Description

Technical Field

[0001] The invention relates to a coiled liquid resistor device, a radiator and a chassis comprising the resistor device, and belongs to the technical field of liquid resistor devices. Background Art

[0002] Common liquid resistance devices are mostly used in large-capacity motor equipment. In some special high-voltage pulse power supplies, a water-cooled heat dissipation module is installed to achieve a heat dissipation effect that air cooling cannot achieve.

[0003] At present, high electrical heat consumption components such as inductors and transformers are in direct contact with metal water-cooled radiators to reduce thermal resistance. At the same time, some special components cannot be directly attached to the radiator. For example, barrel-shaped electrical parts need to dissipate heat on the cylindrical surface, so this kind of special-shaped electrical parts often have their own radiator structure designed. When working, the radiator is charged. Even if the water pipe is made of non-metallic material, it will not directly connect the charged radiator and the end water pipe joint. However, the cooling water flowing through the inside is already charged. After the cooling water is charged, it will generate leakage current to the grounded metal joint, affecting the performance of the electrical appliance. At the same time, the charged ions in the water will accelerate the electrochemical corrosion of the metal joint.

[0004] In addition, the internal space of a general power supply chassis is limited. Under the influence of the development trend of miniaturization and lightweight, it is difficult to place a safe and reliable but large liquid resistor device inside a power supply chassis filled with electrical components.

[0043] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Embodiment 1:

[0045] Please refer to Figure 1As shown, a coiled liquid resistor device provided by an embodiment of the present invention comprises: a pipeline guide housing 1 and a liquid resistor pipeline 2. The pipeline guide housing 1 is used to provide an installation base for the liquid resistor pipeline 2, and the liquid resistor pipeline 2 is used for circulating a coolant (preferably cold water) to dissipate heat from a heat consumption element.

[0046] Reference Figure 2 and Figure 3 As shown, the pipe guide housing 1 is flat, and has a winding track 101 of a set shape inside the pipe guide housing 1, and a track inlet 102, a first track outlet 103, and a second track outlet 104 connected to the winding track 101 are provided on the outer wall of the pipe guide housing 1; the liquid resistor pipe 2 includes a liquid inlet pipe 21 and a liquid return pipe 22, and the liquid inlet pipe 21 and the liquid return pipe 22 are wound in parallel in the winding track 101, and the first ends of the liquid inlet pipe 21 and the liquid return pipe 22 both protrude out of the track inlet 102, the second end of the liquid inlet pipe 21 protrudes out of the first track outlet 103, and the second end of the liquid return pipe 22 protrudes out of the second track outlet 104. It can be understood that as an alternative, the first track outlet and the second track outlet can also be combined into one outlet. Here, just for the convenience of understanding, the first track outlet and the second track outlet that are independent of each other are used as an example for explanation.

[0047] Reference Figure 4 As shown, this is a usage scenario diagram of the coiled liquid resistor device. Figure 4 It can be seen that by placing the flat pipe guide shell 1 on the power supply chassis 10, it will not occupy too much space of the power supply chassis 10, and the overall size of the power supply chassis 10 can be reduced to meet the requirements of miniaturization and lightweight use.

[0048] Reference Figure 5 As shown, when the internal heat dissipation element 20 of the power supply chassis 10 needs to be cooled, the first ends of the liquid inlet pipe 21 and the liquid return pipe 22 can be connected to an external water supply device (not shown in the figure); then, the second end of the liquid inlet pipe 21 is connected to the radiator liquid inlet 201 corresponding to the heat dissipation element 20, and the second end of the liquid return pipe 22 is connected to the radiator liquid return port 202 corresponding to the heat dissipation element 20; finally, the heat dissipation element 20 is cooled by circulating the cooling liquid through cold water provided by the outside. Therefore, the use of the coiled liquid resistor device can adapt to the development trend of miniaturization and light weight of the power supply chassis, thereby improving the safety and reliability of the use of the heat dissipation element in the power supply chassis.

[0049] like Figure 6As shown, the liquid resistor R4 is applied to a transformer radiator. The transformer radiator is charged. The resistance of the liquid resistor R4 should be much larger than the load R3. Assuming that the resistance of R3 is 10Ω, the resistance of the liquid resistor R4 is 100*R3, so that the power supply output error is low.

[0050] In another embodiment, referring to Figure 4 As shown, when there are two radiators (not shown), the structure of the liquid resistor is two layers. At this time, two pipe guide housings 1 are stacked and arranged, and each layer is used corresponding to one radiator, that is, the liquid inlet pipe and the liquid return pipe of each layer are respectively connected to the liquid inlet and liquid return of the corresponding radiator coolant. The two pipe guide housings 1 overlap each other, so that the planes where the center lines of the entire winding track 101 in each pipe guide housing 1 are located are roughly parallel to each other, so as to reduce the space occupied by the pipe guide housing 1, which is conducive to miniaturization and lightweight structural design.

[0051] Figure 7 It is a circuit diagram when there are two radiators 30 and the structure of the liquid resistor is two layers. At this time, the coiled liquid resistor device is connected to the heating device 40 through the radiator 30. In this embodiment, the heating device 40 is an inductor element L1, and the inductor element L1 is connected to the radiator 30 and the capacitor C1 and the 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 is equivalent to the resistor R2. Of course, the two can also be interchangeable. In one embodiment, the circuit is applied to a high-frequency pulse power supply, and the resistance values ​​of the liquid resistors R1 and R2 are required to be similar, much larger than the inductive reactance of the inductor L1, and close to the capacitive reactance of the capacitor elements C1 and C2. Assuming that the application scenario requires the inductive reactance of the inductor element L1 to be 10Ω, and the two capacitors C1 and C2 are both 5000Ω, then the resistance values ​​of the liquid resistors R1 and R2 should be approximately equal to 5500Ω.

[0052] Figure 6 and Figure 7 In both circuits shown, the risk of people accidentally touching the housing should be considered. The average resistance of the human body is about 2000Ω. In this case, the liquid resistance value should be calculated according to the specific structure of the circuit. Assuming that the liquid resistance value is R after calculation, the resistivity of the coolant varies from 2000Ω·cm (tap water) to 16MΩ·cm (pure water) due to different water quality. Therefore, it is best to calculate based on a lower resistivity to ensure safety. Assuming that Figure 6 In the application circuit, the liquid of the coiled liquid resistor device is tap water, and the resistance of the liquid inlet pipe or liquid return pipe of the liquid resistor is set to R, then the resistance 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. From the above formula, it can be seen that the resistance value R is proportional to the length of the liquid inlet pipe 21 or the liquid return pipe 22, and inversely proportional to the inner cross-sectional area of ​​the liquid inlet pipe 21 or the liquid return pipe 22, that is, the square of the inner diameter.

[0053] Therefore, when the length L of the liquid inlet pipe 21 and the liquid return pipe 22 is determined, the inner diameter D of the liquid inlet pipe 21 and the liquid return pipe 22 can be calculated; when the inner diameter D of the liquid inlet pipe 21 and the liquid return pipe 22 is determined, the length L of the liquid inlet pipe 21 and the liquid return pipe 22 can be calculated. This embodiment requires the R1 and R2 resistance values ​​of the liquid resistor to be similar, so the length and inner diameter of the liquid inlet pipe and the liquid return pipe are the same for explanation. Of course, if the resistance values ​​of the liquid inlet pipe and the liquid return pipe are different according to different application scenarios, the length and inner diameter of the liquid inlet pipe and the liquid return pipe can be calculated respectively according to the required resistance value, so that the liquid inlet pipe 21 and the liquid return pipe 22 of suitable length and specification can be selected according to different use conditions to ensure the safety and reliability of the use of the coiled liquid resistor device.

[0054] Reference Figure 2 and Figure 3 As shown, in the above embodiment, preferably, the duct guide housing 1 includes a main body 11 and a cover plate 12; wherein the main body 11 is generally a flat elliptical structure, and the top of the main body 11 is recessed inward to form a receiving cavity, and the receiving cavity has a winding track 101 of a set shape, and the track entrance 102, the first track exit 103 and the second track exit 104 are all provided on the main body 11. The center line of the entire winding track 101 in the duct guide housing 1 is located in the same plane. When multiple duct guide housings 1 are needed, all duct guide housings 1 are overlapped together so that the planes where the center lines of the entire winding track 101 in each duct guide housing 1 are located are parallel to each other.

[0055] The cover plate 12 is detachably covered on the top of the main body 11 to limit the relative position of the liquid resistance pipe 2 and the pipe guide housing 1. Specifically, in this embodiment, the pipe guide housing 1 is composed of the main body 11 and the cover plate 12, wherein the inner bottom surface of the main body 11 is a winding plane for winding the liquid resistance pipe 2. When the liquid resistance pipe 2 is wound, the cover plate 12 is used to restrict the liquid resistance pipe 2 inside the main body 11 to prevent the liquid resistance pipe 2 from being separated from the main body 11. At the same time, the detachable connection between the main body 11 and the cover plate 12 can facilitate the assembly and disassembly of the liquid resistance pipe 2.

[0056] Continue to refer to Figure 3As shown, in the above embodiment, preferably, the pipeline guide housing 1 also includes a plurality of pressure strips 13, and the pressure strips 13 are long strip structures. Preferably, the pressure strips 13 are in the shape of a rectangular parallelepiped, and the plurality of pressure strips 13 are evenly pressed above the winding track 101 to prevent the liquid resistance pipeline 2 from tilting. Specifically, in this embodiment, the depth of the winding track 101 is generally slightly larger than the diameter of the liquid inlet pipeline 21 and the liquid return pipeline 22. When the liquid inlet pipeline 21 and the liquid return pipeline 22 are coiled in parallel in the winding track 101, the pressure strips 13 are arranged at the positions on the winding track 101 where the liquid inlet pipeline 21 and the liquid return pipeline 22 are easy to tilt, thereby stably restricting the liquid resistance pipeline 2 in the main body 11. Therefore, the use of the pressure strips 13 in conjunction with the cover plate 12 can prevent the liquid resistance pipeline 2 from tilting or moving relative to the pipeline guide housing 1, thereby further improving the stability of the liquid resistance pipeline 2.

[0057] In the above embodiment, preferably, the liquid resistor pipe 2 is made of a high-performance and high-toughness insulating material, such as: PFA (Perfluoroalkoxy, fusible polytetrafluoroethylene), PTFE (Polytetrafluoroethylene, polytetrafluoroethylene), etc., which will produce a very small pipe bending radius and facilitate assembly. At the same time, the pipe guide shell 1 needs to have a certain mechanical strength and processability to meet its geometric shape processing and molding, and is not easy to deform, such as: nylon 6 with 30% glass fiber added, PEEK (polyetheretherketone), etc. In addition, the pressure strip 13 fixes the liquid resistor pipe 2 that is easy to warp, and also requires a high mechanical strength insulating material, such as: nylon 6 with 30% glass fiber.

[0058] Continue to refer to Figure 2 As shown, in the above embodiment, preferably, the cover plate 12 includes a first insulating plate 121 and a second insulating plate 122, the first insulating plate 121 is covered on the top of the main body 11, and the second insulating plate 122 is covered on the top of the first insulating plate 121, and the thickness of the first insulating plate 121 is less than the thickness of the second insulating plate 122. Specifically, in this embodiment, the first insulating plate 121 and the second insulating plate 122 are both made of insulating materials to achieve a multi-layer insulation effect by double-layer stacking. At the same time, since the first insulating plate 121 only plays an insulating role, in order to reduce space occupation, a 0.5mm polyimide film can be used, and the dielectric strength of the material is 100-300kv / mm; and the second insulating plate 122 not only plays an insulating role but also plays a capping role, so a thicker insulating material can be used, such as: PTFE (Polytetrafluoroethylene, polytetrafluoroethylene), PPS (Polyphenylenesulphide, polyphenylene sulfide), etc.

[0059] Reference Figure 2 and Figure 3 As shown, in the above embodiment, preferably, a positioning pin 111 is provided on the top end surface of the main body 11, and a positioning pin hole 123 is provided at a position corresponding to the pin 111 on the cover plate 12, and the positioning pin 111 is inserted into the positioning pin hole 123 to relatively position the main body 11 and the cover plate 12. Specifically, when it is necessary to buckle the cover plate 12 on the main body 11, the positioning pin 111 is first aligned with the positioning pin hole 123, and when the positioning pin 111 passes through the positioning pin hole 123, the cover plate 12 and the main body 11 are aligned with each other, and then the cover plate 12 and the main body 11 can be detachably connected by bolts or snaps. Therefore, the mutual cooperation of the positioning pin 111 and the positioning pin hole 123 can improve the convenience of assembling the main body 11 and the cover plate 12.

[0060] In the above embodiment, preferably, the winding track 101 includes a plurality of circular tracks that are successively wrapped in a circle, and each circular track is provided with a notch portion 105 so that any two adjacent circular tracks are interconnected. Specifically, in this embodiment, a plurality of circular tracks that are successively wrapped in a circle refer to a plurality of circular tracks of different sizes, with the smallest circular track being on the innermost side, a slightly larger circular track being wrapped in a circle on the outer side of the smallest circular track, a larger circular track being wrapped in a circle on the outer side of a slightly larger circular track, and so on. When it is necessary to coil the liquid resistor pipeline 2, start coiling from the outermost circular track, and after coiling to the notch portion 105, enter the next circular track until it is coiled to the smallest circular track. It can be understood that the winding track 101 is not limited to this structural form.

[0061] In another embodiment, the winding track 101 can be directly wound in a spiral shape to form a "mosquito-repellent-coil-type" winding structure, which is relatively simple and also convenient for winding the liquid resistance pipe 2. In addition, it should be understood that the specific shape of the winding track 101 can be designed according to needs, such as: circular, elliptical, square, etc., which is not specifically limited here. At the same time, in this embodiment, the liquid resistance pipe 2 is only wound in the bottom plane of the winding track 101, thereby forming a single-layer winding structure.

[0062] In another embodiment, the liquid resistance pipe 2 can be wound along the winding track 101 into a two-layer or three-layer winding structure, that is, the liquid resistance pipe 2 is in a spiral ascending structure in the winding track 101, but it should be noted that the overall height of the liquid resistance pipe 2 after winding cannot exceed the depth of the winding track 101. Therefore, the liquid resistance pipe 2 can be wound not only in the bottom plane of the winding track 101, but also in the plane above the bottom plane of the winding track 101 to meet different usage requirements.

[0063] In addition, it should be understood that in the present embodiment, no matter whether the liquid resistor pipe 2 is wound in a single layer or multiple layers, there is only one passage, that is, the liquid inlet pipe 21 and the liquid return pipe 22 are both a pipe that passes through the pipe guide shell 1, thereby improving the convenience of assembly and reducing the pipe interfaces to ensure sealing.

[0064] Embodiment 2:

[0065] Reference Figure 8 As shown, on the basis of the first embodiment, preferably, the coiled liquid resistor device further includes a plurality of connectors 3, there are a plurality of pipe guide shells 1, and a liquid resistor pipe 2 is coiled in each pipe guide shell 1; the plurality of pipe guide shells 1 are stacked in a vertical direction, and a connecting hole 106 is provided on each pipe guide shell 1, and the connector 3 is disposed between two adjacent pipe guide shells 1 and is respectively connected and fixed to the connecting holes 106 of the two adjacent pipe guide shells 1 to limit the relative position of the two adjacent pipe guide shells 1.

[0066] In this embodiment, specifically, since the flat pipe guide housing 1 does not occupy too much space in the power supply chassis 10, a plurality of flat pipe guide housings 1 can be stacked on the power supply chassis 10 to dissipate heat for different heat dissipating elements 20 respectively, thereby improving the overall heat dissipation effect of the heat dissipating elements 20 in the power supply chassis 10. Figure 4 At the same time, by arranging the connector 3 between two adjacent pipeline guide housings 1, the pipeline guide housings 1 of each layer can be relatively fixed, thereby ensuring the stability and reliability of the use of the coiled liquid resistor device.

[0067] Reference Fig. 9 and Fig.10As shown, in the above embodiment, preferably, the connecting member 3 includes a connecting bolt 31 and a locking nut 32, the connecting bolt 31 has a top thread 311, a middle thread 312 and a bottom thread 313, and the connecting hole 106 is a threaded hole; the top thread 311 and the bottom thread 313 of the connecting bolt 31 are respectively threadedly matched with the threaded holes 107 of the two adjacent pipe guide shells 1 to limit the relative position of the two adjacent pipe guide shells 1; the middle thread 312 of the connecting bolt 31 is threadedly matched with the locking nut 32 to limit the relative position of the cover plate 12 and the main body 11. Specifically, when it is necessary to connect the pipe guide housings 1, firstly, the bottom thread 313 of the connecting bolt 31 is threadedly connected with the pipe guide housing 1 located below the connecting bolt 31, and then, the locking nut 32 is rotated clockwise until the locking nut 32 is pressed on the top of the cover plate 12, thereby pressing the cover plate 12 on the main body 11, further improving the overall stability of the pipe guide housing 1; finally, the pipe guide housing 1 located above the connecting bolt 31 is stacked on the connecting bolt 31 through the top thread 311, forming a multi-layer pipe guide housing 1 parallel structure to provide heat dissipation for multiple heat consumption components. Therefore, the threaded connection can improve the stability of the connection of the pipe guide housing 1 on the one hand, and improve the convenience of the connection of the pipe guide housing 1 on the other hand.

[0068] Reference Fig.11 As shown, in the above embodiment, preferably, the coiled liquid resistor device further includes a support portion 4, the support portion 4 includes at least one bracket 41 and at least one reinforcement strip 42, the bracket 41 is arranged at the bottom of the pipe guide housing 1 to support the pipe guide housing 1, and the reinforcement strip 42 is installed on the bracket 41 to enhance the structural strength of the bracket 41. Specifically, in this embodiment, the bracket 41 can be installed on the power supply chassis 10, and then the bracket 41 is used to provide a stable support for the pipe guide housing 1, and at the same time, the reinforcement strip 42 can improve the structural strength of the bracket 41 to ensure the stability and reliability of the support.

[0069] In the above embodiment, preferably, the bracket 41 includes a first support rod 411 and a second support rod 412, the reinforcement strip 42 includes a first reinforcement strip 421 and a second reinforcement strip 422, and at least two support rod mounting holes 107 are provided on the pipeline guide housing 1; the first support rod 411 and the second support rod 412 are respectively inserted into the two support rod mounting holes 107, the first end of the first reinforcement strip 421 is sleeved on the first support rod 411, the first end of the second reinforcement strip 422 is sleeved on the second support rod 412, and the second end of the first reinforcement strip 421 is detachably connected to the second end of the second reinforcement strip 422. Therefore, since the reinforcement strip 42 is detachable, the position of the pipeline guide housing 1 can be changed as needed to avoid affecting the installation of other components in the chassis.

[0070] The present invention is described in detail above. For those skilled in the art, any obvious changes made to the present invention without departing from the essence of the present invention will constitute an infringement of the patent right of the present invention and the corresponding legal liability will be borne.
