Problems solved by technology

[0002] The burner, especially the premixed burner, is mainly installed in the combustion chamber of the heat exchanger, and the heat energy generated by the combustion of the burner is exchanged with the heat exchange body in the heat exchanger; the combustion of the burner currently on the market The total porosity on the layer is generally about 12%, because when the porosity on the combustion layer is too large, the heat intensity on the surface of the burner will be too large, resulting in abnormal problems such as high temperature, tempering, and deformation of the burner. Ensuring the combustion intensity of the burner, thereby increasing the volume or height of the burner is a common method, which leads to an increase in the volume of the heat exchanger, and there is room for improvement

Embodiment 1

[0037] A kind of burner with cooling device 2 of the present invention is as figure 1 and figure 2 As shown, the burner main body 1 is a cylindrical structure, including a combustion surface 12 and an end cover 13. The combustion surface 12 is a metal plate with a combustion hole 121, preferably made of stainless steel or copper. The metal plate of the hole 121 is closed and enclosed to form the cylinder wall of the burner body 1, forming the combustion layer 12 of the burner body 1, and the total porosity of the combustion holes 121 on the combustion layer 12 is 14% to 50%; the air flow The distributor 14 is arranged in the gas supply chamber 11. The structure of the airflow distributor 14 is adapted to the structure of the combustion level 12. It is a metal plate with an air outlet 141 and surrounds it to form a cylindrical structure, preferably made of stainless steel or copper. Made, set on the inner side of the combustion level 12 and the combustion level 12 in a gap se...

Embodiment 2

[0042] A kind of burner with cooling device 2 of the present invention is as image 3 , Figure 4As shown, the cross-section of the burner body 1 is rectangular, and the burner body 1 includes a combustion surface 12, which is a metal plate with combustion holes 121, preferably made of stainless steel or copper. The combustion layer 12 is sealed at one end of the gas supply chamber 11, preferably with an arc surface structure, and the combustion holes 121 are distributed on the combustion layer 12, with a total porosity of 14% to 70%; the air flow distributor 14 is arranged on In the gas supply chamber 11 and below the metal plate with the combustion holes 121, the airflow distributor 14 is a second arc panel structure that is compatible with the metal plate structure with the combustion holes 121, and the plate body of the airflow distributor 14 An air outlet 141 is arranged on it.

[0043] The heat dissipation device 2 has a fluid passage 21, the heat dissipation device 2 ...

Embodiment 3

[0046] The burner body 1 has a spherical structure, and the metal plate with the combustion hole 121 is a first spherical thin shell structure with an opening at one end, which constitutes the combustion surface 12 of the burner body 1, and the combustion on the combustion surface 12 The total porosity of the holes 121 is 14%~70%; the airflow distributor 14 is a metal plate with air holes 141, and the airflow distributor 14 is a second spherical thin shell structure compatible with the first spherical thin shell structure. The shell structure is disposed in the first spherical thin shell as a gap, and the heat sink 2 is connected with the opening end of the first spherical thin shell.

[0047] The combustion holes 121 on the combustion layer 12 in Embodiment 1, Implementation 2 and Implementation 3 are arranged in groups, and the combustion holes 121 are densely distributed in an area to form a collection and distribution unit. The collection and distribution units are arranged...

Abstract

A burner having a heat sink, comprising: a burner body (1) and a heat sink (2), the burner body (1) being connected with the heat sink (2). The burner body (1) has a gas supply chamber, or cooperates with the heat sink (2) to form the gas supply chamber (11); the burner body (1) comprises a combustion layer surface (12), and the combustion layer surface (12) is a metal plate provided with combustion holes (121) on a surface thereof, wherein the total porosity rate of the metal plate provided with the combustion holes (121) is 14%-70%. The burner has a simple structure, a small volume, a high porosity rate on the combustion layer surface (12), and high combustion efficiency; at the same time, the temperature of the burner body (1) may be effectively reduced by means of the heat sink (2), such that the burner will not be overheated and damaged while at the same time ensuring high combustion intensity.
