Abstract
The utility model discloses a heat sink in lamp cap body capable of leading the inner cavity of the lamp cap body to effectively radiate heat, which comprises the lamp cap body; the lamp cap body consists of a top cap, a middle shell and a base; the middle shell is provided with a luminescent device and a power device providing energies to the luminescent device; the lamp cap body is also provided with a radiating aluminum pipe; the cut at the upper end of the radiating aluminum pipe is communicated with the inner cavity of the top cap; the cut at the lower end of the radiating aluminum pipe is communicated with the cut at the lower end of the base; a clearance which prevents rains and ventilates is arranged between the top cap and the middle shell. The heat sink in lamp cap body of the structure has the advantages of leading the inner cavity of the lamp cap body to effectively radiate heat, and improving the service life of traffic lights.
Description
Technical field
The utility model relates to the body that is used for traffic lights, relates in particular to the heat abstractor in a kind of body.
Background technology
When the city has a power failure; usually can use portable traffic lights to direct traffic; this traffic lights; be by body; body is made up of top cover, middle casing and base; connecting rod and base constitute, luminescent device is installed in the body and provides the power device of energy to luminescent device, the storage battery operated by rotary motion in base as total energy.In order to prevent the erosion of rainwater, body is made into enclosed construction, but the shortcoming that this enclosed construction exists is: after being subjected to long-time solar light irradiation, temperature in the body is higher, add the heat that power device itself distributes, cause the circuit elements components from being damaged easily, influence the service life of traffic lights.
The utility model content
Technical problem to be solved in the utility model is: the heat abstractor in a kind of body that can make body inner chamber efficiently radiates heat is provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the heat abstractor in the body, comprise: body, body is made up of top cover, middle casing and base, be provided with luminescent device in the middle casing and the power device of energy is provided to luminescent device, in described body, also be provided with the heat radiation aluminum pipe, the upper end open of heat radiation aluminum pipe communicates with the top cover inner chamber, the lower ending opening of heat radiation aluminum pipe communicates with the lower ending opening of base, is provided with rainproof ventilative gap between top cover and middle casing.
In order to solve the problems of the technologies described above better, the further technical scheme of the utility model is: described power device is installed on the heat radiation aluminum pipe.
In order to solve the problems of the technologies described above better, the further technical scheme of the utility model is: described body is spherical in shape.
The utility model has the advantages that: the heat abstractor in the body of this structure can make body inner chamber efficiently radiates heat, improves the service life of traffic lights.
Description of drawings
Fig. 1 is the structural representation of the heat abstractor in the utility model body.
Among the figure: 1, top cover, 11, the top cover cavity, 2, middle casing, 21, luminescent device, 22, power device, 3, base, 31, the lower ending opening of base, 4, the heat radiation aluminum pipe, 41, the upper end open of heat radiation on the aluminum pipe, 42, the lower ending opening of heat radiation aluminum pipe, 5, the gap.
The specific embodiment
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1, heat abstractor in the body, comprise: body spherical in shape, body is made up of top cover 1, middle casing 2 and base 3, be provided with luminescent device 21 in the middle casing 2 and the power device 22 of energy be provided for luminescent device 21, in body, also be provided with heat radiation aluminum pipe 4, power device 22 is installed on the heat radiation aluminum pipe 4, the upper end open 41 of heat radiation aluminum pipe 4 communicates with top cover inner chamber 11, the lower ending opening 42 of heat radiation aluminum pipe 4 communicates with the lower ending opening 31 of base 3, is provided with rainproof ventilative gap 5 between top cover 1 and middle casing 2.
As shown in Figure 1, the operation principle of the heat abstractor in the body of this structure is: after body is subjected to long-time solar light irradiation, temperature in the body can raise gradually, add the heat that power device 22 itself distributes, will cause the temperature in the body too high, thereby in body, produce high-temperature gas, the lower ending opening 31 of high-temperature gas by base 3 enters in heat radiation aluminum pipe 4 that is interconnected with it, and then by the heat radiation aluminum pipe 4 upper end open 41 enter into the top cover inner chamber 11 that is interconnected with it, between top cover 1 and middle casing 2, be provided with at last the rainproof ventilative gap 5 and discharge, thereby realization is to the heat radiation of body.
Claims (3)
1, the heat abstractor in the body, comprise: body, body is made up of top cover, middle casing and base, be provided with luminescent device in the middle casing and the power device of energy is provided to luminescent device, it is characterized in that: in described body, also be provided with the heat radiation aluminum pipe, the upper end open of heat radiation aluminum pipe communicates with the top cover inner chamber, and the lower ending opening of heat radiation aluminum pipe communicates with the lower ending opening of base, is provided with rainproof ventilative gap between top cover and middle casing.
2, the heat abstractor in the body according to claim 1 is characterized in that: described power device is installed on the heat radiation aluminum pipe.
