Abstract

The utility model provides a heat exchanger plate for plate heat exchangers, wherein section of the plate heat transfer area is in a sine wave form, the sine wave is arranged in a herringbone type, horizontal type, vertical type or inclined type. The plate has strong bearing ability, no deformation, uniform fluid distribution, low pressure loss and reduced flow dead area, and can improve heat exchange efficiency and prolong service life. Under same heat exchange area, the heat exchange plate can save the consumption of metals. The heat exchanger plate has the advantages of simple structure, simple production, reliable performance, long service and wide application.

Description

A kind of heat exchanger plate

Technical field:

The utility model relates to the heat transfer element in the heat-exchange apparatus, particularly relates to the heat transfer element in a kind of plate type heat exchanger.

Background technology:

Plate type heat exchanger is to be the high-efficiency heat exchanger equipment of heat transfer element with the metal corrugated plate, and it is triangle that the ripple of its heat transferring plate generally adopts the cross section.Though this heat transferring plate manufacture craft is simple, heat transfer efficiency is low, and metal material consumption is big.

Summary of the invention:

The purpose of this utility model is for a kind of heat exchanger plate is provided, and mainly is that the heat transfer efficiency of the existing plate type heat exchanger metal corrugated plate existence of solution is low, the problem that metal material consumption is big.

The technical solution of the utility model is as described below: this utility model comprises locating hole, medium import and export, water conservancy diversion district, shunting zone, it be heat transfer zone to be set to the cross section be sinusoidal waveform, and should sine wave be herringbone or level vertically or oblique arrangement form.

The beneficial effect that this reality is novel: because this plate has been taked described waveform, make expansion coefficient reach 1.42, can improve heat transfer area 20%, so just can improve heat exchange efficiency.Simultaneously because the contact between plate is the face contact, it is strong, not yielding therefore to have a bearing capacity, even fluid distribution, and the pressure loss is little, reduces flow dead, the characteristics that effectively increase the service life.And under identical heat exchange area situation, save the consumption of metal material.Also have advantages such as simple in structure, easy to make, dependable performance, strong, the suitable popularization of durability.
