[0021] The utility model is now further described with reference to the accompanying drawings.

[0022] like Figures 1 to 7 As shown, a flow channel structure for double-sided heating includes a water inlet 11, a water outlet 12, a heating chamber 10 and a plurality of partitions 13 arranged on a heating seat 1, the heating chamber 10 is communicated with the water inlet 11 and the water outlet 12, and passes through the top surface and the bottom surface of the heating seat 1, and the heating chamber 10 is a through groove; the partitions 13 are alternately arranged at the two ends of the heating chamber 10 in sequence, so that the heating chamber 10 forms a circuitous flow channel 14 whose two ends are respectively communicated with the water inlet 11 and the water outlet 12; the heating substrate 2 is installed on the top surface and the bottom surface of the heating seat 1, and is located on both sides of the heating chamber 10, and is used to heat the liquid from both sides of the circuitous flow channel 14.

[0023] One end of the partition 13 is connected to one side of the heating chamber 10, and a gap is left between the other end and the other side of the heating chamber 10, and the gap is used to connect adjacent flow channels. The partitions 13 are staggered at the two ends of the heating chamber 10 in sequence, which means that when one end of one of the partitions 13 is set on one side of the heating chamber 10, one end of another adjacent partition 13 is set on the other side of the heating chamber 10, forming a staggered structure, thereby forming a flow channel that goes back and forth from one end of the heating seat 1 to the other end. The connection between the partition 13 and the heating chamber 10 is an arc shape, which can effectively avoid the formation of a dead water area, prevent the heating substrate 2 from dry burning, and improve the service life of the heating substrate 2 and the reliability of the heater.

[0024] The circuitous flow channel 14 is arranged from one end to the other end of the heating seat 1 and extends along the width direction of the heating seat 1, so that the liquid flows back and forth between the two ends of the heating seat 1, extending the flow time of the liquid, that is, extending the contact time with the heating substrate 2, thereby improving the heating efficiency.

[0025] The heating substrate 2 is heated from both sides of the circuitous flow channel 14, which increases the contact area with the liquid, improves the efficiency of heat exchange, and can reduce the area of ​​the heating substrate 2 and the area of ​​the heater.

[0026] The water inlet 11 and the water outlet 12 are located at the same end of the heating seat 1 and are respectively located on both sides of the end, so as to facilitate the connection of pipelines.

[0027] The plurality of partitions 13 are arranged parallel to each other and at equal intervals, so that the width of the circuitous flow channel 14 is consistent, so that the liquid flows stably, which is beneficial to increase the flow rate and realize rapid heat exchange.

[0028] In order to prevent the partition 13 from deforming, three connecting columns 15 are further arranged in the heating chamber 10, the two ends of the connecting column 15 are respectively fixed on the two sides of the heating chamber 10, the connecting column 15 is also connected to the partition 13, and the connecting column 15 is respectively located at the two ends and the middle position of the partition 13, which effectively ensures that the partition 13 does not deform under high-speed water flow, thereby improving the stability and reliability of operation. Among them, the connecting column 15 can be a circular column, which has little effect on the water flow and is not easy to form a dead water area.

[0029] In order to prevent the formation of dead water areas at the water inlet 11 and the water outlet 12, a flushing bay 16 is provided between the water inlet 11 and the water outlet 12 and the circuitous flow channel 14. The flushing bay 16 is located on one side of the water inlet 11 and the water outlet 12, and can form turbulence without generating dead water areas, thereby avoiding dry burning of the heating substrate 2, thereby improving the reliability and service life of the heating plate.

[0030] The heating seat 1 is an integral structure, formed by aluminum die-casting, and has low cost and convenient processing.

[0031] like Figure 6 and Figure 7 As shown, the liquid enters from the water inlet 11, and then flows out from the water outlet 12 through the circuitous flow channel 14. The liquid is heated by the heating substrates 2 on both sides in the circuitous flow channel 14, which can achieve rapid heating with high heating efficiency. At the same time, it can achieve higher power per unit volume and power per unit mass, achieve higher heating power in a limited structural area, reduce the heating power density of the heating substrate 2, and thus improve the reliability and life of the heater.

[0032] The flow velocity of the circuitous flow channel 14 is uniform and there is no dead water area, so that the heat on the heating substrate 2 in the local area cannot be taken away by the liquid, thereby preventing dry burning.

[0033] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
