Detailed Description
The technical contents of the present utility model will be described in detail with reference to the accompanying drawings and specific examples.
As shown in fig. 1 to 4, the embodiment of the present utility model provides a fresh air fan with a heating function, which includes an electric heating box 100, a fresh air handling unit 200, and a connecting pipe 300 connecting the two. Wherein the electric heating box 100 is installed in the air duct outside the fresh air handling unit 200 and upstream of the fresh air inlet. As shown in fig. 4. The connection pipe 300 is made of a heat-insulating flexible material, and can be deformed according to installation conditions to adapt to various installation conditions.
Specifically, as shown in fig. 1 and 2, the electric heating box 100 includes a housing 1, a fixing bracket 2, a fin heater group 3, and a heating pipe 4.
The casing 1 includes a first side wall 11, a second side wall 12, a third side wall 13, a fourth side wall 14, a top plate 15, and a back plate 16, which are sequentially connected, and encloses a closed space. The first side wall is provided with a first ventilation opening 10. The third side wall 13 is provided with a second ventilation opening 20. The openings of the first ventilation opening 10 and the second ventilation opening 20 are designed in pairs. The second air vent 20 is sleeved on the fresh air vent of the fresh air handling unit 200 and is communicated with the fresh air handling unit 200.
Inside the casing 1, a heat insulating layer 6 is further provided, which is fixed inside the casing 1. Specifically, the heat insulating layer 6 is made of heat insulating fireproof material, and is fixed on the first side wall 11, the second side wall 12, the third side wall 13, the fourth side wall 14, the top plate 15 and the back plate 16 to form an enclosed space. This results in a significant reduction of the heat radiation.
The fixing brackets 2 are arranged at two ends of the fin heater group 3. One end of the fixing bracket 2 is fixed to the top plate 15 of the casing 1 by a rivet or the like, and the other end is fixed to the back plate 16 of the casing 1 by a rivet or the like. The fixing bracket 2 is used for fixing the fin heater group 3, so that the fin heater group 3 arranged on the bracket can be prevented from being deviated under the action of wind flow.
As shown in fig. 3, each fin in the fin heater group 3 is mounted on the fixing bracket 2 along the fresh air flowing direction, and is composed of 1 to 3 fin heaters mounted in parallel. The fin heater is composed of a plurality of heat radiating fins 31. The power lines at two ends of the fin heater group 3 are fixed on the fixed bracket 2 to be connected with an external power supply.
The heating pipe 4 is inserted into the mounting hole of the radiating fin 31, and the radiating fin is provided with a mounting hole which is matched with the heating pipe 4. The heat radiating fins 31 are disposed on the heating pipe 4 and equally spaced apart along the length direction of the heating pipe 4 such that a gap can be formed between the heating pipe 4 and the heat radiating fins 31 to allow the wind flow to pass through. Therefore, the fin is consistent with the flow direction of the fresh air, and the air quantity is not reduced.
In this embodiment, the second air vent 20 is sleeved on the connecting pipe 300 to connect with a fresh air port of a fresh air handling unit. The electric heating box arranged outside the fresh air unit 200 forms a fresh air channel through the sleeved second air vent 20 and the fresh air vent. When the outdoor temperature is lower than the indoor temperature, fresh air enters the electric heating box 100 from the first ventilation opening 10, exchanges heat with heat emitted by the fin heater group 3, and the fresh air temperature is increased. The new trend that the temperature risees passes through second ventilation opening 20 (new trend mouth) and gets into indoor along the new trend passageway, has effectively promoted indoor air temperature, practices thrift the energy consumption.
The fresh air handling unit 200 in the embodiment of the present utility model may be various heat exchange fresh air handling units, which are not particularly limited herein.
In summary, the electric heating box is additionally arranged on the outer side of the fresh air port of the fresh air unit, so that the aim of improving the air supply temperature can be fulfilled. Specifically, the fresh air entering the fresh air unit is heated by the fin heater in the electric heating box, then enters the fresh air unit through the fresh air port and is sent into a room along the fresh air channel. The novel air supply device is simple in structure, is easy to refit an existing fresh air unit, and effectively improves air supply effect.
In addition, the electric heating box is designed to be connected with the fresh air handling unit 200 through the connecting pipe 300 and is independent of the fresh air handling unit 200, so that the flexibility of space installation is improved, and the electric heating box is suitable for various installation working conditions. In addition, the electric heating box is insulated by the insulating material, so that people can be prevented from being scalded.
