Description

Technical Field

[0001] The utility model relates to the field of electronic devices, and particularly to an electronic device. Background Art

[0002] An automobile is an industrial product with a complex structure. An automobile is composed of multiple devices, and each device (such as an inverter) will generate a large amount of heat during operation. To prevent the automobile from overheating and affecting its service life or even causing spontaneous combustion, cooling pipelines are usually provided inside the automobile to cool each heating device.

[0003] Taking the inverter as an example, the inverter includes a housing, and a cooling system is provided inside the housing. After the cooling medium flows through the cooling system of the inverter to absorb its heat, it needs to dissipate heat to other heating devices. For this purpose, the cooling medium outlet of the housing of the inverter needs to be connected to other heating devices so that the cooling medium can lead to each heating device.

[0004] Currently, the connection between the cooling medium outlet of the inverter and other heating devices usually needs to be realized by multiple parts. For example, the housing of the inverter is connected to a water outlet pipe, and then connected to a hose through a clamp. The hose is then connected to an oil cooler inlet adapter through a clamp. The outlet of the oil cooler is connected to an outlet adapter, and then connected to other heating devices through a cooling medium outlet pipe; thus, the large number of connecting parts leads to a high risk of leakage, and at the same time, the assembly process is complex, the procurement cost is high, and the hose has a bending radius and occupies a large space. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the connection between the current inverter and other heating devices needs to be realized by multiple parts. The utility model provides an electronic device that can reduce the number of connecting parts.

[0008] A cooling manifold, the cooling manifold is provided with a first cooling channel and a second cooling channel that are not connected to each other. The inlet of the first cooling channel is in interference fit with the cooling medium outlet, the outlet of the first cooling channel is in interference fit with the liquid inlet pipe of the heat exchanger, the inlet of the second cooling channel is in interference fit with the liquid outlet pipe of the heat exchanger, the outlet of the second cooling channel is in interference fit with one end of the cooling medium outlet pipe, and the other end of the cooling medium outlet pipe is used to connect other devices.

[0009] For ease of description, in the embodiments of the present application, an electronic device is taken as an inverter as an example for illustration. Of course, it can also be other devices, such as motors, engines, etc., and a heat exchanger is taken as an oil cooler as an example for illustration.

[0010] By adopting the above technical solution, through the setting of the cooling manifold, the cooling medium outlet is communicated with and in interference fit with the inlet of the first cooling channel. The outlet of the first cooling channel is inserted into and in interference fit with the liquid inlet pipe of the oil cooler. The inlet of the second cooling channel is inserted into and in interference fit with the liquid outlet pipe of the oil cooler. The outlet of the second cooling channel is inserted into and in interference fit with one end of the cooling medium outlet pipe. The other end of the cooling medium outlet pipe is used to connect to other devices, realizing the connection between the cooling medium outlet of the inverter and the oil cooler and other devices.

[0011] That is, the cooling medium can flow from the cooling medium outlet of the inverter to the inlet of the first cooling channel, and then to the outlet of the first cooling channel, so as to flow into the oil cooler from the liquid inlet pipe of the oil cooler. After heat exchange inside the oil cooler, it then flows from the liquid outlet pipe of the oil cooler to the inlet of the second cooling channel, and then flows into the cooling medium outlet pipe from the outlet of the second cooling channel, and flows to other devices through the cooling medium outlet pipe to cool other devices, realizing the circulation of the cooling medium between the inverter and other devices.

[0053] To make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the drawings.

[0054] Refer to Figure 1 , the inverter 100 generally includes a housing 101, and a cooling system 108 is provided inside the housing 101 (refer to Figure 2 ), and the cooling system 108 cools the electronic components (such as power modules, DC / DC conversion modules, DC-link capacitors, etc.) in the inverter 100 through a cooling medium. A cooling medium outlet and a cooling medium inlet are provided on the housing 101 (not shown in the figure), and the connection of the cooling medium outlet of the inverter 100 to other heat-generating devices usually requires multiple parts to achieve. For example, the housing 101 of the inverter 100 is connected to a water outlet pipe 102, and then connected to a hose 103 through a clamp 104. The hose 103 is then connected to an oil cooler water inlet adapter 201 through a clamp 104. The oil cooler water outlet is connected to a water outlet adapter 202, and then connected to other heat-generating devices through a cooling medium outlet pipe.

[0055] In this way, the large number of connecting parts and the cooperation between the hose 103 and the clamp 104 result in a high risk of leakage. The large number of parts makes the assembly process complex and the procurement cost high. At the same time, the hose 103 has a bending radius and occupies a large space.

[0056] Embodiments of the present application provide an electronic device, which may be an inverter, or of course other devices such as motors, engines, etc. Embodiments of the present application take the electronic device as an inverter as an example to elaborate, and take the heat exchanger as an oil cooler as an example to elaborate. By providing a cooling manifold, a plurality of parts such as hoses, clamps, and adapters are omitted, and the connection between the cooling medium outlet of the inverter and other heating devices can be achieved.

[0057] Referring to Figures 2 to 4d , the inverter includes: a housing 101, and the housing 101 is provided with a cooling medium outlet 105; a cooling manifold 300, the cooling manifold 300 is provided with a non-communicating first cooling channel 301 and a second cooling channel 302. The inlet 3010 of the first cooling channel is in communication and interference fit with the cooling medium outlet 105. The outlet 3011 of the first cooling channel is inserted and interference fit with the liquid inlet pipe 203 of the oil cooler. The inlet 3020 of the second cooling channel is inserted and interference fit with the liquid outlet pipe 204 of the oil cooler. The outlet 3021 of the second cooling channel is inserted and interference fit with one end of the cooling medium outlet pipe 107, and the other end of the cooling medium outlet pipe 107 is used to connect other devices (such as a motor).

[0058] By providing a cooling manifold, the cooling medium outlet 105 is in communication and interference fit with the inlet 3010 of the first cooling channel. The outlet 3011 of the first cooling channel is inserted and interference fit with the liquid inlet pipe 203 of the oil cooler. The inlet 3020 of the second cooling channel is inserted and interference fit with the liquid outlet pipe 204 of the oil cooler. The outlet 3021 of the second cooling channel is inserted and interference fit with one end of the cooling medium outlet pipe 107, and the other end of the cooling medium outlet pipe 107 is used to connect other devices, realizing the connection between the cooling medium outlet 105 of the inverter 100, the oil cooler 200 and other devices.

[0059] That is, the cooling medium can flow from the cooling medium outlet 105 of the inverter 100 to the inlet 3010 of the first cooling channel, and then to the outlet 3011 of the first cooling channel, so as to flow into the oil cooler 200 from the liquid inlet pipe 203 of the oil cooler. After heat exchange inside the oil cooler 200, it then flows from the liquid outlet pipe 204 of the oil cooler to the inlet 3020 of the second cooling channel, and then flows into the cooling medium outlet pipe 107 from the outlet 3021 of the second cooling channel, and flows to other devices through the cooling medium outlet pipe 107 to cool other devices, realizing the circulation of the cooling medium between the inverter 100 and other devices.

[0060] In this way, the realization of the cooling passage between the inverter 100 and other devices only requires one cooling busbar 300. The cooling medium outlet 105 is communicated with the inlet 3010 of the first cooling channel and has an interference fit, ensuring the sealing performance and omitting the clamp; the outlet 3011 of the first cooling channel is inserted into the liquid inlet pipe 203 of the oil cooler and has an interference fit, ensuring the sealing performance and omitting the hose, clamp and oil cooler water inlet adapter between the oil cooler 200 and the inverter 100; the inlet 3020 of the second cooling channel is inserted into the liquid outlet pipe 204 of the oil cooler and has an interference fit, and the outlet 3021 of the second cooling channel is inserted into one end of the cooling medium outlet pipe 107 and has an interference fit, ensuring the sealing performance and omitting the oil cooler water outlet adapter.

[0061] That is to say, compared with the prior art, the embodiments of the present application have at least the following advantages:

[0062] 1. The clamps, hoses, water inlet adapter and water outlet adapter are omitted, and the reduction in the number of parts reduces the cost;

[0063] 2. Only one cooling busbar 300 needs to be assembled, reducing the assembly difficulty;

[0064] 3. The connection of each interface no longer requires hoses and clamps, only insertion is needed, and with an interference fit, the leakage risk is reduced;

[0065] 4. The hose has a bending radius and occupies a larger space than the cooling busbar 300. Omitting the hose reduces the occupied space.

[0066] Exemplarily, referring to Figure 2 and Figure 4d , a cooling system 108 is provided inside the housing 101. The cooling system 108 cools the electronic components (such as power modules, DC / DC conversion modules, DC-link capacitors, etc.) in the inverter 100 through a cooling medium. One end of the cooling medium outlet 105 is communicated with the inlet 3010 of the first cooling channel through a first connecting pipe 109. One end of the first connecting pipe 109 is inserted into the cooling medium outlet 105 and has an interference fit, and the other end of the first connecting pipe 109 is inserted into the inlet 3010 of the first cooling channel and has an interference fit. The cooling system outlet 1081 is inserted into the other end of the cooling medium outlet 105 through a second connecting pipe 1080 and has an interference fit.

[0067] One end of the first connecting pipe 109 is inserted into the cooling medium outlet 105 and is in interference fit therewith, and the other end is inserted into the inlet 3010 of the first cooling channel and is in interference fit therewith, so as to realize the sealed connection between the cooling medium outlet 105 and the inlet 3010 of the first cooling channel. Compared with directly connecting the cooling medium outlet 105 to the oil cooler 200, there is no need for a hose connection, and thus no need for a clamp for sealing and fixing, reducing the number of parts and lowering the assembly difficulty and cost.

[0068] Exemplarily, referring to Figures 4a to 4d and combining with Figure 2 , the first cooling channel 301 includes a first channel 3012, a second channel 3013, a third channel 3014 and a fourth channel 3017 that are connected in sequence.

The liquid inlet pipe 203 of the oil cooler 200 is inserted into and in interference fit with the fourth channel 3017.

[0069] Exemplarily, the first channel 3012, the second channel 3013 and the fourth channel 3017 are all cylindrical, but are not limited thereto, and may also be cuboid, oval, etc. The shape of the third channel 3014 is similar to the shape of the cooling manifold 300 and is a cuboid shape with a notch, but is not limited thereto, and may also be cuboid, oval, etc.

[0070] Wherein, the first direction (i.e., the Figure 4a shown X direction), the second direction (i.e., the Figure 4a shown Y direction) and the third direction (i.e., the Figure 4a shown Z direction) are perpendicular to each other, but are not limited thereto, as long as the first direction, the second direction and the third direction intersect respectively.

[0071] The cooling medium can flow from the cooling medium outlet 105 to the first channel 3012, the second channel 3013, the first part 3015, the second part 3016, the fourth channel 3017 in sequence, and then flow into the oil cooler 200 from the liquid inlet pipe 203 of the oil cooler (as shown in Figure 4a andFigure 4d The schematic diagram of the flow from a to b as shown

The liquid outlet pipe 204 of the oil cooler is inserted into the fifth channel 3022 with an interference fit, and the cooling medium outlet pipe 107 is inserted into the sixth channel 3023 with an interference fit. The sixth channel 3023 extends along the second direction and is parallel to the second channel 3013.

[0073] Exemplarily, both the fifth channel 3022 and the sixth channel 3023 are cylindrical, but are not limited thereto, and may also be cuboid, elliptical, etc.

[0074] After the cooling medium exchanges heat in the oil cooler 200, it flows from the liquid outlet pipe 204 of the oil cooler to the fifth channel 3022 and the sixth channel 3023 in sequence, and then flows from the cooling medium outlet pipe 107 to other devices to cool other devices (such as Figure 4a and Figure 4d the schematic diagram of the flow from c to d as shown).

[0075] It should be noted that the specific structures and shapes of the first cooling channel 301 and the second cooling channel 302 in the embodiments of the present application are not limited, as long as the first cooling channel 301 and the second cooling channel 302 are not connected to each other, the first cooling channel 301 can connect the cooling medium outlet 105 and the liquid inlet pipe 203 of the oil cooler, and the second cooling channel 302 can connect the liquid outlet pipe 204 of the oil cooler and the cooling medium outlet pipe 107.

The weight reduction notch 303 is spaced from the fifth channel 3022 along the second direction (i.e., Figure 5b the Y direction as shown). The design of the weight reduction notch 303 can reduce the weight of the cooling manifold 300 and lower the production cost.
