Description

Technical Field

[0001] This utility model relates to the field of mobile charging technology, specifically to a liquid-cooled mobile charging robot. Background Technology

[0002] Chinese patent application number 202323665451.0 discloses an integrated water-cooling system in which the main circuit inlet of the water tank is connected to the outlet of the thermal management unit, and a cooling water pump is located between the main circuit inlet of the water tank and the outlet of the thermal management unit. An energy storage cooling component is located at the energy storage module, and a converter cooling component is located at the DC-DC conversion module. These components are sequentially connected between the main circuit outlet of the water tank and the inlet of the thermal management unit. A charging gun cooling circuit is located at the charging gun and connected to the water tank, enabling temperature regulation of various modules within the mobile charging vehicle. This integrated water cooling for the chassis power converter and charging gun avoids the need for separate air cooling and multiple small water cooling circuits, reducing the cooling cost of the mobile charging vehicle. Placing the water pump at the main circuit inlet increases the water tank pressure and flow rate, preventing backflow in the charging gun cooling circuit and improving the cooling effect.

[0003] Chinese Patent Application No. 202411082497.6 discloses a liquid cooling system for mobile charging vehicles, relating to the field of mobile charging vehicle technology. The system includes a charging compartment and battery boxes. A cooling box is installed inside the charging compartment, and a baffle plate inside the cooling box divides it into a cooling chamber and a circulation chamber. Coolant is placed in the cooling chamber. Multiple battery boxes are mounted on a mounting frame, which is immersed in the coolant. A cooling plate is installed in the circulation chamber, and a refrigeration unit is located below the cooling plate. The input end of the refrigeration unit is connected to the top of the cooling plate via an inlet pipe, and the output end of the refrigeration unit is connected to the bottom of the cooling chamber via an outlet pipe. In this invention, the refrigeration unit can cool the coolant and circulate it within the cooling box. As the coolant flows through the battery boxes, it carries away the heat from the battery boxes. Liquid cooling replaces traditional air cooling, improving cooling efficiency, effectively increasing battery density, and enhancing the energy storage capacity of the mobile charging vehicle.

[0004] As can be seen from the above search results, liquid cooling solutions for mobile charging robots are currently quite mature in the market.

[0005] However, Chinese patent application number 202323665451.0 does not disclose its specific cold source; Chinese patent application number 202411082497.6, paragraph 0056, describes that after cooling by the refrigeration unit 9, the cooled liquid flows back into the cooling chamber 5, continuously circulating to cool the battery box 2 and the charging vehicle compartment 1. This liquid cooling method replaces traditional air cooling, improving cooling efficiency and increasing the energy storage capacity of the mobile charging vehicle. Simultaneously, this liquid cooling system effectively reduces overheating of the battery pack inside the battery box 2 during charging and discharging, extending the battery pack's lifespan and enhancing the safety performance of the mobile charging vehicle. In other words, Chinese patent application number 202411082497.6 uses existing commercially available refrigeration units for cooling.

[0006] However, the most common use of mobile charging robots is for charging new energy vehicles during holidays, where the usage environment is relatively concentrated, and the cooling unit consumes the mobile charging robot's own power.

[0007] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] like Figures 1 to 5 As shown, the liquid-cooled mobile charging robot of this utility model includes:

[0029] The vehicle body 1 is equipped with an energy storage module. The method of water cooling for the energy storage module can be referred to Chinese Patent Application No. 202323665451.0. The improvement of this application is not in this respect and will not be described in detail.

[0030] The vehicle body 1 is fixedly installed with an insulated heat exchange box 2; an upper cover 3 and a lower cover 4 are detachably installed on the insulated heat exchange box; a water inlet pipe 5 is installed on the upper cover 3, a drain pipe 6 is installed on the lower cover 4, and a vent pipe 7 is installed on the lower cover 4; the insulated heat exchange box 2 contains a cold source.

[0031] The heat exchange box 2 of this application contains a cold source, which is injected into the heat exchange box 2 by opening the top cover 3. The cold water from the drain pipe 6 enters the energy storage module to cool the battery module. After the temperature rises, the water flows back to the heat exchange box 2 through the inlet pipe 5 for cooling. Since the heat exchange box 2 has a cold preservation function, it can keep the cold source at a low temperature. When the cold source loses its function, it can be added, and the failed cold source can be emptied through the vent pipe 7 to realize the replacement of the cold source.

[0032] It is necessary to explain in detail here that the cold source in this application can be liquid nitrogen, ammonium nitrate or ice. That is, the heat exchange box 2 of this application is filled with pure water. The cold source is placed in the pure water to achieve heat exchange. Since liquid nitrogen will sublimate, it will cause pressure problems. Ammonium nitrate needs to be stored and preserved. In actual use, ice is generally chosen because it is simple to prepare, low in cost, and can be used on a large scale.

[0033] In one embodiment, the heat exchange box 2 is covered with an insulation layer, which can be polyurethane foam, vacuum insulation board, phenolic foam, etc. The heat exchange box 2 can be made of stainless steel, with polyurethane foam coated on the outside of the stainless steel. To ensure aesthetics, a decorative panel is generally covered on the outside of the polyurethane foam.

[0034] In another embodiment, the heat exchange box 2 consists of an inner layer, a vacuum layer, and an outer layer; the inner layer is coated with a metal plating, such as copper, which provides better heat preservation. In other words, the heat exchange box 2 in this solution is a common thermos cup design. While polyurethane foam and phenolic foam have large volumes, and vacuum insulation panels are expensive, in practical use, the thermos cup design is generally preferred due to its lower cost and mature technology.

[0035] The upper cover 3 includes: a liquid distribution chamber 8 and a liquid distribution pipe 9; the water inlet pipe 5 is connected to the liquid distribution chamber 8, and the liquid distribution pipe 9 is connected to the liquid distribution chamber 8; a water leakage hole is provided on the liquid distribution pipe 9.

[0036] It should be explained in detail here that the upper cover 3 is connected to the heat exchange box 2 by threads. Multiple liquid distribution pipes 9 are provided and distributed on the edge of the upper cover 3. The water inlet pipe 5 is located in the middle of the liquid distribution pipes 9. The inner diameter of the liquid distribution pipes 9 is smaller than the inner diameter of the water inlet pipe 5. A liquid distribution block 10 is integrally connected to the upper cover 3. The liquid distribution block 10 is conical. The water inlet pipe 5 is directly opposite the liquid distribution block 10. When the water flow impacts the liquid distribution block 10, the water flow will flow along the conical surface and flow towards the liquid distribution pipes 9. The water flowing into the liquid distribution pipes 9 will flow out through the drain hole.

[0037] It should be further explained that one end of the liquid distribution pipe 9 is connected to the liquid distribution chamber 8, so that water from the liquid distribution chamber 8 flows into the liquid distribution pipe 9. The other end of the liquid distribution pipe 9 is a cut-off end, so that water flows out through the drain hole. In addition, it can prevent ice from entering the liquid distribution pipe 9 and avoid the liquid distribution pipe 9 from being blocked. The water inlet pipe 5, the drain pipe 6, and the vent pipe 7 can be equipped with pump bodies as needed.

[0038] Finally, it should be noted that the lower cover 4 is connected to the heat exchange box 2 via threads; the two heat exchange boxes 2 in this application are set up and covered with a shell only for aesthetic purposes; because the manufacturing process of the heat exchange box 2 is relatively complex and mature, it is not possible to set too many components inside the heat exchange box 2. The upper cover 3 is used to even out the flow, so that the water flows to the edge of the heat exchange box 2 and has more contact with the ice in the heat exchange box 2, thus achieving a better heat exchange effect; the cylindrical part of the heat exchange box 2 can be designed to be detachable from the upper and lower surfaces, making manufacturing simpler.

[0039] Working principle:

[0040] During peak charging periods such as holidays, the top cover 3 is opened to inject ice into the heat exchange box 2. The water cooled by the ice flows through the drain pipe 6 into the energy storage module to cool the battery. Then, the water flows through the inlet pipe 5 into the liquid distribution chamber 8. Under the action of the liquid distribution block 10, the water flows along the conical surface to the liquid distribution pipe 9 and flows out through the drain hole, exchanging heat with the ice and being cooled again.

[0041] Ice is easy to prepare and can effectively cool water under the action of the heat exchange box 2.

[0042] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
