Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the agent structure schematic diagram of the isolated counter-flow air heat-exchanger rig of air-out down provided by the utility model.
The specific embodiment
As shown in Figure 1, the agent structure of air heat-exchanging device provided by the utility model is made up of heat exchange core body, two current dividers (i.e. first current divider and second current divider), two blower fans (i.e. first blower fan and second blower fan), four air ports.Four air ports are respectively indoor air inlet A, indoor air outlet B, outdoor air inlet C and outdoor air outlet D.
In this air heat-exchanging device, form first air channel by indoor air inlet A, first current divider, heat exchange core body, second current divider and indoor air outlet B, the air-flow in this air channel of flowing through is defined as air-flow I; Form second air channel by outdoor air inlet C, second current divider, heat exchange core body, first current divider and outdoor air outlet D, the air-flow in this air channel of flowing through is defined as air-flow II.Be that metal heat-conducting is every wind body, i.e. heat exchange core body between first air channel and second air channel.Current divider is made up of several slices, is used for air-flow is divided into some shunt, these some shunt are compiled to be two-way again, and towards two different directions, and two bursts of air-flow each intervals.Heat exchange core body inside has formed some the air channels that are isolated from each other.First blower fan and second blower fan are installed in respectively as the D mouth of air outlet and B mouth place, so that accelerate flowing of air in two air channels.
Unlike the prior art be, indoor air inlet in this air heat-exchanging device and indoor air outlet creatively adopt the air circulation mode of air intake, following air-out, it is the top that indoor air inlet is positioned at air outlet, allow the high-temperature gas of the indoor superjacent air space air heat-exchanging device of flowing through, get back to from the air outlet of below again after cooling off indoor, the low gas of the continuous implantation temperature in indoor below.These gases heat up gradually indoor, rise gradually in the process that heats up, and just in time meet the principle that hot-air rises.This air circulation mode that goes up air intake, air-out down meets the rule that air flows naturally, can increase air-flow circulation radius, forms a systemic circulation wind path, thereby strengthens indoor air convection, accelerates rate of heat exchange.
