JPH04129683U - Heat exchange plate of plate heat exchanger - Google Patents

Abstract

(57) [Summary] [Purpose] The purpose is to provide a heat exchange plate for a plate heat exchanger that is designed to improve washability, shorten cleaning time, and reduce labor and running costs. [Structure] In the gasket mounting groove 1, the opening edge 3 of the inner side wall 2 is lower than the opening edge 5 of the outer side wall 4, and the heat transfer surface 6
In this case, a portion 7 along the opening edge 3 of the inner side wall 2 is sloped so that it gradually becomes higher as it approaches the gasket mounting groove 1.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention has a fixed method of supplying cleaning liquid at a predetermined temperature and flow rate without disassembling the device. Regarding heat exchange plates of plate heat exchangers used in stationary cleaning systems. Ru.

0002

[Conventional technology]

Conventionally, as shown in FIG. 2, the opening edge of the inner side wall 2 and the opening edge of the outer side wall 4 are Heat exchange plates of elevated plate heat exchangers are widely known.

0003

[Problem that the idea aims to solve]

The heat exchange plate of the plate heat exchanger described in the above conventional technology is For example, if the next heat exchange plate is stacked on top of the previous heat exchange plate, as shown in Figure 2. As shown, the opening edge 3 of the inner side wall 2 of the front heat exchange plate is connected to the next heat exchange plate. It was in contact with the lower surface of the bottom wall of the gasket mounting groove 1 in the plate. deer However, this contact is not necessarily done tightly, and the Shapes or fibers were caught or stuck deep inside. For this reason, washing Cleanliness is poor and cleaning takes a relatively long time, reducing labor and running costs. It was expensive.

0004 This invention improves cleaning performance, shortens cleaning time, and reduces labor costs and running costs. We aim to provide a heat exchange plate for a new plate heat exchanger that has been devised to purpose.

[0005]

[Means to solve the problem]

In order to achieve the above object, a heat exchange plate for a plate heat exchanger according to the present invention is provided. In the gasket mounting groove 1, the opening edge 3 of the inner side wall 2 is connected to the opening edge of the outer side wall 4. It is lower than 5.

[0006] A portion 7 of the heat transfer surface 6 that extends continuously along the opening edge 3 of the inner side wall 2. is a slope that gradually increases as it approaches the gasket mounting groove 1. .

[0007]

【Example】

The embodiment of the present invention shown in Fig. 1 is obtained by applying pressure drawing to a thin metal plate. In the figure, 8 indicates a gasket, and 9 indicates a reinforcing contact portion.

[0008]

[Effect]

As is clear from Figure 1, the heat exchange plate according to the present invention is In this case, the opening edge 3 of the inner side wall 2 is fitted with a gasket in the next heat exchange plate. Since there is no contact with the lower surface of the bottom wall of groove 1 and a relatively wide gap S is created, the passage of the cleaning liquid is improved. The cleaning liquid that hits the inclined portion 7 causes turbulent flow and enters the gap S to remove the stagnation. Erase

[0009]

[Effect of the idea]

The heat exchange plate of the plate heat exchanger according to the present invention has the above structure. Therefore, when used in an overlapping state, the gap S is It has extremely good permeability for cleaning liquid, and has good cleaning properties. It is an excellent product that fully achieves reductions in cleaning time, labor costs, and running costs. It has the following effects.
