Problems solved by technology

[0002] At present, the core body of the heat exchanger used in the base station is generally arranged perpendicular to each other by adjacent cold and hot fluid passages with a rectangular fluid flow channel. The advantages of this core structure are simple structure, easy processing and small flow resistance, but The disadvantage is that the heat transfer rate is low, which cannot meet the requirements of large heat transfer and small space.

Embodiment Construction

[0005] The present invention is described in conjunction with the following examples. The structure of the core body of the present invention is the same as that of the existing plate-fin type core body in that the passage of cold or hot fluid consists of the upper and lower partitions 2 and the gap between the two partitions. The direction of the adjacent cold fluid channel 1 and the hot fluid channel are perpendicular to each other, the partition plate 2 is made of bimetallic plates, and the aluminum fins are connected by brazing in the furnace to form a heat exchange core. The difference of the plate-fin core is that there are no sealing strips on both sides of the cold or hot fluid passage, so its weight is lighter. Since there will be fluid leakage at both sides of the fluid channel without sealing strips, but the magnitude is small and has no effect on heat transfer. This plate-fin core structure is only suitable for the case where both the hot and cold fluids are gases.

Abstract

The invention discloses a fin heat exchanger core, relates to a radiator and aims to provide a fin heat exchanger core with the advantages of high heat exchange effect and small occupied space. The technical scheme for fulfilling the aim is that: the fin heat exchanger core consists of fins arranged between parallel clapboards, and channel directions of the fins between adjacent clapboards are mutually vertical. The fin heat exchanger core is used for a heat exchanger.

Description

Technical field: [0001] The invention relates to a radiator, in particular to a core body of a plate-fin heat exchanger. Background technique: [0002] At present, the core body of the heat exchanger used in the base station is generally arranged perpendicular to each other by adjacent cold and hot fluid passages with a rectangular fluid flow channel. The advantages of this core structure are simple structure, easy processing and small flow resistance, but The disadvantage is that the heat transfer rate is low, which cannot meet the requirements of large heat transfer and small space. Invention content: [0003] The object of the present invention is to provide a plate-fin heat exchanger core with high heat exchange effect and small space occupation. The technical solution to achieve the purpose of the present invention is a plate-fin heat exchanger core, which is characterized in that it is composed of mutually parallel partitions and fins arranged between the...
