Abstract
The utility model discloses a heat radiator of an electrical control box, comprising a heat vent arranged on an electrical control box body, a cover plate and a limit mechanism; the cover plate is rotatably connected to the position of the heat vent on the box body to optionally open or close the heat vent; the limit mechanism is used for limiting the rotation angle of the cover plate; by rotating the cover plate, the heat vents can be opened and closed, and the rotation angle of the cover plate is positioned by the limit mechanism; when being used at the project sites, the heat vent can be closed to prevent dust from entering in the electrical control box so that electrical elements can be protected; when in normal work, the heat vent can be opened to ventilate and radiate heat; compared with prior art, the heat radiator of the electrical control box is simple in structure, convenient and reliable in operation.
Description
Technical field
The utility model relates to the control appliance of air-conditioning, especially a kind of heat abstractor of air-conditioning electric cabinet.
Background technology
Offer thermovent on the casing of the commercial air-conditioning electric cabinet of the overwhelming majority, so that the electric elements in the electric cabinet are dispelled the heat.But, because when installation initial stage of business air conditioner (when machine does not also come into operation) or market finishing, a large amount of dusts that the installation site produces can enter into electric cabinet by the thermovent on the electric cabinet, directly have influence on the later operate as normal of electric elements.In order to address the above problem the measure of taking at present be: the venetian blind type opening and closing device is installed at the thermovent place, and the venetian blind type opening and closing device that has is by electronic control, and the problem that this opening and closing device exists is: (1) complex structure, cost height; (2) take up room greatly, influence the layout of electric elements in the electric cabinet; (3) owing to also energising of engineering place in most cases, opening and closing device can't be operated, so practicality is not strong.
Summary of the invention
The purpose of this utility model is, a kind of heat abstractor of easy and simple to handle, reliable electric cabinet is provided.
The heat abstractor of a kind of electric cabinet of the present utility model, comprise the thermovent that is located on the electric cabinet casing, also comprise cover plate and position-limit mechanism, this cover plate is rotatably connected on the described casing at described thermovent place, optionally to open or close described thermovent, described position-limit mechanism is used for carrying out spacing to the rotational angle of described cover plate.
Preferably, be fixed with bearing pin on described cover plate, offer the axis hole that matches with this bearing pin on described casing, described cover plate is connected with this axis hole by this bearing pin rotationally with described casing.
Preferably, described cover plate is positioned at described casing, and an end of described bearing pin is connected with this cover plate, and the other end stretches out and knob is housed from described axis hole.
Preferably, described position-limit mechanism comprises chute and the traveller that matches, this chute is located on the described casing, and this chute has the primary importance and the second place, and this traveller is positioned at described chute, and fixedlys connected with described cover plate directly or indirectly, when this traveller is positioned at described primary importance, described cover plate is closed described thermovent, and when this traveller was positioned at the described second place, described cover plate was opened described thermovent.
Preferably, described thermovent is a plurality of, and these a plurality of thermovents are that the center is provided with at interval along circumferential with the tie point of described cover plate and described casing, and described cover plate is circular, is provided with on this cover plate and a plurality of one to one through holes of described a plurality of thermovents.
The heat abstractor of electric cabinet of the present utility model drives cover plate by the rotation external knob and rotates, and plays the effect that opens and closes thermovent, and the rotational angle of cover plate comes spacing by position-limit mechanism.When building, shut thermovent, can prevent that dust from entering into electric cabinet, the protection electric elements in the engineering place; During operate as normal, open thermovent, play the effect of ventilation and heat.Compared with prior art, the utlity model has advantage simple in structure, easy and simple to handle, reliable.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figures 1 to 3, the heat abstractor of electric cabinet is made up of the thermovent 11 on the casing 1 that is located at electric cabinet, cover plate 2 and position-limit mechanism, and wherein, thermovent 11 has two groups, and these two groups of thermovents 11 are arranged above and below.Every group of thermovent 11 all comprises a plurality of thermovents 11, and these a plurality of thermovents 11 are provided with axis hole (not shown on the figure) along circumferentially being provided with at interval in the centre of these a plurality of thermovents 11.
The rotational angle of cover plate 2 is undertaken spacing by position-limit mechanism.Position-limit mechanism mainly is made up of chute 12 that matches and traveller 5, and this chute 12 is located on the casing 1, and this chute 12 has the primary importance and the second place.Traveller 5 is positioned at chute 12, and fixedlys connected with bearing pin 6 through connector 3.When traveller 5 was positioned at primary importance, cover plate 2 was closed thermovent 11 (state of one group of thermovent below among Fig. 1), and when traveller 5 was positioned at the second place, cover plate 2 was opened thermovent 11 (state of one group of thermovent above among Fig. 1).
Only be specific embodiment of the utility model below, do not limit protection range of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection range of the present utility model.
