The utility model technical solution problem, adopts following technical scheme:
The utility model household electric refrigerator condenser, its design feature is: described condenser comprises the condenser leading portion coiled pipe of vertical layout and the condenser back segment coiled pipe of lateral arrangement; Described condenser leading portion coiled pipe and condenser back segment coiled pipe attach respectively in the different side plates that are fixed on refrigerator; Cold-producing medium flows to described condenser back segment coiled pipe through described condenser leading portion coiled pipe;
The utility model household electric refrigerator condenser, its design feature is also: the condenser back segment coiled pipe of described lateral arrangement is arranged horizontally or is angle α with horizontal direction, 90 ° of 0 ° of < α <.
Described condenser leading portion coiled pipe and condenser back segment coiled pipe are integral type setting, and both connect by the condenser jumper pipe that is arranged at refrigerator top board inner side; Or described condenser leading portion coiled pipe and condenser back segment coiled pipe are split type setting, and both weld by tube connector.
The caliber of described condenser leading portion coiled pipe is not less than the caliber of described condenser back segment coiled pipe.
The flow direction of cold-producing medium in described condenser back segment coiled pipe is for from up to down.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model forms condenser by the condenser back segment coiled pipe combination of the condenser leading portion coiled pipe of vertically arranging and lateral arrangement, realize the timely excretion of tube refrigerant film condensation, reduce the condensation hydrops of the U-shaped crook of pipeline, reduce tube refrigerant flow resistance, strengthen the condensation heat transfer process of refrigerant vapour in condenser tube, effectively improved refrigeration performance and the efficiency grade of household electric refrigerator or ice box product;
2, the leading portion pipeline inner refrigerant steam quality of the utility model condenser is large, and flow velocity is high, is designed to vertically " coiled pipe " of layout, is conducive to attenuate refrigerant vapour flow boundary layer, impels fluid each several part fully to mix, enhanced heat exchange effect;
3, in the back segment pipeline of the utility model condenser, point pipeline inner refrigerant steam quality is less, be designed to lateral arrangement (or from the horizontal by certain angle α, 90 ° of 0 ° of < α <, cold-producing medium along gravity direction flow) " coiled pipe ", be conducive to the timely excretion of condensation of refrigerant liquid, the hydrops of having avoided the positions such as the U-shaped bend pipe in vertical tube bottom, has reduced flow resistance, has improved heat transfer intensity;
4, in the utility model, refrigerant fluid flows to the process of condenser back segment coiled pipe of lateral arrangement from the condenser leading portion coiled pipe of vertical layout, refrigerant density progressively increases, flow velocity progressively reduces, become the design of caliber condenser pipe, can effectively reduce flow resistance in pipe, and it is large to bring into play small-pipe diameter heat exchanger effective heat exchange area, the advantage that cold-producing medium flow velocity is fast, boundary layer is thin, improves heat exchange efficiency.
