Description

Combustion device with heat radiation effect

Technical Field

The present invention relates to a combustion apparatus, and more particularly to a combustion apparatus with heat dissipation.

Background

The decorative flame fireplace device not only has a simple heating function, but also has decoration and atmosphere creation functions. The conventional indoor combustion fireplace has the problem that smoke is generated or combustion is incomplete in a semi-closed space of a house due to limited combustion, so that a chimney is required to be arranged to force indoor air to exchange air and convect. The heating fireplace is capable of long-term and large-scale heating due to the configuration of the chimney. In recent years, the gas fireplace with direct vent has the advantages that air intake and exhaust are both from the outside, and complete regulations and safer peripheral devices are added, so that the direct vent fireplace becomes the mainstream of a large fireplace. However, for places where chimneys cannot be used originally, such as apartment buildings or where fixed heating and air conditioning arrangements are not available, the fireplace can only be installed without chimneys. Therefore, in recent years, the non-chimney fireplace with small burning scale, strong adjustment and high efficiency and without the chimney is gradually welcomed and has a certain market.

The fuel of the chimney-free fireplace is usually gas or biomass fuel, and the biomass fuel fireplace is favored by consumers mainly because the device is low in price, convenient to install and convenient to fuel, and the environmental protection factor is one of the important points of consideration. So that new biomass fuel fireplaces in recent years include indoor and outdoor portable combustion devices. The product has larger volume and combustion scale, not only gives consideration to the heating and warm-keeping effects, but also has appearance design, flame aesthetics and convenience. However, such products often cause the device to generate high temperature due to simple structure, and since the air rises and forms convection with the ambient air when the flame burns, most of the heat flows above the flame in a heat convection manner, most of the heat is transferred and dissipated upwards after the ambient air is heated, only a small part of the heat is transferred to the horizontal side and the lower side of the burning flame in a radiation and conduction manner, and if the device is used indoors for a long time, the indoor decoration may be damaged due to high temperature due to the upward or backward heat.

In order to solve the problem of high surface temperature of the decorative flame device caused by combustion, particularly under the condition of long-time use, the surface temperature of the decorative flame device is difficult to reduce to the extent that a user can feel safe if the volume of a combustion space of the device is too small due to heat accumulation. The general solution can only be to reduce the surface temperature of the device by increasing the volume and matching with the application of insulating materials, but such a solution often causes the defect that the volume of the device is too large, and the visual size of the flame is not matched with the proportion of the device. There are great difficulties in practical design.
