Abstract

The invention discloses a condenser which is composed of a porous micro through heat exchange flat tube, a corresponding connecting header and a heat dissipation back plate arranged at one side of the heat exchange flat tube. In the invention, the structure is compact, the heat exchange efficiency is high, the aluminum flat tube is adopted, thus the condenser is more advantageous than the existing copper heat exchange tube in the aspect of economical efficiency, and the condenser is suitable for the fields such as refrigeration, chemical engineering, energy source, heat exchange and the like.The condenser is characterized in that on the one hand, since the porous micro channel flat tube structure is adopted, the coefficient of heat transfer in the tube is improved, and simultaneously theflow resistance of a refrigerant in the tube is reduced; and on the other hand, the contact type of the condenser and the side wall of the heat dissipation back plate is surface contact, so that contact thermal resistance is reduced, the average temperature of the side wall of the heat dissipation back plate is improved, and the heat exchange between the side wall of the back plate and the ambient air is strengthened, namely the condensing effect is strengthened, thus, when the lengths of pipes are the same, the quantity of the condenser can be increased, or when the heat exchange quantities are the same, the length of the pipes can be reduced, therefore the condenser is more compact, simultaneously the material consumption is reduced, and the condenser has a certain advantage in the aspect of economical efficiency.

Description

technical field

[0001] The invention belongs to the field of general household refrigeration, and in particular relates to a built-in condenser suitable for refrigeration equipment such as general refrigerators or freezers. Background technique

[0002] Refrigerators and freezers are the only household electrical appliances that consume electricity throughout the day. While bringing people a comfortable life, they also consume a lot of electricity. The promulgation of my country's "Restricted Values ​​of Power Consumption and Energy Efficiency Levels of Household Refrigerators (GB12021.2-2008)" has mandated technological transformation and innovation on refrigerators, hoping to save more energy. From the point of view of the refrigeration system, the condenser undertakes the task of radiating heat outward, and its heat load is the largest, so it is one of the main components that need to be strengthened in energy-saving research. Existing refrigerator condensers are mainly ...
