Problems solved by technology

[0004] In view of the above defects or improvement needs of the prior art, the object of the present invention is to provide a multi-channel burner, wherein the structure of the key combustion channels and its arrangement, the equivalent of the combustible gas-oxidant mixture in each channel Compared with the prior art, it can effectively solve the problem that the micro burner dissipates heat quickly and the temperature cannot be further increased, and the outer surface of the burner used to radiate photons to the photovoltaic power generation device has good temperature uniformity, and the radiated photon energy It is more concentrated (photon energy also increases with the increase of burner temperature), and the proportion of radiated photons used by photovoltaic power generation devices to generate photovoltaic power generation effects is also greatly improved, making the photovoltaic power generation devices used in conjunction with this burner have good performance. Thermal photovoltaic power generation effect improves the comprehensive conversion efficiency of energy

Embodiment 1

[0032] Such as figure 1 As shown, the miniature multi-channel burner in this embodiment consists of microchannel I1, microchannel II2, microchannel III3, microchannel IV4, microchannel V5 and housing 6 (that is, for the outer surface of photon radiation to the photovoltaic power generation device) The overall structure is in the shape of a cuboid.

[0033] Microchannel I1, microchannel II2, microchannel III3, microchannel IV4, and microchannel V5 have the same size parameters, and their central axes are parallel and at the same distance.

[0034] The micro-multi-channel burner is composed of five micro-cylindrical structural channels arranged in parallel, juxtaposed and equidistant; The channel is long and straight, the center line of the channel is parallel to the length direction of the channel, and the upstream of each micro channel is provided with sudden expansion steps. The realization method of the sudden expansion step is: the diameter of the entrance of the first se...

Abstract

The invention discloses a multi-channel combustor. The multi-channel combustor comprises a plurality of parallel combustion channels, wherein central lines of the plurality of combustion channels are parallel to each other and are positioned on the same plane; each combustion channel comprises a first channel section and a second channel section; the sectional area of a channel part, in the direction vertical to the central line of each combustion channel, of each first channel section, is less than the sectional area of the channel part, in the direction vertical to the central line of each combustion channel, of the corresponding second channel section; combustible gas can combust through the combustion channels; the central lines of every two of the plurality of combustion channels have the same spacing. According to the multi-channel combustor, the surface temperature is high, and the temperature uniformity is high; photons can be radiated to a photovoltaic generating device to enable thermophotovoltaic generating effect, thus improving the comprehensive energy conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of micro-scale combustion, and more specifically relates to a multi-channel burner, which is a micro-burner suitable for micro-power / power generation systems, and can be applied to micro-thermal photovoltaic power generation systems and the like. Background technique [0002] With the progress of human society, people's demand for various civil and military miniature portable devices is increasing. The rapid development of micro-processing technology has made it possible to manufacture these micro-electro-mechanical systems and devices, and portable electronic devices such as micro-satellites, micro-robots, and mobile phones have appeared one after another. At present, most of these devices are driven by traditional chemical batteries. However, batteries have disadvantages such as low energy density, large volume and weight, and long charging time. The energy density of hydrocarbon fuels is 50-100 times high...
