The specific embodiment

Core of the present utility model is to provide a kind of A/C evaporator, comprise long U pipe and fin, the long axis direction of long U pipe is identical with the air flow direction that enters evaporimeter, air stream is after entering evaporimeter, cross section due to long U pipe is oval simultaneously, increase space, be conducive to air by evaporimeter, reduce resistance.

Fin is fenestration, and the direction of windowing of fin is identical with the long axis direction of long U pipe, can reduce better the windage of the air stream that enters evaporimeter, increases air circulation, strengthens evaporimeter exchange capability of heat, promotes air conditioner efficiency and reduces energy consumption.

In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment

Please refer to Fig. 1, the utility model is the A/C evaporator of console mode, air stream enters from air conditioner 104 belows, along with the direction of arrow is mobile, structural limitations due to Floot type air conditioner, evaporimeter 101 slant settings are in air conditioner 104, and the angle of the horizontal plane that evaporimeter 101 is placed and the horizontal plane at air conditioner 104 places is less.

The cross section of long U pipe 102 is oval, is conducive to reduce windward side, increases air circulation.Long U pipe is heat exchanger tube, and the long axis direction (not shown in the diagram) of long U pipe 102 is identical with the air flow direction that enters evaporimeter 101, is conducive to like this reduce windage, increase Air-conditioning Cycle air quantity, increase air outlet pressure reduction, making to farther distance air-supply, to increase the efficiency of air conditioner.

Fin 103 is fenestration, and the direction of windowing of fin 103 is identical with the long axis direction of described long U pipe 102, and air stream can directly pass through fin 103, reduces gas flow resistance.

The plane at long U Guan102 place becomes angle α with the plane at evaporimeter 101 windward side places, the plane at the direction place of windowing of fin 103 becomes angle α with the plane at evaporimeter 101 windward side places, the size of angle α is 10 °～14 °, the size of angle α is consistent with the angle of the plane at evaporimeter 101 places and the plane at air conditioner 104 places, therefore air stream can more directly enter evaporimeter 101, reduces windage.
