Description

Technical Field

[0001] The utility model relates to the technical field of charging module structures, in particular to a liquid-cooled charging power supply heat dissipation device. Background Art

[0002] In the field of new energy, the charging power module is one of the indispensable and important components. The charging power module is a device that provides power to electronic devices. Because there are energy conversion circuits inside the device, and there are coils, resistors, MOS tubes and other modules, a lot of heat will be generated during the energy conversion process. Therefore, in order to ensure the normal operation of components, the heat must be dissipated.

[0003] At present, a Chinese patent discloses a liquid-cooled charging power supply heat dissipation device and a charging power supply (authorization announcement number is CN209594132U). By directly setting a liquid circulation channel on the heat dissipation plate, the complexity of the heat dissipation device processing and installation process is simplified; product costs are reduced; and production efficiency is improved.

[0004] Since the above-mentioned device circulates liquid cooling medium through an infusion pump to conduct away heat, the liquid cooling medium takes away the heat and is then transported into the heat sink. Moreover, as the use time increases, the temperature of the liquid cooling medium itself will also increase, which will gradually reduce the cooling effect of the liquid cooling medium on the heat sink during the bonding period, and the practicality is relatively low.

[0005] Therefore, a liquid-cooled charging power supply heat dissipation device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a liquid-cooled charging power supply heat dissipation device in order to solve the above-mentioned problem, which improves the problem that the existing liquid-cooled charging power supply heat dissipation device is easy to accumulate heat and the heat dissipation effect becomes worse with the use time.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme, a liquid-cooled charging power supply heat dissipation device, including: a liquid cooling plate and an infusion pump, the infusion pump is fixedly connected to the liquid outlet end of the liquid cooling plate; a heat dissipation mechanism, the heat dissipation mechanism is fixedly connected and communicated between the liquid outlet end of the infusion pump and the liquid inlet end of the liquid cooling plate.

[0008] Preferably, the heat dissipation mechanism includes a liquid guide tube fixedly connected and connected between the liquid outlet end of the infusion pump and the liquid inlet end of the liquid cooling plate, the surface of the liquid guide tube is fixedly connected and connected to a round box, the interior of the round box is rotatably connected to a transmission shaft, one end of the transmission shaft passes through the outside of the round box and is rotatably connected to the liquid cooling plate, the surface of the transmission shaft is fixedly connected to a liquid guide sheet, the surface of the transmission shaft is fixedly connected to a fan blade, the heat dissipation mechanism can guide the airflow by itself with the help of the flow force of the liquid-cooling medium to dissipate heat for the liquid-cooling medium passing through, which effectively reduces the temperature of the liquid-cooling medium to ensure that the liquid-cooling medium entering the serpentine liquid guide cavity can always absorb heat, thereby achieving the heat dissipation effect of the charging power supply, and this does not require the installation of an independent power source for the fan blades to achieve a good energy-saving effect.

[0009] Preferably, the center point of the round box coincides with the axis line of the transmission shaft, and both the center point of the round box and the axis line of the transmission shaft are arranged above the liquid guide tube, which can ensure that the liquid cooling medium always flows under the transmission shaft to ensure that the fan blades rotate continuously in one direction.

[0010] Preferably, the number of the liquid guiding plates is not less than six, and the liquid guiding plates are distributed on the surface of the transmission shaft in a ring shape around the axis of the transmission shaft, which can increase the rotation speed of the fan blades to improve the heat dissipation effect of the liquid cooling medium.

[0011] Preferably, the surface of the liquid guide tube is fixedly connected with an air guide tube which is evenly distributed and not connected to the inside of the liquid guide tube, and the axis of the air guide tube is parallel to the axis of the transmission shaft, which can increase the indirect contact area between the heat-conducting airflow and the liquid-cooling medium, and further improve the heat dissipation effect of the liquid-cooling medium.

[0012] Preferably, the top of the liquid cooling plate is fixedly connected with evenly distributed air guide vanes, and the air guide vanes are arranged between the fan blades and the air guide duct, which can guide the air guided by the fan blades to both sides, thereby increasing the heat dissipation area of ​​the liquid cooling medium and further improving the heat dissipation effect of the liquid cooling medium.

[0013] Preferably, a sealed bearing is fixedly connected to the surface of the transmission shaft, and the sealed bearing is embedded and installed inside the round box. Without affecting the normal rotation of the transmission shaft, the sealed bearing can seal the gap between the transmission shaft and the round box to prevent the liquid cooling medium from leaking outward.

[0014] Preferably, a dustproof mesh box is fixedly connected to the top of the liquid cooling plate, and the infusion pump, liquid guide tube, round box, transmission shaft, fan blades, air guide duct and air guide plates are all arranged on the inner side of the dustproof mesh box. This not only enables the heat dissipation structure in the heat dissipation mechanism to always operate in a clean environment to reduce the interference of dust on heat dissipation, but also can protect the infusion pump and the heat dissipation structure in the heat dissipation mechanism, thereby reducing the probability of failure of the heat dissipation device.

[0015] The beneficial effects of the utility model are:

[0016] The heat dissipation mechanism can guide the airflow by itself with the help of the flow force of the liquid-cooling medium to dissipate the heat of the liquid-cooling medium passing through, which effectively reduces the temperature of the liquid-cooling medium to ensure that the liquid-cooling medium entering the serpentine liquid guide cavity can always absorb heat, thereby achieving the heat dissipation effect of the charging power supply, and this does not require the installation of an independent power source for the fan blades to achieve good energy-saving effects.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5As shown, a liquid-cooled charging power supply heat dissipation device includes: a liquid cooling plate 1 and an infusion pump 2, the infusion pump 2 is fixedly connected to the liquid outlet of the liquid cooling plate 1; a heat dissipation mechanism 3, the heat dissipation mechanism 3 is fixedly connected and communicated between the liquid outlet of the infusion pump 2 and the liquid inlet of the liquid cooling plate 1, the liquid cooling plate 1 includes a copper alloy plate, a serpentine liquid guide cavity is opened inside the copper alloy plate, the two ends of the serpentine liquid guide cavity are respectively connected to the infusion pump 2 and the liquid guide tube 31, the inside of the serpentine liquid guide cavity, the infusion pump 2, the liquid guide tube 31 and the round box 32 are all filled with a liquid cooling medium, the liquid cooling medium can be water or heat transfer oil, the specific material needs to be selected according to demand, and it will not be repeated here.

[0025] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the heat dissipation mechanism 3 includes a liquid guide tube 31 fixedly connected and connected between the liquid outlet end of the infusion pump 2 and the liquid inlet end of the liquid cooling plate 1, the surface of the liquid guide tube 31 is fixedly connected and connected with a round box 32, the inside of the round box 32 is rotatably connected with a transmission shaft 33, one end of the transmission shaft 33 passes through the outside of the round box 32 and is rotatably connected to the liquid cooling plate 1, the surface of the transmission shaft 33 is fixedly connected with a liquid guide sheet 34, and the surface of the transmission shaft 33 is fixedly connected with a fan blade 35; the center point of the round box 32 coincides with the axis line of the transmission shaft 33, and the center point of the round box 32 and the axis line of the transmission shaft 33 are both arranged above the liquid guide tube 31; the number of the liquid guide sheets 34 is not less than six, and the liquid guide sheets 34 are arranged around the axis line of the transmission shaft 33 in an arc shape. The surface of the transmission shaft 33 is annularly distributed; the surface of the liquid guide tube 31 is fixedly connected with an air guide tube 36 which is evenly distributed and not connected to the inside of the liquid guide tube 31, and the axis of the air guide tube 36 is parallel to the axis of the transmission shaft 33; the top of the liquid cooling plate 1 is fixedly connected with evenly distributed air guide plates 37, and the air guide plates 37 are arranged between the fan blades 35 and the air guide tube 36; the surface of the transmission shaft 33 is fixedly connected with a sealed bearing 38, and the sealed bearing 38 is embedded and installed in the inside of the round box 32; the top of the liquid cooling plate 1 is fixedly connected with a dustproof mesh box 39, and the infusion pump 2, the liquid guide tube 31, the round box 32, the transmission shaft 33, the fan blades 35, the air guide tube 36 and the air guide plates 37 are all arranged on the inner side of the dustproof mesh box 39.

[0026] When the utility model is used, the staff needs to attach one end of the liquid cooling plate 1 without the structure installed to the heating part of the charging power source and fix it at this position in advance. At this time, the copper alloy plate can continuously absorb the heat generated at this position. Then the staff manually turns on the infusion pump 2. The infusion pump 2 draws the liquid cooling medium inside the liquid guiding tube 31 into the serpentine liquid guiding cavity. The serpentine liquid guiding cavity guides the liquid cooling medium back to the liquid guiding tube 31. In the process of the liquid cooling medium passing through the serpentine liquid guiding cavity, the liquid cooling medium can take away the local heat of the copper alloy plate near the serpentine liquid guiding cavity, so that the temperature of the copper alloy plate is reduced, thereby ensuring that the copper alloy plate can always absorb the heat from the heating part of the charging power source, thereby achieving a good heat dissipation effect.

The liquid guide plate 34 drives the transmission shaft 33 to rotate, and the transmission shaft 33 drives the fan blades 35 to rotate. The fan blades 35 stir the surrounding air to form an airflow and guide the airflow in the direction of the liquid guide tube 31. In the process of the airflow passing through the liquid guide tube 31 or the air guide tube 36, the airflow can take away the heat on the surface of the liquid guide tube 31 or the air guide tube 36 in contact with it, so that the liquid guide tube 31 or the air guide tube 36 can continuously absorb the heat in the liquid-cooling medium passing through, which effectively reduces the temperature of the liquid-cooling medium to ensure that the liquid-cooling medium entering the serpentine liquid guide cavity can always absorb heat, thereby achieving the heat dissipation effect of the charging power supply, and the fan blades 35 are driven by themselves through the flow of the liquid cooling medium, which does not require the installation of an independent power source for the fan blades 35 to achieve a good energy-saving effect.

[0028] It should be noted that the infusion pump 2 and the sealed bearing 38 in the above description are both relatively mature devices in the existing technology. The specific model can be selected according to actual needs. At the same time, the infusion pump 2 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
