Abstract
The utility model discloses a flameproof variable frequency speed regulation device capable of improving safety. The device comprises a shell and a cooling device. Accommodation space is formed in the lower part of the shell. The cooling device is positioned in the accommodation space. The cooling device is completely covered by the shell in a vertical direction. The prior art can be adopted for the circuit principle and structure of the variable frequency speed regulation device, and improvement in the shell and the position of the cooling device is focused, so that the running safety of the cooling device is improved, and the safety running of the variable frequency speed regulation device is ensured.
Description
Technical field
The utility model relates to a kind of flame proof electrical equipment, relates in particular to a kind of flame proof RHVC.
Background technology
Existing RHVC generally comprises housing, is provided with frequency converter (also claiming the frequency conversion movement) and auxiliary circuit in the housing, also is provided with cooling device in order to dispel the heat.
Existing most cooling device such as heat exchanger and blower fan expose in outside; In the harsh occasion of some execution conditions; Often have the damage that the thing that drops causes blower fan or heat exchanger; Severe patient causes cooling device to lose efficacy, and causes the damage of overheated shutdown of RHVC or element, has bigger potential safety hazard.
The utility model content
The utility model provides a kind of RHVC, and the position of its housing and cooling device is improved, and has improved the fail safe of cooling device operation, has guaranteed the safe operation of RHVC.
A kind of flame proof RHVC that improves fail safe comprises housing and cooling device, and described lower housing portion has spatial accommodation, and described cooling device is positioned at this spatial accommodation, and in the vertical direction, and described cooling device is covered by housing fully.
Described vertical direction, when referring generally to the flame proof RHVC and being in normal operating condition, because cooling device is covered by housing fully, the object that therefore vertically falls can directly not fallen on the cooling device, has improved fail safe.
Described cooling device includes but not limited to blower fan and heat exchanger.
As preferably, on the horizontal direction, described housing surrounds one or two side of cooling device, is more conducive to heat radiation like this.
All can adopt prior art with regard to its circuit theory and structure in the utility model RHVC; The utility model emphasis improves the position of its housing and cooling device; Improve the fail safe of cooling device operation, guaranteed the safe operation of RHVC.
Description of drawings
Fig. 1 is the structural representation of the utility model RHVC;
Fig. 2 is the right view of RHVC among Fig. 1.
Embodiment
Referring to accompanying drawing, a kind of flame proof RHVC that improves fail safe of the utility model comprises housing 1 and cooling device, and cooling device comprises blower fan 2 and heat exchanger 3.
The circuit of RHVC adopts prior art, and housing 1 bottom has spatial accommodation, and blower fan 2 all is positioned at this spatial accommodation with heat exchanger 3, and in the vertical direction blower fan 2 is covered by housing with heat exchanger 3 fully.
On the horizontal direction, housing 1 surrounds a side (left surface among the figure) of cooling device, is more conducive to heat radiation like this.
Because blower fan 2 and heat exchanger 3 are covered by housing 1 fully, the object that therefore vertically falls can directly not fallen on blower fan 2 and the heat exchanger 3, but receives stopping of housing 1, has protected cooling device like this, has improved the fail safe of RHVC operation.
Claims (3)
1. a flame proof RHVC that improves fail safe comprises housing and cooling device, it is characterized in that; Described lower housing portion has spatial accommodation; Described cooling device is positioned at this spatial accommodation, and in the vertical direction, and described cooling device is covered by housing fully.
2. the flame proof RHVC of raising fail safe as claimed in claim 1 is characterized in that described cooling device comprises blower fan and heat exchanger.
3. according to claim 1 or claim 2 the flame proof RHVC of raising fail safe is characterized in that on the horizontal direction, described housing surrounds one or two side of cooling device.
