Problems solved by technology

[0002] Heat exchangers are widely used in various fields of the national economy and are closely related to human life. The key equipment for energy saving and consumption reduction. The performance, quality and cost of the heat exchangers currently in use have various problems, such as microchannels. The inlet and outlet settings of the plate heat exchanger have poor reliability and are in cross-flow heat exchange, so that the overall heat load is unbalanced and the cost is high. The finned plate (tube) heat exchanger is suitable for heat exchange between gas and liquid, but the consumables and cost are high. The side flow resistance makes the energy consumption high and it is not easy to form the variable cross-section flow channel of the evaporator and condenser and the waste heat recovery. It is especially not suitable for high temperature conditions. The exhaust gas purification device of the internal combustion engine cannot adjust the temperature, so that it does not work during cold start and regeneration. High-temperature melting and thermal stress crack damage, low-temperature catalytic reduction effect is not good, civil air-conditioning is only the temperature regulation of heat transfer indoors and outdoors without using heat and no fresh air conditioning, especially in places with many people in winter with direct exhaust fans Air exchange without heat recovery, and waste heat refrigeration also have heat pumps that are not practical and meaningful, such as large devices, or low cooling performance and cost performance. To solve these problems, to improve energy utilization and achieve the goal of carbon peaking as soon as possible requires a more advanced New heat transfer structure technology with excellent heat transfer performance and high cost performance

Embodiment 1

[0028] What embodiment one provides is the accordion open heat exchanger, is the accordion open heat exchanger of the various import and export forms mainly composed of accordion I 1, such as Figure 1~3 As shown, the accordion open heat exchanger is composed of an accordion I 1, a seal 5, a sealing plate II 1, a first inlet collection box 6 with a total inlet, and a first outlet collection box 7 with a total outlet.

[0029] A: Accordion I 1 is a heat exchange structure. On a thin metal plate 1, several heat exchange surface units 2 with the same area and equal intervals are arranged according to the same length, and various shapes are stamped on them, and then folded repeatedly. Ensure that the folded heat exchange surface units 2 are connected and stacked together to form the first flow channel 3 and the thin plate 1 on one side separated by the thin plate 1 and conducting heat from the heat exchange surface unit 2 and composed of one wall surface of the thin plate 1 The se...

Embodiment 2

[0044] Embodiment 2: what embodiment 2 provides is an accordion heat exchanger, which is an accordion heat exchanger with closed flow passages on both sides formed by accordion I 1, such as Figure 4 As shown, on the basis of Embodiment 1, the other side flow channel and the corresponding end of the accordion I1 are blocked with the sealing plate II 2 and the sealing strip 5 respectively to form the inlet and outlet of the side flow channel and further The second inlet converging box 8 with the total inlet and the second outlet converging box 9 with the total outlet are arranged, thus forming the second inlet converging box 8 with the total inlet and the second flow channel 4 of the accordion I1 in sequence , The second path of the accordion I1 of the second outlet converging box 9 with the total outlet, and an accordion heat exchanger for heat exchange on the first path.

[0045] The flow openings on both sides of the partition wall accordion heat exchanger should not be set ...

Embodiment 3

[0048] What embodiment three provides is an open double accordion heat exchanger, such as Figure 5 As shown, on the basis of Embodiment 1, further, the ends of the first flow passage 3 and the second flow passage 4 of the accordion I 2 are blocked symmetrically with the sealing plate II 1 and the sealing strip 5, so that the first flow passage of the accordion I 2 The inlet and outlet of the channel 3 and the inlet and outlet of the second flow channel 4 of the accordion I1 are respectively merged into an inlet pooling box 10 with a total inlet and an outlet pooling box 11 with a total outlet at both ends, thus forming a total import pool in turn The second flow channel 4 of the box 10, the accordion I 1 is connected in parallel with the first flow channel 3 of the accordion I 2, and the heat exchange path of the total outlet collection box 11 is connected with the open first flow channel 3 of the accordion I 1 and the accordion I 2 respectively The heat exchanging passage of...

Abstract

The invention relates to an accordion type heat exchanger, thin plates are punched, repeatedly folded and stacked together to form a plurality of long and narrow first flow channels and second flow channels of the accordion, then sealing plates and sealing strips are used for blocking the flow channels and the corresponding ends of the accordion to form flow channel inlets and outlets, and inlet and outlet collecting boxes are arranged on the flow channel inlets and outlets. Therefore, the accordion type heat exchanger for exchanging heat between a first heat exchange passage and a second heat exchange passage is formed, and various structures and various functional devices can be formed.
