Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-2, the plate heat exchanger includes a fixed clamping plate, a heat transfer plate, a sealing washer, a movable clamping plate, an upper guide rod, a lower guide rod, a column, a clamping bolt and a clamping nut, and further includes a six-V-shaped corrugated high-efficiency heat transfer plate.

The six-V-shaped corrugated efficient heat transfer plate comprises a body, wherein connecting holes 1 are formed in four corners of the body, connecting clamping grooves 2 of a hanging plate are formed in the middle positions of two sides of the body, a heat exchange area 4 is arranged in the middle position of the body, and six-V-shaped corrugations are arranged in the heat exchange area 4.

And two sides of the heat exchange area 4 are provided with shunting areas 3.

The shunting area 3 is provided with shunting grooves.

The surface of the body is provided with supporting salient points.

The length of the body is 2386mm, and the width is 996 mm.

The V-shaped corrugation opening angle of the heat exchange zone 4 is 120 degrees, the opening angle length is 155mm, the interval between every two V-shaped corrugations is 12.05mm, and the depth of the V-shaped corrugations is 3.4 mm.

The corrugated angle of the plate also ranges from 50 degrees to 130 degrees, and the corrugated angle of the plate is selected to be 120 degrees at this time because the heat exchange efficiency is obviously reduced when the corrugated angle is lower than 100 degrees, and the heat exchange efficiency is very high when the corrugated angle is larger than 120 degrees, but the resistance is large;

the heat transfer efficiency of the V-shaped corrugations at different opening angles is shown in the following table:

degree of opening angle	110°	115°	120°	125°
					Efficiency of heat transfer	96%	97%	99%	98%

Therefore, we have chosen 120 ° through experiments under the condition of ensuring the maximum heat exchange efficiency and not influencing the large resistance.

The selection of ripple degree of depth depends on the circulation of the fluid medium of board type self or how big torrent of medium formation in unit interval, the torrent formation rate can improve heat exchange efficiency greatly, board ripple degree of depth usually has between 2mm ~4.2mm, it is different according to the medium content that passes through, the different wave depth of selection of flow is also different, this kind of width 996mm in the design process, the circulation water flow is great when length 2386 mm's big board selection type, if the medium flow is less than when the ripple degree of depth in the 3mm of selection is poor a little, impurity in the liquid also can block up easily, heat transfer effect and bearing capacity descend when being greater than 3.6mm, so will consider to select the ripple degree of depth to be 3.4mm under the condition that does not influence heat transfer efficiency and bearing capacity, can guarantee the circulation of medium like this, the bearing capacity has also been guaranteed.

The plate heat exchanger has the advantages that the heat exchange efficiency is lower when the number of the corrugated V-shaped plates of the plate heat exchanger is smaller, the heat exchange efficiency is higher when the number of the corrugated V-shaped plates of the plate heat exchanger is larger, and one V-shaped plate and two V-shaped plates of the plate heat exchanger are selected to be used, but the heat exchange efficiency of the plate with one V-shaped corrugation is low in the design process, more plates are required to be used under the condition of meeting certain heat exchange efficiency, so that the material and manufacturing cost is increased invisibly for production enterprises, and the market competitiveness is lacked;

then, two V-shaped plates are used, and the practical operation effect shows that the two V-shaped heat exchange effects are better than one V effect.

The comparison of different numbers of V-shaped ripples under the same flow rate is as follows:

through various selective tests, six V-shaped corrugated plates are finally selected, so that turbulence and heat exchange effects can be improved, and the pressure bearing capacity is improved after corrugated contact points are increased due to the large width of the plates; and under the condition that the optimal pressure drop value of the plate heat exchanger is 70Kpa, the maximum heat transfer coefficient of the plate heat exchanger is ensured.

According to the six-V-shaped corrugated efficient heat transfer plate and the plate type heat exchanger, a medium forms large turbulence, dense and hemp structure in unit time, the number of contact points of corrugated contact is large, the heat exchange efficiency is high, the bearing capacity is large, the temperature control is sensitive, the disassembly and assembly are convenient, the contact points between corrugated valleys of the plate in a flow channel are large, the efficiency is ultrahigh, and the like, and the large-scale production is easy to realize.

In summary, the following steps: the plate heat exchanger is composed of a group of heat transfer plates, and four corner holes of the heat transfer plate body are provided with connecting corner holes 1 for two kinds of liquid for heat transfer to pass through. The body is mounted in a frame having a fixed plate and a movable pressure plate on one side and is clamped by a clamping bolt. The body is fitted with a gasket seal to seal the fluid passages and direct the fluid alternately into the respective flow passages to effect counter-current heat exchange.
