Compared with the prior art, the utility model the advantage: the adoption has the composite construction's on brazing filler metal layer a heat transfer plate, by the brazing filler metal layer with heat transfer plate and evaporating pipe welding together, the coefficient of heat conductivity of metal brazing filler metal is at 116-237W (m k), the heat conductivility is good for heat transmission effect between evaporating pipe and the heat transfer plate is better, can improve refrigerator refrigerating system's heat exchange efficiency effectively, reduces the refrigerator energy consumption. In addition, its evaporating pipe cross sectional shape is waist type hole, has increased the area of contact of its and heat transfer plate, has further improved heat transfer efficiency.
Description
Technical field
The utility model 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.
Utility model content
The utility model, just in order to avoid the weak point existing for above-mentioned prior art, provides a kind of built-in refrigerator evaporimeter.
The utility model 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, the beneficial effects of the utility model are embodied in:
A kind of built-in refrigerator evaporimeter that the utility model provides, 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.
Accompanying drawing explanation
