Description

A kind of ventilation heat abstractor of high-power components
Technical field
The utility model relates to a kind of ventilation heat abstractor of high-power components, refers in particular to a kind of ventilation heat abstractor that is applicable to the high-power components of electrical panel cabinet.
Background technology
The extensive use of high-power components; Its heat radiation becomes a very important problem; A plurality of high-power components especially are installed in the electrical panel cabinet, and the heatproof condition of each high-power components is not simultaneously, the heatproof condition is low that high-power components is overheated easily; When exceeding its high-temperature resistant condition, will be damaged, thereby cause the whole system operation unreliable.In the prior art,, mainly adopt cooling fan, force the heat exchange heat radiation directly facing to the radiator blowing of high-power components for solving the heat dissipation problem of high-power components.Yet this radiating mode has following defective:
One, this heat exchange method forms disorderly air-flow easily in the electrical panel cabinet, and the gas after the heat exchange can't all be discharged, and does not have good thermolysis;
Two, the radiator heat exchange efficiency is low, is unfavorable for the overall ventilation and heat of electrical panel cabinet, and the high-power components big for caloric value just can't satisfy its radiating requirements, and high-power components is damaged.
In view of many defectives of high-power components heat abstractor in the prior art, the inventor develops a kind of high-power components heat abstractor that overcomes above-mentioned defective, and this case produces thus.
The utility model content
The purpose of the utility model is to provide a kind of high-power components ventilation heat abstractor of simple in structure and good heat dissipation effect.
For reaching above-mentioned purpose, the solution of the utility model is:
A kind of ventilation heat abstractor of high-power components comprises cabinet, duct shield, power component fin and cooling fan; Duct shield is installed in the cabinet, and the fin and the cooling fan of power component are installed in the duct shield successively, and cooling fan is positioned at power component fin below; This duct shield lower end is provided with air inlet, and the upper end sets out the air port, and air outlet is positioned at the top of cabinet, and relative with the opening of cabinet.
Further, be provided with mounting panel in the cabinet, duct shield is fixed on the mounting panel.
Further, the power component fin is more than two and two, and the number of cooling fan is corresponding with the power component fin.
Further, be provided with air exhauster between the opening of cabinet and the duct shield air outlet, air exhauster will be extracted out outside the cabinet via the opening of cabinet through heat-exchanged air.
Further, the air inlet of duct shield is set to " horn mouth " type.
After adopting such scheme; Because the power component fin and the cooling fan of the utility model all place in the duct shield; By cooling fan, the feasible wind speed flow faster that places the power component fin surface in the duct shield is concentrated hot blast outside the discharge electrical panel cabinet; Reduce the temperature rise of electrical panel cabinet, thereby guaranteed the result of ventilating heat dissipation of high-power components.
On the other hand, the utility model just all places power component fin and cooling fan in the duct shield, realizes radiating effect, and it is simple in structure, and production technology is convenient.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done detailed description:
See also Fig. 1, the ventilation heat abstractor of a kind of high-power components that the utility model discloses comprises duct shield 1, cabinet 5, power component fin 2 and cooling fan 3.
Duct shield 1 is installed in the cabinet 5, and power component fin 2 is installed in the duct shield 1 with cooling fan 3 successively, and cooling fan 3 is positioned at power component fin 2 belows.Cooling fan 3 is preferably axial flow blower, can certainly be other blower fan.
For the ease of installing, can be provided with mounting panel 4 in the cabinet 5, duct shield 1 is fixed on the mounting panel 4, and duct shield 1 stably is fixed on the mounting panel 4.
Duct shield 1 lower end is provided with air inlet 11, and in order to let more cold wind get in the duct shield 1, the air inlet 11 of duct shield 1 is set to " horn mouth " type.Duct shield 1 upper end sets out air port 12, and air outlet 12 is positioned at the top of cabinet 5, and relative with the opening 51 of cabinet 5.
In order to accelerate the wind speed in the heat dissipation wind channel, can between the air outlet 12 of the opening 51 of cabinet 5 and duct shield 1, air exhauster 6 be set.
Power component fin 2 is generally more than two and two; Concrete number is by the application decision of electrical panel cabinet; For strengthening radiating effect; Cooling fan 3 is corresponding one by one with power component fin 2, and promptly power component fin 2 correspondences are provided with a cooling fan 3, and the number of cooling fan 3 is corresponding with power component fin 2.
The utility model all places power component fin 2 and cooling fan 3 in the duct shield 1; Cold wind is got into by the air inlet 11 of duct shield 1; By the wind speed in the cooling fan 3 acceleration duct shields 1, thereby the heat exchange wind speed and the air quantity of increase power component fin 2 are realized after the heat exchange; The air exhauster 6 at opening 51 places through cabinet 5 is discharged hot blast outside the electrical panel cabinet, and radiating effect significantly improves.
The embodiment that the above is merely the utility model is not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection range of this case.
