Embodiment 1

[0040] A heat exchanger core for heat exchange of more than three kinds of fluids includes 3 heat exchange plate groups, and is formed by stacking the 3 heat exchange plate groups alternately; each of the heat exchange plate groups carries A heat exchange fluid, that is, the core of the heat exchanger includes three kinds of heat exchange fluid; the heat exchange plate includes a through-hole heat exchange plate and a through-hole heat exchange plate; the through-hole heat exchange plate includes a through-hole base, Two fluid via holes and heat exchange flow channels processed on the via hole substrate by chemical etching; the ports of the heat exchange flow channels on the hole heat exchange plate are located on the side of the via hole heat exchange plate, as the heat exchange fluid The inlet of the fluid; the two fluid through holes are used as the outlet of the heat exchange fluid corresponding to the port properties of the heat exchange flow channel on the through hole he...

Embodiment 2

[0047] The difference between embodiment 2 and embodiment 1 is that a heat exchanger core for heat exchange of more than three fluids includes 8 heat exchange plate groups, and the 8 heat exchange plate groups are stacked alternately Among them, the alternate stacking of heat exchange plate groups means that the heat exchange plate group adjacent to any heat exchange plate group in the core of the heat exchanger is any heat exchange plate except itself Group. Each heat exchange plate group carries a heat exchange fluid, that is, the core of the heat exchanger includes 8 heat exchange fluids. The port of the heat exchange flow channel on the hole heat exchange plate is located on the side of the through hole heat exchange plate, as the outlet of the heat exchange fluid; the two fluid through holes serve as the connection with the heat exchange flow channel on the through hole heat exchange plate The port attribute corresponds to the inlet of the heat exchange fluid; the expose...

Embodiment 3

[0050] The difference between embodiment 3 and embodiment 1 and embodiment 2 is that a heat exchanger core for heat exchange of more than three fluids includes 15 heat exchange plate groups, and consists of 15 heat exchange plates Sheet groups are stacked alternately, where the alternate stacking of heat exchange plate groups means that the heat exchange plate group adjacent to any heat exchange plate group in the core of the heat exchanger is any other than itself. Heat exchange plate group. Each heat exchange plate group carries a heat exchange fluid, that is, the core of the heat exchanger includes 15 heat exchange fluids. Cover plates are arranged outside the two exposed heat exchange plate groups after being alternately stacked, and there is a partition or no partition between any cover plate and the adjacent heat exchange plate group. The heat exchange channels of the through-hole substrate, the cold plate substrate and the hot plate substrate are all located on both si...

Abstract

The invention provides a heat exchanger core for heat exchange of three or more fluids, and belongs to the technical field of heat exchange design. The heat exchanger core comprises n heat exchange plate groups and is formed by alternately stacking the n heat exchange plate groups which bear n heat exchange fluids; each heat exchange plate comprises a via hole heat exchange plate and a through hole heat exchange plate; each via hole heat exchange plate comprises a via hole matrix, two fluid via holes and a heat exchange flow channel machined on the via hole matrix through chemical etching; each through hole heat exchange plate comprises a cold plate and a hot plate, wherein the cold plate comprises a cold plate matrix, a fluid through hole and a heat exchange flowing channel machined on the cold plate matrix through chemical etching, and the hot plate comprises a hot plate matrix, a fluid through hole and a heat exchange flowing channel machined on the hot plate matrix through chemical etching; each heat exchange plate group comprises one or more cold plate or hot plates. The heat exchanger core for heat exchange of the three or more fluids has the advantages of being high in cooling efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of heat exchange design, and in particular relates to a heat exchanger core used for heat exchange of more than three fluids. Background technique [0002] At present, micro-channel heat exchangers have been widely used in ships, automobiles, air-conditioning and other industries.
