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 the flow 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.
