Along with the rapid development of economy in China and the continuous improvement of the requirements of people on the environmental quality, under the new situation that people pay more attention to and pursue safety, stability and high efficiency, the development of urban centralized heating is more and more generally concerned by people, the market scale of the urban centralized heating industry in China is continuously enlarged, so that the plate heat exchanger has higher requirements on the pressure bearing capacity, the condition that the plate heat exchanger in the prior art is low in pressure bearing capacity cannot meet the requirements of the development of the centralized heating industry, and therefore, how to research out the heat transfer plate with high pressure bearing capacity is a problem that technical personnel in the field need to solve urgently.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a 0.85 square meter high pressure-bearing capacity's heat transfer slab has solved the poor pressure-bearing capacity of heat transfer slab among the prior art, the problem of inefficiency.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a heat transfer plate having a high pressure bearing capacity of 0.85 square meter, comprising: the plate comprises a plate body, an angle hole, a sealing gasket, a sealing groove, a heat transfer area and a flow guide area;

the four corners of the plate body are respectively provided with the corner holes, the sealing gasket is mounted in the sealing groove at the periphery of the plate, the heat transfer area is arranged in the middle of the plate body, and the flow guide areas are arranged at the two ends of the heat transfer area;

the flow guide areas are provided with flow guide bulges, and flow guide is formed between every two adjacent flow guide bulges.

Preferably, herringbone corrugations are evenly pressed on the heat transfer area, and the herringbone corrugations are convex upwards.

Preferably, two of the plate bodies are assembled into one heat transfer unit.

Preferably, two of said sheet bodies form uniformly staggered contact points therebetween.

Preferably, two adjacent heat transfer units are in contact through the convex tips of the herringbone corrugations.

Preferably, the plate further comprises positioning holes which are respectively arranged at the top end and the bottom end of the plate body.

According to the technical scheme, compare with prior art, the utility model discloses a 0.85 high pressure-bearing capacity's of square meter heat transfer slab has the chevron shape ripple to be suppressed on the heat transfer slab, the convex-concave cross-section in the chevron shape ripple is as the runner, two adjacent heat transfer units contact through the bellied top of chevron shape ripple promptly protruding top is relative with protruding top, the recess bottom is relative with the recess bottom, the point that contacts is as the strong point between the slab, this kind of structure has both improved the rigidity intensity of slab, can ensure the requirement of fluid to the runner cross-section again. In the fluid passage that constitutes between the board, distributed the contact point of staggered, the fluid forms spiral track that gos forward around flowing between these contact points to produce strong disturbance, adopt many people word line form, but also be provided with seal groove and seal gasket and both improved plate heat exchanger's heat transfer efficiency, reduce the heat loss, strengthened the compressive strength of slab again, consequently the utility model discloses can improve plate heat exchanger pressure-resistant ability, application scope is more extensive.
