Abstract
The utility model discloses a heat-dissipation device for a roof fan cowl and relates to the field of the ventilator equipment. The heat-dissipation device for the roof fan cowl comprises a body of a cowl (10), wherein a plurality of through grooves (11) are formed in a side wall (1) of the cowl (10); a louver (2) is fixed in each through groove (11); one end of each louver (2) is fixed on a left side wall of each through groove (11); and the other end of each louver (2) is fixed on a right side wall of each through groove (11). The heat-dissipation device can conduct heat dissipation on a fan quickly; the service life of the fan is prolonged; and the heat-dissipation device is simple in structure and convenient to manufacture.
Description
Technical field:
The utility model relates to the ventilation equipment field, more specifically to a kind of roof fan hood sink.
Background technique:
The blast cap sidewall of existing roof ventilator all is enclosed construction, and the amount of heat in its blower fan can't Quick diffusing, affects service life of fan.
The model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of roof fan hood sink is provided, and it can improve fan life fast with fan radiating, and simultaneously, it is simple in structure, and is easily manufactured.
Technology solution of the present utility model is as follows:
A kind of roof fan hood sink comprises blast cap, forms a plurality of grooves on the sidewall of described blast cap, is fixed with a blinds in each groove, and blinds one end is fixed on the groove left side wall, the other end is fixed on the right side wall of groove.
Described blinds and horizontal line are 30 °～45° angle.
Described a plurality of groove is the rectangular groove, and groove is arranged in four composing types on sidewall to align up and down.
Described blast cap is the aluminum blast cap.
The beneficial effects of the utility model are:
It so that the heat of blower fan can shed from sidewall, improves heat dissipation rate and radiating effect by form a plurality of grooves at sidewall; In each groove, be fixed with a blinds, so that rainwater can not flow in the blast cap, guarantee that the driver of the blower fan in the blast cap can be not impaired like this.
