SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a high-efficient heat transfer slab has solved the problem that the heat exchanger slab heat transfer efficiency among the prior art is low.

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

a heat transfer plate of high pressure-bearing capacity 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;

shallow ripples are evenly pressed on the heat transfer area, the shallow ripples are upwards raised, and the height of the raised shallow ripples is 2.5 mm.

Preferably, the flow guide area is provided with flow guide bulges, and a flow guide channel is formed between every two adjacent flow guide bulges.

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 shallow 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 high-efficient heat transfer slab, at first, the suppression has shallow ripple on the heat transfer slab, and the inside runner that is as of shallow ripple, two adjacent heat transfer unit contact through shallow ripple's protruding top promptly protruding top is relative with protruding top, and the recess bottom is relative with the recess bottom, and the point that contacts is as the strong point between the slab, and this kind of structure has both improved the rigidity intensity of slab, can ensure the requirement of fluid to the runner cross-section again.

Additionally, the utility model relates to a suppression has shallow ripple high heat transfer board formula heat exchanger slab, and the ripple degree of depth of shallow ripple is shallow than general ripple degree of depth, about 2.5mm, because the ripple degree of depth is shallow, suppresses relatively easily, and consequently the ripple pitch is less, and the slab thickness is thinner, can obtain very high heat transfer effect, is applicable to very much on average the logarithm difference in temperature and does not exceed 1 ℃'s operating mode, uses very high price/performance ratio at heating, air conditioner and refrigeration trade.

Furthermore, the utility model discloses in the fluid passage that constitutes between the board, covered with the contact point of staggered arrangement, the fluid forms spiral track that gos forward around flowing between these contact points to produce strong disturbance, the shallow ripple has both improved plate heat exchanger's heat transfer efficiency, reduces the heat loss, has strengthened the compressive strength of slab again, and the leakproofness of heat transfer piece has been guaranteed to the seal groove, has improved heat transfer efficiency further.
