Fig. 2 is an enlarged schematic view of the structure of the two-way seal.

In the figure: 1. an inlet and outlet corner hole; 2. a flow guide area; 3. a heat exchange zone; 4. a shunting region; 5. sealing for the second time; 6. an inner seal strip; 7. a suspension groove; 8. sealing the groove.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The plate heat exchanger with the heat transfer plate with the enhanced two sealing washer supporting surfaces shown in fig. 1 comprises a heat transfer plate main body, wherein the heat transfer plate main body comprises an inlet and outlet corner hole 1, a flow guide area 2 is arranged in the direction from the inlet and outlet corner hole 1 to the center of the heat transfer plate main body, a heat exchange area 3 is arranged in the center of the heat transfer plate main body, a flow distribution area 4 is arranged between the heat exchange area 3 and the flow guide area 2, and a two-way seal 5 and an internal sealing strip 6 are also arranged between the flow distribution area 4 and the flow guide area 2;

as shown in fig. 2, the two seals 5 are elongated grooves, the two seals 5 and the inner seal strip 6 are respectively located at two sides of the diversion area 4, the two seals 5 include two seals, and the two seals are symmetrical with respect to the heat exchange area 3.

The inlet and outlet corner holes 1 comprise four, the four inlet and outlet corner holes are respectively located at four corners of the heat transfer plate main body, the flow guide areas 2 correspond to the inlet and outlet corner holes 1, the flow guide areas 2 are also four, the flow distribution areas 4 comprise two flow distribution areas, the two flow distribution areas are respectively located at the upper end and the lower end of the heat exchange area 3, the suspension grooves 7 are respectively formed in the upper end and the lower end of the heat transfer plate main body, and the sealing grooves 8 are respectively formed in the left end and the right end.

When the plate heat exchanger is used, the heat transfer plates are firstly stacked, although the traditional heat transfer plates are provided with some sealing measures, however, the seal is arranged around the heat transfer plates, which results in the middle of the heat transfer plates being free of external force seals, when in use, the liquid leakage phenomenon is easy to occur, therefore, the utility model adds two seals on the basis of basic sealing, the two seals are strip-shaped grooves with the depth of 1-3mm when seen from the front side of the heat transfer plate, the two seals are strip-shaped bulges with the depth of 1-3mm when seen from the back side of the heat transfer plate, when the heat transfer plate is stacked, the two sealing bulges of the front heat transfer plate can be tightly clamped in the two sealing grooves of the rear heat transfer plate, the structure of the two seals enables the heat transfer plates to be combined more tightly, and improves the sealing performance of the middle parts of the heat transfer plates.
