To the wing piece structure of heat exchanger tubal form undertook optimizing design and be improvemented, adopt TESCOR platform, stage of experiment of heat exchanger function checks to improving the heating power function of the heat exchanger of around to undertake. Put forward aggrandizement wing piece two kinds of methods of function of heat exchange of heat exchanger tubal form: Chaos of You of た of deer of buttock of of extensive qualitative wall catchs locust of sprain act to circle? evaporator) wing piece the canal is designed change span wing piece structure, make its added the wing inside the canal already piece conduct heat area, the; of velocity of flow that increased the air current inside the canal again is the heat exchanger that leaves air conditioning operating mode another kind wait for the whorl inside pitch to be in charge of a design to become change canal of the whorl inside pitch, in order to increase the air current inside the canal disturb, rise conduct heat coefficient. The heating power function of the heat exchanger after be being improved to using these two kinds of methods had consideration, the result makes clear, its conduct heat coefficient raised 9 8% and 3 82% respectively. Current, domestic and international the commonnest and application is the widest is next door type, the design of other type heat exchanger and computation often are drawn lessons from at heat exchanger of next door type. To heat exchanger study how main concentration is improving performance of its heat exchange. The author in article put forward aggrandizement wing piece the method of function of heat exchange of heat exchanger tubal form, to the wing piece structure of heat exchanger tubal form undertook optimizing design and be improvemented. Adopt TESCOR platform, stage of experiment of heat exchanger function, had a test to improving the heating power performance of the heat exchanger of around, and service test data undertook to its heating power contrast is calculated.
