Circulation board of heat exchanger, heat exchanging unit of heat exchanger and heat exchanger

Abstract

The invention provides a circulation board of a heat exchanger. The circulation board of the heat exchanger comprises a pedestal and a frame positioned at the periphery of the pedestal, wherein a circulation space through which fluids can circulate is encircled by the pedestal and the frame, and the pedestal is provided with a plurality of planar holes and a plurality of convex holes protruded into the circulation space; the circulation board further comprises a clapboard positioned on the pedestal, wherein the clapboard board is used for separating the circulation space into two flow channels not communicated with each other, at least one planar hole and at least one convex hole are formed in each flow channel, and the two flow channels are used for achieving the circulation of the fluids so as to achieve heat exchange between the fluids. Thereby, according to the circulation board of the heat exchanger, the clapboard is arranged to separate the circulation space into two flow channels not communicated with each other, and the fluids flow in the separated flow channels, so that the spaces of the flow channels are more fully utilized, and thus heat exchange efficiency and heat exchange amount are improved. In addition, the invention further relates to a heat exchanging unit of the heat exchanger and the heat exchanger with the heat exchanging unit.

Description

technical field [0001] The invention relates to a circulation plate of a heat exchanger, a heat exchange unit of the heat exchanger and a heat exchanger with the heat exchange unit, belonging to the field of automobile air conditioning systems. Background technique [0002] Plate-fin heat exchanger is a type of heat exchanger, which is usually composed of partitions, fins, seals and deflectors. Fins, deflectors and seals are placed between two adjacent partitions to form a sandwich, which is the passage of fluid. Such interlayers are stacked in different ways according to actual needs, and brazed into a whole to form a plate bundle. The plate-fin heat exchanger is formed by assembling the plate bundle and the corresponding head, connecting pipe, support and other parts. [0003] A plate-fin heat exchanger is defined as a heat transfer element composed of circulation plates and fins. Fins are its core components. Common fin types are: straight, zigzag, corrugated, porous an...

AI Technical Summary

Problems solved by technology

[0005] However, the plate heat exchanger in the prior art only provides one fluid passage and can only flow one kind of fluid, so when the fluid flows in the passage, the effective space to flow through is relatively small, thus affecting The final heat transfer effect of the plate heat exchanger
