Description

Technical Field

[0001] This application relates to the field of cooler technology, and more particularly to an oil cooler and a vehicle. Background Technology

[0002] The oil cooler is a crucial component of the engine lubrication and cooling system. Its function is to cool the engine oil during circulation and maintain its temperature within the normal operating range. Oil coolers generally come in two types: air-cooled and water-cooled. Water-cooled coolers utilize the temperature of the coolant to control the oil temperature, thus achieving oil cooling.

[0003] In actual use, different types of coolant may be added due to different user habits. Different coolants have different freezing points. When the temperature reaches the freezing point of the coolant, the coolant will solidify and change from a working fluid to a solid, thus increasing the volume it occupies.

[0004] However, when users use coolants with a higher freezing point, the coolant will solidify because its freezing point is higher than the ambient temperature. This increases its volume and can easily cause the oil cooler to crack, thus affecting the cooling of the engine oil and even the normal use of the vehicle. Summary of the Invention

[0005] In order to solve at least one of the problems mentioned in the background art, this application provides an oil cooler and a vehicle, which aims to solve the problem that when the user uses a coolant with a higher freezing point, the coolant will solidify and increase in volume because the freezing point of the coolant is higher than the ambient temperature, which can easily cause the oil cooler to freeze and crack, thereby affecting the cooling of the oil and even affecting the normal use of the vehicle.

[0006] To achieve the above objectives, in a first aspect, this application provides an oil cooler for use in a vehicle. The oil cooler includes a housing, a cooling core assembly, and a detection assembly. The housing has a receiving cavity for containing a coolant. The cooling core assembly and the detection assembly are both in communication with the receiving cavity. The detection assembly is configured to detect detection information of the type of coolant and send the detection information to the vehicle's controller.

[0007] In the aforementioned oil cooler, optionally, the detection component includes a transmitter / receiver and a refractor, wherein the transmitter / receiver is used to emit and receive light, and the refractor is located on the optical path of the transmitter / receiver.

[0008] Optionally, in the aforementioned oil cooler, the detection component includes a signal transmission element for signal connection with the controller and for sending the detection information to the controller.

[0009] In the aforementioned oil cooler, optionally, the transmitter and receiver include a light emitting module, a light receiving module, and a conversion module. The light emitting module is used to emit light, and the light receiving module is used to receive light.

[0010] The conversion module is electrically connected to at least the light receiving module and the signal transmission device, and is used to convert the light signal into an electrical signal and send it to the controller through the signal transmission device.

[0011] In the aforementioned oil cooler, the refractive element may optionally include a prism.

[0012] In the aforementioned oil cooler, optionally, the housing has a first through hole communicating with the receiving cavity, the transmitting and receiving element of the detection component faces the first through hole, the light emitted by the transmitting and receiving element is directed to the receiving cavity through the first through hole, reflected by the cooling working fluid in the receiving cavity, and then reflected back to the transmitting and receiving element through the first through hole.

[0013] In the aforementioned oil cooler, optionally, the housing has a second through hole, through which the cooling core assembly communicates with the receiving cavity, and the second through hole is opened near the first through hole.

[0014] Optionally, the oil cooler described above may also include a sealing ring, which is disposed at the first through hole and located between the housing and the detection component.

[0015] Secondly, the present invention also provides a vehicle, including a vehicle body, a controller, and an oil cooler, wherein the oil cooler and the controller are both disposed on the vehicle body, the controller is electrically connected to the detection component of the oil cooler, and the controller is configured to receive and process detection information emitted by the oil cooler.

[0016] Optionally, the vehicle described above may also include an alarm device, which is electrically connected to the controller. The controller is configured to acquire the current ambient temperature of the vehicle and the detection information to determine the actual freezing point of the coolant, generate alarm information based on the actual freezing point and the ambient temperature, and the alarm device is configured to issue an alarm action based on the alarm information.

[0017] The present invention provides an oil cooler and a vehicle, wherein the oil cooler is applied to a vehicle and includes a housing, a cooling core assembly, and a detection assembly. The housing has a receiving cavity for containing the coolant. The cooling core assembly and the detection assembly are both connected to the receiving cavity. The detection assembly is configured to detect the type of coolant and send the detection information to the vehicle's controller. By setting the detection assembly to detect the type of coolant added to the oil cooler, it is possible to avoid adding coolants with high freezing points, thereby preventing the coolant from solidifying due to its freezing point being higher than the ambient temperature, which would increase its volume. This fundamentally prevents the coolant from freezing and cracking the oil cooler, reducing the possibility of the oil cooler freezing and cracking, and ensuring the normal operation of the vehicle.

Detailed Implementation

[0045] During vehicle use, different types of coolant can be added to the oil cooler. Different coolants have different freezing points. When the user uses a coolant with a higher freezing point, if the ambient temperature of the vehicle is lower than the freezing point of the coolant, the coolant will solidify, changing from liquid to solid, increasing in volume, and is prone to freezing and cracking the oil cooler, thus affecting the cooling of the oil and even the normal use of the vehicle.

[0046] Based on the aforementioned technical problems, the present invention provides an oil cooler and a vehicle. The oil cooler, applied to a vehicle, includes a housing, a cooling core assembly, and a detection assembly. The housing has a receiving cavity for containing the coolant. The cooling core assembly and the detection assembly are both connected to the receiving cavity. The detection assembly is configured to detect the type of coolant added and send this detection information to the vehicle's controller. By using a detection assembly to detect the type of coolant added to the oil cooler, it is possible to avoid adding coolants with high freezing points. This prevents the coolant from solidifying due to its freezing point being higher than the ambient temperature, thus avoiding volume increase and fundamentally preventing the coolant from freezing and cracking the oil cooler. This reduces the likelihood of the oil cooler freezing and cracking, ensuring the normal operation of the vehicle.

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The implementation details of this application will be described below with reference to the accompanying drawings.

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

[0049] Example 1

[0051] Figure 4 This is a schematic diagram of a vehicle controller processing detection information according to Embodiment 2 of the present invention; Figure 5 This is a schematic diagram of the process of a controller for processing detection information for another vehicle provided in Embodiment 2 of this invention.

[0052] See attached document Figure 1 Appendix Figure 2 As shown, Embodiment 1 of the present invention provides an oil cooler 100, which is applied to a vehicle. The oil cooler 100 includes a housing 110, a cooling core assembly 120, and a detection assembly 130.

[0053] The housing 110 has a receiving cavity 111 for containing the cooling working fluid.

[0054] Understandably, the coolant is used to reduce the temperature of the vehicle's engine and has an anti-corrosion function. After the coolant is added to the containment cavity 111, it can flow to the cooling core assembly 120. The cooling core assembly 120 absorbs heat through the coolant to cool the vehicle's engine, so as to keep the vehicle's engine at a suitable temperature and avoid damage caused by excessive engine temperature, which would affect the use of the vehicle.

[0055] The cooling core assembly 120 and the detection assembly 130 are both connected to the receiving cavity 111.

[0056] It is understood that the cooling core assembly 120 is connected to the receiving cavity 111 so that the cooling medium in the receiving cavity 111 can flow to the cooling core assembly 120, and the detection assembly 130 is connected to the receiving cavity 111 so that the detection assembly 130 can detect the cooling medium in the receiving cavity 111.

[0057] It should be noted that the cooling core assembly 120 may be a structure with multiple fins, a mechanism with circulation pipes, or other structures. The embodiments of this application do not limit the specific structure of the cooling core assembly 120, nor are they limited to the above examples.

[0058] Specifically, the receiving cavity 111 of the housing 110 is connected to at least one opening or pipe. The opening or pipe can be connected to the external environment so that the user can add coolant at the opening or pipe. The opening or pipe can be opened on the housing 110 of the oil cooler 100 or can be set on any structure that connects the opening or pipe. This embodiment does not limit the position, shape or size of the opening or pipe for adding coolant, nor is it limited to the above example.

[0059] The detection component 130 is configured to detect the type of coolant and send the detection information to the vehicle's controller.

[0060] Specifically, the detection method of the detection component 130 can be real-time detection, detection when the user adds the coolant, or detection at intervals. The detection information can be obtained based on the characteristics of the coolant, including but not limited to the coolant's transmittance, density, temperature, viscosity, and color.

[0061] As an optional implementation, the detection component 130 includes a transmitter-receiver 131 and a refractor 132. The transmitter-receiver 131 is used to emit and receive light, and the refractor 132 is located on the optical path of the transmitter-receiver 131.

[0062] The light emitted by the transmitter-receiver 131 is a first light, and the light received by the transmitter-receiver 131 is a second light.

[0063] It is understandable that both the first and second rays pass through the refractor 132 so that the transmitting and receiving components 131 can accurately transmit and receive the rays.

[0064] In this embodiment, the light path is as follows: the transmitter-receiver 131 emits a first light ray, the first light ray passes through the refractor 132, the angle of the first light ray changes, and then it is directed toward the receiving cavity 111 carrying the cooling medium. After passing through the cooling medium, the first light ray changes into a second light ray, the second light ray passes through the refractor 132, the angle of the second light ray changes, and then it is directed toward the transmitter-receiver 131.

[0065] By setting up a transmitter-receiver 131 and obtaining the detection information of the cooling medium based on the light information of the second light passing through the cooling medium, the type of cooling medium can be obtained. This avoids adding a cooling medium with a high freezing point, reducing the possibility of the oil cooler 100 freezing and cracking, thus ensuring the normal use of the vehicle.

[0066] As an optional implementation, the detection component 130 includes a signal transmission element 133, which is used to connect to the controller and send detection information to the controller.

[0067] It is understandable that the signal transmission device 133 can be connected to the controller signal via wired communication, wireless communication, or both. Wireless communication can be one or a combination of several of the following: wireless local area networks (WLAN) (such as wireless fidelity (WiFi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), 2G, 3G, 4G, or 5G.

[0068] As an optional implementation method, such as Figure 2As shown, the transmitter-receiver unit 131 includes a light emitting module 1311, a light receiving module 1312, and a conversion module 1313. The light emitting module 1311 is used to emit light, and the light receiving module 1312 is used to receive light.

[0069] The conversion module 1313 is electrically connected to at least the light receiving module 1312 and the signal transmission device 133, and is used to convert the light signal into an electrical signal and send it to the controller through the signal transmission device 133.

[0070] Specifically, the light emitting module 1311 is used to emit a first light beam, and the light receiving module 1312 is used to receive a second light beam. Specifically, the conversion module 1313 is electrically connected to the light receiving module 1312 to convert the light signal into an electrical signal; the signal transmission component 133 is electrically connected to the conversion module 1313 to send the electrical signal to the controller; the conversion module 1313 can also be electrically connected to the light emitting module 1311 to control the light emitting module 1311 to emit the first light beam.

[0071] It is understandable that the signal transmission unit 133 can send detection information to the controller via wired communication, wireless communication, or both. The specific communication methods have been described above and will not be repeated here.

[0072] As an alternative implementation, the refractive element 132 includes a prism 1321, specifically, the prism 1321 may be a resin prism.

[0073] As an optional implementation, the housing 110 has a first through hole 112 communicating with the receiving cavity 111. The transmitting and receiving component 131 of the detection component 130 faces the first through hole 112. The light emitted by the transmitting and receiving component 131 is directed to the receiving cavity 111 through the first through hole 112, reflected by the cooling working fluid in the receiving cavity 111, and then reflected back to the transmitting and receiving component 131 through the first through hole 112.

[0074] It is understandable that the refractive element 132 can be located in or outside the first through hole 112.

[0075] When the refractive element 132 is located in the first through hole 112, the light path is as follows: the transmitting and receiving element 131 emits a first light ray, the first light ray enters the first through hole 112, passes through the refractive element 132, the angle of the first light ray changes, and then it is directed towards the receiving cavity 111 carrying the cooling medium. After passing through the cooling medium, the first light ray changes into a second light ray, the second light ray enters the first through hole 112, passes through the refractive element 132, the angle of the second light ray changes, and then it is directed towards the transmitting and receiving element 131.

[0076] When the refractive element 132 is located outside the first through hole 112, the light path is as follows: the transmitting and receiving element 131 emits a first light ray, the first light ray passes through the refractive element 132, the angle of the first light ray changes, and it passes through the first through hole 112 and is directed towards the receiving cavity 111 carrying the cooling medium. After passing through the cooling medium, the first light ray changes into a second light ray, the second light ray passes through the second through hole 113, and then passes through the refractive element 132, the angle of the second light ray changes, and then it is directed towards the transmitting and receiving element 131.

[0077] Specifically, the housing 110 may also have a mounting cavity that is connected to the receiving cavity 111. The detection component 130 and the refractive element 132 are both located in the mounting cavity, and the mounting cavity and the receiving cavity 111 are connected through the first through hole 112.

[0078] As an optional implementation, the housing 110 has a second through hole 113, through which the cooling core assembly 120 communicates with the receiving cavity 111. The second through hole 113 is opened near the first through hole 112.

[0079] It is understandable that the cooling medium flows to the receiving cavity 111 through the second through hole 113. By opening the second through hole 113 close to the first through hole 112, compared to other positional relationships, the detection component 130 can quickly acquire light information when the cooling medium is about to flow to the receiving cavity 111 through the second through hole 113, so as to quickly obtain the type of cooling medium.

[0080] It is understood that the first through hole 112 and the second through hole 113 are both formed on the wall of the receiving cavity 111. Specifically, the first through hole 112 and the second through hole 113 can be arranged opposite to each other, or the hole axis of the first through hole 112 and the hole axis of the second through hole 113 can be arranged to intersect, so that the detection component 130 can quickly acquire light information and thus quickly obtain the type of cooling medium.

[0081] It should be noted that the angle between the axis of the first through hole 112 and the axis of the second through hole 113 can be a right angle or other intersecting angles, so that the detection component 130 can acquire light information more quickly.

[0082] As an optional implementation, a sealing ring 140 is also included, which is disposed at the first through hole 112 and located between the housing 110 and the detection component 130.

[0083] Understandably, the sealing ring 140 can enhance the tightness of the connection between the housing 110 and the detection component 130, so as to prevent the cooling working fluid from flowing into the detection component 130 and affecting the use of the detection component 130.

[0084] Specifically, the sealing ring 140 may be located between the refractive element 132 and the housing 110, and on the side of the refractive element 132 away from the transmitter and receiver 131, to prevent the cooling working fluid from flowing into the detection assembly 130.

[0085] It is understood that the sealing ring 140 can be a non-shaped sealing ring 140, and / or the material used to make the sealing ring 140 can be rubber, and / or the sealing ring 140 can be a high-temperature resistant sealing ring 140.

[0086] The oil cooler 100 provided in Embodiment 1 of the present invention is applied to a vehicle and includes a housing 110, a cooling core assembly 120, and a detection assembly 130. The housing 110 has a receiving cavity 111 for containing the coolant. The cooling core assembly 120 and the detection assembly 130 are both connected to the receiving cavity 111. The detection assembly 130 is configured to detect the type of coolant and send the detection information to the vehicle's controller. By setting the detection assembly 130 to detect the type of coolant added to the oil cooler 100, it is possible to avoid adding coolants with high freezing points, thereby preventing the coolant from solidifying due to its freezing point being higher than the ambient temperature, which would increase its volume. This fundamentally prevents the coolant from freezing and cracking the oil cooler 100, reducing the possibility of the oil cooler 100 freezing and cracking, and ensuring the normal use of the vehicle. By setting a second through hole 113 close to the first through hole 112, the detection component 130 can quickly acquire light information and thus quickly determine the type of cooling medium; by setting a sealing ring 140, the cooling medium is prevented from entering the detection component 130 and affecting the use of the detection component 130.

[0087] Example 2

[0088] Based on the above-described Embodiment 1, as shown in the appendix Figure 3 -Appendix Figure 5 As shown, Embodiment 2 of the present invention also provides a vehicle, including a vehicle body, a controller 200 and an oil cooler 100. The oil cooler 100 and the controller 200 are both disposed on the vehicle body. The controller 200 is electrically connected to the detection component 130 of the oil cooler 100. The controller 200 is configured to receive and process the detection information sent by the oil cooler 100.

[0089] Specifically, the controller 200 can be a device with processing capabilities in the vehicle, such as an on-board computer, an instrument display device, etc. This embodiment does not limit the carrier of the controller 200, nor is it limited to the examples described above.

[0090] Understandably, in order to convert the detection information emitted by the oil cooler 100 into the type of the corresponding coolant, the controller 200 can be configured to identify the detection information and compare the detection information to obtain the specific type of coolant.

[0091] Specifically, for example, when the controller 200 obtains transmittance as the detection information, it compares it with the corresponding transmittance of an existing cooling medium to obtain specific information about the added cooling medium, and thus obtains the specific type of the cooling medium. As another example, when the controller 200 obtains viscosity as the detection information, it compares it with the corresponding viscosity of an existing cooling medium to obtain specific information about the added cooling medium, and thus obtains the specific type of the cooling medium. The embodiments of this application do not limit the specific content of the detection information, nor are they limited to the examples described above.

[0092] As an optional implementation method, such as Figure 3 As shown, the vehicle also includes an alarm device 300, which is electrically connected to a controller 200. The controller 200 is configured to obtain the current ambient temperature and detection information of the vehicle to determine the actual freezing point of the coolant, and generate alarm information based on the actual freezing point and ambient temperature. The alarm device 300 is configured to issue an alarm action based on the alarm information.

[0093] Specifically, the controller 200 acquires the current ambient temperature of the vehicle and the detection information to determine the actual freezing point of the coolant, and compares the results to generate an alarm message; the comparison may include the following two situations:

[0094] If the freezing point is equal to or higher than the ambient temperature, the alarm actions configured in the alarm information include, but are not limited to, displaying alarm information and / or emitting an alarm sound;

[0095] If the freezing point is lower than the ambient temperature, the alarm action configured in the alarm message will be inactive.

[0096] As attached Figure 4 As shown, the steps by which the controller 200 processes the detection information include:

[0097] S10. Obtain the detection information of the cooling medium;

[0098] S20. Based on the detection information, determine the actual freezing point corresponding to the type of cooling medium;

[0099] S30. Generate alarm information based on the actual freezing point and ambient temperature.

[0100] Specifically, S30 includes: determining the relationship between the actual freezing point and the ambient temperature; if the actual freezing point is equal to or higher than the ambient temperature, generating an alarm message; if the actual freezing point is lower than the ambient temperature, no alarm message is generated.

[0101] By generating alarm information through the above steps, the use of coolants with a freezing point lower than the ambient temperature can be avoided, thus preventing the oil cooler from freezing and cracking. This effectively protects the use of the oil cooler and, consequently, the vehicle.

[0102] It is understood that displaying alarm information includes, but is not limited to, displaying images and / or text on the vehicle's computer and / or dashboard to alert the user that the coolant is unsuitable for the current environment; issuing alarm sounds includes, but is not limited to, issuing specific alarm messages such as "coolant problem" and / or alarm tone. This application does not limit the specific form of the alarm information, nor is it limited to the examples described above.

[0103] As an optional implementation method, such as Figure 5 As shown, the vehicle also includes a temperature monitor 400, which is electrically connected to the controller 200. The temperature monitor 400 is configured to acquire the current ambient temperature of the vehicle and send it to the controller 200.

[0104] Specifically, the temperature monitor 400 acquires the current ambient temperature of the vehicle and sends it to the controller 200. The controller 200 acquires the ambient temperature and the detection information sent by the detection component 130, determines the actual freezing point, and generates alarm information based on the ambient temperature.

[0105] It is understood that the temperature monitor 400 may have a temperature sensor to obtain the ambient temperature of the current vehicle, or the temperature monitor 400 may be configured to have networking and positioning functions to obtain the current vehicle location and network to obtain the ambient temperature of the current location, or other methods to obtain the current vehicle's ambient temperature. The embodiments of this application do not limit the specific form in which the temperature monitor 400 obtains the ambient temperature, nor are they limited to the above examples.

[0106] Other technical features are the same as in Embodiment 1 and can achieve the same technical effect, so they will not be described in detail here.

[0107] The vehicle provided in Embodiment 2 of the present invention includes a vehicle body, a controller 200, and an oil cooler 100. Both the oil cooler 100 and the controller 200 are mounted on the vehicle body. The controller 200 is electrically connected to a detection component 130 of the oil cooler 100. The controller 200 is configured to receive and process detection information emitted by the oil cooler 100. By setting the detection component 130 on the oil cooler 100 to detect the type of coolant added to the oil cooler 100, it is possible to avoid adding coolants with high freezing points. This prevents the coolant from solidifying due to its freezing point being higher than the ambient temperature, thus avoiding volume increase and fundamentally preventing the coolant from freezing and cracking the oil cooler 100, reducing the possibility of the oil cooler 100 freezing and cracking, and ensuring the normal use of the vehicle. An alarm device 300 is set to generate alarm information and issue an alarm action to prompt the user whether the type of coolant meets the requirements.
