Problems solved by technology

The waste heat recovery device in the prior art is composed of multiple plates connected together by screws or other means. The waste heat recovery device of this structure has a single soft corrugation or a single hard corrugation, which cannot be well considered. Heat transfer and pressure, and for side feeding, the distribution uniformity of the medium is poor, and dead zones are prone to occur

Embodiment Construction

[0007] The present invention will be further described below in conjunction with accompanying drawing.

[0008] In order to solve the above technical problems, a plate for a waste heat recovery device was invented, including a plate body 1, the plate body 1 is divided into a distribution area 3 and a heat transfer area 4, and the distribution area 3 and the heat transfer area 4 are respectively Corrugations 2 are provided, and the corrugations 2 include a first group of corrugations 2-1 distributed in the distribution area 3 at both ends of the plate body 1 and a second group of corrugations 2-2 distributed in the heat transfer area 4 of the plate body 1, wherein the The distances t1, t2, t3 and t4 between adjacent corrugations of the corrugations 2-2 in the heat transfer zone 4 are arranged in descending order. Since the distances between the corrugations 2-2 of the heat transfer zone 4 are arranged in order from small to large, after the medium enters the heat transfer zone,...

Abstract

The invention provides a plate sheet used for a waste heat recycling device. The plate sheet comprises a plate body, wherein the plate body is divided into a distribution area and a heat transmission area; the distribution area and the heat transmission area are respectively provided with ripples; the ripples comprise a first group of ripples which are distributed at the distribution areas at two ends of the plate body and a second group of ripples distributed at the heat transmission area of the plate body; wherein the distances t1, t2, t3 and t4 between adjacent ripples of the second group of ripples at the heat transmission area are arranged from small to large in sequence. As the distances between adjacent ripples of the second group of ripples at the heat transmission area are arranged from small to large in sequence, mediums flow through the ripples after entering the heat transmission area and flow through the distances from small to large, the pressure of the mediums is released gradually, the pressure that a corrugated plate bears is reduced, so that the bearing ability of the corrugated plate is increased greatly.

Description

technical field [0001] The invention relates to a waste heat recovery device, in particular to a plate used for the waste heat recovery device, and belongs to the technical field of heat exchange equipment. Background technique [0002] The waste heat recovery device is a device that recovers and utilizes heat through heat exchange. With the development of society, in order to save energy, waste heat recovery devices are used more and more widely. A traditional waste heat recovery device includes a shell and a waste heat recovery device; the shell is provided with an inlet and an outlet, and the waste heat recovery device is installed in the shell through fasteners; the waste heat recovery device is a key component in the waste heat recovery device . The waste heat recovery device in the prior art is composed of multiple plates connected together by screws or other means. The waste heat recovery device of this structure has a single soft corrugation or a single hard corrug...
