[0046] Example

[0047] Please refer to Figure 1 , this embodiment provides a charging pile liquid cooling module 300, which can manage the temperature of the charging gun line.

[0048] In this embodiment, the charging pile liquid cooling module includes a mounting body 311, a radiator 313, a heat exchange fan 315, a water pump 317 and an expansion kettle 100. The radiator 313, the expansion kettle 100 and the water pump 317 are fixedly mounted on the mounting body 311. The heat exchange fan 315 is mounted on the radiator 313 and is configured to dissipate heat from the radiator 313. The operation of the water pump 317 can form a heat exchange cycle for the heat exchange medium. The cold heat exchange medium in the expansion kettle 100 is sent into the heat exchange pipeline in the charging gun line through the water pump 317. After heat exchange, it flows into the radiator 313 for cooling, and then flows back to the expansion kettle 100 to achieve circulation.

[0049] Please refer to Figure 2 and Figure 3In this embodiment, the expansion kettle 100 includes a kettle body 110 and a guide plate 131. The kettle body 110 has a receiving chamber 111 and a liquid inlet 113 and a liquid outlet 115 connected to the receiving chamber 111. The guide plate 131 is arranged in the receiving chamber and is arranged corresponding to the liquid inlet 113. The liquid flowing into the receiving chamber 111 from the liquid inlet 113 can flow downward along the guide plate 131.

[0050] In this embodiment, a guide plate 131 corresponding to the liquid inlet 113 is arranged in the accommodating chamber 111 of the kettle body 110. The liquid column of the liquid inlet 113 will tilt and impact the guide plate 131 under the action of gravity, and flow along the wall to the liquid surface of the original heat exchange medium in the accommodating chamber 111. This can weaken the mechanical energy of the liquid column, thereby reducing the impact force of the liquid column on the liquid surface, which is conducive to reducing the amount of bubbles carried by the heat exchange medium. Even if a small amount of bubbles are brought in, the bubbles will float on the upper layer of the liquid surface, and the bubbles can be quickly removed by relying on the buoyancy of the bubbles themselves and the fluidity of the fluid. In addition, the guide plate 131 also increases the length of the flow channel, providing ample space for gas-liquid separation.

[0051] In this embodiment, the kettle body 110 is in the shape of a quadrangular prism, including a bottom plate 117, a side plate 119 surrounding the bottom plate 117, and a top plate 121. The bottom plate 117, the side plate 119 and the top plate 121 together form a receiving chamber 111. Generally, a liquid adding port is provided on the top plate 121, and a kettle cover 123 is installed on the liquid adding port. The kettle cover 123 has a breathable valve. After the expansion kettle 100 reaches a preset pressure, the breathable valve will open to release pressure to avoid excessive pressure in the expansion kettle 100.

[0052] Of course, in some other embodiments of the present application, the shape of the kettle body 110 may also be other shapes, such as a spherical shape or an irregular shape.

[0053] Please refer to Figure 2 and Figure 3 In this embodiment, the liquid inlet 113 is arranged on the side wall of the kettle body 110, and is close to the top wall of the kettle body 110. That is, the liquid inlet 113 is arranged at a position on the side plate 119 close to the top plate 121. The guide plate 131 is extended in the height direction and is arranged in the accommodating cavity 111, and the guide plate 131 is connected to the bottom plate 117 (the bottom plate 117 has been led out before and can be used directly, which is clearer than the bottom wall). The projection of the liquid inlet 113 on the side wall where the liquid inlet 113 is set and the projection of the guide plate 131 on the side wall where the liquid inlet 113 is set at least partially overlap. In this way, the liquid column formed by the heat exchange medium flowing in from the liquid inlet 113 will impact on the guide plate 131 and flow downward along the side wall of the guide plate 131.

[0054] In this embodiment, the guide plate 131 is vertically arranged and tilted in the horizontal direction toward the liquid inlet 113. In this application, the guide plate 131 is tilted in the horizontal plane, which can better guide the flow and reduce the generation of bubbles.

[0055] It should be noted that the horizontal direction here is inclined toward the direction of the liquid inlet 113, which can be understood as the guide plate and the liquid inlet 113 are set at an angle, and the value range of the angle is approximately 15°-75°, and 45° can be selected. The guide plate 131 is inclined so that the liquid column with the liquid inlet 113 will not directly hit the guide plate 131, but will be dispersed along the width direction of the guide plate 131, and then flow downward along the guide plate 131, so as to reduce the generation of bubbles.

[0056] In this embodiment, the projection of the liquid inlet 113 on the side plate 119 where the liquid inlet 113 is set is included in the projection of the guide plate 131 on the side plate 119 where the liquid inlet 113 is set, so that the liquid column flowing into the liquid inlet 113 can flow downward along the guide plate.

[0057] Secondly, in some other embodiments of the present application, the liquid inlet and the guide plate may be partially offset, and the guide plate 131 may be slightly inclined.

[0058] In this embodiment, a partition plate 133 is provided on one side of the guide plate 131 away from the liquid inlet 113. The partition plate 133 is vertically arranged and connected to the guide plate 131. The partition plate 133 and the guide plate 131 cooperate to separate the accommodating chamber 111 into a first chamber 135 and a second chamber 137, wherein the first chamber 135 is in communication with the second chamber 137. The liquid inlet 113 is in communication with the first chamber 135, and the liquid outlet 115 is in communication with the second chamber 137.

[0059] In this embodiment, a first chamber 135 and a second chamber 137 are provided, and the liquid inlet 113 is communicated with the first chamber 135 , and the liquid outlet 115 is communicated with the second chamber 137 , so that bubbles can be isolated in the first chamber 135 .

[0060] In the embodiment, the partition plate and the guide plate are integrally formed, and a folding angle is formed between the two by a bending process, so that the forming process is simple.

[0061] Of course, in other embodiments, the partition plate and the guide plate may also be formed separately and then fixedly connected, and the connection methods include welding, clamping, bonding, etc.

[0062] In this embodiment, a first gap 139 is formed between the side of the guide plate 131 away from the partition plate 133 and the side wall where the liquid inlet 113 is provided, and a second gap 141 is formed between the side of the partition plate 133 away from the guide plate 131 and the side plate 119. The first chamber 135 and the second chamber 137 are connected through the first gap 139 and the second gap 141. By arranging the first gap 139 and the second gap 141 on both sides, the two sides converge, and the vortex can be effectively eliminated.

[0063] Please refer to Figure 2 and Figure 3 In this embodiment, the first gap 139 and the second gap 141 gradually decrease from the bottom plate 117 to the top plate 121. This helps to ensure that there is enough flow channel area at the low liquid level, and can better intercept bubbles from entering the second chamber 137 at the high liquid level. The low liquid level and the high liquid level here are a set of relative descriptions distinguished relative to the liquid surface, and the low liquid level is closer to the bottom plate 117, while the high liquid level is closer to the liquid surface.

[0064] In this embodiment, the liquid outlet 115 is disposed on the bottom wall of the kettle body 110 and corresponds to the second chamber 137. This can prevent bubbles from flowing out of the liquid outlet 115. The liquid outlet 115 is provided with a filter, which can filter the heat exchange medium.

[0065] In the present embodiment, the guide plate 131 is a straight plate. Of course, in some other embodiments of the present application, the guide plate 131 may also be configured as an arc plate, for example, bent in the width direction to form an arc surface.

[0066] In this embodiment, the expansion kettle 100 further includes a liquid level sensor 151, which is disposed in the second chamber 137. Since the liquid level fluctuation in the second chamber 137 is small, installing the liquid level sensor 151 in the second chamber 137 can make the measurement more accurate.

[0067] Specifically, the top plate 121 is provided with an opening, and the liquid level sensor 151 is installed in the opening and extends into the second chamber 137 .

[0068] In this embodiment, the expansion kettle 100 further includes a valve 153. The bottom wall of the expansion kettle 100 is provided with a liquid discharge port communicating with the accommodating chamber 111. The valve 153 is installed at the liquid discharge port. This facilitates liquid discharge during maintenance.

[0069] See also Figures 1 to 4In this embodiment, the charging pile liquid cooling module 300 also includes a connection block 330. The connection block 330 is provided with a first flow channel 331 and a second flow channel 333 that are independent of each other, and the connection block 330 is provided with a first installation port 335, a first pipe connection port 337, and a second pipe connection port 339 that are connected to the first flow channel 331. The connection block 330 is also provided with a second installation port 341, a third pipe connection port 343, and a fourth pipe connection port 345 that are connected to the second flow channel 333. The first installation port 335 is installed with a temperature and pressure sensor, and the second installation port 341 is installed with a temperature sensor. The liquid outlet 115 is connected to the inlet of the water pump 317 through the first pipe 347, the outlet of the water pump 317 is connected to the first pipe connecting port 337 through the second pipe 349, the second pipe connecting port 339 is configured to be connected to the inlet of the heat exchange pipeline in the charging gun line of the charging pile, the third pipe connecting port 343 is configured to be connected to the outlet of the heat exchange pipeline in the charging gun line of the charging pile, the fourth pipe connecting port 345 is connected to the inlet of the radiator 313 through the third pipe 351, and the outlet of the radiator 313 is connected to the liquid inlet 113 through the fourth pipe 353.

[0070] Of course, in some other embodiments of the present application, the temperature and pressure sensor may be adjusted to a temperature sensor, or the temperature sensor may be replaced by a temperature and pressure sensor according to needs.

[0071] The beneficial effects of the expansion kettle 100 and the charging pile liquid cooling module provided by the embodiment of the utility model include:

[0072] In this embodiment, a guide plate 131 is arranged in the receiving cavity 111 of the pot body 110 corresponding to the liquid inlet 113. The liquid column at the liquid inlet 113 will tilt and impact the guide plate 131, and flow into the liquid surface by adhering to the wall, which greatly weakens the mechanical energy of the liquid column, reduces the impact force of the liquid column on the liquid surface, and reduces the amount of bubbles carried at the source. Even if a small amount of bubbles are brought in, they will float on the upper layer of the liquid surface, and the bubbles can be quickly removed by relying on their own buoyancy and fluidity. Secondly, the guide plate 131 also increases the length of the flow channel, providing ample space for gas-liquid separation.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
