Embodiment
Below introduce specific embodiment of the present utility model in detail, the example is wherein represented identical parts with identical label as shown in drawings in full.
Embodiment one:
What present embodiment was described is a kind of execution mode of equipment enclosure of subregion temperature control, can be used for outdoor distributed communication base station.
As shown in Figure 1, rack (101) has double-deck side plate, and cabinet door (102) is equipped with in the front.The bottom and the top of the outer side plate of rack and back plate are provided with louvre (103), are provided with air ejector fan group (104) at the top.Outside air enters the rack interlayer from louvre, and flow out at the top from rack under the effect of air ejector fan, and the heat that equipment in the rack sends is discharged.
Be provided with independently battery compartment (105) in the rack (101), adopt the modular global design, integral installation also can integral demounting when needing in rack after the processing and manufacturing separately.Battery compartment (105) is installed in the middle part of rack, is used for installing storage battery, and the equipment compartment of rack just is divided into two zones (106) and (107) up and down, is used to install miscellaneous equipment, particularly high power device.
Battery compartment (105) adopts insulated design, is provided with insulating (108).When box sizes hour, insulation layer (108) can integral foam processing, the about 25-50mm of heat insulation layer thickness; When box sizes is big, can be with the surface that is assembled in casing after the needs cutting of warming plate according to physical dimension.The door body (109) of battery compartment also is provided with the insulation heat insulation layer, is provided with an envelope (110) between door body (109) and the casing, can reduce incubator and close the back from the slit source heat between the Men Tiyu casing.Battery compartment (105) is provided with the cable-through hole (111) that communicates with equipment compartment, and cable-through hole is furnished with sealing plug.Battery compartment (105) also is provided with and the extraneous steam vent (112) that communicates.Open steam vent during charging, just pernicious gas in time can be discharged.
This equipment enclosure is provided with the semiconductor refrigerating module at the rear of battery compartment (105).The cold junction radiator (114) of semiconductor cooling device (113) is positioned at the top at equipment compartment rear portion, and hot-side heat dissipation device (115) has fin and draught fan (116) to strengthen radiating effect.Refrigeration module is used for controlling the temperature of battery compartment, and when controller detected by temperature sensor that temperature is higher than design temperature in the storehouse, refrigeration module started to battery compartment freezes, and when temperature was lower than design temperature in the storehouse, refrigeration module quit work.
Communication in the communication base station equipment, power module have different environmental requirements with batteries for condition of work.The hot adaptability of a new generation communication module and power module is stronger, also can stable operation under higher temperature, but equipment power dissipation is bigger, need to strengthen heat transfer to reduce working temperature, and especially need be to the direct forced heat radiation on the space of points of high power device.As long as these equipment are controlled at below 30 ℃ for ambient temperature and just can meet the demands, and allow to be no more than 35 ℃ of short time work, be no more than 55 ℃ to guarantee device ambient temperature of living in but will carry out good air distribution to the heater members part in temperature.When the external world was in hot weather refrigerating capacity deficiency, intelligent communication device can also reduce power consumption to guarantee equipment safety operation by adaptive techniques such as frequency reducings the short time.
Though and the batteries caloric value is little, residing temperature range is had relatively high expectations, this system should be controlled at 20-25 ℃ temperature range, allows to be no more than 30 ℃ of short time work in temperature, could prolong the useful life of batteries.Storage battery can generate heat when charging, but caloric value is less, has only tens watts usually.The heat load that external environment was brought when the heat-insulation and heat-preservation casing can significantly reduce summer high temperature, so the battery rack of heat-insulation and heat-preservation significantly is lower than the common batteries cabinet in the heat load of high temperature season.Typically, the battery rack of a volume 250L is installed in outdoor, wants the refrigeration plant of adapted refrigerating capacity 1000-1500W when casing is not done insulation, and adopts behind the insulation casing as long as the refrigerating capacity of 150-200W can meet the demands.Further, even the refrigeration plant cisco unity malfunction, temperature keeping battery cupboard can guarantee that temperature is no more than 35C in 6 hours.
Embodiment two:
