The evaporation pipes and the heat transfer plate are connected into a whole and then attached to the outer surface of a box container of a refrigerator to form a refrigeration layer. The heat transfer plate is of a composite structure and is formed by sequentially connecting a brazing filler metal layer, a base layer and a pressure-sensitive adhesive layer. The heat transfer plate and the evaporation pipes are welded together through the brazing filler metal layer. The heat transfer plate and the box container of the refrigerator are attached together through the pressure-sensitive adhesive layer. Compared with the prior art, the built-in type refrigerator evaporator has the technical beneficial effects that the heat transfer plate which is provided with the brazing filler metal layer and of the composite structure is adopted, and the heat transfer plate and the evaporation pipes are welded together through the brazing filler metal layer; the heat transfer coefficient of brazing filler metal ranges from 116 W/(m k) to 237 W/(m k), the heat conduction performance is good, and therefore the heat transfer effect between the evaporation pipes and the heat transfer plate is better; the heat exchange efficiency of a refrigeration system of the refrigerator can be effectively improved; and the energy consumption of the refrigerator can be effectively improved. In addition, the sections of the evaporation pipes are each shaped like a kidney-shaped hole, the contact area between the evaporation pipes and the heat transfer plate is enlarged, and the heat transfer efficiency is further improved.
Description
Technical field
The present invention relates to technical field of refrigeration equipment, in particular a kind of built-in refrigerator evaporimeter.
Background technology
The heat exchanger of refrigerator comprises evaporimeter and condenser, and the heat exchange efficiency improving heat exchanger is the effective means improving refrigerator refrigeration system efficiency, reduce energy consumption.
The evaporimeter of refrigerator has two types, and a kind of evaporimeter is located between heat-insulation layer and liner, is called built-in evaporimeter, and its advantage is that refrigerator space utilization rate is high.The design of traditional built-in evaporimeter adopts the mode of PUR or setting-in evaporation tube and heat transfer plate to be fixed together.The thermal conductivity factor of PUR is at 0.32 ~ 2.3W/ (mk), and heat conductivility is poor.And the fixed form of setting-in exists air-gap, the very little 0.023W/ (mk) of thermal conductivity factor of air, for the air-gap reducing embedding structure is very high to the requirement of processing technology.
Summary of the invention
The present invention, just in order to avoid the weak point existing for above-mentioned prior art, provides a kind of built-in refrigerator evaporimeter.
The present invention is that technical solution problem adopts following technical scheme:
A kind of built-in refrigerator evaporimeter, comprise evaporation tube and heat transfer plate, the case courage outer surface being mounted on refrigerator after described evaporation tube and heat transfer plate are connected as a single entity forms refrigerating layer, described heat transfer plate is composite construction, described heat transfer plate is made up of the solder layer connected successively, basic unit and pressure-sensitive adhesive layer, described heat transfer plate is welded together by solder layer and described evaporation tube, and described heat transfer plate is adhered together by the case courage of pressure-sensitive adhesive layer and described refrigerator.
Described evaporation tube outer surface is provided with one deck solder film, and described evaporation tube is welded together by described solder film and described heat transfer plate.
The cross sectional shape of described evaporation tube is flat-shaped waist-shaped hole, and the straightway of described waist-shaped hole contacts with described heat transfer plate.
Compared with the prior art, beneficial effect of the present invention is embodied in:
A kind of built-in refrigerator evaporimeter provided by the invention, adopt the heat transfer plate with the composite construction of solder layer, by solder layer, heat transfer plate and evaporation tube are welded together, the thermal conductivity factor of metal solder is at 116 ~ 237W/ (mk), good heat conductivity, make the heat-transfer effect between evaporation tube and heat transfer plate better, effectively can improve the heat exchange efficiency of refrigerator refrigeration system, reduce energy consumption of refrigerator.In addition, its evaporation tube cross sectional shape is waist-shaped hole, adds the contact area of itself and heat transfer plate, further increases heat transfer efficiency.
