Abstract

The utility model discloses an arch-type channel heat exchange plate relates to a heat transfer technology. The utility model discloses mainly to extruding many arch type passageways on the metal sheet that the heat conductivility is good, its upper arch face is symmetrical with lower arch face, and the arch face shape can be half pyramid, also can be half pyramid. The utility model discloses can regard as heat transfer medium's passageway, also can regard as convection heat transfer's fin, enlarge heat transfer area, absorb radiant heat high-efficiently.

Description

Arch channel heat exchanging plate

The utility model relates to a kind of thermal conduction study technology, particularly a kind of heat exchanger plates that has arch formula passage.

At present, the type of heat exchanger is many, such as rib-type, plate plumage formula, spiral plate type, board-like, pipe heat exchanger etc., its heat transfer process mainly is to carry out between the different two media of temperature, and the heat conduction of convection current, heat exchange device that utilizes medium is to reach the heat exchange purpose.Different heat exchangers is applicable to different heat transfer boundary conditions, but more than the heat exchange device that exemplifies all can not solve the problem of radiation and convection heat exchange.

The purpose of this utility model provides a kind of arch formula channel for heat exchange plate, and the radiant heat that makes thermal source produce carries out the heat convection of same medium through the arch formula passage on the heat exchanger plates.

The purpose of this utility model is achieved in that

Utilize the ductility of metallic plate, on metallic plate,, make radiant heat that thermal source produces not only by the metallic plate heat radiation to being pressed into various forms of arch formula passages, and main be that air dielectric is taken away a large amount of heats by arch formula passage.

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is the utility model heat exchanger plates schematic diagram.

Accompanying drawing 2 is the utility model arch formula access diagram.

The metal material of heat exchanger plates of the present utility model (1) for having the good heat conductive performance, equably to extruding many arch formula passages (2), the opening direction of these arch formula passages (2) can be according to the specific requirement setting on heat exchanger plates (1).The last arch face (4) and the following arch face (3) of arch formula passage (2) are symmetrical, and the shape of arch can be that semicircle is tapered, can also be half pyramid types.Following arch face (3) and last arch face (4) are formed a complete airflow path, by the air of this passage, can take away the heat on the heat exchanger plates (1), to reach the purpose of heat exchange.

Good effect of the present utility model: 1. the utility model can be used as the passage of medium; 2. the utility model can be used as the fin of heat convection, enlarges heat transfer area; 3. the utility model radiation-absorbing heat expeditiously.

Claims

1, a kind of arch formula channel for heat exchange plate is characterized in that: have on the metal material heat exchanger plates (1) of good heat conductive performance, to extruding many arch formula passages (2), the last arch face (4) and the following arch face (3) of arch formula passage (2) are symmetrical equably.

2, heat exchanger plates according to claim 1 is characterized in that: the type shape of arch face can be that semicircle is tapered, can also be half pyramid type.
