Description

fireplace cooling device

technical field

The utility model relates to an environment temperature regulating device, in particular to a heat dissipation device for a fireplace.

Background technique

Fireplaces, also known as heaters, as indoor heating equipment, are both a heating method and a culture in many countries and regions. The fireplace mainly burns firewood or compressed firewood. The temperature in the center of the fireplace can reach hundreds of degrees Celsius, and gradually weakens in a fan shape from the center to the periphery. The uneven temperature forms air convection, thereby heating. The heating power of the fireplace is far greater than that of various types of air conditioners and heaters. The radiated light and heat contain infrared rays that can sterilize and drive away moisture. While heating, it can adjust the indoor dry humidity, making people feel very warm and comfortable.

However, the hot air around the fireplace will only flow upwards without external force, convect with the air above, and will not spread around, so only the space close to the fireplace or above it can get a better heating effect. The temperature rise is slightly worse in the space area away from the fireplace.

For this reason, the Chinese utility model patent with the authorized announcement number of 203757851U discloses a "heating furnace cooling fan", which includes a heat conduction base, a thermoelectric power generation module, a power drive mechanism, and a heat sink. The thermoelectric power generation module is fixedly installed on the heat conduction base Between the seat and the heat sink, the heat sink is equipped with the power drive mechanism, the power drive mechanism is connected to the thermoelectric power generation module, and the power drive mechanism includes a DC motor and an axial fan blade; a heating device (such as a fireplace) The heat generated is transmitted to the thermoelectric power generation module through the heat conduction base, and the thermoelectric power generation module uses the temperature difference between its two surfaces to generate electricity by itself. The hot air is blown to the space area away from the heating device, which has the advantages of simple structure, convenient use, energy saving and environmental protection, and can improve the heating efficiency of the heating device.

However, the radiator fan of the heating furnace directly connects the motor to the heat sink, and the vibration during its operation will not only affect the assembly stability between itself and the heat sink, but also transmit the vibration to the heat sink, so that the gap between the heat conduction base and the heat sink , so that the connecting screws loosen, resulting in the assembly stability of the motor and the reduction of the fit between the thermoelectric power generation module and the heat conduction base and the heat sink, which affects the power generation effect; at the same time, the heat conduction seat and other parts of the structure are connected by screws, and installation needs Adjust the torque to make the components installed evenly. These are installed manually. It is difficult to make the torque of each screw equal by manual adjustment. The unevenness of the installation will also affect the fit between the thermoelectric power generation module and the heat transfer base and heat sink. , affecting power generation performance.
