Abstract

The utility model discloses a heat exchange plate of a plate-type heat exchanger. The heat exchange plate is provided with a medium inlet and outlet hole, a locating hole, a flow guiding region, a flow shunting region and a heat exchange region, wherein the flow shunting region is triangular and is internally provided with multiple convex points and multiple concave points; when two adjacent heat exchange plates are assembled conversely, the multiple convex points are contacted to form multiple contacts; and medium flow channels are formed among the multiple concave points. As the heat exchange plate of the plate-type heat exchanger is adopted, because the flow shunting region is internally provided with multiple convex points and multiple concave points, and multiple contacts are formed among the convex points after adjacent plates are assembled conversely, the medium can be uniformly distributed to each part of the plate, and the multiple contacts enable the medium to form a strong turbulent flow. Meanwhile, heat transfer is strengthened and pressure bearing capability of the plate is increased.

Description

A kind of heat exchange plate of plate type heat exchanger

Technical field

The utility model relates to a kind of heat exchange plate of plate type heat exchanger.

Background technology

Heat exchange plate is the vitals in the plate type heat exchanger; Heat exchange plate of the prior art all has shunting zone and heat transfer zone; But the design of the shunting zone of most of plate is unreasonable, and liquid distribution is inhomogeneous, causes thermal conductive zone bias current, the uneven phenomenon of heat conduction to occur; Cause heat transfer efficiency to reduce, resistance drop strengthens.

The utility model content

The technical problem that the utility model will solve provide a kind of media flow distributed uniform, heat exchange efficiency high, improve the heat exchange plate of the plate type heat exchanger of plate bearing capacity simultaneously.

For solving the problems of the technologies described above; The heat exchange plate of a kind of plate type heat exchanger of the utility model; On heat exchange plate, be provided with medium import and export, locating hole, water conservancy diversion district, shunting zone and heat transfer zone, this shunting zone be shaped as triangle, be provided with a plurality of salient points and a plurality of concave point in the said shunting zone; Said a plurality of salient points contact and form a plurality of contacts after two adjacent said heat exchange plates are inverted assembling, form medium runner between said a plurality of concave points.

Adopt the heat exchange plate of the plate type heat exchanger of said structure; Owing in shunting zone, be provided with a plurality of salient points and a plurality of concave point; Adjacent plate is inverted the assembling back and between salient point, is formed a plurality of contacts; Make full and uniform each position that is distributed in plate of medium, a plurality of contacts can make medium form strong turbulent flow, simultaneously augmentation of heat transfer and the bearing capacity that increases plate.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done to specify further.

Fig. 1 is the structural representation of the heat exchange plate of a kind of plate type heat exchanger of the utility model.

The specific embodiment

Referring to Fig. 1; The heat exchange plate of a kind of plate type heat exchanger of the utility model; Be provided with on heat exchange plate that medium imports and exports 1, locating hole 2, water conservancy diversion district 3, shunting zone 4 and heat transfer zone (not shown), this shunting zone 4 be shaped as triangle, be provided with a plurality of salient points 5 and a plurality of concave points 6 in the said shunting zone 4; Said a plurality of salient points 5 contact and form a plurality of contacts after two adjacent said heat exchange plates are inverted assembling, and 6 of said a plurality of concave points form medium runner.

Claims
