Referring to fig. 2 and 3, the pipeline guide housing 1 is flat, a coiled track 101 with a set shape is arranged in the pipeline guide housing 1, and a track inlet 102, a first track outlet 103 and a second track outlet 104 which are communicated with the coiled track 101 are arranged on the outer wall of the pipeline guide housing 1; the liquid resistance pipeline 2 comprises a liquid inlet pipeline 21 and a liquid return pipeline 22, the liquid inlet pipeline 21 and the liquid return pipeline 22 are coiled in the coiling track 101 in parallel, the first ends of the liquid inlet pipeline 21 and the liquid return pipeline 22 protrude out of a track inlet 102, the second end of the liquid inlet pipeline 21 protrudes out of a first track outlet 103, and the second end of the liquid return pipeline 22 protrudes out of a second track outlet 104. It will be appreciated that the first track outlet and the second track outlet may alternatively be combined into one outlet. Here, the first track outlet and the second track outlet which are independent of each other are described as an example, only for convenience of understanding.
Referring to fig. 4, a usage scenario of the coiled liquid resistor device is shown, and it can be seen from fig. 4 that the flat pipe guide housing 1 is placed on the power supply enclosure 10, so that the power supply enclosure 10 does not occupy too much space, the overall size of the power supply enclosure 10 can be reduced, and the requirements of miniaturization and light weight can be met.
Referring to fig. 5, when the internal heat consuming elements 20 of the power supply cabinet 10 need to be cooled, first ends of the liquid inlet pipe 21 and the liquid return pipe 22 may be connected to an external water supply device (not shown); then, the second end of the liquid inlet pipe 21 is communicated with the liquid inlet 201 of the radiator corresponding to the heat consumption element 20, and the second end of the liquid return pipe 22 is communicated with the liquid return port 202 of the radiator corresponding to the heat consumption element 20; finally, the heat consuming element 20 is cooled by supplying cold water from the outside to circulate the cooling liquid. Therefore, the coiled liquid resistance device can adapt to the development trend of miniaturization and light weight of the power supply case, and further improve the safety and reliability of the use of the heat dissipation element in the power supply case.
As shown in fig. 6, the liquid resistor R4 is applied to a transformer radiator, the transformer radiator is electrified, the resistance of the liquid resistor R4 is much larger than that of the load R3, and if the resistance of the liquid resistor R3 is 10 Ω, the resistance of the liquid resistor R4 is 100 × R3, so that the power output error is low.
In another embodiment, referring to fig. 4, when there are two radiators (not shown), the liquid resistor has a two-layer structure, and then two pipe guide housings 1 are stacked, where each layer is used in correspondence with one radiator, that is, the liquid inlet pipe and the liquid return pipe of each layer are respectively communicated with the liquid inlet and the liquid return port of the coolant of the corresponding radiator. The two pipeline guide housings 1 are overlapped together, so that planes on which the center lines of the whole coiling tracks 101 in each pipeline guide housing 1 are located are approximately parallel to each other, the occupied space of the pipeline guide housings 1 is reduced, and the miniaturization and light-weight structural design is facilitated.
Fig. 7 is a schematic circuit diagram of two radiators 30 and a liquid resistor having a two-layer structure, in this case, the coiled liquid resistor device is connected to the heat generating device 40 through the radiator 30, in this embodiment, the heat generating device 40 is an inductance element L1, the inductance element L1 is connected to the radiator 30, and a capacitor C1 and a capacitor C2, the radiator 30 transmits the cooling liquid through the liquid inlet pipe 21 and the liquid return pipe 22 of the liquid resistor, and the first layer of the liquid resistor is equivalent to the resistor R1, and the second layer of the liquid resistor is equivalent to the resistor R2, which may be interchanged. In one embodiment, the circuit is applied to a high-frequency pulse power supply, the resistance values of the R1 and the R2 of the liquid resistor are required to be approximate and far larger than the inductive reactance of the inductor L1, and simultaneously are close to the capacitive reactance of the capacitor elements C1 and C2, and if the application scene requires that the inductive reactance of the inductor element L1 is 10 Ω, and the two capacitors C1 and C2 are both 5000 Ω, the resistance values of the R1 and the R2 of the liquid resistor are required to be approximately equal to 5500 Ω.
In both circuits shown in fig. 6 and 7, the risk of a person touching the housing by mistake is considered, and the average resistance of the human body is about 2000 Ω, in which case the liquid resistance value is calculated according to the specific structure of the circuit. Assuming that the calculated liquid resistance is R, the resistivity of the coolant varies from 2000. Omega. Cm (tap water) to 16M. Omega. Cm (pure water) depending on the water quality. It is preferable to make the calculation based on the lower resistivity to ensure safe use. Assuming that, in the application circuit of fig. 6, the liquid of the coiled liquid resistor device is tap water, and the resistance value of the liquid inlet pipe or the liquid return pipe of the liquid resistor is set to R, the resistance value R satisfies the formula:
wherein, L is the length of the liquid inlet pipe 21 or the liquid return pipe 22, and D is the inner diameter of the liquid inlet pipe 21 or the liquid return pipe 22. As can be seen from the above formula, the resistance value R is proportional to the length of the liquid inlet pipe 21 or the liquid return pipe 22; inversely proportional to the square of the internal cross-sectional area, i.e. the internal diameter, of the inlet conduit 21 or the return conduit 22.
Therefore, after the lengths L of the liquid inlet pipeline 21 and the liquid return pipeline 22 are determined, the inner diameters D of the liquid inlet pipeline 21 and the liquid return pipeline 22 can be calculated; when the inner diameters D of the liquid inlet pipe 21 and the liquid return pipe 22 are determined, the lengths L of the liquid inlet pipe 21 and the liquid return pipe 22 can be calculated. The embodiment is that R1 and R2 resistance that need liquid resistance are approximate, therefore the length and the internal diameter of feed liquor pipeline and liquid return pipeline are all the same the condition explains, certainly if need feed liquor pipeline and liquid return pipeline's resistance is different according to different application scenarios, can calculate the length and the internal diameter of feed liquor pipeline and liquid return pipeline respectively according to required resistance value to can select the feed liquor pipeline 21 and the liquid return pipeline 22 of suitable length and specification according to the use operating mode of difference, with security and the reliability of guaranteeing to coil formula liquid resistance device use.

The center line of the entire coil track 101 in the pipe guide housing 1 is located on the same plane. When a plurality of the pipe guide housings 1 are required, all the pipe guide housings 1 are overlapped so that the planes in which the center lines of the entire winding tracks 101 in each pipe guide housing 1 are located are parallel to each other.
The cover plate 12 is detachably provided on the top of the main body 11 to restrict the relative position of the liquid resistance tube 2 and the tube guide housing 1. Specifically, in this embodiment, the pipe guide housing 1 is composed of a main body portion 11 and a cover plate 12, wherein the inner bottom surface of the main body portion 11 is a winding plane for winding the liquid resistance pipe 2, and after the liquid resistance pipe 2 is wound, the liquid resistance pipe 2 is limited inside the main body portion 11 by the cover plate 12 to prevent the liquid resistance pipe 2 from being separated from the main body portion 11.

In the above embodiment, it is preferable that the liquid resistance pipe 2 is made of a high-performance high-toughness insulating material such as: PFA (perfluorakoxy, meltable Polytetrafluoroethylene), PTFE (Polytetrafluoroethylene), etc., which results in a small pipe bending radius for easy assembly.
