Abstract
The utility model relates to an air-conditioning energy-saving ventilation fan, comprising a housing and a cold-hot exchanger which is arranged in the housing and is composed of an electric fan and a plurality of exchanging plates. With the air inlets on two adjacent exchanging plates arranged alternatively, the air streams entering the cold-hot exchanger from the same side have the same temperature and the same direction and the air streams on the adjacent exchanging plates have opposite directions and large temperature difference, so that the heat is exchanged between the exchanging plates, and the utility model achieves the purpose that the indoor and the outdoor air are exchanged sufficiently without the energy loss of air conditioners. The utility model is especially suitable for rooms with air conditioners.
Description
The utility model relates to a kind of ventilation fan, especially a kind of energy-conservation ventilation fan that is used to be equipped with air-conditioned room.
For air conditioner is played a role better, will there be the better seal performance in the general room of dress air-conditioning that requires.Because it is airtight, room air can not exchange with outside fresh air, harmful components such as Carbon Dioxide in Air, nitrogen oxygen can obviously increase, some bacterium, mould, microorganisms that are harmful to human body also can breed rapidly, indoor environment runs down, live and work in this environment for a long time, it is uncomfortable in chest, dizzy, weak from head to foot that people can feel, totally unfavorable to health.In order to improve above-mentioned environment, the method for taking to install additional at air-conditioned room common ventilation fan that has makes indoor-outdoor air produce certain exchange, has greatly influenced the work of air-conditioning effect and do like this, and energy loss is big.
The purpose of this utility model is to provide a kind of operate as normal that neither influences room conditioning, substantially loss of energy not, room air and extraneous fresh air are exchanged, its temperature and indoor air temperature are approaching when in the outside air inlet chamber, the energy-conservation ventilation fan of holding chamber inner air flow.
The purpose of this utility model is achieved in that electric fan is placed a housing of being made up of outer cover and base plate, cool-heat-exchanger also is housed in housing.
Above-mentioned cool-heat-exchanger is made up of the multi-disc power board, and they are connected in one by securing member.Power board is provided with the wind deflector of projection, is provided with breach on wind deflector, makes and forms the labyrinth type gas channel with air inlet and air outlet on a slice power board.
Because air inlet on the power board and air outlet center line angle are 90 degree, when forming cool-heat-exchanger as the air inlet on the adjacent power board is staggeredly placed, it is spaced air inlet that cool-heat-exchanger then is rendered as a side, and opposite side is spaced air outlet.When electric fan is worked, outdoor and room air enter the different power boards of cool-heat-exchanger respectively, gas flow temperature difference, the direction of flowing through on the two adjacent power boards are opposite, produce power exchange to each other, outdoor air through power board by the air inlet inlet chamber in the time its temperature near indoor temperature, the energy that has so promptly reached not loss air-conditioning can carry out the purpose of air exchange again.
Outstanding advantage of the present utility model is: carry out the exchange of indoor-outdoor air under the condition of not loss air conditioner energy substantially, keep the air of dress air-conditioned room fresh, make the people feel more comfortable, the joy of life that the air-conditioning that can indulge in luxuriousness to one's heart's desire brings is particularly conducive to health.
Fig. 1 is the utility model overall structure schematic diagram.Fig. 2 is the A-A view of Fig. 1.Fig. 3 is the B-B view of Fig. 2.Fig. 4 is the utility model cool-heat-exchanger structural representation.Fig. 5 is a utility model power board structural representation.Fig. 6 is the C-C view of Fig. 5.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is further described: housing is made up of outer cover (1) and base plate (5), filter screen (4) and electric fan switch (6) are housed on outer cover, attaching plug is drawn from housing, and cool-heat-exchanger (3) and electric fan (2) are housed on base plate.Cool-heat-exchanger is made up of the multi-disc power board, is provided with the wind deflector (8) of projection on power board, has breach on the wind deflector, makes and forms the labyrinth type gas channel with air inlet (9) and air outlet (7) on the power board.Power board is making as non-ferrous metals such as aluminium, aluminium alloy, copper of the most handy good heat conductivity.Wind deflector can adopt identical with power board or different materials such as plastics, integral body or split production.When split production, it connects available securing member or bonding mode is carried out, and also can The combined adopt.Connection between power board also can be adopted above-mentioned connected mode.
Power board can be that rectangle, polygon also can be multiple shapes such as circle, ellipse, and when power board adopted wherein a kind of shape, the wind deflector shape on it also can be done corresponding variation.
Be fixed on electric fan on the base plate and preferably be contained in the air intake oral-lateral of cool-heat-exchanger, take to send (row) wind to the mode of interchanger exhausting.When the polylith power board is formed cool-heat-exchanger, the air inlet on adjacent two power boards is staggeredly placed, when the air inlet of a power board placed cool-heat-exchanger one side, what adjacent another piece power board placed the same side was airfast wind deflector like this.When the air inlet air intake of cool-heat-exchanger one side, what enter air inlet is the air of same temperature.Because being staggeredly placed of adjacent power board air inlet, the gas flow temperature difference, the direction that then cause entering adjacent two power boards are opposite, when flowing through separately the labyrinth type circulation road, carry out heat exchange between power board.
Claims (6)
