[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0033] Please refer to the reference. Figures 1 to 5 This utility model embodiment provides a new energy vehicle (not shown). It can integrate the oil cooler 120 and the chip heat sink 140 into one unit, reducing the space occupied and lowering the production cost while ensuring the heat dissipation effect of the oil and the chip.

[0034] It should be noted that the new energy vehicle includes the vehicle body (not shown) and a heat dissipation and cooling device 100, a chip (not shown), and a drive unit (not shown) installed on the vehicle body. The heat dissipation and cooling device 100 is connected to both the chip and the drive unit. The heat dissipation and cooling device 100 is used to dissipate heat and cool the chip, and it is also used to cool the drive unit through oil. The heat dissipation and cooling device 100 includes an engine, transmission, or motor, and it is used to cool the engine, transmission, or motor through oil.

[0035] The heat dissipation and cooling device 100 includes a substrate 110, an oil cooler 120, and a chip heat sink 140. The oil cooler 120 is connected to the drive device, and the oil in the oil cooler 120 and the drive device can circulate between them. The chip is mounted on the chip heat sink 140. Specifically, the substrate 110 has a cooling tank 111 for supplying coolant. The oil cooler 120 is connected to the substrate 110 and covers the cooling tank 111, sealing it to prevent coolant overflow. The oil cooler 120 communicates with the cooling tank 111, allowing coolant to flow into it, thus supplying coolant to the oil cooler 120 and cooling the oil, which in turn cools the drive device. The substrate 110 has a mounting port 112 that communicates with the cooling tank 111. That is, the bottom wall of the cooling tank 111 has a mounting port 112. The chip heat sink 140 is installed in the mounting port 112. The chip heat sink 140 is used to seal the mounting port 112 to prevent the coolant in the cooling tank 111 from overflowing out through the mounting port 112. The coolant in the cooling tank 111 can exchange heat with the chip through the chip heat sink 140 to achieve the cooling function of the chip.

[0036] In this way, the coolant flowing into the cooling tank 111 can simultaneously cool the chip through the chip heat sink 140 and also enter the oil cooler 120 to cool the oil inside, thus simultaneously reducing the temperature of both the chip and the drive device, ensuring their operational performance and service life. The heat dissipation and cooling device 100 integrates the oil cooler 120 and the chip heat sink 140 into one unit, reducing space occupation, lowering production costs, and improving economic efficiency while ensuring effective heat dissipation for both the oil and the chip.

[0037] Specifically, the substrate 110 has mounting holes (not shown in the figure). The mounting holes are located outside the covering surface of the oil cooler 120. The mounting holes are used to mount the substrate 110 to the vehicle body, thereby mounting the entire heat dissipation and cooling device 100 to the vehicle body to achieve the positioning of the heat dissipation and cooling device 100.

[0038] Preferably, the substrate 110 has a liquid inlet hole 113 communicating with the cooling tank 111, that is, the bottom wall of the cooling tank 111 has a liquid inlet hole 113 for allowing coolant to enter the cooling tank 111. The oil cooler 120 has a first liquid passage hole 121 communicating with the cooling tank 111 and for allowing coolant to enter the oil cooler 120 to achieve the function of supplying coolant to the oil cooler 120. Specifically, the position of the first liquid passage hole 121 corresponds to the position of the liquid inlet hole 113 in the height direction of the heat dissipation and cooling device 100, so that part of the coolant can directly enter the oil cooler 120 through the first liquid passage hole 121.

[0039] Furthermore, the oil cooler 120 is also provided with a second liquid passage 122, which is connected to the cooling tank 111. The coolant in the cooling tank 111, after heat exchange with the chip heat sink 140, can enter the oil cooler 120 through the second liquid passage 122 and be discharged outwards. Specifically, because this part of the coolant has a high temperature (having absorbed heat from the chip), it will not participate in cooling the oil in the oil cooler 120, but will be discharged directly outwards.

[0040] It should be noted that the coolant entering the cooling tank 111 through the inlet hole 113 is divided into two parts. The first part of the coolant directly enters the oil cooler 120 through the first through hole 121 to supply coolant to the oil cooler 120 and cool the oil. The second part of the coolant flows along the cooling tank 111 toward the direction of the second through hole 122. During this process, the second part of the coolant cools the chip heat sink 140 installed in the mounting port 112 to achieve the heat dissipation function of the chip. Afterward, the second part of the coolant enters the oil cooler 120 through the second through hole 122 and is discharged directly to the outside.

[0041] In this embodiment, the oil cooler 120 is generally rectangular in shape. The second liquid passage 122 is diagonally arranged with the first liquid passage 121, that is, the liquid inlet 113 and the second liquid passage 122 are diagonally arranged. This allows the second portion of coolant entering the cooling tank 111 through the liquid inlet 113 to flow a longer distance within the cooling tank 111 before reaching the second liquid passage 122 and entering the oil cooler 120. This prolongs the flow time of the second portion of coolant within the cooling tank 111, ensuring the cooling effect of the second portion of coolant on the chip heat sink 140. However, this is not the only embodiment. In other embodiments, the second liquid passage 122 and the first liquid passage 121 can also be arranged opposite each other on the same side. The specific layout of the second liquid passage 122 and the first liquid passage 121 is not limited.

[0042] Preferably, the substrate 110 has an oil inlet hole 114, which is spaced apart from and independently arranged from the cooling tank 111. The oil cooler 120 has a first oil passage hole 123, which is connected to the oil inlet hole 114. The oil inlet hole 114 and the first oil passage hole 123 are used to supply oil in sequence. The high-temperature oil in the drive device can enter the oil cooler 120 through the oil inlet hole 114 and the first oil passage hole 123, so as to use the first part of the coolant to cool down the high-temperature oil.

[0043] Correspondingly, the substrate 110 is provided with an oil outlet hole 115, which is spaced apart from and independently arranged from the cooling tank 111. The oil cooler 120 is provided with a second oil passage hole 124, which is connected to the oil outlet hole 115. The second oil passage hole 124 and the oil outlet hole 115 are used to supply oil to be discharged in sequence. The oil in the oil cooler 120 can be discharged outward through the second oil passage hole 124 and the oil outlet hole 115, so as to transport the low-temperature oil after cooling to the drive device, thereby realizing the cooling and temperature reduction of the drive device.

[0044] In this embodiment, the oil cooler 120 is rectangular in shape. The second oil passage 124 and the first oil passage 123 are diagonally arranged, that is, the oil inlet 114 and the oil outlet 115 are diagonally arranged. The line connecting the second oil passage 124 and the first oil passage 123 intersects the line connecting the second liquid passage 122 and the first liquid passage 121. That is, the first liquid passage 121, the first oil passage 123, the second liquid passage 122 and the second oil passage 124 are distributed in a rectangular array and are respectively arranged at the four corners of the oil cooler 120 to facilitate the flow direction control of oil and coolant.

[0045] Preferably, there are multiple chip heat sinks 140 and mounting ports 112 (two or more), with multiple mounting ports 112 spaced apart. Each chip heat sink 140 is installed in one mounting port 112, and each chip heat sink 140 is used to install a group of chips. Multiple chip heat sinks 140 work together to simultaneously achieve the heat dissipation and cooling function of multiple groups of chips, thereby improving heat dissipation efficiency.

[0046] Furthermore, a partition wall 116 protrudes from the bottom wall of the cooling tank 111 towards the oil cooler 120. The partition wall 116 is located between two adjacent mounting ports 112 and serves to create multiple liquid flow channels 117 within the cooling tank 111. Each liquid flow channel 117 is connected to one mounting port 112, meaning that the coolant in each liquid flow channel 117 is used to dissipate heat from one chip heat sink 140. Specifically, the partition wall 116 separates the multiple liquid flow channels 117, causing turbulence in the coolant within the cooling tank 111 during flow, thereby improving the heat dissipation effect on the chip heat sink 140.

[0047] In this embodiment, there are two chip heat sinks 140 and two mounting ports 112. A partition wall 116 is disposed between the two mounting ports 112 to create two liquid flow channels 117 within the cooling tank 111. Each liquid flow channel 117 is connected to one mounting port 112. However, this is not the only embodiment. In other embodiments, the number of chip heat sinks 140, mounting ports 112, and liquid flow channels 117 can be three or four. The specific number of chip heat sinks 140, mounting ports 112, and liquid flow channels 117 is not limited.

[0048] The oil cooler 120 includes an overlapping top plate 125, a bottom plate 126, and multiple heat exchange plates 127. The multiple heat exchange plates 127 are connected sequentially, with the top plate 125 connected to the top of the multiple heat exchange plates 127 and the bottom plate 126 connected to the bottom of the multiple heat exchange plates 127. The bottom plate 126 covers the cooling tank 111 and is connected to the base plate 110. Specifically, a first liquid passage 121, a first oil passage 123, a second liquid passage 122, and a second oil passage 124 are all formed on the bottom plate 126 to facilitate the flow of oil and coolant.

[0049] Furthermore, the plurality of heat exchange plates 127 includes a plurality of first heat exchange plates 1271 and a plurality of second heat exchange plates 1272. The plurality of first heat exchange plates 1271 and the plurality of second heat exchange plates 1272 are arranged alternately in sequence. A first heat exchange plate 1271 forms a first heat exchange channel 128 with an adjacent second heat exchange plate 1272, and a second heat exchange channel 129 forms with an adjacent second heat exchange plate 1272. The plurality of first heat exchange channels 128 are sequentially connected, and the plurality of second heat exchange channels 129 are sequentially connected. Specifically, the first heat exchange channel 128 is used for coolant flow, and the second heat exchange channel 129 is used for oil flow. The coolant and oil exchange heat through the first heat exchange plates 1271 or the second heat exchange plates 1272 to achieve the function of cooling the oil.

[0050] In this embodiment, fins 130 are provided in the first heat exchange channel 128. The fins 130 are used to increase the contact area with the coolant and improve the heat exchange efficiency. However, it is not limited to this. In other embodiments, fins 130 can be provided in the second heat exchange channel 129 to increase the contact area with the oil, which can also improve the heat exchange efficiency.

[0051] The heat dissipation and cooling device 100 provided in this embodiment of the utility model has a cooling groove 111 formed on a substrate 110. An oil cooler 120 is connected to the substrate 110 and covers the outside of the cooling groove 111, communicating with the cooling groove 111. The substrate 110 has a mounting port 112 communicating with the cooling groove 111, and a chip heat sink 140 is installed in the mounting port 112. The cooling groove 111 is used to supply coolant to cool the chip heat sink 140 and to supply coolant to the oil cooler 120. Compared with the prior art, the heat dissipation and cooling device 100 provided in this utility model, by using the oil cooler 120 connected to the substrate 110 and the chip heat sink 140 installed in the mounting port 112, can achieve the integration of the oil cooler 120 and the chip heat sink 140, reducing the space occupied and lowering production costs while ensuring the heat dissipation effect of the oil and the chip. This results in high heat dissipation efficiency, good heat dissipation effect, and good economic benefits for new energy vehicles.

[0052] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
