Problems solved by technology

When limited by space or other reasons such as external pipelines, there is a situation where the position of the inlet and outlet interfaces is fixed, and the simple unilateral flow heat exchanger or diagonal flow heat exchanger cannot meet the requirements, and it is necessary to simultaneously Diagonal flow form and unilateral flow form exist
However, since the plate heat exchanger is stacked, different fluids need to flow in between adjacent plates, and the fluid between adjacent plates needs to be heat exchanged. Therefore, there are both diagonal flow and single flow in a plate heat exchanger. The edge flow form is more difficult
Therefore, in order to change the position of the inlet and outlet interfaces, it is generally necessary to use two plate heat exchangers, one of which is in the form of unilateral flow, and the other is in the form of diagonal flow. In this way, a flow channel transfer structure is set in the middle of the two plate heat exchangers. To change the fluid flow direction, but this method needs to use two heat exchangers, and a flow channel transfer structure part, the heat exchanger and the flow channel transfer structure are connected by pipelines, so there are many parts structures, and the tubes There are also many road connections, making the overall structure larger
In addition, the fluid enters another heat exchanger after passing through the flow channel transfer structure from one heat exchanger. Because the fluid heat exchange cannot be performed in the flow channel transfer structure, the heat exchange efficiency of the entire structure will be affected to a certain extent.

Abstract

A heat exchanger, the heat exchanger includes a heat exchanger core, the heat exchanger core at least includes a first core part, a second core part and a third core part, the first core The body part, the second core part and the third core part are stacked, and the first core part, the second core part and the third core part are formed by stacking plates, and the third core part is located at Between the first core part and the second core part, the first core part is in the form of unilateral flow, the second core part is in the form of diagonal flow, and the third core part The first core part and the second core part can realize the conversion of the flow channel form, and at the same time, the third core part is stacked with the first core part and the second core part, and the heat exchange efficiency is better.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment. Background technique [0002] According to the flow path of the heat exchange medium on the plate, the plate heat exchanger can be divided into: Figure 23 The single side flow heat exchanger shown and as Figure 24 Diagonal flow heat exchanger shown. [0003] When the plate heat exchanger determines the unilateral flow heat transfer mode or the diagonal flow heat transfer mode, the corresponding interface position of the heat exchanger is also determined. When limited by space or other reasons such as external pipelines, there is a situation where the position of the inlet and outlet interfaces is fixed, and the simple unilateral flow heat exchanger or diagonal flow heat exchanger cannot meet the requirements, and it is necessary to simultaneously There are diagonal flow forms and unilateral flow forms. However, since the plate heat exchanger is stacked, different fluids need ...
