The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; The base station equipment subregion temperature-controlling system based on VMC of the utility model comprises first air-conditioner 6 and the VMC; Batteries in the machine room 20 of base station disposes accumulator tank 1; As air intake surface 11 and outlet air surface 12, the air intake cover 5 of VMC is switched to accumulator tank 1 through first blast pipe 2 by air intake surface 11 respectively in two opposite flanks of accumulator tank 1, and outlet air surface 12 is provided with gas outlet 10 to be opened/closed.During VMC work, first blast pipe 2 is at first introduced accumulator tank 1 with outdoor cold air, and cold air sheds from the gas outlet 10 that outlet air surface 12 is in open state to battery cooling back, machine room 20 is lowered the temperature again; After battery temp reached set point of temperature, VMC quit work, and gas outlet 10 is closed, so that the insulation of accumulator tank 1.

Between summer or megathermal period, need to start air-conditioning temperature-reducing; Therefore; Further, be provided with air inducing device 21 at the side of the air outlet of first air-conditioner 6, the air outlet of air inducing device 21 is switched to accumulator tank 1 through first induced duct 3 by air intake surface 11; Be provided with the first air channel spacer assembly 8 between first blast pipe 2 and first induced duct 3; Prevent in the VMC that the air intake machine is blown into outdoor cold wind in first air-conditioner 6 or first air-conditioner 6 blows to the outdoor wasting of resources that causes with cold air through first blast pipe 2, the cold air that first air-conditioner 6 blows out is preferentially to the battery cooling, and the inferior cold air that the cooling back sheds from the gas outlet 10 that is in open state is lowered the temperature to station again; After battery temp reached set point of temperature, first air-conditioner 6 quit work, and gas outlet 10 is closed, so that the insulation of accumulator tank 1.

The utility model preferably is provided with air inducing device 21, rather than simply the air outlet of first air-conditioner 6 is imported to accumulator tank 1 through first induced duct 3 by air intake surface 11, is to consider from following: in the accumulator tank 1 during 15 ℃-25 ℃ of temperature; And the environment temperature of machine room 20 maybe be more than 30 ℃, and for satisfying the requirement of base station equipment to temperature, this moment first, air-conditioner 6 needed machine room 20 coolings; But need not lower the temperature to accumulator tank 1, therefore, at the side of first air-conditioner, 6 air outlets; For example above the outlet grid of air-conditioning; Install air inducing device 21 additional, when temperature was suitable in the accumulator tank 1, air inducing device 21 quit work; No air-conditioning cold air is sent in the accumulator tank 1, and air-conditioning cold air is only to machine room 20 coolings; And when temperature in the accumulator tank 1 rises to more than 25 ℃; Air inducing device 21 will start; The part cold wind that air-conditioning is blown out is incorporated in the accumulator tank 1; Air-conditioning is also to machine room 20 coolings simultaneously, and the temperature because of its air outlet place when also having avoided first air-conditioner 6 just to start causes damage to battery in the accumulator tank 1 far below 25 ℃ (possibly be 7～8 ℃).Like this, the cold air of air outlet with after machine room 20 interior high temperature airs mix, gets in the accumulator tank 1 earlier again, and temperature is more suitable.

Equally, when needs are heated up by 6 pairs of machine rooms of first air-conditioner 20, the effect of air inducing device 21 with regard to corresponding become with the part heating installation that comes out by first air-conditioner 6 with machine room 20 in Cryogenic air mix after, import again in the accumulator tank 1.

As shown in Figure 3; Because the power of first air-conditioner 6 that existing machine room 20 is equipped with is bigger; Generally reach 3-5P, the power consumption of its compressor start is relatively also big, from energy-conservation consideration; Can be the accumulator tank 1 independent air outlet that is equipped with second air-conditioner, 7, the second air-conditioners 7 and be switched to accumulator tank 1 by air intake surface 11 through second induced duct 4 and the first air channel spacer assembly 8.

Though the cooling efficient of second air-conditioner 7 is not as large power air-conditioned; But the power consumption of its compressor start is much smaller than large power air-conditioned; Further energy-conservation when ensureing the temperature requirement of indoor each electrical equipment, also promptly, during 15～25 ℃ of outdoor temperatures only by VMC to accumulator tank 1 cooling; To machine room 20 coolings, this moment, first and second air-

conditioner

6,7 did not all start its cold air that blows out again; When 25～30 ℃ of outdoor temperatures; Can start 1 cooling of 7 pairs of accumulator tanks of second air-conditioner; Its cold air that blows out is again to machine room 20 coolings; And VMC only is used for machine room 20 blowings, cooling through second blast pipe 19 under the control of the second air channel spacer assembly 18, and this moment, first air-conditioner 6 did not start; Too high as more than 30 ℃ the time when outdoor temperature, thus VMC be can not lower the temperature to machine room the time effectively, first air-conditioner 6 starts and to machine room 20 coolings, also accumulator tank 1 is lowered the temperature down in 21 effects of air inducing device simultaneously, and second air-conditioner 7 can quit work at this moment.

Its outlets of the first air channel spacer assembly 8 control can only or be communicated with first blast pipe 2; Be communicated with second induced duct 4 and first induced duct 3; When being communicated with between the outlet of first induced duct 3, second induced duct 4 and the first air channel spacer assembly 8; Its air channel division board 24 first blast pipe 2 of blockading, the cold air of avoiding air-conditioner to blow out blows to the outdoor wasting of resources that causes through first blast pipe 2, has also stoped outdoor hot gas to be scurried into simultaneously; When being communicated with between the outlet of first blast pipe 2 and the first air channel spacer assembly 8, its air channel division board 24 blockade first induced duct 3 and second induced duct 4.The control system by whole temperature-controlling system of starting or stoping then of first air-conditioner 6 and second air-conditioner 7 is according to each environment temperature decision such as outdoor temperature, battery in-cabinet temperature and computer room temperature.

As shown in figures 1 and 3, the said first air channel spacer assembly 8 is for being built-in with the spacer plate box 9 of air channel division board 24, is communicated with refrigerator pipe 23 between the air intake surface 11 of spacer plate box 9 and accumulator tank 1.Air channel division board 24 can rotate around division board rotating shaft 25; When carrying out temperature control by air-

conditioner

6,7; First induced

duct

3 or 4 air-out of second induced duct are blown air channel division board 24 and are rotated around division board rotating shaft 25; First induced duct 3 or second induced duct 4 are communicated with refrigerator pipe 23, and simultaneously air channel division board 24 is blockaded and is communicated with between first blast pipe 2 and the refrigerator pipe 23; During by the VMC temperature control, 2 air-out of first blast pipe, air channel division board 24 is around division board rotating shaft 25 backward rotation, and first blast pipe 2 is communicated with refrigerator pipe 23, and simultaneously blockade first induced duct 3 and second induced duct 4 of air channel division board 24 is communicated with refrigerator pipe 23.

Energy-conservation for further; As shown in Figure 2; Can be fitted with thermal conductance tracheae 16 on 14 tops of the heat-producing device in the machine room 20, thermal conductance tracheae 16 is connected to outdoor exhaust outlet through exhaust blower 15, in the summer high temperature period; The heat that heat-producing device 14 sends directly is discharged to outdoor under exhaust blower 15 effects, reduces the air-conditioning power consumption widely.

In the winter time, therefore the heating that can utilize heat-producing device 14 comes out for ease of heat indoor intensification, and on said thermal conductance tracheae 16, digging has venthole 17, and this moment, exhaust blower 15 was out of service.

Said exhaust blower 15, VMC and first air-conditioner, 6 signals are connected to same controller.Utilize controller to realize controlling as follows with energy-conservation:

In outdoor temperature is 15～25 ℃ and temperature when meeting the demands, and need not start air-conditioner, only starts VMC, is blown out to machine room 20 coolings again after directly outdoor cold air being incorporated into accumulator tank 1, and exhaust blower 15 is to outdoor discharge hot gas in the case; If the equipment heating amount is excessive, when causing but overshoot temperature of indoor temperature, then start the air-conditioner auxiliary temperature-reducing as 38～40 ℃, exhaust blower 15 shuts down in case directly be discharged to cold air outdoor simultaneously;

Because the battery-operated temperature requirement is between 15～25 ℃, therefore, most times can utilize outdoor natural cold resource aeration-cooling to battery and base station in 1 year, and are energy-conservation widely.

Like Fig. 1 and shown in Figure 4; On above-mentioned all scheme bases; Can further consider that also said air intake cover 5 is connected with first blast pipe 2 with the second air channel spacer assembly 18 through fresh wind tube 22; Fresh wind tube 22 is communicated with accumulator tank 1 outer machine room 20 through the second air channel spacer assembly 18 and second blast pipe 19 in addition, and the second air channel spacer assembly, 18 control fresh wind tubes 22 are communicated with first blast pipe 2 or second blast pipe 19.When outdoor temperature was 15 ℃-25 ℃, the second air channel spacer assembly 18 stoped second blast pipe 19 to be communicated with fresh wind tube 22, and first blast pipe 2 is communicated with fresh wind tube 22 simultaneously, was convenient to outdoor new wind accumulators cabinet 1 blowing, cooling; When outdoor temperature is more than 25 ℃ the time; The second air channel spacer assembly 18 stops first blast pipe 2 to be communicated with fresh wind tube 22, and second blast pipe 19 is communicated with fresh wind tube 22 simultaneously, and outdoor cold resource still capable of using is to machine room 20 blowings, cooling; But because this moment, first blast pipe 2 was not communicated with fresh wind tube 22; The cold wind that first air-conditioner 6 or second air-conditioner 7 blow out can not blow out outdoor via first blast pipe 2, guarantees the environment temperature of accumulator tank 1, thereby makes good use of the cold resource of each part most possibly.

As shown in Figure 4, the second air channel spacer assembly 18 can be under the control systemic effect of whole temperature-controlling system, by 26 upsets of driven by motor turnover panel, turnover panel 26 rotations can seal first blast pipe 2, second blast pipe 19 the two one of, also can adopt structures such as pipeline valve certainly.

As shown in Figure 1, blade window 13 can be adopted in said gas outlet 10 to be opened/closed, and is simple in structure, when air intake surface 11 has air intake, can be pushed open naturally at air-flow effect lower blade.

At this moment, preferably on outlet air surface 12, corresponding to blade window 13 inboard places magnet piece is housed, correspondence position is equipped with small iron plate on the blade window 13 simultaneously; When closing gas outlet 10; Blade closes sternlyer under magneticaction, guarantees the seal of accumulator tank 1, reduces accumulator tank 1 interior cold and scatters and disappears.
