Description
Technical field
The utility model belongs to regulator cubicle field, relates to the heat radiation of regulator cubicle, especially a kind of cabinet of binary channels heat radiation.
Background technology
In electric device field, high power device often caloric value is very large, and heat falls apart in large-scale cabinet inside and do not go out, and has a great impact, can affect the normal operation of cabinet system because operating ambient temperature in cabinet is too high to the performance of electricity piece in cabinet.Mostly the heat dissipation wind channel of current regulator cubicle is to utilize blower fan to smoke and blows to be formed, and there is following problem: 1, air channel is not closed, can cause and leak out; 2, Duct design is unreasonable, and blower fan is taken out blowing and do not reached radiating effect; 3, Duct design is complicated, cost intensive.
By retrieval, not yet find the patent document identical with the utility model.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the cabinet that a kind of binary channels is dispelled the heat, and this cabinet science layout high power device, forms twice heat dissipation wind channel, ensure that the normal operation of high power device in cabinet in cabinet.
The technical scheme that the utility model technical solution problem adopts is:
A kind of cabinet of binary channels heat radiation, comprise the power device installed in cabinet and cabinet, reactor, the mounting panel of cabinet internal upper part is fixedly mounted with power device, in cabinet, lower mounting plate is fixedly mounted with reactor, incoming-line busbar passes through switch, power device, and cabinet busbar is connected with reactor, it is characterized in that: the power device that described mounting panel is fixedly mounted with and reactor distance cabinet-body plate leave rear gap, bottom gap is left between reactor in cabinet and bottom of cabinet bulk, in the cabinet upper end of corresponding rear gap, outer fan is installed, the ventilation hole of cabinet header board is to bottom gap, rear gap and outer fan form the external air channel in cabinet, described power device is installed on a heat sink, and going to the bottom of this radiator is provided with cooling fan, and to the radiator top of cooling fan should being communicated with and being provided with heat radiation bellows, the hot blast that these heat radiation bellows are discharged directly is discharged from top, the header board ventilation hole of cabinet to cooling fan, radiation air box-shaped becomes the air channel, inside in cabinet.
And, the rear plate in cabinet is fixed with baffler.
And, described outer fan and cooling fan upwards exhaust way, or inside air inlet mode.
Advantage of the present utility model and good effect are:
1, the utility model is inner at large-scale cabinet, at the top, air channel, rear portion of cabinet, blower fan is installed, utilize the layout of electricity piece in cabinet cabinet, l-shaped air duct radiation space will be split before and after cabinet, and cabinet busbar is also in the duct space of mounting panel self-assembling formation, self-ventilation mouth is gone to the bottom the gap again in cabinet between rear portion and form external air channel in cabinet, directly can evacuate the caloric value of busbar like this; Set baffler can make ventilation circulation smooth and easy, makes the heat radiation of each high power device obtain the improvement of essence.
2, the utility model installs blower fan bottom the radiator of large-scale power device, in cabinet, self-ventilation mouth is through the radiator air passage formation internal heat dissipating air channel of high power device to top, and directly dispel the heat in the space of cabinet busbar in this internal heat dissipating air channel, better effects if.
3, the utility model can adopt the mode of negative pressure exhausting to take cabinet hot inside air out of cabinet, also in malleation mode of drying, cabinet cool exterior air can be blown into cabinet internal heat dissipating, the air blown into discharges heat radiation respectively according to the air channel, inside of cabinet and external air channel, Duct design science, and be convenient to installing/dismounting, reduce cost.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
A kind of cabinet of binary channels heat radiation, comprise power device 2, the reactor 8 installed in cabinet 6 and cabinet, the mounting panel 3 of cabinet internal upper part is fixedly mounted with power device, in cabinet, lower mounting plate is fixedly mounted with reactor, incoming-line busbar 7 is connected with reactor by switch, power device cabinet busbar 5.
Innovative point of the present utility model is:
1, the power device that is fixedly mounted with of described mounting panel and reactor distance cabinet-body plate leave rear gap, bottom gap is left between reactor in cabinet and bottom of cabinet bulk, be provided with outer fan 9 in the cabinet upper end of corresponding rear gap, ventilation hole 11 to the bottom gap of cabinet header board, rear gap and outer fan form the external air channel in cabinet; In order to increase the wind effect of external air channel, the rear plate in cabinet being fixed with baffler 12, realizing effective water conservancy diversion, reduce the temperature in cabinet.
2, described power device is arranged on radiator 4, and going to the bottom of this radiator is provided with cooling fan 10, to should cooling fan radiator top be communicated be provided with heat radiation bellows 1, these heat radiation bellows discharge hot blast directly discharge from top; The header board ventilation hole of cabinet to cooling fan, radiation air box-shaped becomes the air channel, inside in cabinet, this inner air channel can effectively discharge incoming-line busbar, power device and cabinet busbar and install the heat that power device on a heat sink produces.
Outer fan and cooling fan can be the forms of upwards air draft, also can be the forms of air intake; This form can be carried out according to the actual needs.
Binary channels radiating mode designed by the utility model, two passages complement one another, and make the heat radiation of whole power device reach high level.
