Description

Technical Field

[0001] This utility model relates to an active heat dissipation graphene oven. Background Technology

[0002] In southern my country, people use wood-burning stoves for heating in winter. Existing wood-burning stoves generally use a passive heating method, which utilizes the heat radiated by the stove body, flue, and burner plate to warm the room. While this saves firewood, it results in a slow heating rate. For example, as described in "CN213453732 U, A Stove Core and a Heating and Cooking Stove Including the Stove Core," for some guesthouses, restaurants, and card rooms, the stove needs to be lit immediately upon arrival to warm the room, and turned off after guests leave. This also saves wood. However, because passive heating stoves heat up slowly, guests have to endure low room temperatures for extended periods, negatively impacting their experience. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an active heat dissipation graphene heater to solve the problem of slow heat dissipation speed of existing heaters.

[0004] To solve the above problems, the technical solution to be provided by this utility model is as follows:

[0005] An active heat dissipation graphene oven includes an oven body, a flue pipe, a grate, and an oven door. Multiple heat-conducting strips are welded and fixed to the outside of the oven body. A heat insulation pipe is wrapped around the heat-conducting strips. The upper and lower ends of the heat insulation pipe are fixedly connected to the oven body through a ring plate and a bent angle steel, respectively. An air inlet chamber is separated from the oven body by the bent angle steel. The air inlet chamber is connected to a fan through a first air inlet pipe. Multiple exhaust holes are opened at the upper end of the heat insulation pipe. A graphene thermally conductive coating is sprayed on the outside of the oven body and the heat-conducting strips.

[0006] The first air inlet pipe is connected to the furnace body through the second air inlet pipe, and the first valve is installed on the second air inlet pipe.

[0007] A second valve is installed on the exhaust pipe;

[0008] The outer sleeve of the heat insulation pipe has an elastic clamp for sealing the vent hole, and a handle is fixedly connected to one end of the elastic clamp;

[0009] An insulation layer is installed outside the insulation pipe.

[0010] The technical effect of this utility model is that the heat generated by the burning of firewood in the furnace is transferred to the furnace body and the heat-conducting strips. Then, the cold air blown out by the fan is heated by the heat-conducting strips and the furnace body and discharged from each exhaust hole, so that the hot air can quickly enter the room to raise the room temperature and improve the room temperature raising speed. In addition, the structure is simple and safe and convenient to use. Attached Figure Description

[0020] An active heat dissipation graphene furnace includes a furnace body 1, a flue pipe 7, an ash box, a grate, and a furnace door 2. Multiple heat-conducting strips 13 are welded and fixed to the outside of the furnace body 1. A heat-insulating pipe 3 is fitted over the heat-conducting strips 13, with a 2-5mm gap between the heat-conducting strips 13 and the inner wall of the heat-insulating pipe 3. The upper and lower ends of the heat-insulating pipe 3 are fixedly connected to the furnace body 1 via a ring plate 12 and a bent angle steel 14, respectively. An air inlet chamber is separated from the furnace body 1 by the bent angle steel 14. The air inlet chamber is connected to a fan 4 via a first air inlet pipe 9. Multiple rows of vent holes 6 are opened at the upper end of the heat insulation pipe 3. Each row of vent holes 6 is composed of multiple vent holes 6. Each vent hole 6 is located in the gap between two adjacent heat-conducting strips 13. A notch is opened on the heat insulation pipe 3. The furnace door 2 and the wood ash box are located in the notch. The gap between the notch of the heat insulation pipe 3 and the furnace body 1 is sealed by a folding plate. A graphene thermal conductive coating is sprayed on the outside of the furnace body 1 and the heat-conducting strips 13. The graphene thermal conductive coating has a good heat dissipation effect. The graphene coating formula is, for example, patent number "CN 105273540 B, A graphene heat dissipation coating and its preparation method and application".

[0021] The working process of this utility model is as follows: After firewood is thrown into the furnace body 1 and lit, the heat generated by the burning firewood is transferred to the furnace body 1 and the heat conduction strip 13. Then the fan 4 is turned on. The fan 4 blows out cold air, which is heated by the heat conduction strip 13 and the furnace body 1 and then discharged from the exhaust hole 6, so that the hot air can quickly enter the room to raise the temperature of the room.

[0022] The first air inlet pipe 9 is connected to the furnace body 1 through the second air inlet pipe 10, and a first valve 11 is installed on the second air inlet pipe 10. When in use, the first valve 11 can be opened to allow the blower 4 to blow out some cold air into the furnace body 1 to supply oxygen for burning firewood and improve the combustion efficiency of the firewood;

[0023] A second valve 8 is installed on the flue pipe 7. When it is necessary to extinguish the firewood in the furnace body 1, the first valve 11 and the second valve 8 can be closed to seal the furnace body 1, so that the firewood in the furnace body 1 can be extinguished quickly.

[0024] The heat insulation pipe 3 is fitted with an elastic clamp 5 to seal the exhaust port 6. One end of the elastic clamp 5 is fixedly connected to a handle. The elastic clamp 5 is made of bent spring steel sheet. By moving the elastic clamp 5 up and down, the exhaust ports 6 are sealed, thereby adjusting the air volume of the exhaust ports 6.

[0025] An insulation layer is provided outside the insulation pipe 3. The insulation layer is a graphene EPS fireproof insulation board wrapped around the insulation pipe 3. The insulation layer can prevent people from being burned by the furnace body 1.
