Description

Technical Field

[0001] This utility model relates to the field of automotive valve technology, specifically a water circulation control valve for a new energy vehicle cooling system. Background Technology

[0002] The water circulation control valve of the cooling system of new energy vehicles is a core control component. It is mainly used to adjust the water circulation path (such as switching between large and small circulation) according to the cooling demand. By precisely controlling the flow direction and flow rate of the coolant, it ensures that the power system of new energy vehicles operates at a suitable temperature. It is an important device to ensure the cooling efficiency and operational safety of new energy vehicles.

[0003] Existing water circulation control valves in plug-in hybrid electric vehicle (PHEV) cooling systems have several limitations. Traditional valves often use a single spring as the elastic actuation component. Over time, the spring's elasticity tends to decay, leading to decreased valve response sensitivity and difficulty in accurately controlling the timing of water circulation switching, thus affecting the cooling system's adjustment accuracy. The spring's structural characteristics also result in insufficient stability under high-frequency operation, making it susceptible to deformation or fatigue damage due to vibration, shortening valve lifespan and increasing maintenance costs. Furthermore, the limited elastic force output of traditional components fails to meet the rapid response and high-intensity control requirements of PHEV cooling systems. The lack of effective structural integration design and poor component coordination further reduce the valve's reliability under complex operating conditions, thus limiting the overall performance of the PHEV cooling system. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] This invention provides a water circulation control valve for a new energy vehicle cooling system, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a water circulation control valve for a new energy vehicle cooling system, including a three-way pipe, wherein the bottom inner wall of the three-way pipe is tapered, and further including a valve, wherein the valve is fixedly installed inside the three-way pipe.

[0008] According to one embodiment of the present invention, the valve includes a valve cover, which is tapered and has a through-hole top. The valve cover is fixedly snapped onto the inner wall of the tee pipe.

[0009] According to one embodiment of the present invention, side plates are symmetrically fixedly connected to the lower surfaces of both sides of the valve cover, and bottom rings are fixedly connected to the bottom of the side plates.

[0010] According to one embodiment of the present invention, a drive shaft is fixedly connected to the top inner surface of the valve cover. The drive shaft is vertically arranged, and a copper tube is slidably inserted into the bottom of the drive shaft. The outer surface of the copper tube is slidably connected to the inner surface of the bottom ring. The bottom of the drive shaft is located inside the copper tube, and the inside of the copper tube is filled with paraffin wax.

[0011] According to one embodiment of the present invention, a limiting rod is fixedly connected to the bottom of the copper tube, a lower sealing disc is slidably sleeved on the outer surface of the limiting rod, a spring is fixedly connected to the upper surface of the lower sealing disc, and the top of the spring is fixedly connected to the lower surface of the copper tube.

[0012] According to one embodiment of the present invention, an upper sealing disc is fixedly sleeved on the top outer surface of the copper tube, the side surface of the upper sealing disc is initially pressed and fitted with the inner surface of the valve cover, and an elastic component is fixedly connected to the lower surface of the upper sealing disc.

[0013] According to one embodiment of the present invention, the elastic component includes an upper mounting ring, which is fixedly connected to the lower surface of the upper sealing disc. A lower mounting ring is fixedly connected to the upper surface of the bottom ring, and an elastic sheet is fixedly connected to the upper surface of the lower mounting ring. The elastic sheet is folded, and its top is fixedly connected to the lower surface of the upper mounting ring. Multiple elastic sheets are fixedly spaced around the central axis of the copper tube. A stabilizing ring is fixedly connected through the outer end of the elastic sheet. Two stabilizing rings are fixedly spaced, and multiple elastic sheets are fixedly connected to each other through the stabilizing rings.

[0014] The heat source enters through the horizontal opening in the middle of the three-way pipe. Initially, the upper sealing plate and the valve cover are sealed together, while the lower sealing plate and the bottom of the three-way pipe are open. This means that when the heat source enters the three-way pipe, it is discharged through the bottom opening for small-scale heat dissipation. As the temperature of the heat source gradually increases, the temperature directly impacting the valve body also increases. At this point, the paraffin inside the copper pipe begins to melt under high temperature. Its molten expansion creates high pressure inside the copper pipe, pushing the drive shaft outwards and causing it to gradually detach. The top of the drive shaft is fixedly connected to the valve cover, causing the copper pipe to move downwards relative to the drive shaft. This moves the limit rod at the bottom of the copper pipe downwards. Since the top of the spring is fixedly connected to the bottom of the copper pipe... As the copper pipe moves downward, it drives the spring and the lower sealing plate to move downward in sync. Eventually, the lower surface of the lower sealing plate presses against the inner surface of the bottom of the tee pipe, sealing the bottom of the tee pipe. As the copper pipe moves downward, it also drives the upper sealing plate downward, which in turn compresses the elastic component, thus opening the valve cover. When the bottom of the tee pipe is sealed, its top is opened. At this time, the heat source enters the tee pipe and begins to dissipate heat along its top outlet for large-circuit heat dissipation. When not in operation, the copper pipe loses the impact of the heat source and gradually begins to cool down. The paraffin inside it begins to cool and solidify, which slowly loses the compressive force on the drive shaft, causing the valve body to reset and close the large-circuit heat dissipation again. This achieves automatic large and small-circuit heat dissipation based on the temperature of the heat source when the plug-in hybrid electric vehicle is working.

[0015] (III) Beneficial Effects

[0016] This utility model provides a water circulation control valve for a new energy vehicle cooling system. It has the following beneficial effects:

[0017] The water circulation control valve of this new energy vehicle cooling system uses a combined elastic component instead of a conventional spring body. The elastic sheet provides elasticity to the valve body. The elastic sheet is distributed in a ring shape, which provides better stability than the spring body. The elastic sheet is also folded, so the overall elasticity is higher than that provided by the spring body, making it more stable. In addition, the stabilizing ring set inside the elastic sheet can combine and connect the ring-shaped elastic sheet into a whole, providing higher stability during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] like Figures 1 to 4 As shown, this utility model provides a technical solution: a water circulation control valve for a new energy vehicle cooling system, including a three-way pipe 1, the bottom inner wall of the three-way pipe 1 being tapered, and further including:

[0025] Valve 2 is fixedly installed inside the tee pipe 1.

[0026] Valve 2 includes valve cover 3, which is tapered and has a through-hole top. Valve cover 3 is fixedly snapped onto the inner wall of tee pipe 1.

[0027] Side plates 4 are symmetrically fixedly connected to the lower surfaces of both sides of the valve cover 3, and bottom rings 5 ​​are fixedly connected to the bottom of the side plates 4.

[0028] A drive shaft 6 is fixedly connected to the top inner surface of the valve cover 3. The drive shaft 6 is vertically arranged. A copper tube 7 is slidably inserted into the bottom of the drive shaft 6. The outer surface of the copper tube 7 is slidably connected to the inner surface of the bottom ring 5. The bottom of the drive shaft 6 is located inside the copper tube 7, and the inside of the copper tube 7 is filled with paraffin wax.

[0029] A limiting rod 8 is fixedly connected to the bottom of the copper tube 7. A lower sealing disc 9 is slidably sleeved on the outer surface of the limiting rod 8. A spring 10 is fixedly connected to the upper surface of the lower sealing disc 9. The top of the spring 10 is fixedly connected to the lower surface of the copper tube 7.

[0030] The upper sealing disc 11 is fixedly sleeved on the top outer surface of the copper tube 7. The side surface of the upper sealing disc 11 is initially pressed and fitted with the inner surface of the valve cover 3. An elastic component 12 is fixedly connected to the lower surface of the upper sealing disc 11.

[0031] The elastic component 12 includes an upper mounting ring 13, which is fixedly connected to the lower surface of the upper sealing disc 11. A lower mounting ring 14 is fixedly connected to the upper surface of the bottom ring 5. An elastic sheet 15 is fixedly connected to the upper surface of the lower mounting ring 14. The elastic sheet 15 is folded. The top of the elastic sheet 15 is fixedly connected to the lower surface of the upper mounting ring 13. Multiple elastic sheets 15 are fixedly spaced around the central axis of the copper tube 7. A stabilizing ring 16 is fixedly connected to the outer end of the elastic sheet 15. Two stabilizing rings 16 are fixedly spaced. Multiple elastic sheets 15 are fixedly connected to each other through the stabilizing rings 16.

[0032] During operation, the heat source enters through the horizontal opening in the middle of the three-way pipe 1. Initially, the upper sealing plate 11 and the valve cover 3 are sealed together, while the lower sealing plate 9 and the bottom of the three-way pipe 1 are open. This means that when the heat source enters the three-way pipe 1, it is discharged through the opening at the bottom for small-scale heat dissipation. As the temperature of the heat source gradually increases, the temperature directly impacting the valve body also increases. At this point, the paraffin inside the copper pipe 7 begins to melt under high temperature. Utilizing its molten expansion property, the inside of the copper pipe 7 is under high pressure, which begins to push the drive shaft 6 outwards, causing it to gradually detach. The top of shaft 6 is fixedly connected to valve cover 3, which causes copper pipe 7 to move downward relative to drive shaft 6. This causes the limiting rod 8 at the bottom of copper pipe 7 to move downward. Since the top of spring 10 is fixedly connected to the bottom of copper pipe 7, as copper pipe 7 moves downward, spring 10 and lower sealing disc 9 move downward synchronously. Finally, the lower surface of lower sealing disc 9 presses against the inner bottom surface of the three-way pipe 1, sealing the bottom of the three-way pipe 1. As copper pipe 7 moves downward, it also causes upper sealing disc 11 to move downward, which in turn presses against elastic component 12, thus opening valve cover 3. When the bottom of the three-way pipe 1 is sealed, the valve cover 3 is opened. Its top is open, and the heat source enters the three-way pipe 1 and begins to dissipate heat along its top outlet for large-loop heat dissipation. When not in operation, the copper pipe 7 loses the impact of the heat source and gradually begins to cool down. The paraffin inside it begins to cool and solidify, that is, it slowly loses the squeezing force on the drive shaft 6, causing the valve body to reset and close the large-loop heat dissipation again. This achieves automatic large and small-loop heat dissipation according to the temperature of the heat source when the plug-in hybrid new energy vehicle is working. When the valve body is working, the elastic component 12 is always under high pressure. Conventional valve bodies directly use a spring 10 to replace the elastic component 12. With the increase of use time, the spring... The rapid decrease in elasticity of the spring 10 body leads to a short service life of the valve body and frequent maintenance. This valve body uses a combined elastic component 12 to replace the conventional spring 10 body. The elastic sheet 15 provides elasticity to the valve body. The elastic sheet 15 is distributed in a ring shape, which provides better stability than the spring 10 body. In addition, the elastic sheet 15 is folded, and the overall elasticity is higher than that provided by the spring 10 body, making it more stable in use. At the same time, the stabilizing ring 16 set inside the elastic sheet 15 can combine and connect the ring-shaped elastic sheet 15 into a whole, providing higher stability during operation.
