The specific embodiment
With the following Examples the utility model is further described.
The specific embodiment of a kind of air-cooled heat-pump air-conditioner heat exchanger of the present utility model, as shown in Figure 1 to Figure 3, comprise heat exchange pipeline, heat exchange fin 2, the isocon 3 being connected with heat exchange pipeline entrance, and the header 4 being connected with heat exchange pipeline outlet, described heat exchange fin 2 offers a plurality of perforation of passing for described heat exchange pipeline 21, described heat exchange pipeline comprises the first row heat exchanger tube 11 sorting successively along airflow direction, second row heat exchanger tube 12 and the 3rd row's heat exchanger tube 13, described heat exchange pipeline entrance is arranged at described the 3rd row's heat exchanger tube 13, described heat exchange pipeline outlet is arranged at described first row heat exchanger tube 11, between the perforation 21 of described heat exchange fin, 2 also offer a plurality of airflow holes 22 for Air Flow.
Described airflow hole 22 is circular airflow hole 22, and described a plurality of airflow holes 22 are matrix arrangements.
In use procedure, during refrigeration, cold-producing medium flows to the 3rd row's heat exchanger tube 13 from first row heat exchanger tube 11, carries out heat exchange successively with air, while heating, and the flow direction of cold-producing medium and process of refrigerastion idea, the opposite direction of refrigerant flow direction and air draught in the course of work.The utility model is because described heat exchange fin 2 also offers the airflow hole 22 for Air Flow, when having foreign matter or foreign material to fall between heat exchange fin 2, air-flow can flow out from foreign matter or the nearest airflow hole 22 of foreign material, thereby avoided the delay of air-flow at foreign matter or foreign material place, thereby effectively guaranteed the heat exchange between air and heat exchange pipeline in air-flow.
Described the 3rd row's heat exchanger tube 13 is linear pattern heat exchanger tube, and described first row heat exchanger tube 11 and described second row heat exchanger tube 12 are L-type heat exchanger tube.Like this, in process of refrigerastion, in process of refrigerastion, when cold-producing medium enters the 3rd row's heat exchanger tube 13, for high-pressure gaseous refrigerant, now cold-producing medium flow velocity is fast, large with Air Temperature Difference, heat exchange is fast, and linear heat exchanger tube is conducive to cold-producing medium Rapid Flow mistake, improves heat exchange efficiency; Cold-producing medium enters after second row heat exchanger tube 12, existing part cold-producing medium enters and is condensed into liquid state, pressure decreased now, flow velocity is slack-off, and second row heat exchanger tube 12 and first row heat exchanger tube 11 are all L-type, this has guaranteed that cold-producing medium is interior mobile at second row heat exchanger tube 12 and first row heat exchanger tube 11, can carry out sufficient heat exchange with air.Heat in process, cold-producing medium first flow through first row heat exchanger tube 11 and second row heat exchanger tube 12, because second row heat exchanger tube 12 and first row heat exchanger tube 11 are L-type, heat exchange is abundant, and temperature is evenly distributed between heat exchanger tube; Cold-producing medium enters after the 3rd row's heat exchanger tube 13, flow process in heat exchanger tube is short, fast with the heat exchange of air, thereby in this process, the condensate water of air is uniformly distributed, each heat exchanger tube periphery of avoiding condensate water to be gathered in the 3rd row's heat exchanger tube 13 forms the moving situation of water film obstruct airflow, is conducive to improve heat exchange efficiency.
In described heat exchange pipeline, the joint 5 that connects two adjacent heat exchange tubes is U-shaped copper pipe joint 5, smooth without sudden change in described joint 5 pipes, has reduced duct pressure loss.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not depart from essence and the scope of technical solutions of the utility model.
