The specific embodiment
As shown in Figure 1, the room air heat reclamation device that the utility model provides comprises: bring the first heat exchange cavity 8 of outlet into, its import entered with indoor the connection for room air, and outlet is discharged for room air; Bring the second heat exchange cavity 7 of outlet into, it is provided with drainage blower fan 2 with the indoor exit that is communicated with, drainage blower fan 2 is used for introducing indoor by the second heat exchange cavity 7 outdoor air when initial, make indoor generation pressure-fired, under the effect of pressure-fired, room air is discharged to outdoor by the first heat exchange cavity 8, therefore can utilize drainage blower fan 2 to need more to drive this room air heat reclamation device operation under the news at room air; The first heat exchange cavity 8 and the second heat exchange cavity 7 are arranged side by side, and has a shared cavity wall 6, cavity wall 6 is the heat conduction sidewall, be penetrated with several row of horizontal settings on the heat conduction sidewall and play the heat pipe 5 of heat exchange effect, the two ends of heat pipe 5 lay respectively in the first heat exchange cavity 8 and the second heat exchange cavity 7, and liquid refrigerant is housed in the heat pipe.The first heat exchange cavity 8 and the second heat exchange cavity 7 outer wall except that shared cavity wall 6 forms the shell 9 of room air heat reclamation device.
The import department of the first heat exchange cavity 8 is provided with the first micro power opened non-return valve 1 in the present embodiment, is used to prevent that outdoor air from passing through the first heat exchange cavity, 8 adverse currents to indoor; The exit of the second heat exchange cavity 7 is provided with the second micro power opened non-return valve 1 ', is used to prevent that room air from passing through the second heat exchange cavity, 7 adverse currents to outdoor.The import department of the first heat exchange cavity 8 is provided with first valve 3 that is used for this import of opening and closing; The exit of the second heat exchange cavity 7 is provided with second valve 3 ' that is used for this outlet of opening and closing.When not needing to upgrade room air, can close first valve 3 and second valve 3 '.The exit of the import department of the first heat exchange cavity 8 and the second heat exchange cavity 7 is provided with the graininess dust that is used for filter chamber's outer air and prevents the airstrainer 4 that insect inlet chambers such as mosquito, fly are interior.Cavity wall adopts copper sheet to make.
As shown in Figure 1, the profile of the first heat exchange cavity 8 and the second heat exchange cavity 7 is all S-shaped.Its shared cavity wall 6 is also S-shaped, and heat pipe 5 is arranged on back bending place of shared S shape cavity wall 6, and each back bending place is provided with three heat extraction pipes 5.The first heat exchange cavity 8 reaches the second heat exchange cavity 7 and in the import department near an outdoor side stormproof louvre air port 11 is set all in the exit near an outdoor side, is used for stoping rainwater to enter cavity.As Fig. 2 is the vertical view of room air heat reclamation device in this new embodiment, and Fig. 3 is the left view of room air heat reclamation device in the present embodiment.
Adopt the indoor heat reclamation device in the present embodiment, only need when initial, open drainage blower fan 2, after forming Natural Circulation, can close drainage blower fan 2.In order to save the energy, the small-sized low noise drainage blower fan of above-mentioned drainage blower fan 2 preferred employings.Provide the operation principle and the course of work of this novel indoor heat reclamation device below.
Room air heat reclamation device in the present embodiment is suitable for two seasons of summer in winter.Present embodiment only is example with the winter, the first heat exchange cavity 8 is called hot-air loss of heat cavity, the second heat exchange cavity 7 is called cold air gets hot cavity, hot power room air heat reclamation device gets heat pipe 5 that hot cavity, the setting of number row of horizontal play the heat exchange effect, copper sheet, small-sized low noise drainage blower fan 2, two airstrainers 4, two air doors 3 and 3 ', two micro power opened non-return valve 1 by the cold air of the hot-air loss of heat cavity of above-mentioned heat reclamation device shell 9, S shape, S shape and 1 ', two accessory such as stormproof louvre air port 11 formed.When room air is contaminated, open two air doors, open small-sized low noise drainage blower fan 2, get hot cavity from outdoor introducing fresh air by cold air on the one hand, indoor foul atmosphere flows to outdoor through hot-air loss of heat cavity on the one hand.When indoor foul atmosphere is discharged into when outdoor through hot-air loss of heat cavity, near the heat in the heat pipe 5 absorption foul atmospheres of hot-air loss of heat cavity one side, make the liquid refrigerant evaporation in the horizontally disposed heat pipe 5, working substance steam flows to cold air from the top of heat pipe and gets hot cavity one side, refrigerant vapor is met cold back condensation, exchange heat is given the cold air that flows into; Copper sheet also is heated, and with the cold air of heat biography in the hot cavity 7 of the cold air of opposite side, because the hot air temperature in the hot-air loss of heat cavity descends, increase in density produces decline power; Simultaneously, outdoor fresh cold air gets hot cavity by cold air and flows into when indoor, and the heat heating that is discharged by heat pipe 5 and copper sheet in process of flowing makes the steam state working medium condensation heat release in the heat pipe 5.Steam state working medium is converted into liquid state, flow back into hot-air loss of heat cavity from the bottom of heat pipe 5; Heated copper plate 6 also plays the effect of heats cold air; The temperature that cold air is got in the hot cavity rises, and density diminishes, and produces climbing power.One rise and one drop, this process forms Natural Circulation trend.At this moment can close small-sized low noise drainage blower fan 2, realize Natural Circulation.Whole device construction is simple, is convenient to operation, reaches the effect of upgrading room air when being intended to reduce indoor thermal loss.
Equally, above-mentioned room air heat-exchange device is applied to summer, and the first heat exchange cavity 8 is called cold air and gets hot cavity, and the second heat exchange cavity 7 is called hot-air loss of heat cavity, utilize above-mentioned heat exchanging process can form Natural Circulation too, detailed process no longer describes in detail here.
This novel room air heat-exchange device that provides is provided, and the initial driving force of circulation comes from small-sized low noise drainage blower fan; After producing draught head in two cavitys, small-sized low noise drainage blower fan can cut out, and has therefore saved the energy.When discharging indoor foul atmosphere introduction outdoor fresh air, give introduction indoor fresh air the exchange heat of indoor discharge air.Accomplish to keep the room air heat, can upgrade the purpose of room air again.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
