Road and extraction channel are tubulose.
Further, the evaporator or condenser also include entering passage spoiler and flow pass spoiler, enter
Passage spoiler is arranged on refrigerant and enters in main channel, and flow pass spoiler is arranged in refrigerant outflow main channel, is entered
Enter passage spoiler and several subchannels are divided into array subchannel by flow pass spoiler, it is logical with introducing into passage spoiler
Several subchannels between road are first group of subchannel, are led into several between passage spoiler and flow pass spoiler
Road is second group of subchannel, and the several subchannels between flow pass spoiler and extraction channel are the 3rd group of subchannel, refrigeration
Agent enters refrigerant and flows out main channel after being entered by introduction passage through first group of subchannel, then enters refrigeration by second group of subchannel
Agent enters in main channel, then is entered in refrigerant outflow main channel by the 3rd group of subchannel, is most flowed out through extraction channel afterwards.
Further, it is plate-fin structure that the main refrigerant flows out main channel into main channel and refrigerant, described
Brazing-sheet type evaporator or condenser also include two waveform shunting fins, and two waveform shunting fins are separately positioned on refrigerant
Into in main channel and refrigerant outflow main channel, waveform shunting fin is connected with front and rear panels brazing mode, the waveform
Shunting fin is wave-shaped fins, and several tap holes, several tap holes are provided with along longitudinal direction in each wavy wall of waveform shunting fin
Aperture gradually increased by refrigerant upstream end or outflow end to its distal end, by refrigerant upstream end or outflow in several tap holes
Hold to two adjacent shunting pitchs of holes of its distal end and be gradually reduced.
Further, the refrigeration plant is refrigerator or refrigerator-freezer.
For brazing-sheet type evaporator or the preparation method of condenser on refrigeration plant, the manufacture craft:Step one,
Punching press is carried out to front and rear panels;
Step 2, front and rear panels are cleaned;

Specific embodiment
Specific embodiment one:Present embodiment is illustrated with reference to Fig. 1 to Fig. 6, present embodiment includes foreboard 1 and back plate 2,
Foreboard 1 is fastened and soldering connection with back plate 2, refrigerant is formed with buckling surface main logical into main channel 1-1, refrigerant outflow
One end of road 1-2 and several subchannel 1-5, each subchannel 1-5 connect with refrigerant into main channel 1-1, each subchannel
The other end of 1-5 is connected with refrigerant outflow main channel 1-2.
By being pressed with intensive, flat small coolant channel on buckling surface, refrigerant area coverage can be made maximum, made
Consumption is minimum, refrigeration, radiating efficiency highest, is connected by brazing mode, two plate faces can be made to form face and contacted, and be gold
Belong to key mode firm connection, it is possible to achieve industrialization, automation the big production of high efficiency, than inflation type, threaded pipe type etc. other
The evaporator of form and the comprehensive advantage of condenser are much higher.
Specific embodiment two:Present embodiment is illustrated with reference to Fig. 1 to Fig. 6, the refrigerant of present embodiment enters main logical
Road 1-1, refrigerant outflow main channel 1-2 and several subchannel 1-5 are in foreboard 1 or back plate 2 in any one piece of plate face
Raised runner.So it is designed as making evaporator or condenser form one side drum runner, it is corresponding another to play drum runner with one side
Block plate body is plane so that this evaporator or condenser are arranged on when on refrigerator or refrigerator-freezer, and plane and refrigerator plastic housing are faces
Contact, and prior art is two-sided drum, two-sided is all linear contact lay, therefore, one side plays drum and compares two-sided bulging effective utilization
Space is big, and increased refrigeration area, shortens the working time of compressor, and refrigeration radiating (heat exchange) speed is fast, efficiency high.Just
For refrigerator, the evaporator of refrigerator-freezer class refrigeration plant, the evaporator that one side plays drum runner is conducive to its surface plate and refrigeration plant
Plastic casing formed face contact, make refrigerating speed faster, it is in hgher efficiency, therefore the working time of compressor can also shorten a lot,
Energy consumption drop is a lot, and with thinning insulation layer thickness, can reduce the useful space utilization rate of box volume or increase casing, also saves
About insulation material and metal material.If two-sided drum of inflation type, coiled, then it is that line connects to play drum surface with plastic casing
Touch, its refrigerating speed and efficiency are much lower, and to increase insulation layer thickness, increase box volume, waste a large amount of thermal insulating materials
Material, metal material and electric energy.For refrigerator, the condenser of refrigerator-freezer class refrigeration plant, drum condenser is played with the one side of this patent,
The interior viscous formula or external hanging type condenser for using currently on the market can be substituted, and shell plates can be also served as with condenser plate, saved
