Abstract
The utility model discloses an indoor and outdoor air heat exchanger comprising an air conduit and an indoor heat exchanger, wherein the air conduit is a return coiled pipe, and the air inlet and the air outlet of the air conduit are outdoor; an air circulation conduit between the air outlet and the air inlet is indoor; the air circulation conduit is covered with an indoor heat exchanger; the air inlet and the air outlet of the air conduit are respectively provided with a metal gauze filter; and the air conduit is provided with an induced draft fan close to the air outlet. Compared with the existing heat exchanger, the indoor and outdoor air heat exchanger adopts the return coiled pipe as the air conduit, thus increasing the circulation exchange area and achieving better effect of heat exchange. Two closed passages of indoor air and outdoor air that flow reversely and are mutually isolated overcome the defect that a fresh air system brings dust in. The metal gauze filters arranged at the air inlet and the air outlet of the air conduit can stop large particle dust and insects, small animals and the like from entering the air conduit.
Description
Technical field
The utility model relates to a kind of heat exchanger, relates in particular to a kind of indoor-outdoor air heat exchanger.
Background technology
At present in most communications, electric power and equipment machine room are because clean requirement, all need airtight fully, the heat that equipment sends can cause the temperature in the machine room to rise to the degree that jeopardizes the equipment operate as normal, therefore must take the cooling means to machine room, conventional cooling means install an air-conditioner exactly, air-conditioning can well reach the purpose of cooling, but the energy consumption of air-conditioning is higher, the service life of normal domestic air-conditioning is shorter, the price of industrial air-conditioning is higher, therefore the power consumption of air-conditioning and the use cost of equipment have just occupied the especially prime cost of the communication machine room of communication operator of machine room, the power consumption of air-conditioning has occupied 40%～50% of the whole power consumption of communication machine room according to statistics, and the energy consumption that therefore reduces the cooling of machine room has also just become to reduce the main means of machine room power consumption.
The means of conventional reduction cooling energy consumption mainly contain: take more high efficiency air-conditioning, as convertible frequency air-conditioner, because the heating power of some machine rooms is constant, therefore take convertible frequency air-conditioner can not effectively lower air conditioning energy consumption, take VMC, be a kind of effective energy-conservation means, but because VMC is to introduce outdoor new wind indoor, therefore destroyed the seal of machine room, also brought an outdoor dust of more serious problem also along with in the new wind inlet chamber with stylish wind introducing, be deposited on the electronic equipment, cause device damage, so VMC is also inapplicable in the airtight place of needs.
The utility model content
Problem at above-mentioned prior art existence, the utility model purpose is to provide a kind of indoor heat of air exchange that can make full use of outdoor lower temperature, while is owing to two air flues of the indoor and outdoors air of the mutual isolation of adopting airtight reverse flow, solve VMC and can bring the drawback of dust into, had the indoor and outdoor heat exchanger of advantage of the low energy consumption of VMC simultaneously again.
The technical solution of the utility model is: a kind of indoor-outdoor air heat exchanger, comprise air duct and indoor heat converter, described air duct adopts the reciprocation type coiled pipe, the air inlet of described air duct and gas outlet are positioned at outdoor, circulation of air pipeline between gas outlet and the air inlet is positioned at indoor, and be coated with indoor heat converter on the circulation of air pipeline, the air inlet of described air duct and place, gas outlet are provided with metal net shaped filter respectively, are provided with air-introduced machine near its place, gas outlet in the described air duct.
As preferably: be provided with fan near the described indoor heat converter, the air outlet wind direction of described fan is opposite with the air overall flow direction of air duct.
As preferably: described air duct is that copper or PVC material are made.
As preferably: described indoor heat converter material is slim aluminium, and the cross section can be rectangle or triangle.
The beneficial effects of the utility model are: air duct described in the utility model adopts the reciprocation type coiled pipe; increase the circulation exchange area; reach better heat exchange effect; the air inlet of described air duct and gas outlet are positioned at outdoor; circulation of air pipeline between gas outlet and the air inlet is positioned at indoor; and be coated with indoor heat converter on the circulation of air pipeline; make full use of the indoor heat of air exchange of outdoor lower temperature; simultaneously owing to adopt two air flues of the indoor and outdoors air of airtight mutual isolation; solve VMC and can bring the drawback of dust into; the air inlet of described air duct and place, gas outlet are provided with metal net shaped filter respectively; can block bulky grain dust and insect; toys etc. enter air duct; be provided with air-introduced machine near its place, gas outlet in the described air duct; outdoor cold air is introduced the incoming air conduit road, finish exchange heat with indoor hot-air.
Be provided with fan near the described indoor heat converter, the air outlet wind direction of described fan is opposite with the air overall flow direction of air duct, reaches the purpose of reverse flow, improves the efficient of exchange heat.
Described air duct is that copper or PVC material are made, and anti-aging resistance to corrosion is strong.
Described indoor heat converter material is slim aluminium, and slim aluminium heat-exchange capacity is strong, and the cross section can be rectangle or triangle, increases contact area.
