Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to the structure of a fan heater. Background Art

[0002] Existing air heaters lack internal cooling modules and therefore only produce natural air. During the hot summer months, with high ambient temperatures and high humidity, natural air is no longer sufficient to cool down. Only air conditioning systems with cooling functions can provide a sense of coolness. However, since air conditioning systems cool the entire room, they consume a lot of electricity, which is not conducive to energy conservation and environmental protection. Therefore, the idea is to add a semiconductor cooling module to the air heater to provide cooling functionality. Compared to air conditioning systems with power consumption exceeding 2000W, air heaters and coolers equipped with semiconductor cooling modules consume only around 150W, allowing users to enjoy cool air while also contributing to energy conservation and environmental protection.

[0013] Preferably, the thermal insulation layer is made of polystyrene foam board.

[0014] Furthermore, the heat absorbing sheet includes a first fin arranged horizontally.

[0035] The air duct assembly 2 connects the first air inlet 11 and the first air outlet 12 to form a first fluid channel 7 .

[0036] The housing 1 and the air duct assembly 2 form a second fluid channel 8 .

[0037] The second fluid channel 8 connects the second air inlet 13 , the second air outlet 14 and the heat dissipation port 15 .

[0038] The heating component 3 is disposed at the first air outlet 12 .

[0039] The first fan assembly 4 is disposed in the first fluid channel 7 .

[0040] The second fan assembly 4 is disposed in the second fluid channel 8 .

[0042] The refrigeration assembly 5 further includes an insulation layer 54. The insulation layer 54 is disposed between the heat absorbing fin 52 and the heat sink 53. The insulation layer 54 serves to reduce heat exchange between the heat absorbing fin 52 and the heat sink 53. The insulation layer 54 is made of polystyrene foam board, which provides excellent thermal insulation.

[0043] The heat absorbing sheet 52 includes first fins 521 arranged horizontally.

[0044] The heat sink 53 includes second fins 531 arranged horizontally.

[0045] The housing 1 includes a slot 16. The heat dissipation vent 15 is provided on the side of the slot 16. The function of the heat dissipation vent 15 is to dissipate the heat accumulated on the upper portion of the housing 1 during operation to the outside of the housing 1 through natural convection.

[0046] The second fan assembly 6 is disposed at the second air outlet 14 .

[0047] When the second fan assembly 6 uses a 12V 3200RPM 60*60*10mm DC fan, it can provide sufficient heat dissipation capacity for the 120W semiconductor cooling chip 51.

[0050] When the hot air blower operates in hot air mode, the heating component 3 and the first fan component 4 are activated. Driven by the motor 42, the perfusion blades 41 in the first fluid channel 7 generate airflow toward the heating component 3. The airflow passes through the heating component 3 and becomes hot air.

[0051] When the hot / cold air blower operates in cold air mode, the first fan assembly 4, cooling assembly 5, and second fan assembly 6 are activated. The semiconductor cooling fin 51 absorbs heat at the cold end 511 and releases heat at the hot end 512. The heat absorbing fin 52 cools down at the cold end 511. The airflow toward the heat absorbing fin 52 becomes cold air after passing through the cooler fin 52. Simultaneously, the second fan assembly 6 dissipates heat from the heat sink 53 in the second fluid channel 8.
