Abstract

The utility model relates to a heat-transfer plate for a plate type heat exchanger. The surface of the utility model is distributed with ripples which are shaped by pressing, each complete ripple is a special-shaped W stripe which is composed of two inclined Y-shaped stripes with the same shape and size; the plate is provided with through holes used for difference fluids to flow through. The heat exchanger which is assembled by the utility model can have six kinds of combination channel modes so that the application of the plate type heat exchanger has more selections, and the design is optimized in a greater degree.

Description

A kind of novel heat transferring plate

The utility model belongs to the heat-exchange apparatus field, particularly a kind of heat transferring plate that is used for plate type heat exchanger.

The heat transferring plate of initial stage plate type heat exchanger is the channel floor of the system of milling, and has occurred multi-form corrugated cardboard sheets such as the straight ripple of level, stairstepping ripple, herringbone ripple afterwards in succession.In these ripple patterns, use comparatively universal with the herringbone ripple at present.This is because V-shape corrugated plate has heat transfer coefficient height, advantage that bearing capacity is strong.According to the size of chevron herringbone angle θ, can be divided into high θ angle (θ is the obtuse angle) and low θ angle (θ is an acute angle) plate to the chevron plate, be hardboard sheet (H plate) and soft board sheet (L plate) again respectively.Two-phase neighbour's font corrugated cardboard sheet is inverted (promptly with 180 ° relatively) combination mutually, makes between plate passage can form HH passage (being made up of the H plate), LL passage, HL passage.The passage of plate type heat exchanger can be made of single passage (promptly all being HH passage or LL passage or HL passage), also can be made of hybrid channel (as the mixing of modes such as HH and HL or HL and LL).Adopt the hybrid channel more can make the design of plate type heat exchanger reach optimization.But because two mutual inversions of V-shape corrugated plate can only be combined into 3 kinds of passages, so the optimal design of plate type heat exchanger is restricted.For example, if the flow difference of the two kinds of fluids in plate both sides, promptly so-called asymmetric fluid, then the plate type heat exchanger of combinations thereof can not address this problem rightly, thereby heat exchanger area is increased, and produces unnecessary waste.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of novel heat exchange plate is provided, and makes the application of plate type heat exchanger that more selection be arranged, and design is optimized more.

The utility model is realized in the following manner:

A kind of novel heat transferring plate, the surface is furnished with the ripple of press forming, and heat transfer plate is provided with the through hole that is used for the different fluid percolation, and every complete ripple is the special-shaped W line for being formed by connecting by two shapes, the identical oblique chevron of size all, when its herringbone angle θ is the obtuse angle, be high θ plate (H plate); During for acute angle and right angle, be low θ plate (L plate); This heat transferring plate is that the boundary is divided into upper and lower two and half districts with the center, the special-shaped W ripple incline direction difference in two and half districts, if the special-shaped W ripple in half district tilts to left down, then the special-shaped W ripple in second half district has a down dip to the right.

The ripple of this heat transferring plate is owing to adopt special-shaped W line, thereby can provide 6 kinds of combination passages, and this makes the application of plate type heat exchanger that more selection arranged, and its design can be optimized better.

This heat transferring plate can be made by materials such as the corrosion resistant plate of all size, copper coin, aluminium sheet, steel plate, titanium plates.

Description of drawings:

Fig. 1 is the structural representation of the utility model (H plate).

Fig. 2 is the structural representation of the utility model (L plate).

Fig. 3 is the utility model HH ₁Combination passage pattern.

1 is the special-shaped W ripple that tilts to left down among the figure; 2 is the special-shaped W ripple that has a down dip to the right; 3 is through hole;

Below in conjunction with accompanying drawing, provide a most preferred embodiment of the present utility model.

Be illustrated in figure 3 as a kind of combination passage embodiment of the present invention, be HH ₁Passage, promptly ripple herringbone angle θ is 120 ° the mutual inverted homonymy combination of two adjacent plates; The utility model also can be combined to HH ₂Passage, promptly ripple herringbone angle θ is the mutual inverted heteropleural of two adjacent plates (being one of them the plate counter-rotating) combination at obtuse angle; LL ₁Passage, promptly ripple herringbone angle θ is the mutual inverted homonymy combination of two adjacent plates of acute angle; LL ₂Passage, promptly ripple herringbone angle θ is the mutual inverted heteropleural combination of two adjacent plates of acute angle; LL ₁Passage, promptly one of ripple herringbone angle θ is the mutual inverted homonymy combination of obtuse angle, another two adjacent plates for acute angle; HL ₂Passage, promptly one of ripple herringbone angle θ is the mutual inverted heteropleural combination of obtuse angle, another two adjacent plates for acute angle.

Can optimize the plate type heat exchanger of forming with welding, soldering, bonding, riveted joint or similar approach assembling by above-mentioned six kinds of combination passages.
