At first, the heat exchanger of circular tube shaped is in being applicable to the refrigerators such as refrigerator the time, and the contact-making surface between pipe and the refrigerator box body is little, and thermograde is little, and thermal resistance is large, causes heat exchange efficiency low.
Secondly, heat exchanger often needs to paste by aluminium foil and is fixed on the refrigerator box body, because circular tube structure is so that circular tube circumference is very large apart from the maximum normal distance of casing, the height that is pipe is larger, reduced that aluminium foil is pasted and casing between contact area, reduce the intensity of pasting of aluminium foil, made heat exchanger easily be separated from aluminium foil, caused the heat exchanger performance fluctuation large.Simultaneously, this structure increased also that aluminium foil is pasted and pipe between air, these air flow property are poor, thermal resistance is large, reduced the heat exchange efficiency of heat exchanger.
The minimizing of the energy requires more and more higher to the efficiency of refrigerator, reducing energy consumption is a main trend of refrigerator development, yet when reducing power consumption, must improve the exchange capability of heat of heat exchanger, but limit by manufacturing cost and small product size, can not strengthen exchange capability of heat by the size of unrestricted increase heat exchanger.Therefore, develop the high heat exchanger of a kind of heat exchange efficiency and have extremely important demonstration meaning.
Summary of the invention
First technical problem to be solved in the utility model provides the high parallel-flow heat exchanger of a kind of heat exchange efficiency.
Second technical problem that the utility model solves provides the high refrigerator of a kind of heat exchange efficiency.
In order to solve first technical problem, the utility model is taked following technological means:
A kind of parallel-flow heat exchanger is comprised of siphunculus, and the two ends of described siphunculus are respectively entrance point and the port of export, it is characterized in that, described entrance point and the port of export are pipe, and the siphunculus between entrance point and the port of export is flat tube, and the ratio L1/W1 of flat tube heat exchange wall width value and flat height is 1～5.

Described parallel-flow heat exchanger is the serpentine coil structure.
Preferably, the maximum gauge H1 of described flat tube is 4 mm～13mm, and the wall thickness S of flat tube is 0.4 mm～1.0mm, and the heat exchange wall width value L1 of described flat tube is 2 mm～10mm, and the flat height W1 of described flat tube is 2 mm～6mm.
Described siphunculus is by copper material or aluminium or steel making.
For solving second technical problem, the technical solution adopted in the utility model is:
A kind of refrigerator comprises refrigeration system, and this refrigeration system comprises compressor, condenser, capillary and the evaporimeter that is communicated with successively by pipeline, it is characterized in that, at least one in described evaporimeter and the condenser is comprised of above-mentioned parallel-flow heat exchanger.
Be communicated with by flat tube between the entrance point of parallel-flow heat exchanger described in the utility model and the port of export, this structure has following beneficial effect:
The first, the utility model is made the flat tube structure with heat exchanger, the ratio of flat tube heat exchange wall width value and flat height is controlled between 1～5, compared with prior art, the tube chamber volumetric ratio circular tube structure of flat tube structure is little, accelerated the flowing velocity of in-tube condensation liquid, simultaneously, the flat tube structure has increased the heat exchange wall area, improved the thermograde of wall, strengthened the uniformity of Temperature Distribution on the cross section, increase substantially the heat exchange efficiency of parallel-flow heat exchanger, reduced the power consumption of the refrigerators such as refrigerator.
The second, parallel-flow heat exchanger uses as evaporimeter and condenser in the refrigerators such as refrigerator usually, evaporimeter and condenser place in the refrigerator casing such as refrigerator and by the heat-barrier material foaming layer and are coated with, the flat tube Structure Decreasing height of prior art pipe, the depth of foam that is coated on the flat tube is increased, reduced evaporimeter heat radiation to external world, strengthen condenser heat transfer to external world, reduced scattering and disappearing of cold, improved capacity usage ratio.
Three, parallel-flow heat exchanger described in the utility model is in the process of using assembling, because the flat height of flat tube reduces, in order to the aluminium foil of stationary heat exchangers paste and the refrigerator casing between paste area change, strengthened the intensity of pasting that aluminium foil pastes, made the parallel-flow heat exchanger more firm.In addition, the flat tube structure reduced also that aluminium foil is pasted and the parallel-flow heat exchanger flat tube between residual air, reduced thermal resistance, further strengthened the heat exchange efficiency of parallel-flow heat exchanger.
Four, the utility model structure and manufacturing process are simple, and low cost of manufacture has good application prospect.
