The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
The structure of cold, hot two-purpose Evaporative Cooling Air Conditioning heat exchanger of the present invention, as shown in Figure 5, form by the water storage box of heat exchanger core body 7, heat exchanger core body 7 bottoms, the casing that heat exchanger core body 7 relative both sides are provided with.
Heat exchanger core body 7 is arranged side by side and is made up of the heat exchange wall 3 of certain intervals by a plurality of, constitutes passage a1 or passage b2 between adjacent two heat exchange walls 3, and passage a1 and passage b2 are provided with at interval, and the structure of heat exchanger core body 7 is as shown in Figure 1.
What Fig. 2 showed is the structure of single group heat exchanger channels, has been made up of the arrangement of passage b2, passage a1, passage b2 4 heat exchange walls 3.Working media circulates in passage b2, and the output medium circulates in passage a1, and working media and the heat exchange of output medium cross-counterflow have realized the function of air water-wet exchange of air heat and water-hydrothermal exchange.
