Description

Combustion device with heat dissipation effect

The present invention mainly discloses a combustion device, especially a combustion device with heat dissipation effect.

The decorative flame fireplace device is not only a simple heating function, but also a decoration and atmosphere creation. Traditional indoor burning fireplaces will produce smoke or incomplete combustion due to restricted combustion in the semi-closed space of the house. Therefore, it is necessary to have a chimney configuration to force the indoor air to ventilate and convect. Due to the configuration of the chimney, the heating fireplace can be heated for a long time and a lot. In recent years, the direct vent gas fireplace has been invented. The air intake and exhaust are all outdoors, coupled with complete regulations and safer peripherals, making direct vent fireplaces the mainstream of large fireplaces. But for places where chimneys cannot be used, such as apartment buildings or where there is no fixed heating and air conditioning configuration, chimneyless fireplaces can only be used to install fireplaces. Therefore, in recent years, chimneyless fireplaces that have a small combustion scale but emphasize high efficiency and do not require chimney configuration have gradually become popular and occupy a certain market.

Chimneyless fireplaces often use gas or biomass fuels as fuel. The main reasons that biomass fuel fireplaces can be favored by consumers are the low cost of the installation, easy installation, and easy access to fuel. Environmental factors are also one of the key considerations. Therefore, the new types of biomass fuel fireplaces that have appeared in recent years include portable burning devices for indoor and outdoor use. The volume and combustion scale of this type of product are relatively large, and not only require heating It has a warm effect, but also has the appearance design, flame aesthetics and convenience. However, due to the simple structure of this type of product, the device often generates high temperatures. When the flame burns, heating the surrounding air will cause the air to rise and form convection with the surrounding air, so most of the heat will flow above the flame in the form of thermal convection, and the surrounding air will be heated. After that, most of the heat is transferred upward and dissipated. Only a small part of the heat is transferred to the horizontal side and below of the burning flame by means of radiation and conduction. If used for a long time indoors, the upward or backward heat may also cause the interior decoration to be exposed to high temperatures. damage.

In order to solve the problem of high temperature on the surface of the decorative flame device during combustion, especially under long-term use, due to the accumulation of heat, if the volume of the combustion space of the device is too small, the surface temperature is difficult to reduce to the level that the user can safely touch. The general solution can only increase the volume with the use of insulating materials to reduce the surface temperature of the device, but such a solution often causes the device to be too large, resulting in the disadvantage that the visual size of the flame does not match the device ratio. There are great difficulties in actual design.

In view of the lack of the above-mentioned conventional structure, the present inventor is dedicated to designing a combustion device with heat dissipation effect. By controlling multiple channels to generate cooling convection, it can provide a better heat dissipation method, which can greatly reduce the combustion space volume of the device. limits. Even under long-term use, the surface temperature can be maintained at a level that is safe for the user to touch. At the same time, the internal back plate is used to isolate the high temperature, and at the same time, the heat is transferred forward in a horizontal manner by radiation, which greatly improves the usability and thermal efficiency. Overcome all the shortcomings of the above-mentioned conventional structure.
