Description

Heat radiation cigarette cap

Technical Field

The utility model relates to a metal building material, in particular to a cigarette cap.

Background

The chimney cap is a metal building material connected to the top of the chimney and used for keeping off rain for the chimney. The smoke cap in the prior art is not improved aiming at the heat dissipation effect, some heat supply equipment supplies heat through a chimney, and if the chimney of the heat supply equipment adopts the smoke cap capable of enhancing the heat dissipation, the heat exchange efficiency can be improved; some cooling devices for cooling high temperature equipment utilize chimneys to exchange heat with the atmosphere, and if these cooling devices employ hoods that enhance heat dissipation, the cooling performance of the cooling device will be further enhanced.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a cigarette cap which can enhance the heat dissipation.

The utility model provides a technical scheme that its technical problem adopted is:

the heat dissipation cigarette cap comprises a shade positioned at the top and a sleeve used for being connected with a chimney, wherein annular shutters are arranged between the sleeve and the shade, at least three supporting rods in a circumferential array are arranged on the sleeve, the shade and the shutters depend on the supporting rods to be fixed, and the shutters are composed of a plurality of annular cooling fins.

Preferably, the axial cross section of the heat dissipation fin is in a zigzag shape, and the upper end of the heat dissipation fin at the lower position is hidden in the lower end of the heat dissipation fin at the upper position.

Preferably, the radius of the shroud is greater than the radius of the heat sink.

Preferably, all the struts are fixedly connected with the inner ring of the heat sink.

Preferably, the upper part of the sleeve narrows from bottom to top piece by piece, and the radius of the narrowest part at the top end is equal to the radius of the inner ring of the radiating fin.

Preferably, the lower part of the sleeve is provided with a wave-shaped bayonet.

The utility model has the advantages that: the utility model discloses a cigarette cap is provided with annular fin between shade and sleeve, connects the back on the chimney, and the cigarette looses from between the fin, and the fin is existing to keep off the rain, prevents that the effect of natural wind from flowing into the chimney, also can increase the heat radiating area of cigarette cap, has improved the heat exchange capacity of cigarette cap, very is applicable to the heating equipment or the cooling device of taking the chimney.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a perspective view of the present invention;

fig. 2 is a front view of the present invention;

fig. 3 is an axial cross-sectional view of the present invention.

Detailed Description

Referring to fig. 1, the heat dissipation cigarette cap comprises a shade 2 positioned at the top and a sleeve 1 used for being connected with a chimney, wherein an annular louver 4 is arranged between the sleeve 1 and the shade 2, at least three supporting rods 3 in a circumferential array are arranged on the sleeve 1, the shade 2 and the louver 4 are fixed by the supporting rods 3, and the louver 4 is composed of a plurality of annular cooling fins.

The heat dissipation cigarette cap is made of metal plates, three support rods 3 are preferred, and excessive support rods can affect the air outlet of the cigarette cap.

Referring to fig. 2 and 3, the axial cross-section of the fin is in the shape of an elongated "Z", and the upper end of the lower fin is hidden inside the lower end of the upper fin. Such fin can enough prevent that the rainwater slant from blowing in the cigarette hat, can prevent again that natural wind from blowing in the chimney backward, simultaneously, has increased the area of contact of fin and air, provides good radiating effect for the cigarette hat.

Preferably, the radius of the shroud 2 is greater than the radius of the heat sink. The shade 2 is an arc plate protruding upwards, no water is stored outside, and the smoke is guided to be sprayed out from the radiating fins.

The support rods 3 can be arranged on the periphery or the inner circle of the radiating fin and can also penetrate through the radiating fin. All the support rods 3 are fixedly connected with the inner ring of the radiating fin to be the best in appearance, and the cigarette cap is the most convenient to assemble or weld.

The upper part of the sleeve 1 narrows from bottom to top piece by piece, and the radius of the narrowest part at the top end is equal to the radius of the inner ring of the radiating fin. The flow velocity can be accelerated by narrowing the caliber, and the larger the flow velocity is, the higher the heat exchange efficiency is.

The lower part of the sleeve 1 is provided with a wave-shaped bayonet. When in installation, the chimney is directly sleeved on a common chimney; or, also be provided with corresponding wave bayonet socket on the chimney, install and push down this cigarette cap often, swift chucking, for convenient the sheathe in, two three little snips can be opened to telescopic minimum.

The annular radiating fins are arranged between the shade and the sleeve, smoke or gas is sprayed out from the radiating fins after the annular radiating fins are connected to a chimney, the radiating fins have the functions of keeping out rain and preventing natural wind from flowing backwards into the chimney, the radiating area of the chimney cap can be enlarged, the heat exchange capacity of the chimney cap is improved, the chimney cap is very suitable for heating equipment or a cooling device with the chimney, and when the chimney cap is used for the chimney of the heating equipment, the heat exchange efficiency can be improved, and the temperature rise of a place needing to be heated is accelerated; when the cooling device is used for cooling a cooling device of high-temperature equipment, the radiating smoke cap can be enhanced, the cooling performance of the cooling device can be further improved, and heat-labile elements are protected.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and decorations can be made without departing from the principle of the invention, and these modifications and decorations are also regarded as the protection scope of the present invention.
