[0002] With the increasing popularity of automatic transmission cars, the problem that the heat generated by automatic transmissions is greater than that of conventional manual transmissions has gradually been taken seriously by various automobile manufacturers. Existing products mostly use thermal expansion materials to throttle the oil circuit, thereby achieving the purpose of controlling the system temperature.

[0003] However, due to the valve body design and the characteristics of the expansion material itself, the heat dissipation is too slow, making the thermostatic valve respond slowly to system temperature changes, seriously affecting the temperature control effect. Summary of the invention

[0004] The main purpose of the present invention is to provide a thermostatic valve to solve the problem in the prior art that the traditional thermostatic system dissipates heat too slowly and the thermostatic valve responds slowly to the temperature change of the system, which seriously affects the thermostatic effect.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a thermostatic valve, comprising: a thermostatic valve body, in which a plurality of fluid channels are arranged; a thermal expansion component, which is arranged in the thermostatic valve body; wherein the plurality of fluid channels include at least a heat dissipation channel and a speed change channel, the heat dissipation channel is connected to a radiator, and a thermal expansion component is arranged inside the speed change channel.

[0006] Furthermore, a fluid inlet and multiple fluid outlets are provided on the thermostatic valve body, and the fluid inlet and multiple fluid outlets are respectively connected to form multiple fluid channels; the thermostatic valve also includes a diverter, which is installed in the thermostatic valve body and at the intersection of multiple fluid channels.

[0007] Furthermore, a fluid inlet and two fluid outlets are provided on the thermostatic valve body, and the two fluid outlets include a first fluid outlet and a second fluid outlet; the fluid inlet is connected with the first fluid outlet to form a heat dissipation channel, and the fluid inlet is connected with the second fluid outlet to form a speed change channel, and the diverter is installed at the intersection of the heat dissipation channel and the speed change channel.

[0008] Furthermore, the heat dissipation channel and the speed change channel are arranged adjacent to each other in a portion of the flow divider, and the thermal expansion assembly is installed on the flow divider.

[0009] Furthermore, a portion of the flow divider in the speed change channel is provided with a plurality of speed change flow holes, and the thermal expansion component blocks part of the speed change flow holes after thermal expansion.

[0010] Furthermore, the flow divider is made of heat-conducting material, the thermal expansion assembly surrounds the flow divider, and the heat dissipation channel is at least partially located in the thermal expansion assembly.

[0011] Furthermore, the multiple speed-changing flow holes include a group of multiple first flow holes surrounding the heat dissipation channel and a group of multiple second flow holes surrounding the heat dissipation channel. The multiple second flow holes are located outside the multiple first flow holes, and the aperture of the second flow holes is larger than the aperture of the second flow holes.

[0012] Furthermore, the thermal expansion component includes a thermal expansion part made of a thermal expansion material and an elastic part made of an elastic material, and both the thermal expansion part and the elastic part have multiple layers and are alternately arranged.

[0013] Furthermore, the thermal expansion component is a columnar structure, and the thermal expansion part and the elastic part are alternately stacked in the axial direction, so that the radial deformation of the thermal expansion component after being heated is greater than the axial deformation.

[0014] Furthermore, the flow divider is installed in the thermostatic valve body through a valve sleeve, a sealing ring is provided between the valve sleeve and the thermostatic valve body, and the valve sleeve is installed on the thermostatic valve body through a retaining spring and a retaining ring.

[0015] By applying the technical solution of the present invention, when the temperature of the fluid in the speed change channel is too high, the thermal expansion component arranged in the speed change channel will expand and block part of the speed change channel, so that the fluid flowing through the speed change channel becomes less, and more fluid flows to the heat dissipation channel, and the heat dissipation channel is connected to the radiator, so that more fluid can be cooled down. When the temperature of the fluid is reduced, the thermal expansion component shrinks, so that more fluid can pass through the speed change channel, reducing the fluid flowing through the radiator, so that the fluid temperature is kept within the required range for normal operation. The thermostatic valve can respond in time under the action of the thermal expansion component when the temperature of the fluid rises, so as to cool down and ensure that the fluid temperature required by the device where the thermostatic valve is located is always at a normal level. And the above process does not need to be controlled, and can be carried out autonomously under the characteristics of the thermal expansion material. Therefore, the above thermostatic valve can increase the heat dissipation speed of the thermostatic system in which it is located, improve the error response speed of the thermostatic valve, and make the thermostatic effect stronger. The technical solution of the present invention effectively solves the problem that the traditional thermostatic system in the prior art dissipates heat too slowly, and the thermostatic valve responds slowly to the temperature change of the system, which seriously affects the thermostatic effect.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0034] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0035] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for clarity, the thickness of the layers and regions is enlarged, and the same reference numerals are used to represent the same devices, so their description will be omitted.

[0036] like Figures 1 to 6 As shown, a thermostatic valve in this embodiment includes a thermostatic valve body 10 and a thermal expansion assembly 20. A plurality of fluid channels are arranged in the thermostatic valve body 10. The thermal expansion assembly 20 is arranged in the thermostatic valve body 10. Among them, the plurality of fluid channels include at least a heat dissipation channel 14 and a speed change channel 15, the heat dissipation channel 14 is connected to the radiator 50, and the thermal expansion assembly 20 is arranged inside the speed change channel 15.

[0037] By applying the technical solution of this embodiment, when the temperature of the fluid in the speed change channel 15 is too high, the thermal expansion component 20 arranged in the speed change channel 15 will expand and block part of the speed change channel 15, so that the fluid flowing through the speed change channel 15 becomes less, and more fluid flows to the heat dissipation channel 14, and the heat dissipation channel 14 is connected to the radiator 50, so that more fluid can be cooled. When the temperature of the fluid is reduced, the thermal expansion component 20 shrinks, so that more fluid can pass through the speed change channel 15, reducing the fluid flowing through the radiator 50, so that the fluid temperature is kept within the required range for normal operation. The thermostatic valve can respond in time under the action of the thermal expansion component 20 when the temperature of the fluid rises, thereby cooling down, ensuring that the fluid temperature required by the device where the thermostatic valve is located is always at a normal level. And the above process does not need to be controlled, and can be carried out autonomously under the characteristics of the thermal expansion material. Therefore, the above thermostatic valve can increase the heat dissipation speed of the thermostatic system in which it is located, improve the error response speed of the thermostatic valve, and make the thermostatic effect stronger. The technical solution of this embodiment effectively solves the problem in the prior art that the traditional temperature control system dissipates heat too slowly, and the temperature control valve responds slowly to changes in system temperature, which seriously affects the temperature control effect.

[0038] like Figures 1 to 6 As shown, in the technical solution of this embodiment, a fluid inlet 11 and a plurality of fluid outlets are provided on the thermostatic valve body 10, and the fluid inlet 11 and the plurality of fluid outlets are respectively connected to form a plurality of fluid channels. The thermostatic valve further comprises a flow divider 30, which is installed in the thermostatic valve body 10, and the flow divider 30 is installed at the intersection of the plurality of fluid channels. The fluid inlet 11 in the above structure is preferably provided as one, so that a plurality of fluid channels can share a fluid inlet 11 and be diverted through the flow divider 30, and the provision of the flow divider 30 can better provide the thermal expansion assembly 20.

[0039] like Figures 1 to 6 As shown, in the technical solution of this embodiment, a fluid inlet 11 and two fluid outlets are provided on the thermostatic valve body 10, and the two fluid outlets include a first fluid outlet 12 and a second fluid outlet 13. The fluid inlet 11 is connected with the first fluid outlet 12 to form a heat dissipation channel 14, and the fluid inlet 11 is connected with the second fluid outlet 13 to form a speed change channel 15. The flow divider 30 is installed at the intersection of the heat dissipation channel 14 and the speed change channel 15. The above structure can flow more fluid from the heat dissipation channel 14 when the thermal expansion component 20 in the speed change channel 15 expands due to heat, so that more fluid can be dissipated. When the fluid after heat dissipation passes through the thermal expansion component 20 again, the thermal expansion component 20 can shrink and restore its deformation. Such a setting can spontaneously control the heat dissipation through the change of fluid temperature, and the control is sensitive and the response speed is fast. At the same time, the above structure can make the thermostatic valve more compact and reduce the occupied space of the thermostatic system.

[0040] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the heat dissipation channel 14 and the speed change channel 15 are arranged adjacent to each other in the part of the diverter 30, and the thermal expansion assembly 20 is installed on the diverter 30. The above structure can make the thermal expansion assembly 20 more sensitive. At the same time, after the thermal expansion assembly 20 is installed on the diverter 30, it can be disassembled, cleaned and replaced by disassembling and assembling the diverter assembly, thereby reducing maintenance costs.

[0041] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the flow divider 30 is provided with a plurality of speed change flow holes in the speed change channel 15, and the thermal expansion component 20 blocks part of the speed change flow holes after thermal expansion. The above structure can make the flow control of the speed change channel 15 more precise.

[0042] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the flow divider 30 is made of heat-conducting material, the thermal expansion assembly 20 surrounds the flow divider 30, and the heat dissipation channel 14 is at least partially located in the thermal expansion assembly 20. The above structure allows the fluid in the heat dissipation channel 14 to also exchange heat with the thermal expansion assembly 20, and such a setting can further improve the sensitivity of the thermostatic valve.

[0043] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the plurality of speed-changing circulation holes include a group of a plurality of first circulation holes 31 surrounding the heat dissipation channel 14 and a group of a plurality of second circulation holes 32 surrounding the heat dissipation channel 14, the plurality of second circulation holes 32 are located outside the plurality of first circulation holes 31, and the aperture of the second circulation holes 32 is larger than the aperture of the second circulation holes 32. The above structure can further improve the accuracy of flow control of the speed-changing channel 15. When the thermal expansion component 20 expands less, the flow limit is smaller, and when the expansion is large, the flow limit is larger, or even the speed-changing channel 15 is directly blocked.

[0044] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the thermal expansion component 20 includes a thermal expansion part 21 made of a thermal expansion material and an elastic part 22 made of an elastic material, and the thermal expansion part 21 and the elastic part 22 both have multiple layers and are alternately arranged. The alternating arrangement of the thermal expansion part 21 and the elastic part 22 in the above structure can limit the expansion direction of the thermal expansion component 20, so that a more precise expansion amount can be formed.

[0045] like Figures 7 to 11 As shown, in the technical solution of this embodiment, the thermal expansion component 20 is a columnar structure, and the thermal expansion part 21 and the elastic part 22 are alternately stacked in the axial direction, so that the radial deformation of the thermal expansion component 20 after being heated is greater than the axial deformation. The above structure can better cooperate with the multiple first flow holes 31 and the multiple second flow holes 32.

[0046] like Fig.12 and 13As shown, in the technical solution of this embodiment, the diverter 30 is installed in the thermostatic valve body 10 through the valve sleeve 40, and a sealing ring 41 is provided between the valve sleeve 40 and the thermostatic valve body 10. The valve sleeve 40 is installed on the thermostatic valve body 10 through a retaining ring 42. The above structure can make the installation of the diverter 30 more stable and reliable. The provision of the sealing ring 41 can improve the sealing between the diverter 30 and the thermostatic valve body 10, and the provision of the retaining ring 42 can make the installation of the diverter 30 more stable on the one hand, and facilitate the disassembly and maintenance of the diverter 30 on the other hand.

[0047] like Fig.12 and 13 As shown, in the technical solution of this embodiment, the heat dissipation channel 14 cooperates with the radiator 50 and the gearbox 60 to form a fluid heat dissipation circuit, and the speed change channel 15 cooperates with the gearbox 60 to form a fluid speed change circuit. When the thermal expansion component 20 is in a contracted state, the fluid will flow through the fluid heat dissipation circuit and the fluid speed change circuit respectively. When the thermal expansion component 20 is in an expanded state, most or even all of the fluid passes through the fluid heat dissipation circuit, so that more fluid is dissipated, thereby ensuring that the temperature of the fluid is at a normal working temperature.

[0048] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when the temperature of the fluid in the speed change channel 15 is too high, the thermal expansion component 20 arranged in the speed change channel 15 will expand and block part of the speed change channel 15, so that the fluid flowing through the speed change channel 15 becomes less, and more fluid flows to the heat dissipation channel 14, and the heat dissipation channel 14 is connected to the radiator 50, so that more fluid can be cooled down, and when the temperature of the fluid is reduced, the thermal expansion component 20 shrinks, so that more fluid can pass through the speed change channel 15, reducing the fluid flowing through the radiator 50, so that the fluid temperature is kept within the required range for normal operation. The thermostatic valve can respond in time under the action of the thermal expansion component 20 when the temperature of the fluid rises, thereby cooling down, ensuring that the fluid temperature required by the device where the thermostatic valve is located is always at a normal level. And the above process does not need to be controlled, and can be carried out autonomously under the characteristics of the thermal expansion material. Therefore, the above thermostatic valve can increase the heat dissipation speed of the thermostatic system in which it is located, improve the error response speed of the thermostatic valve, and make the thermostatic effect stronger. The technical solution of the present invention effectively solves the problem in the prior art that the traditional temperature control system has too slow heat dissipation and the temperature control valve responds slowly to the temperature change of the system, which seriously affects the temperature control effect.
