Problems solved by technology

[0002] Most of the existing plate heat exchangers have two types of heat exchange media, and the heat release coefficients of different heat exchange media are different, even very different. The difference in thermal effect is relatively large, but the heat transfer capacity of the plate heat exchanger is often converted based on the medium with a small heat release coefficient. The volume of the device is large, resulting in great waste of materials, high manufacturing cost, and unsatisfactory heat transfer effect

Embodiment Construction

[0007] For a better understanding of the present invention, it will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0008] Such as figure 1 As shown, the plate heat exchanger of the present invention is mainly composed of a shell 1, a plate core 2 placed in the shell, and a medium inlet and outlet arranged on the shell or the core. The plate core 2 is composed of It is assembled by several unit bodies stacked by heat exchange plates 3. The unit body and the unit body and the unit body are all medium circulation channels, and one or more layers of conductive metal plates are installed in the medium circulation channel. 4. There is a support body 5 between the plates of the multi-layer conductive metal plate; the conductive metal plate 4 used can be a flat plate, or a metal corrugated plate with corrugations, which greatly increases the heat exchange of the circulating medium Small area, high heat replacement rate, improved ...

Abstract

The invention relates to a heat exchanger, especially a plate heat exchanger with low cost, easy manufacture and high heat exchange efficiency, which belongs to the technical field of plate heat exchanger design; it includes a shell and a plate core placed in the shell The body and the medium inlet and outlet on the shell or core body, the plate core is assembled by a number of units stacked by heat exchange plates, the unit body and between the unit body and the unit body are all The circulation channel of the medium is characterized in that one or more layers of conductive metal plates are installed in the circulation channel of the medium; in order to increase the heat conduction area and improve the heat exchange efficiency, it has the advantages of reasonable design, compact structure, cost saving, economical and practical.

Description

1. Technical field [0001] The invention relates to a heat exchanger, in particular to a plate heat exchanger with low cost, easy manufacture and high heat exchange efficiency, belonging to the technical field of plate heat exchanger design. 2. Background technology [0002] Most of the existing plate heat exchangers have two types of heat exchange media, and the heat release coefficients of different heat exchange media are different, even very different, and the difference in heat exchange effect is relatively large. The heat is often converted according to the medium with a small heat release coefficient. The overall heat exchange efficiency is low, and the heat exchange unit of the heat exchanger is bound to be increased. The large volume of the heat exchanger results in a great waste of materials and high manufacturing costs. , the heat transfer effect is not ideal. 3. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomi...
