Through the mutual stack of heat transfer board, just can form the heat transfer device of arbitrary thickness, can require to adjust according to required heat transfer, and every layer of heat transfer board is through design guide heat transfer groove, netted heat transfer groove and wave heat transfer groove can make cooling water and refrigerated water can the intensive mixing, wherein, guide heat transfer groove is in order to make the cooling water/refrigerated water of heat transfer mouth department can enter into the route of the netted heat transfer groove of intercommunication as early as possible, then can make cooling water/refrigerated water form bigger and the area of contact of heat transfer surface dispel the heat at netted heat transfer groove, can get into more wave heat transfer groove passageways simultaneously, and can mix the cooling water and the refrigerated water that come wave heat transfer groove through the intercommunication heat transfer groove, because wave heat transfer groove is in large quantity, can produce mixing many times, make the mixed effect more.

Simultaneously, because the import of frozen water and import and cooling water is in the same one side of heat transfer board length direction, all frozen water and cooling water if need leave, just must pass through heat transfer mouth, guide heat transfer groove and be connected to the passageway, netted heat transfer groove, wave heat transfer groove and the intercommunication heat transfer groove in netted heat transfer groove for the distance of heat transfer is elongated, has prolonged the distance of heat transfer and also represents and to have more sufficient time to carry out the heat transfer, makes the heat transfer effect promote.

Further, if the heat exchange distance is long, the heat exchange effect is affected, which is impossible, because the number of the heat exchange plates can be increased to increase the amount of heat exchange per time.

Furthermore, raised planes are formed at the channel intervals of the guide heat exchange grooves and the reticular heat exchange grooves, and a plurality of concave grooves are arranged on the raised planes.

And partial overflow or a channel which is not tightly combined and can be accessed is provided, so that the superposed heat exchange plates can be attached as much as possible.

Furthermore, the front surface of one of the heat exchange plates is superposed on the back surface of the other heat exchange plate, and all heat exchange ports of the heat exchange plate positioned at the bottom are closed.

Forming a closed loop.

Further, the front and back surfaces of all the heat exchange plates are coated with aluminum heat exchange layers.

The heat dissipation and heat exchange effects are improved.

Further, the wave heat exchange groove continuously undulates along the width direction of the heat exchange plate.

So that the heat exchange distance is prolonged.

Further, the heat exchange port, the guide heat exchange groove, the passage for connecting the guide heat exchange groove to the net-shaped heat exchange groove, the wave heat exchange groove and the communication heat exchange groove form a passage.

Has the advantages that: compared with the prior art, the utility model has the following advantages:

and a longer heat exchange distance is adopted, so that the heat exchange effect is better.

Through the stack of multilayer heat transfer board, can adjust according to the operating mode of difference for heat transfer device can adapt to more heat transfer demands.
