Embodiment 1

[0044] combine Figure 1-7 , this embodiment provides a heat exchanger core for heat exchange of three fluids, including two cover plates 1, a first etched plate 2, a second etched plate 3, a formed plate 4, and a partition 5 , baffle plate 6; forming plate 4 and partition 5 constitute structural unit A, first etched plate 2 and second etched plate 3 constitute structural unit B; structural unit A and structural unit B are between two cover plates 1 Alternately stacked; the non-etched surface of the first etched sheet 2 is abutted with the etched surface of the second etched sheet 3; the etched surface of the first etched sheet 2 is abutted with the partition 5 of the adjacent structural unit A; molding One side of the plate 4 is in contact with the partition 5, and the other side is in contact with the non-etched surface of the second etched plate 3 of the adjacent structural unit B; a partition 5 is arranged between the cover plate 1 and the forming plate 4; A partition 5 i...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that two cover plates 1, the first etched plate 2, the second etched plate 3, the formed plate 4, the partition plate 5 and the baffle plate 6 are processed into a cuboid; the formed plate 4 is a rectangle, and the inlet and outlet of its flow channel are arranged on the long sides of the rectangle; the first etched sheet 2 and the second etched sheet 3 are all rectangular, and the inlets and outlets of their flow channels are all arranged on the wide sides of the rectangle and Stagger each other.

Embodiment 3

[0053] The difference between this embodiment and embodiment 1 is that two cover plates 1, the first etched plate 2, the second etched plate 3, the forming plate 4, the partition plate 5 and the baffle plate 6 are processed into a cube; The first etched sheet 2, the second etched sheet 3 and the formed sheet 4 are all square, and the inlets and outlets of their flow channels are arranged on different sides of the square and staggered from each other.

[0054] The etched sheets (the first etched sheet 2 and the second etched sheet 3) described in the present invention process flow passages of different forms on the sheets by chemical etching, and the flow passages can be straight passages or flow passages. Zigzag flow channel, the flow channel inlet and outlet of the etched plate can be located at any position around the plate through the guide channel, the etched plate 3 is suitable for the working medium with a high degree of fluid cleanliness, and the flow channel size proces...

Abstract

The invention discloses a heat exchanger core used for heat exchange of three fluids, belonging to the technical field of mechanical design. The heat exchanger core includes two cover plates, the first etched plate, the second etched plate, the formed plate and the partition; the formed plate and the partition constitute the structural unit A, the first etched plate and the second The etched plates form the structural unit B; the structural unit A and the structural unit B are stacked alternately between the two cover plates; the two cover plates, the first etched plate, the second etched plate, the forming plate and the partition are processed into one. The core of the heat exchanger of the present invention combines the characteristics of the microchannel heat exchanger and the plate heat exchanger, can realize simultaneous heat exchange between the three fluids, and can meet the operating conditions of low cleanliness of the working medium.

Description

technical field [0001] The invention relates to a heat exchanger core used for heat exchange of three fluids, 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 for the research and development of heat exchangers today. How can they be It is the focus of current research and development to better realize the heat exchange of multiple fluids. [0003] Usually, the cleanliness of the fluid working fluid used in heat exchangers is different. When using a working fluid with a low cleanliness, it often occurs due to fouling in the flow channel or blockage due to excessive particle diameter in the working fluid, reducing the the service life of the heat exchanger. Contents of the invention [0004] In orde...
