Description

Technical Field

[0001] The present disclosure relates to the technical field of battery pack cooling, and in particular, to a cooling assembly and a vehicle. Background Art

[0002] The cooling plate is used to perform corresponding heating or cooling operations on the battery pack when the temperature of the battery pack decreases or increases, so as to reduce the probability of failure of the battery pack due to excessively high or low temperature and prevent thermal runaway of the battery pack. When the existing cooling plate heats the battery pack of the vehicle, a liquid film formed by the condensation of the gaseous cooling medium will adhere to the inner wall of the cooling plate, which will hinder the further phase change of the cooling medium, causing the physical phenomenon of overcooling, and reducing the heat exchange capacity of the cooling plate. When cooling the battery pack, the inner wall of the cooling plate will be filled with vapor micro-clusters formed by the evaporation of the liquid cooling medium, which will hinder the further phase change of the cooling medium, causing the physical phenomenon of overheating, and reducing the heat exchange capacity of the cooling plate. The above phenomena will affect the uniformity of the battery pack temperature, induce thermal runaway of the battery pack, and lead to safety problems. Utility Model Content

DETAILED DESCRIPTION

[0043] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0044] In the present disclosure, unless otherwise specified, directional words such as "inner" and "outer" are defined with respect to the outline of the corresponding component. The use of the terms "first", "second", etc. is intended to distinguish different components and does not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0045] According to one embodiment of the present disclosure, Figures 1 to 5 As shown, a cooling assembly is provided, which may include a cooling plate 1, a vibration generator 2 and a temperature detection element 3. Among them, a cooling chamber 10 for accommodating a cooling medium may be formed inside the cooling plate 1. The temperature detection element 3 is used to obtain the temperature information of the cooling plate 1. The vibration generator 2 is arranged on the cooling plate 1 and connected to the temperature detection element 3, and is used to vibrate the cooling medium when the temperature information exceeds the preset range. It should be noted that the temperature detection element 3 can be arranged on the cooling plate 1, or it can be contact-type detected with the cooling plate 1, and the present disclosure does not limit this. The preset range here means that a temperature interval can be pre-set, when the temperature detection element 3 can obtain temperature information of a single point or multiple points, when the preset range is a temperature interval, when the temperature information obtained is higher than the upper limit of the temperature interval or lower than the lower limit of the temperature interval, the vibration generator 2 vibrates the cooling medium. Here, the temperature information may also include temperature difference information, and the preset range may also be a temperature difference interval. The temperature detection element 3 can obtain temperature difference information between multiple points, and when the temperature difference information obtained is higher than the upper limit of the temperature difference interval or lower than the lower limit of the temperature difference interval, the vibration generator 2 vibrates the cooling medium.

[0046] Through the above technical solution, the temperature detection element 3 is connected to the cooling plate 1 to obtain the temperature information of the cooling plate 1, so as to control the vibration of the vibration generator 2. The vibration of the cooling medium in the cooling chamber 10 by the vibration generator 2 can remove the liquid film or steam micro-groups attached to the cooling plate 1, so that the cooling medium and the cooling plate 1 are fully in contact, thereby balancing the heat transfer coefficient of the cooling plate 1, thereby reducing the risk of thermal runaway caused by uneven temperature distribution of the battery pack, and meeting the thermal management requirements of the battery pack.

[0047] It should be noted that, here, the vibration generator 2 can be a motor vibrator or an ultrasonic vibrator, and the present disclosure does not limit this. The cooling component can also include a control module 4, and the control module 4 can be connected to the vibration generator 2 and the temperature detection element 3 respectively. The temperature information obtained by the temperature detection element 3 can be fed back to the control module 4, and then the vibration generator 2 is controlled to vibrate through the control module 4. Taking the ultrasonic vibrator as an example, when a condensation liquid film is attached to the cooling plate 1, the vibration generator 2 is controlled to vibrate through the control module 4, so that the inner wall of the cooling plate 1 is impacted, and the condensed liquid originally adheres to the inner wall of the cooling plate 1 by surface tension, and obtains kinetic energy due to high-frequency vibration and falls off, so that the cooling medium contacts the part of the cooling plate 1 to which the condensation liquid film is originally attached. When steam microclusters are attached to the cooling plate 1, ultrasonic waves propagate forward in a manner of alternating and continuous changes in positive and negative pressures. Under negative pressure, tiny vacuum holes can be created in the fluid cooling medium. At this time, the gas dissolved in the cooling medium will quickly enter these vacuum holes and form bubbles. Under positive pressure, the bubbles in the vacuum holes are adiabatically compressed (a compression process without heat exchange with the outside world) and finally crushed.

[0048] Here, if Figure 1 As shown, the control module 4 may include a power supply 41, a frequency conversion unit 42, a temperature acquisition unit 43 and a temperature difference warning unit 44. The power supply 41, the frequency conversion unit 42, the temperature acquisition unit 43 and the temperature difference warning unit 44 may be structures connected in series with each other, or structures connected in parallel with each other, and the present disclosure does not limit this. Among them, the vibration generator 2 may be connected to at least both the power supply 41 and the frequency conversion unit 42, and the temperature detection element 3 may be connected to at least both the temperature acquisition unit 43 and the temperature difference warning unit 44. In the case where the power supply 41, the frequency conversion unit 42, the temperature acquisition unit 43 and the temperature difference warning unit 44 may be connected in series with each other, the vibration generator 2 and the temperature detection element 3 may also be connected to the above four, and the present disclosure does not limit this.

[0049] The number of the temperature detection elements 3 can be set to be single or multiple, such as Figures 1 to 5As shown, when the number of temperature detection elements 3 is single or multiple, a temperature range can be set, and the data of the temperature detection element 3 will be fed back to the control module 4. When the temperature information obtained by the control module 4 is lower than or higher than the range, the control module 4 controls the vibration generator 2 to vibrate so that the cooling medium is in full contact with the cooling plate 1, thereby balancing the heat transfer coefficient of the cooling plate 1. In addition, in the scheme where the temperature detection element 3 is set to multiple, the multiple temperature detection elements 3 are arranged at intervals on the cooling plate 1, which can be used to obtain the temperature difference information of the cooling plate 1. The temperature detection element 3 is set at different positions of the cooling plate 1, and the control module 4 can collect the temperature information of different positions to obtain the temperature difference between different position points. The temperature difference range can be set. When the temperature difference between any two points is greater than the temperature difference range, the control module 4 controls the vibration generator 2 to vibrate so that the cooling medium is in full contact with the cooling plate 1, thereby balancing the heat transfer coefficient of the cooling plate 1.

[0050] Furthermore, if Figure 2 and Figure 3 As shown, there are multiple vibration generators 2 arranged at intervals on the cooling plate 1, and the vibration generator 2 is arranged adjacent to the temperature detection element 3. Here, the number of vibration generators 2 and temperature detection elements 3 can correspond one to one, or one vibration generator 2 can correspond to multiple temperature detection elements 3, such as as described below, when both ends of the vibration generator 2 have an impact head 243, and the vibration generator 2 is located between two protrusions of the flow channel plate 12, one vibration generator 2 can correspond to two temperature detection elements 3, and the two temperature detection elements 3 are respectively located on the side walls 122 on both sides of the vibration generator 2. In this way, when the temperature detection element 3 detects a temperature anomaly at the corresponding position, the control module 4 can control the vibration generator 2 to vibrate near the corresponding point to eliminate the liquid film or steam micro-clusters in a targeted manner, thereby more effectively balancing the heat transfer coefficient of the cooling plate 1.

[0051] In addition, the edge of the cooling chamber 10 is more prone to overcooling or overheating, and the vibration generator 2 can be set at least at the edge of the cooling chamber 10, so as to more effectively monitor the temperature of the corresponding position and make the vibration generator 2 vibrate at the corresponding point to improve the contact effect between the cooling medium and the cooling plate 1. Figure 5 As shown, in the case where the cooling chamber 10 is a plurality of protrusions, the edge of the cooling chamber 10 may be the edge of the entire cooling plate 1, such as the water inlet 61 and the water outlet 62 of the cooling plate 1, or the edge of each protrusion in the cooling plate 1. In the case where the cooling chamber 10 is a whole serpentine meandering flow channel, the edge of the cooling chamber 10 may also include the corners of the flow channel, such as the front end 63 of the branch, the end 64 of the flow channel, and the long flow channel diversion end 65. These positions are prone to overcooling or overheating, and the vibration generator 2 and the temperature detection element 3 can be arranged at these positions.

[0052] According to one embodiment of the present disclosure, Figures 1 to 3 As shown, the cooling plate 1 may include a temperature balancing plate 11 and a flow channel plate 12. The flow channel plate 12 may be buckled on the temperature balancing plate 11, and the flow channel plate 12 may be formed with a protrusion in a direction away from the temperature balancing plate 11, and a cooling chamber 10 may be formed between the protrusion and the temperature balancing plate 11. The cooling chamber 10 may be as follows: Figure 5 The uninterrupted winding flow channel shown may also be a plurality of long strip flow channels or meander flow channels arranged at intervals, and the present disclosure does not limit this.

[0053] Furthermore, if Figures 1 to 3 As shown, the vibration generator 2 and the temperature detection element 3 can both be connected to the flow channel plate 12. Compared with being connected to the temperature equalizing plate 11, the temperature of the cooling chamber 10 can be detected and the cooling chamber 10 can be vibrated more accurately and effectively, so that the cooling medium can be in contact with the cooling plate 1 more fully.

[0054] According to one embodiment of the present disclosure, Figure 2 , Figure 3 and Figure 5 The flow channel plate 12 may include a plurality of strip-shaped protrusions arranged side by side, and a top wall 121 connected between two adjacent protrusions, and the top wall 121 is fitted with the temperature equalizing plate 11. Here, the flow channel plate 12 may be integrally formed, or may be spliced ​​between the protrusions and the top wall 121, and the present disclosure does not limit this.

[0055] Furthermore, if Figure 2 , Figure 3 and Figure 5 As shown, the protrusion may include two oppositely arranged side walls 122 and a bottom wall 123. Among them, one end of the side wall 122 is respectively connected to the top wall 121, the temperature detection element 3 is arranged on the side wall 122, the vibration generator 2 is connected to the top wall 121, and is configured to be able to hit the side wall 122. The bottom wall 123 can be spaced apart from the temperature equalizing plate 11, and the bottom wall 123 and the two side walls 122 are combined to form a protrusion. The protrusion can also be semi-arc or triangular, that is, the two side walls 122 and the bottom wall 123 can jointly form an arc wall or only the two side walls 122 are arranged in a V shape, and the present disclosure does not limit this. It should be noted that the top, bottom and other directions here refer to Figure 2 The direction of the drawing does not represent the actual installation direction of the cooling plate 1. The actual installation direction of the cooling plate 1 will be set according to the relevant structure of the battery pack.

[0056] Furthermore, if Figure 2 and Figure 3 As shown, the vibration generator 2 can be located between the top wall 121 and the bottom wall 123. That is, the vibration generator 2 does not exceed the groove formed between the top wall 121 and the two adjacent side walls 122, preventing the vibration generator 2 from protruding from the cooling plate 1, thereby interfering with other components.

[0057] According to one embodiment of the present disclosure, Figures 2 to 4 As shown, the vibration generator 2 may include a substrate 21, a cylinder 22 and a movable part. Among them, the substrate 21 is connected to the cooling plate 1, the cylinder 22 is connected to the substrate 21, and the movable part can be movably arranged in the cylinder 22, for hitting the cooling plate 1 after extending out of the cylinder 22. The movable part can be connected to the control module 4. Here, the cooling plate 1, the substrate 21 and the cylinder 22 are fixedly connected, which can be adhesive or welded, and the present disclosure does not limit this. Taking the vibration generator 2 set between the two adjacent protrusions mentioned above as an example, the movable part can be controlled by the control module 4 to only reciprocate and hit the protrusion on one side without contacting the protrusion on the other side, or it can be controlled to hit the protrusions on both sides at the same time, or it can hit the protrusion on one side first and then the protrusion on the other side. The specific structure will be described in detail later.

[0058] Furthermore, if Figures 2 to 4 As shown, the movable part may include a power member 23 disposed in the cylinder 22, a movable unit 24 driven by the power member 23 and retracted in the cylinder 22, and a reset member 25. Specifically, the power member 23 may be electrically connected to the control module 4 through a wiring harness, and here, the wiring harness may also play a role in limiting the range of motion of the power member 23. The power member 23 may only vibrate in situ, and the power generated by the vibration drives the movable unit 24 to move. The power member 23 may also reciprocate along the length of the cylinder 22, thereby pushing the movable unit 24 to move, and the present disclosure does not limit this. The power member 23 is in contact with the movable unit 24, and can be used to drive the movable unit 24 to reciprocately impact the cooling plate 1. Here, in the embodiment where the vibration generator 2 is an ultrasonic vibrator, according to the size of the cylinder 22, the power member 23 may include a connecting block and a piezoelectric vibrator, the piezoelectric vibrator is connected to the control module 4 through a wiring harness, the piezoelectric vibrator is in contact with the connecting block, and the movable unit 24 is contacted through the connecting block, and the movable unit 24 is driven to move, thereby achieving the purpose of intermittently impacting the cooling plate 1. The reset member 25 can contact the movable unit 24 and the cylinder 22 respectively, and is used to provide a force to retract the movable unit 24 into the cylinder 22. In this way, when the power member 23 presses the movable unit 24 to make it hit the cooling plate 1, under the action of the reset member 25, the reset member 25 drives the movable unit 24 to press the power member 23, so that the movable unit 24 and the power member 23 are reset.

[0059] Furthermore, if Figure 4As shown, the shaft end of the cylinder 22 may be formed with a stop edge 221, and the movable unit 24 may include a base 241, a connecting section 242 and a collision head 243. The base 241 may be located inside the cylinder 22 and limited by the stop edge 221, and the base 241 contacts the power member 23 to be pushed by the power member 23. The connecting section 242 may be connected to an end of the base 241 away from the power member 23, and the connecting section 242 passes through the stop edge 221 and extends out of the cylinder 22, and the reset member 25 is connected between the connecting section 242 and the stop edge 221. The collision head 243 is connected to an end of the connecting section 242 away from the base 241 and limited by the stop edge 231. The reset member 25 may be one, or may be multiple and spaced between the connecting section 242 and the stop edge 221, and the present disclosure does not limit this. In addition, the reset member 25 may be a spring, or may be an elastic member such as rubber, and the present disclosure does not limit this. The two ends of the reset member 25 can respectively abut against the base 241 and the stop edge 221 , can be sleeved on the connecting section 242 , or can be respectively arranged on both sides of the connecting section 242 , so as to reset the impact head 243 .

[0060] In the embodiment of the present disclosure, the structure of the cylinder 22 can be a structure with one end closed and the other end open, and the power member 23 is arranged at the closed end, so that when the reset member 25 drives the movable unit 24 to reset, the movable unit 24 can also push the power member 23 until it abuts against the closed end of the cylinder 22, thereby completing a reset. At this time, the vibration of the power member 23 drives the movable unit 24 to move toward the cooling plate 1, thereby completing the next impact. In addition, if Figures 2 to 4As shown, the number of movable units 24 is two, and they are respectively arranged on both sides of the power member 23, and the power member 23 can be configured to be able to hit the two movable units 24. It should be noted that in this structure, in the initial state, the length of the vibration generator 2 (the distance between the end points of the impact heads 243 on both sides) is less than the distance between two adjacent protrusions, so that in the initial state, the impact heads 243 on both sides are spaced from the corresponding side walls 122. In this way, the power member 23 can be a power source and two connecting blocks as an example, and the two connecting blocks are respectively arranged on both sides of the power source, and are respectively in contact with the movable units 24 on both sides. When the power source moves, it can first drive the movable unit 24 on one side to hit the side wall 122, and the reset member 25 drives the movable unit 24 to reset. At this time, the movable unit 24 drives the connecting block so that the connecting block provides a force pressing against the power source. The power source can press against the other connecting block under the power of itself and the indirect power of the reset member 25. At this time, the movable unit 24 on the other side contacts the side wall 122 on the other side. The power member 23 may also be two power sources arranged in opposite directions, and two connecting blocks are respectively arranged on the other sides of the two power sources, so that the two power sources can simultaneously drive the two movable units 24 to simultaneously impact the side walls 122 on the corresponding sides, and during the process of the two reset members 25 driving the movable units 24 to reset, the two power sources can contact each other to limit each other, so as to prevent the reset members 25 from driving the movable units 24 to reset excessively, resulting in the situation that the reset members 25 cannot contact the side walls 122 when they hit next time. The power source mentioned above may be a piezoelectric vibrator, or other components such as a motor, and the present disclosure does not limit this.
