Abstract

The utility model relates to an infrared dome radiating system, which consists of an external circulative air duct cooling system and a dome internal radiating system. The external circulative air duct cooling system comprises a circulating passage formed by an exhaust fan on the upper portion of a U-shaped frame, an air duct cabin linked with an inlet of the exhaust fan, and a gap between an inner cover and an outer cover. The internal radiating system comprises a sealed circulative air duct formed by a dome cavity, a vertical axial central through hole and an inner cover cavity. Heat exchange of the infrared dome radiating system is completed by means of air flowing in the air duct cabin and the gap between the inner cover and the outer cover, while heat exchange of the infrared dome radiating system is further completed by means of the air duct formed by the dome, the vertical axial central through hole and the inner cover cavity, and thereby surface area of the dome for radiating to the outside is increased, radiating efficacy of the dome is improved, temperature of the dome is effectively reduced, and the service lives of the dome and an infrared lamp are prolonged.

Description

Infrared ball cooling system

Technical field

The utility model relates to the safety monitoring technical field, relates to a kind of infrared ball cooling system.

Background technology

A kind of intelligent video camera front end of infrared ball, full name is infrared ball-shaped camera, and perhaps integrated infrared ball perhaps is called for short infrared ball.Infrared ball-shaped camera be supervisory system the most complicated with the best video camera front end of general performance effect, can adapt to high density, the monitoring occasion of complicacy.The cooling of existing infrared spherical camera relies on self-radiating usually, and the ball machine is little to the surface area of external world's heat radiation, and the heat dissipation of ball machine is low, and is too high like the operating ambient temperature of ball machine, can reduce the serviceable life of ball machine and infrared lamp.

Therefore, how to address this problem with regard to the technician that becomes the present technique field the problem that will study and solve.

Summary of the invention

The purpose of the utility model is exactly the deficiency that exists to existing design; A kind of new ball machine architecture advances scheme is provided; Promptly design a kind of infrared ball cooling system; Carry the ball lifter radiating efficiency, make infrared ball-shaped camera be operated in the serviceable life that the higher occasion of environment temperature can not influence ball machine and infrared lamp yet.

The utility model is to realize through such technical scheme: infrared ball cooling system is characterized in that system is made up of outer circulation wind path cooling system and the spheroid internal heat dissipating system that infrared ball outer cover, inner cover, U type frame and spheroid constitute;

Said outer circulation wind path cooling system forms circulation passage by the gap between the exhaust fan on U type frame top, cabin, the air channel body that is connected with the exhaust fan import and inner cover, outer cover;

Said built-in cooling system forms the sealing circulation air path by spheroid die cavity, Z-axis central through hole, inner cover die cavity;

Spheroid is joined frame itself and is designed to band shape heat radiating fin structure; Annular fin is distributed in the outside that spheroid is joined the last lower surface camber of frame; Join the frame heat radiation spigot surface that is connected with spheroid and be distributed in spheroid and join four jiaos of frame cross section, four jiaos of the heat radiation spigot surface are processed with screw, are used for fastening infrared lamp plate; There is the radiating surface that is processed with screw hole column the front of spheroid back cover, makes spheroid back cover and spheroid join frame through the radiating surface screw hole column and is fastenedly connected with screw.

When the ball machine was worked, infrared lamp was opened, and temperature rises; Fan begins to rotate, and follows the wind path start-up of cooling system outward: through fan fluid (air) is sucked from the inside and outside shell gap, through cabin, air channel body; Blow to spherome surface, quicken the speed of spherome surface fluid (air), form heat loss through convection.

Built-in cooling system heat radiation approach is divided into two parts, and first is transmitted to spheroid with the heat of infrared lamp plate through the heat radiation spigot surface to join the frame surface, fluid (air) the formation heat loss through convection that quickens through outer circulation wind path cooling system fan again; Another part is to form heat loss through convection through the temperature difference between spheroid, Z-axis central through hole, the inner cover die cavity.

The beneficial effect of the utility model is: infrared ball cooling system is through cabin, air channel body and inner cover and the mobile exchange heat of carrying out of outer cover clearance air; And the wind path of forming through spheroid, Z-axis central through hole and inner cover die cavity carries out heat interchange; Increased the surface area of ball machine to external world's heat radiation; Improve the heat dissipation of ball machine, effectively reduced the temperature of ball machine, prolonged the serviceable life of ball machine and infrared lamp.
