Problems solved by technology

However, after the fluid is introduced into the inner cavity of the heat exchanger, since there is a gap between the heat exchange tubes of each layer of heat exchange elements, the channels between the layers are connected, and the fluid flowing in each channel converges when flowing through the gap. Cause fluid flow and affect heat transfer effect

Abstract

The invention relates to the field of heat exchange, in particular to a heat exchanger. The heat exchanger comprises a shell, a first current collecting piece, a second current collecting piece and heat exchange pieces; the shell comprises a first end and a second end, and the shell is provided with an inner cavity penetrating through the first end and the second end; the first current collectingpiece is connected with the first end, and the second current collecting piece is connected with the second end; the multiple heat exchange pieces are arranged in parallel at intervals, at least partsof the heat exchange pieces are located in the inner cavity of the shell, the inner cavity of the shell is divided into multiple first channels through the heat exchange pieces, and the first flow collecting piece communicates with the second flow collecting piece through the heat exchange pieces; and the heat exchange pieces comprise first heat exchange pipes, second heat exchange pipes and connecting parts connected between the first heat exchange pipes and the second heat exchange pipes. According to the heat exchanger, the problem that fluid flowing in different layers is converged when flowing through gaps due to layer-to-layer communication between the heat exchange pieces, and then the fluid series flow is caused is solved.

Description

technical field [0001] The present application relates to the field of heat exchange, in particular to a heat exchanger. Background technique [0002] The relevant heat exchanger arranges multi-layer heat exchange elements at intervals and in parallel in its inner cavity, so that its inner cavity is divided into multiple channels, and in order to increase the flow of refrigerant, each layer of heat exchange elements is composed of at least two rows of spaced and parallel arranged Composition of heat exchange tubes. However, after the fluid is introduced into the inner cavity of the heat exchanger, since there is a gap between the heat exchange tubes of each layer of heat exchange elements, the channels between the layers are connected, and the fluid flowing in each channel converges when flowing through the gap. Cause fluid flow, affect the heat transfer effect. Contents of the invention [0003] In view of the above problems existing in the prior art, the present applic...
