Description

Thermal insulation device

The invention relates to a heat preservation device, in particular to a heat preservation device which uses a heat exchange conduit to heat air and has both environmental protection and safety.

Conventional thermal insulation devices, such as animal warmers, mostly achieve thermal insulation by means of thermal radiation. For example, thermal energy is generated by bulb irradiation, or heat is generated by mixing gas and air. However, the method of using the bulb to illuminate requires a large amount of electric power, which wastes energy and is not environmentally friendly. If the gas-type warmer is hit by an external force or a strong wind, it is easy to stop the operation, and the gas is not completely burned or the gas is leaked. Causes chickens, ducks, pigs and other animals to be poisoned by gas poisoning.

In view of this, the main object of the present invention is to provide an energy-saving, environmentally-friendly and safe thermal insulation device.

In order to achieve the foregoing, an insulation device provided by the present invention mainly comprises a cover, a fan and a heat exchange conduit. The cover has an accommodating space and an opening communicating with the accommodating space; the fan is disposed in the accommodating space of the cover, and the fan is configured to generate a forced airflow through the opening of the cover; the heat The exchange conduit is disposed in the accommodating space of the cover and is located in a flow path of the forced air flow, and the heat exchange conduit has a fluid inlet and a fluid outlet. Thereby, the heat preservation device of the present invention can use the heat exchange conduit to heat the cold air to hot air, and then the fan drives the hot air to be sent out through the opening to achieve the purpose of heat preservation. Since the fluid in the heat exchange conduit can be heated by solar energy, the thermal insulation device of the present invention is not only energy-saving and carbon-saving but also extremely safe.

In the thermal insulation device provided by the present invention, a heat dissipation fin set may be further disposed on an outer wall surface of the heat exchange conduit. Thereby, the heat dissipation fin group can bring out the heat energy of the fluid in the heat exchange conduit and increase the contact area with the cold air, thereby improving the efficiency of heating the cold air.

In addition, in the heat preservation device according to a preferred embodiment of the present invention, the heat exchange conduit can be divided into a front portion having the fluid inlet, a rear portion having the fluid outlet, and a front and a rear portion connected thereto. The middle section of the fan, and the middle section is continuously bent. By increasing the contact area of the heat exchange conduit with the cold air, the efficiency of heating the cold air is enhanced.

In the thermal insulation device provided by the present invention, the cover body may have a skirt that faces outward and is tapered toward the inside. Thereby, when the fan drives the hot air to circulate, and the hot air is moved along the inner wall surface of the cover body and is sent out from the opening, the skirt can concentrate the hot air under the cover body to improve the heat preservation effect.

Thereby, the heat dissipation fin set 50 can bring out the heat energy of the fluid in the heat exchange conduit 40, and can increase the contact area with the cold air to improve the efficiency of heating the cold air.

Referring to the fourth figure, when the heat preservation device 10 of the present invention is applied to raising chickens, the heat preservation device 10 can be hung over the captivity range of the chicken. In this embodiment, the fan 30 is wound around the cover. The central axis of the body 20 rotates counterclockwise, so the first tuyere 31 is an air outlet, and the second tuyere 33 is an air outlet. In operation, the high temperature flow system is continuously injected from the fluid inlet 411 of the heat exchange conduit 40 and fills the heat exchange conduit middle section 45, and the fan 30 draws the cold air A _c around the cover 20 into the first tuyere 31, and then after the second air outlet 33 blowing cold air a _c, from the second cool air blown tuyere 33 a _c by heat exchange catheter 40 and the heat dissipating fins 50, the heat exchange catheter 40 will be the fin assembly 50 and carried The heat energy is heated to the hot air A _h and discharged through the opening 24 to achieve the purpose of keeping the chicks warm, and the fluid whose temperature gradually decreases in the heat exchange conduit 40 can be discharged through the fluid outlet 431, and the fluid can pass through the solar collector. The fluid inlet 411 is injected and thus circulated continuously to maintain the temperature of the heat exchange conduit section 45.

Alternatively, as shown in FIG. 5, when the fan 30 rotates clockwise around the central axis of the cover 20, the first tuyere 31 is an air outlet, and the second tuyere 33 is an air outlet. In operation, the high temperature fluid is also injected from the fluid inlet 411 of the heat exchange conduit 40 and fills the heat exchange conduit midsection 45, while the cold air A _c below the enclosure 20 is attracted by the suction of the second tuyer 33 of the fan 30. And passing through the heat exchange conduit 40 and the heat dissipation fin set 50. At this time, the cold air A _c has been heated by the heat exchange conduit 40 and the heat dissipation fin 50 to heat the air A _h and is sucked into the fan 30 The tuyere 33, after which the hot air A _h blown by the first tuyere 31 is discharged along the inner wall surface 23 of the cover 20 from the heat retaining device 10 to the area where the chicks are housed (that is, under the heat exchange conduit 40) The purpose of the chick. It should be particularly noted that, in the present embodiment, the cover 20 has a skirt 25 extending downward and facing inward so that the hot air _Ah can be concentratedly discharged to the area where the chicks are housed.

In addition, although the foregoing embodiments all have the heat sink fin set 50 set to heat Exchanging the outer wall surface of the duct 40, but the heat radiating fin group 50 is mainly used to bring out the heat energy of the fluid in the heat exchange duct 40, and at the same time increase the contact area with the cold air, and improve the performance of heating the cold air, therefore, the present invention The heat insulating device 10 can achieve the purpose of heat insulation even if the heat sink fin group 50 is not provided.
