Description

Technical Field

[0001] This utility model relates to the field of new energy vehicles, and in particular to a structure for reducing water flow noise in a coolant flow channel plate for new energy vehicles. Background Technology

[0002] In the design and application of flow channel plates, the water pump, as the core power component for coolant circulation, directly affects the overall system performance due to the rationality of its inlet and outlet flow channels. In existing flow channel plate layout designs within the industry, there is an inherent height difference between the water pump inlet and outlet. Furthermore, to accommodate the structural requirements of the hand-held water pump, the water pump inlet flow channel of the flow channel plate is typically designed as a single-layer structure. Due to this height difference and the limitation imposed by the inlet flow channel layout, the water pump base outlet of the flow channel plate can only be located above the water pump base inlet flow channel, resulting in a staggered arrangement between the outlet and inlet flow channels.

[0003] This arrangement has led to two persistent key technical problems: On the one hand, there's the noise issue: the noisiest part of the flow channel plate is at the pump outlet. The existing flow channel plate's pump base outlet is too high, resulting in a large water drop and excessive noise. On the other hand, there's the flow resistance issue: because the existing flow channel plate's pump base outlet is too high, turbulence occurs at the pump outlet, increasing flow resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for reducing water flow noise in a coolant flow channel plate for new energy vehicles, so as to solve the problems of high noise and reduced flow resistance mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A structure for reducing water flow noise in a coolant flow channel plate for new energy vehicles includes a flow channel plate one, wherein: A water pump assembly is provided on the side of the flow channel plate one, and a flow channel plate two is provided on the side of the flow channel plate one away from the water pump assembly. The water pump assembly and the flow channel plate two are arranged correspondingly and enclose each other to form a noise reduction channel.

[0006] Preferably, the water pump assembly includes a water pump base, which is embedded and connected to one side of the flow channel plate.

[0007] Preferably, the pump base and the flow channel plate together form an installation cavity, and the pump base is provided with a pump base inlet and a pump base outlet, and the installation cavity is interconnected with the pump base inlet and the pump base outlet respectively.

[0008] Preferably, a water pump body is detachably inserted and installed in the mounting cavity. The water pump body has a water pump outlet and a water pump inlet. The water pump outlet corresponds one-to-one with the water pump base outlet and is sealed and connected. The water pump inlet corresponds one-to-one with the water pump base inlet and is sealed and connected.

[0009] Preferably, the outlet of the water pump base is provided with a flow channel compensation boss, which is embedded in the flow channel plate 2, and the flow channel compensation boss cooperates with the inner wall of the outlet of the water pump base to form a gradually decreasing flow channel.

[0010] Preferably, the side of the flow channel compensation boss away from the flow channel plate is arc-shaped.

[0011] Preferably, the flow channel compensation boss, the flow channel plate II, and the water pump base together form a noise reduction channel.

[0012] The beneficial effects of this utility model are: 1. A gradual flow channel is formed by the cooperation of the flow channel compensation boss with the inner wall of the water pump base outlet to gradually reduce the water pump outlet height, thereby reducing noise. In addition, because the existing flow channel plate water pump base outlet flow channel height is too high, turbulence occurs at the water pump outlet position, thereby increasing flow resistance. This design scheme sets the flow channel compensation boss in the water pump base outlet flow channel to reduce the water pump outlet height, thereby reducing flow resistance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] See Figures 1-5 This utility model provides a structure for reducing water flow noise in a coolant flow channel plate for new energy vehicles, including a flow channel plate 2, wherein: The side of the flow channel plate 2 is provided with a water pump assembly 3, and the side of the flow channel plate 2 away from the water pump assembly 3 is provided with a flow channel plate 4. The water pump assembly 3 and the flow channel plate 4 are arranged correspondingly and enclose each other to form a noise reduction channel.

[0016] The water flow passing through the water pump assembly 3 will cooperate with the noise reduction channel enclosed by the flow channel plate 4, reducing the sound of the water flow and reducing flow resistance.

[0017] The flow channel plate 2 provides mounting points for the water valve 21 and the water pump body 35. The water pump body 35 and the water valve 21 are threadedly connected to the M4 nut insert of the flow channel plate 2 by M4 bolts. The plate heat exchanger is threadedly connected to the M6 ​​nut insert of the flow channel plate 2 by M6 bolts and provides a passage for the coolant system.

[0018] Specifically, the water pump assembly 3 includes a water pump base 31, which is embedded and connected to the side of the flow channel plate 2.

[0019] Specifically, the pump base 31 and the flow channel plate 4 together form an installation cavity 32. The pump base 31 is provided with a pump base inlet 33 and a pump base outlet 34. The installation cavity 32 is interconnected with the pump base inlet 33 and the pump base outlet 34 respectively.

[0020] Specifically, a water pump body 35 is detachably inserted and installed in the mounting cavity 32. The water pump body 35 is provided with a water pump outlet 351 and a water pump inlet 352. The water pump outlet 351 corresponds one-to-one with the water pump base outlet 34 and is sealed and connected. The water pump inlet 352 corresponds one-to-one with the water pump base inlet 33 and is sealed and connected.

[0021] The water flow that enters through the water pump base inlet 33 enters the water pump inlet 352 of the water pump body 35, and then enters the water pump body 35, thereby being discharged from the water pump outlet 351 of the water pump body 35.

[0022] Specifically, the pump base outlet 34 is provided with a flow channel compensation boss 341, which is embedded in the flow channel plate 4, and the flow channel compensation boss 341 cooperates with the inner wall of the pump base outlet 34 to form a gradually decreasing flow channel.

[0023] Specifically, the side of the flow channel compensation boss 341 away from the flow channel plate 4 is arc-shaped.

[0024] When the discharged water flows out, it will first touch the highest point of the flow channel compensation boss 341. Since the flow channel compensation boss 341 and the inner wall of the water pump base outlet 34 cooperate to form a gradual flow channel, the water pump outlet height is gradually reduced, thereby reducing the noise of the water flow and reducing the flow resistance.

[0025] The flow channel compensation boss 341 is arranged in the flow channel of the pump base outlet 34 of the flow channel plate. It gradually reduces the height of the pump outlet 351 as the flow channel conforms to the shape, and finally flows into the main flow channel of the flow channel plate.

[0026] Specifically, a water valve 21 is provided on the side of the flow channel plate 2.

[0027] Specifically, the upper surface of the flow channel plate 2 is provided with a water-side flow channel plate 1.

[0028] Specifically, the flow channel compensation boss 341, the flow channel plate 4, and the water pump base 31 together form a noise reduction channel.

[0029] Working principle of this utility model: In use, the water flow entering through the pump base inlet 33 enters the pump inlet 352 of the pump body 35, and then enters the pump body 35, thus being discharged from the pump outlet 351 of the pump body 35. When the discharged water flow first touches the highest point of the flow channel compensation boss 341, the flow channel compensation boss 341 and the inner wall of the pump base outlet 34 form a gradual flow channel, so as to gradually reduce the water pump outlet height, reduce the noise of the water flow, and reduce the flow resistance.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
