Problems solved by technology

[0003] However, when the traditional radiant air conditioning system or energy harvester system is used in engineering applications, the fluid flows in the small holes of the capillary tubes, and the heat transfer surface is the capillary tubes themselves. The heat transfer area is relatively small, and there is no formation between the capillary tubes. The same heat exchange surface as a whole, in order to maximize the heat exchange efficiency; at the same time, as the end of the radiant air conditioner, in practical applications, it is necessary to form a heat exchange surface with a flat metal or fill other materials (such as cement slurry, gypsum mortar, etc.) ) to form a heat exchange radiation surface, which increases the complexity of the specific construction and installation, and the cost is relatively high; and if it is used as an energy harvester, the heat exchange area is also small

Embodiment 1

[0028] Embodiment 1: refer to image 3 As shown, the heat exchange surface 3 of the heat exchange orifice plate 2 is a flat structure, and a plurality of microholes or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the microhole or small hole flow channels 4 is circular Structure; the heat exchange surface 3 itself is the maintenance structure of the micropore or small hole flow channel 4.

Embodiment 2

[0029] Embodiment 2, with reference to Figure 4 As shown, the heat exchange surface 3 of the heat exchange orifice plate 2 is a flat structure, and a plurality of micropores or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the micropore or small hole flow channels 4 is oval Structure; the heat exchange surface 3 itself is the maintenance structure of the micropore or small hole flow channel 4.

Embodiment 3

[0030] Embodiment 3, with reference to Figure 5 As shown, a plurality of micropores or small hole flow channels 4 are arranged side by side in the heat exchange orifice plate 2, and the cross section of the micropore or small hole flow channels 4 is an elliptical structure. The shape of the hole or small hole flow channel 4 is wavy; the heat exchange surface 3 itself is the maintenance structure of the micro hole or small hole flow channel 4 .

[0031] The working principle of the present invention is as follows:

[0032] 1. Heat absorption process from high temperature environment: the low temperature fluid in the collecting and distributing pipe 1 is distributed to the micropore or small hole flow channel 4 of the heat exchange orifice plate 2, and the heat exchange orifice plate through which the thinned low temperature liquid passes The overall heat exchange surface 3 of 2 forms a low-temperature heat exchange surface, which absorbs ambient heat from the high temperature...

Abstract

The invention relates to a heat transfer surface and microporous flow passages or small-hole flow passages integrated planar perforated-plate heat exchanger which comprises a flow distribution pipe, a flow collection pipe and a heat exchange perforated plate. The heat exchange perforated plate is connected between the flow distribution pipe and the flow collection pipe, the heat exchange perforated plate is internally and parallelly provided with a plurality of microporous flow passages or small-hole flow passages, and two ends of the microporous flow passages or the small-hole flow passages are communicated with the flow distribution pipe and the flow collection pipe respectively. Sections of the flow distribution pipe and the flow collection pipe are C shaped, and two ends of the heat exchange perforated plate are welded C-shaped openings of the flow distribution pipe and the flow collection pipe respectively to form an integral flow passage communicated structure. Compared with a traditional capillary network heat exchanger, the planar perforated-plate heat exchanger structurally has the advantages of avoidance of secondary construction for forming of the heat exchange surface, high heat exchange efficiency, low cost, convenience in mounting and the like.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a novel orifice planar heat exchanger suitable for radiation air conditioning systems or energy harvesters. Background technique [0002] At present, in the radiant air conditioning system, the end of the air conditioner is a capillary heat exchanger, which generally achieves the purpose of cooling or heating through the cold and hot water circulating in the grid in the capillary; when used as an energy harvester, it is the same as air, water, Soil etc. exchange heat. [0003] However, when the traditional radiant air-conditioning system or energy harvester system is applied in engineering, the fluid flows in the small holes of the capillary tubes, and the heat transfer surface is the capillary tube itself, the heat transfer area is relatively small, and there is no formation between the capillary tubes. The same heat exchange surface as a whole, in order to maximize the heat ...
