Description

Improved plate type heat exchanger

Technical Field

The utility model relates to a plate heat exchanger especially relates to a novel in design, can further improve heat exchange efficiency's improvement plate heat exchanger.

Background

The plate heat exchanger is a commonly used dividing wall type heat exchanger and has the characteristics of high heat transfer efficiency, small resistance loss, compact structure, convenience in assembly and disassembly, long service life and the like. The plate heat exchanger is formed by a plurality of pressed corrugated metal sheets at certain intervals, the peripheries of the pressed corrugated metal sheets are sealed by gaskets and are compressed by a frame and a clamping bolt pair, four corner holes of the plate sheets and the gaskets form a fluid distribution pipe and a fluid collection pipe, simultaneously, cold and hot fluids are reasonably and freely guided and distributed, and the purpose of heat exchange is achieved by heat transfer through the plate sheets. The basic elements of the plate heat exchanger are formed, wherein the plate sheets are heat transfer elements and determine the heat transfer rate, resistance loss, pressure bearing capacity, applicable fluid, service life and the like of the plate heat exchanger; the gasket determines the pressure-bearing capacity, the applicable fluid, the maintenance period and the like of the plate heat exchanger.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides an improve plate heat exchanger, it has unique fluid passage design, and it is convenient to make and load and unload, can improve fluid distribution speed, further improves heat exchange efficiency.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

an improved plate heat exchanger is characterized in that: including a plurality of heat exchanger pieces, the surface of heat exchanger piece is equipped with corrugated structure's heat transfer passageway, is equipped with first liquid inlet, second fluid inlet, first fluid liquid outlet and the second fluid liquid outlet that the diameter is unequal on the heat exchanger piece corresponds the position, and after the heat exchanger piece closed assembly, first fluid inlet constitutes first inlet channel, first fluid inlet constitutes second inlet channel, second fluid liquid outlet constitutes first liquid outlet channel, second fluid liquid outlet constitutes second liquid outlet channel, first inlet channel, second inlet channel, first liquid outlet channel and second liquid outlet channel are venturi structure on the horizontal transmission direction.

Preferably, the first fluid inlet and the second fluid inlet are both provided with distribution holes for distributing fluid to the outside.

Due to the adoption of the technical scheme, the utility model discloses following technological effect has: the utility model discloses have unique fluid passage design, it is convenient to make and load and unload, can improve fluid distribution speed, further improves heat exchange efficiency.
