Together, heat exchange efficiency is improved.And dividing wall type micro heat exchanger has outstanding advantages of size is small, heat transfer coefficient is higher,
Application in small refrigeration systems is more and more common.
A kind of heat exchanger in the prior art being used for Heat Pump as Chinese patent literature CN201974078U discloses one kind
The heat exchanger of condenser, gas cooler or evaporator in hydrophone, electronic equipment dissipating heat, including cold flow plate, heat flux plates and
Side plate.Cold and hot flowing plate is overlapped mutually to form fluid channel, and barrier element is arranged in cold fluid and hot fluid inlet, increases flow resistance,
Fluid is set to distribute more uniform, enhancing heat transfer effect.But this heat exchanger has the disadvantages that：Since the ruler of barrier element is arranged
Very little is the 1/2 of zone of heat liberation cross-sectional area, and the radius in lateral fluid channel is larger, flow is longer, so flow resistance
Still it is more than other runners, barrier element does not solve the problems such as fluid distrbution is uneven very well.
Invention content
The dividing wall type micro heat exchanger processing and manufacturing difficulty for aiming to overcome that the prior art of patent of the present invention greatly, respectively flows
The problems such as road flow resistance difference keeps fluid distribution uneven, provide that a kind of manufacture easy to process, fluid be evenly distributed and heat exchange effect
The higher dividing wall type micro heat exchanger of rate.
In order to solve the above technical problems, the technical solution of patent of the present invention is：A kind of dividing wall type micro heat exchanger, including change
Hot device upper cover plate, heat exchanger lower cover and heat exchanger partition board, heat exchanger upper cover plate have refrigerant to import and export channel, lower edges
Inside has half camber liquid separation slot and remittance liquid bath, and heat exchanger lower cover has refrigerating medium (water) to import and export channel, thereon below
Have half camber liquid separation slot on the inside of edge and converge liquid bath, heat exchanger partition board is provided with heat exchange slit, centre be 1mm thickness heat exchanger every
Plate, refrigerant are fully exchanged heat with refrigerating medium (water) by heat exchanger partition board.The master that heat exchanger plates upper and lower surface is provided with fluid flowing changes
Hot slit and auxiliary bypass slit, the main thoroughfare that main heat exchange slit flows for fluid, and the channel width at fluid inlet
Degree is 0.8mm, and the channel width close to fluid outlet is 1mm, flow when auxiliary heat-exchanging slit flows to balanced fluid
Distribution makes fluid be distributed in heat exchanger more uniformly, enhanced heat exchange effect.
The advantageous effect of patent of the present invention is：
1, simple in structure, convenient processing and manufacture
2, distribution of the fluid in heat exchanger is relatively uniform, good effect of heat exchange.
3, overall volume is small, light weight, compact-sized, is easily applied in small refrigeration systems.

Plate (201) and heat exchanger partition board (301).
Heat exchanger upper cover plate (101) includes refrigerant inlet/outlet pipe (102) (103), is had on the inside of lower edges
Half camber liquid separation slot (104) and the liquid bath (105) that converges, half arc liquid separation slot (104) effectively can uniformly distribute fluid to system
In main heat exchange slit (302) channel of cryogen side, and circular-arc-shaped design can effectively reduce the whirlpool of the generation in process fluid flow
Stream, to reduce fluid-pressure drop.
Heat exchanger lower cover (201) includes refrigerating medium (water) inlet/outlet pipe (202) (203), and lower edges inside is respectively
It is provided with half camber liquid separation slot (204) and remittance liquid bath (205), half arc liquid separation slot (204) effectively can uniformly distribute fluid
Into main heat exchange slit (302) channel of refrigerant side, and circular-arc-shaped design can effectively reduce the generation in process fluid flow
Vortex, to reduce fluid-pressure drop.
Heat exchanger partition board (301) includes main heat exchange slit (302), auxiliary bypass heat exchange slit (303) and floor (304).
