Description

Reinforcing plate of plate heat exchanger

Technical Field

The utility model relates to a plate heat exchanger reinforcing plate field especially relates to a plate heat exchanger reinforcing plate.

Background

The plate heat exchanger is a new type high-efficiency heat exchanger formed by stacking a series of metal sheets with certain corrugated shapes. Thin rectangular channels are formed between the various plates through which heat is exchanged. The plate heat exchanger is an ideal device for heat exchange of liquid-liquid and liquid-vapor. The heat exchanger has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small occupied area, convenience in installation and cleaning, wide application, long service life and the like.

All heat transfer areas of the traditional plate heat exchanger flow distribution area can not fully and uniformly participate in high-efficiency heat transfer, the internal circulation aperture is small, the cross section of an internal channel is reduced or even blocked after scaling, the heat exchange efficiency of the plate heat exchanger is reduced, the phenomenon of chloride ion corrosion occurs, and the normal operation of production and the safety of equipment are influenced.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned defect of prior art, the utility model provides a plate heat exchanger reinforcing plate, including reinforcing plate body 1, seal groove 2 has been seted up along the periphery to 1 upper surface of reinforcing plate body, through-hole 3 has all been seted up in 1 four corners department of reinforcing plate body, through-hole 3 all is located 2 four corners inboards of seal groove, ripple 4 has been seted up along center department in 1 upper surface of reinforcing plate body, ripple 4 array distribution has a plurality ofly, and ripple 4 is "people" word column structure.

Preferably, the key grooves 5 are formed in the upper end and the lower end of the reinforcing plate body 1 along the central line.

Preferably, the key slot 5 is of T-shaped configuration.

Preferably, a sealing strip 6 is mounted on the sealing groove 2.

Preferably, the upper surface of the reinforcing plate body 1 is also provided with a spare branch 7.

Preferably, the reserve flow 7 is arranged along the through-hole 3 at a linear distance from the corrugation 4.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in fig. 1-3, the present invention comprises: reinforcing plate body 1, sealing groove 2 has been seted up along the periphery to reinforcing plate body 1 upper surface, through-hole 3 has all been seted up in 1 four corners department of reinforcing plate body, through-hole 3 all is located 2 four corners inboards in sealing groove, ripple 4 has been seted up along center department in 1 upper surface of reinforcing plate body, ripple 4 array distribution has a plurality ofly, and ripple 4 is "people" word column structure.

In this embodiment, it is preferable that the reinforcing plate body 1 has key grooves 5 formed at both upper and lower ends thereof along a center line.

In this embodiment, the key slot 5 is preferably of T-shaped configuration.

In this embodiment, a seal 6 is preferably attached to the seal groove 2.

The structure prevents the fluid from leaking, and seals a part of the corner holes at the same time, so that the two fluids alternately flow at the two sides of the thin plate for heat exchange.

In this embodiment, the upper surface of the reinforcing plate body 1 is preferably further opened with a backup branch 7.

In the present embodiment, the back-up branch 7 is preferably arranged along the straight-line distance from the through-opening 3 to the corrugation 4.

In this embodiment, it is preferable that the upper surface and the lower surface of the reinforcing plate body 1 have the same structure.

In use, when fluid passes through the corrugations on the reinforcing plate body, the fluid is prevented from forming strong turbulence, and the turbulence not only improves the speed of heat conduction but also prevents sediment from accumulating on the plate surface;

the design of the corrugated herringbone structure enables the plate to be thinner, strengthens heat conduction force, provides mechanical strength and improves the pressure bearing capacity of the heat exchanger. The uneven ripples enable liquid to be in a turbulent flow state, the turbulent flow not only improves the heat conduction speed, but also can reduce the formation of sediments and play a role in keeping clean.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
