; the position between the etching faces of adjacent etching plates and the forming plates, the position between the two adjacent forming plates and the position between the etching faces of the two adjacent etching plates are each provided with one partition plate; according to the heat exchanger core, the characteristics of a micro-channel heat exchanger and a plate type heat exchanger are integrated, the use condition that the working medium cleaning degree is not high is met, and the novel heat exchanger core can be particularly suitable for the cooling working procedure of natural gas of an offshore work platform.

Description

technical field

[0001] The invention relates to a heat exchanger core and belongs to the technical field of heat exchange design. Background technique

[0002] At present, micro-channel heat exchangers have been widely used in ships, automobiles, air-conditioning and other industries. Due to their small size and light weight, micro-channel heat exchangers have become an important new direction of heat exchanger research and development. Due to the narrowness of the microchannel pipes, the cleanliness of the fluid working medium is high. At present, the cleanliness of the fluid working medium used in the heat exchanger is different. When the cleanliness of the working medium is not high, it often occurs Scale, or the diameter of particles in the working fluid is too large and blocked, which reduces the service life of the heat exchanger. Contents of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention provides a heat exchanger c...
