Refrigerator evaporator with efficient temperature changing chamber

Abstract

The invention discloses a refrigerator evaporator with an efficient temperature changing chamber. The refrigerator evaporator comprises a refrigerating chamber evaporator, a temperature changing chamber evaporator, a capillary tube and a transition tube. The refrigerating chamber evaporator comprises a refrigerating chamber aluminum plate and a refrigerating chamber heat exchanging tube. The refrigerating chamber heat exchanging tube is fixed to the refrigerating chamber aluminum plate after being folded in a multi-round mode. The temperature changing chamber evaporator comprises a temperature changing chamber aluminum plate and a temperature changing chamber heat exchanging tube, and the temperature changing chamber heat exchanging tube is fixed to the temperature changing chamber aluminum plate after being folded in a multi-round mode. One end of the refrigerating chamber heat exchanging tube and one end of the temperature changing chamber heat exchanging tube are connected together. One end of the capillary tube is inserted in the end of the transition tube and is in sealing connection with the end of the transition tube. The folded end of the temperature changing chamber heat exchanging tube is of a structure in the shape like Arabic number 9. The refrigerator evaporator is characterized in that the temperature changing chamber aluminum plate is provided with a groove corresponding to the temperature changing chamber heat exchanging tube, and the temperature changing chamber heat exchanging tube is embedded in the groove of the temperature changing chamber aluminum plate; the tube wall of the end, connected with the capillary tube, of the transition tube protrudes outwards to form an extruding hoop. The temperature changing chamber evaporator is high in heat exchanging efficiency and good in temperature changing effect.

Description

technical field [0001] The invention relates to an evaporator, in particular to a refrigerator evaporator. Background technique [0002] In order to increase the use function of the refrigerator, some refrigerator refrigerated evaporators have added variable room evaporators. The variable room evaporators of this type of refrigerator refrigerated evaporator include variable room aluminum plates, variable room heat exchange tubes, and variable room heat exchange tubes. After being bent, it is fixed on the aluminum plate of the variable room. The bent end of the heat exchange tube of the variable room is U-shaped. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the utility model proposes a refrigerator evaporator equipped with a high-efficiency variable-temperature greenhouse, which can significantly improve the heat exchange efficiency of the variable-temperature greenhouse evaporator. [0004] The present invention achieves technical goals ...
