Specific embodiment
The utility model is described in further detail below in conjunction with description of drawings and embodiment.
In Fig. 1, Fig. 2, Fig. 3, the first embodiment shown in Figure 4, a kind of air heat recovery device comprises heat-exchanger rig (1), it is characterized in that, it alternately is comprised of the even number cross air flue, also comprises central air hose interface and outer bostle pipe.Each air channel is combined by heat exchange dividing plate (4), air channel top panel (3), air channel lower panel (5).Two adjacent air channels cross air flue that partners, two adjacent air channels share heat exchange dividing plates (4), and its direction of ventilation is 90 degree and intersects.Many to the spin cone structure of cross air flue around the formation closure.Described heat exchange dividing plate (4) is that the square heat transfer is dull and stereotyped, utilizes the good material of heat transfer coefficient to make.Air channel top panel (3) is fan-shaped, and air channel lower panel (5) is fan blade type, both be stitched together form one complete fan-shaped, their radius is all equal with the foursquare air-duct clapboard length of side.Described central air hose interface is circular, is to connect outside ventilation shaft; The looped duct that the space that outer bostle pipe and central air hose surround forms is air channel, outer ring (6); Air channel, outer ring (6) is sleeve type structure outside being enclosed within central air hose (2).Cold and hot working medium flows in air channel, outer ring (6) and central air hose (2) respectively.
In Fig. 1, Fig. 3, the second embodiment shown in Figure 4, different according to the direction of cold and hot Air Flow, be divided into downflow type and reverse-flow.Downflow type: two strands of air-flows flow into from air channel, outer ring (6) and the central air hose (2) of heat-exchanger rig (1) one end respectively, high temperature fluid transfers heat to cryogen by heat-exchanger rig (1), and fully two fluid streams after heat exchange flow out from central air hose (2) and air channel, outer ring (6) of heat-exchanger rig (1) other end respectively again.Reverse-flow: a fluid streams flows into from air channel, outer ring (6) or the central air hose (2) of the other end from the central air hose (2) of heat-exchanger rig (1) one end or air channel, outer ring (6) and flows out, another fluid streams flows out from central air hose (2) or air channel, outer ring (6) of the other end from air channel, outer ring (6) or central air hose (2) inflow of heat-exchanger rig (1) other end, and two fluid streams obtain sufficient heat exchange in heat-exchanger rig (1).
In Fig. 1, Fig. 2, Fig. 3, the 3rd embodiment shown in Figure 4, this heat-exchanger rig (1) is according to the difference of applicable cases, and the difference by the heat exchange unit number can produce the different heat-exchanger rig of air channel different densities (1).Can a plurality of these heat-exchanger rigs (1) series connection use in concrete use procedure, with the reinforcement heat transfer effect, and save heat transfer space.Can install one section at this and install the equipment such as blower fan additional in the certain applications places.
In Fig. 1, Fig. 2, Fig. 3, the 4th embodiment shown in Figure 4, the normal domestic use air-conditioned room adopts split-type air conditioner usually, and recycling space air does not have new wind to add, and is unfavorable for the human physiology requirement.Directly adopt traditional exhaust equipment cost lower, but will directly cause air conditioning energy consumption to increase severely, and larger on the indoor thermal comfort environment of rural impact.Can guarantee more comfortable indoor air quality and install separately the fresh-air ventilation unit additional, but will greatly increase financial cost, take simultaneously space impact building attractive in appearance.
With this heat-exchanger rig (1) and blower fan combination, and coordinate suitable air diffuser just can reach not only to satisfy room air hygienic requirements but also economical and energy saving purpose.
For the air exhaust heat recovery system of Large Central Air Conditioning System system, can adopt equally this heat-exchanger rig (1).The mode of a plurality of heat-exchanger rigs (1) with serial connection is arranged in the air exhaust heat recovery system, in the requirement of satisfying Waste Heat Recovery, can greatly reduces taking the machine room space.
This heat-exchanger rig (1) can with the perfect adaptation of supply and exhaust dual-purpose type air diffuser, when guaranteeing that indoor air-supply requires, can the heat that indoor exhaust wind is taken away in time be reclaimed, realize energy-conservation purpose.
Simultaneously, at industrial circle, such as the boiler plant in steam power plant, for realizing the purpose of economical and energy saving, air preheater usually is set in boiler back end ductwork, and high-temperature flue gas passes to air with heat by preheater, to reclaim the used heat in smoke evacuation, improve air themperature, thereby improve boiler efficiency.The designed air heat retracting device of the utility model can substitute existing air preheater for boiler, reaches the purpose that reclaims used heat, fuel saving.
The principle of utilizing thermal current rising cold air to descend combines this heat-exchanger rig (1) and chimney and can be designed to the novel building automatic air interchanger.Because altitude air density is less, the high-altitude wind speed can be taken away the foul atmosphere in room by chimney more greatly, and outdoor new wind is introduced the room, utilizes simultaneously this heat-exchanger rig (1) to reclaim and discharges airborne part heat.Indoor basic air-conditioning requirement had both been satisfied in this design, and was less on the indoor thermal comfort environment of rural impact again, simultaneously, do not need power, reached the requirement of energy-conserving and environment-protective.
