Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The material of the hexagonal spiral channel compact heat exchanger of the present invention can be metal or non-metal material. The working process of the compact heat exchanger is as follows: the cold fluid enters the heat exchanger from the outer tube 1, passes through the cold air distribution chamber 2 and then enters the cold fluid inner channel 5, and exchanges heat with the hot fluid inner channel 4 through the rotating part in the middle of the heat exchanger. Afterwards, it is discharged from the cold fluid outer pipe 8 through the cold fluid distribution cavity. At the same time, the hot fluid enters the heat exchanger from the hot fluid outer pipe 6, enters the hot fluid inner channel 4 after passing through the hot fluid distribution chamber 7, exchanges heat with the cold fluid in the middle of the heat exchanger, and passes through the h...

Abstract

The invention relates to a compact heat exchanger with hexagonal spiral channels. The compact heat exchanger comprises a cold fluid inner channel, a heat fluid inner channel, a cold fluid distributioncavity, a heat fluid distribution cavity, a cold fluid outer pipe and a heat fluid outer pipe. The compact heat exchanger is characterized in that a cold fluid and a heat fluid conduct heat exchangethrough a plurality of staggered equilateral-triangular channels in the middle of the heat exchanger, and meanwhile, heat exchanging performance is improved through a twist structure in the middle ofthe heat exchanger. The compact heat exchanger is simple and reliable in structure and high in heat exchanging efficiency.

Description

technical field [0001] The invention belongs to the technical field of heat exchange devices, in particular to an efficient and compact heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid in a certain heat transfer method, also known as a heat exchanger. Heat exchangers have a wide range of uses in industrial production. As the world is currently facing energy shortages, heat exchangers are playing an increasingly important role. The requirement of heat exchanger is to have good reliability, high efficiency and low cost. [0003] Heat exchangers can be divided into tube type, plate type and special form according to the heat transfer surface structure. Among them, the main characteristics of the tubular heat exchanger are simple structure, low cost, and a wide range of material selection, but its heat transfer coefficient is not high and it is not easy to clean. The plate heat exchanger ...
