Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicle-mounted devices, in particular to a vehicle-mounted charger shell, a vehicle-mounted charger and a new energy vehicle. BACKGROUND

[0002] The housings of parts in a car, such as an engine, a vehicle-mounted charger, a motor, etc., are usually processed by a die-casting aluminum process. In order to reduce the temperature inside these parts during the driving of the car, a cooling water channel is designed on the die-casting aluminum shell of the parts. The coolant of the cooling system of the car flows in the water channel of the shell, and heat is taken away through heat exchange, thereby effectively reducing the internal ring temperature and the temperature of the key electronic components, and ensuring the normal operation of the key electronic components.

[0003] The die-casting aluminum shells of different parts have great differences in shape, and the corresponding cooling water channel structures are extremely irregular. In addition, the inside of the shell needs to be hollow to ensure the flow of the coolant. At this time, the water channel of the shell needs to be processed by a die-casting core-pulling mold. On the one hand, the core-pulling hole left on the shell after core pulling needs to be plugged to ensure the sealing of the cooling water channel. On the other hand, the water channel formed by core pulling is not entirely in the path of the flow of the coolant. Due to structural limitations, there is usually an extra water channel. The coolant in this part of the water channel will form a dead water area, affecting the flow and heat exchange efficiency, and causing poor cooling performance. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0040] Some embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0041] As described in the background, the current vehicle-mounted charger shell using die-casting core-pulling mold to process the cooling water channel, on the one hand, the core-pulling hole left on the shell after core-pulling needs to be plugged to ensure the sealing of the cooling water channel, on the other hand, the water channel formed by core-pulling is not all in the path of cooling liquid flow, due to structural limitations, there is usually a redundant water channel, and the cooling liquid in this part of the water channel will form a dead water area, affecting the flow and heat exchange efficiency, resulting in poor cooling performance.

[0042] Based on this, the embodiments of the present application creatively propose a new vehicle-mounted charger shell, by setting a closure assembly in the second passage, and setting the distance from the one end of the closure assembly towards the first passage to the first passage to be less than a preset threshold, so that the cooling liquid flows along the planned ideal cooling path (i.e. the first passage) without flowing through the invalid area (i.e. the second passage), thereby ensuring the cooling performance, and ensuring the sealing of the entire life cycle of the part, further, the first passage is designed in the form of double-layer three-dimensional backflow, which basically covers the internal space of the body, and can carry away more heat, and the heat exchange efficiency is higher.

[0043] The present application will be described in detail below with specific embodiments.

[0044] Referring to Figures 1 to 7 As shown in FIG. 1, the vehicle-mounted charger housing generally comprises a body 100, a fluid passage, and a closure assembly 300. The fluid passage is formed on the body 100, and the fluid passage comprises a first passage 210 and a second passage 220 that are in communication with each other. The first passage 210 is arranged in a rotary structure in the middle of the body 100 along the height direction. One end of the second passage 220 is in communication with the first passage 210, and the other end is in communication with the external environment of the body 100. The closure assembly 300 is arranged in the second passage 220, and the distance from the one end of the closure assembly 300 towards the first passage 210 is less than a preset threshold value.

[0045] It should be noted that in the embodiments of the present application, the specific value of the preset threshold value is not limited, and can be set according to actual product requirements without deviating from the inventive concept of the present application. For example, the preset threshold value can be 0 or any non-zero value.

[0046] Further referring to Figure 7 As a preferred embodiment, in the embodiments of the present application, the closure assembly 300 comprises a first closure 310 and a sealing member 320. The sealing member 320 is sleeved on the first closure 310, and when assembled, the sealing member 320 is located between the first closure 310 and the second passage 220. It should be noted that the specific implementation of the first closure 310 and the sealing member 320 is not limited in the embodiments of the present application, and can be set according to actual product requirements without deviating from the inventive concept of the present application. For example, in some specific embodiments, the first closure 310 can be a plastic part, and the sealing member 320 can be an elastic part, such as a sealing ring with elasticity, etc., which will not be enumerated one by one here.

[0047] Further referring to Figure 7 As a preferred embodiment, in the embodiments of the present application, the closure assembly 300 further comprises a second closure 330, which is embedded in the second passage 220 at the end close to the external environment and abuts against the first closure 310, and is in interference fit with the second passage 220. When assembling, the sealing member 320 is first sleeved on the first closure 310, then the first closure 310 is inserted into the second passage 220, and finally the second closure 330 is embedded in the second passage 220 to abut against the first closure 310, so that the first closure 310 extrudes the sealing member 320, and the sealing of the sealing member 320 and the second closure 330 at two positions increases the redundancy, which can ensure the sealing performance of the part throughout its life cycle.

[0048] It should be noted that in the embodiments of the present application, the specific implementation of the second closure 330 is not limited, and can be set according to actual product requirements without departing from the inventive concept of the present application. For example, in some specific embodiments, the second closure 330 can be an elastic member, such as a bowl-shaped plug piece with elasticity, and the like, which will not be enumerated one by one here.

[0049] In some specific embodiments, the second channel 220 is a core-pulling hole (or core-pulling flow channel) left when the first channel 210 (i.e., the planned ideal cooling path) in the fluid channel is machined by using a die-casting core-pulling mold. The core rod of the die-casting core-pulling mold extends into the body 100 through the second channel 220 towards the channel opening to the external environment, and after die-casting, the hollow second channel 220 is realized. Due to the limitation of structural size and the need to reduce manufacturing cost, the closure of the channel opening of the second channel 220 to the external environment cannot be completed by friction stir welding. Therefore, the present application uses a closure assembly 30 to seal. Due to structural limitations, part of the space of the second channel 220 is not on the ideal flow path of the cooling liquid, which will cause the generation of dead water area, thereby affecting the heat dissipation efficiency of the water channel. Therefore, in the embodiments of the present application, the first closure 310, the sealing member 320 and the second closure 330 are installed in the second channel 220, realizing double sealing of the core-pulling opening to improve the service life of the part, and changing the internal space of the second channel 220, so that the cooling liquid can flow according to the planned ideal flow path.

[0050] Further referring to Figure 5 As a more preferred embodiment, in the embodiments of the present application, the second channel 220 includes a first portion 221 and a second portion 222. The first portion 221 and the second portion 222 are in communication with each other and are sequentially arranged in a direction away from the first channel 210, and in the extension direction of the second channel 220, the cross-sectional area of the second portion 222 is greater than that of the first portion 221. That is, the second channel 220 can be formed as a stepped hole, and the larger hole in the stepped hole is located on the side close to the external environment, and the smaller hole in the stepped hole is located on the side close to the first channel 210. Further, a step surface 223 is formed between the first portion 221 and the second portion 222, and the step surface 223 extends on the inner wall of the second channel 220 in a direction perpendicular to the extension direction of the second channel 220.

[0051] Further referring to Figure 7As shown, as a preferred embodiment, in the embodiment of the present application, the first closure member 310 comprises a first section 311, a second section 312 and a stepped outer circle 313 connected together. The stepped outer circle 313 is arranged between the first section 311 and the second section 312, and the sealing member 320 is sleeved on the stepped outer circle 313 and abuts against the stepped surface 223. The first section 311 is arranged in the first part 221, and the second section 312 is arranged in the second part 222. In the extension direction of the second channel 220, the cross-sectional area of the second section 312 is greater than that of the first section 311. Further, in the extension direction of the second channel 220, the cross-sectional area of the second section 312 is greater than that of the first part 221, so that when the first closure member 310 is inserted into the second channel 220, the second section 312 cannot enter the first part 221, thereby stabilizing the position of the first closure member 310 relative to the second channel 220.

[0052] During assembly, first, the sealing member 320 is sleeved on the stepped outer circle 313 of the first closure member 310, then the first closure member 310 together with the sealing member 320 is inserted into the second channel 220, and finally the second closure member 330 is embedded into the second part 222 of the second channel 220 and abuts against the second section 312 of the first closure member 310, so that the first closure member 310 extrudes the sealing member 320, thereby realizing end face sealing with the stepped surface 223 of the second channel 220. In this way, through the sealing of the sealing member 320 and the second closure member 330 at two positions, redundancy is increased, and the sealing performance of the part throughout its life cycle can be guaranteed.

[0053] In some specific embodiments, the number of the second channels 220 and the closure assemblies 300 is the same and each comprises at least two. It should be noted that in the embodiment of the present application, the specific number of the second channels 220 and the closure assemblies 300 is not limited, and can be set according to actual product requirements without departing from the inventive concept of the present application. For example, in some specific embodiments, in order to facilitate the processing of the first channel 210 in the form of a rotary structure at the middle position of the body 100 in the height direction thereof, the number of the second channels 220 and the closure assemblies 300 can each comprise two, and the two second channels 220 are arranged on the opposite sides of the body 100, for example, on the two sides in the length direction of the body 100.

[0054] Further reference is made to Figures 1 to 6As shown, the first channel 210 is arranged in the middle of the body 100 along the height direction thereof, and divides the body 100 into the first accommodating space 110 and the second accommodating space 120. The first channel 210 has a rotary structure, and includes at least a first flow passage 211, a second flow passage 212, a third flow passage 213, and a fourth flow passage 214, which are sequentially communicated to form the rotary structure. The first flow passage 211 and the second flow passage 212 are arranged close to the first accommodating space 110, the fourth flow passage 214 is arranged close to the second accommodating space 120, the first flow passage 211 and the fourth flow passage 214 extend along the length direction of the body 100, the second flow passage 212 extends along the width direction of the body 100, and the third flow passage 213 extends along the height direction of the body 100. The second flow passage 212 is further communicated with the second channel 220 at one end close to the first flow passage 211.

[0055] It should be noted that, in the embodiments of the present application, the width direction of the body 100 is the X direction in the coordinate system shown in FIG. 1, the length direction of the body 100 is the Y direction in the coordinate system shown in FIG. 1, and the height direction of the body 100 is the Z direction in the coordinate system shown in FIG. 1.

It should be noted that, in the embodiments of the present application, the specific values of the first preset angle, the second preset angle, and the third preset angle are not limited, and can be set according to actual product requirements in specific implementation.

[0058] In some specific embodiments, the first flow passage 211 has a preset side wall (not marked in the figure), and the distance between one end of the closed assembly 300 facing the first channel 210 and the preset side wall is less than a preset threshold. Preferably, the preset side wall is the side wall of the first flow passage 211 close to the side of the second channel 220.

[0059] ​​​​In some specific embodiments, the number of the first flow channels 211, the second flow channels 212, the third flow channels 213 and the fourth flow channels 214 includes at least two, so as to increase the flow path of the first channel 210 as much as possible without increasing the size of the body 100, thereby further improving the heat dissipation effect of the first channel 210. Each of the second flow channels 212 is in communication with one of the first flow channels 211 and one of the third flow channels 213, and each of the third flow channels 213 is in communication with one of the second flow channels 212 and one of the fourth flow channels 214. It can be understood that in the present application, the number of the first flow channels 211, the second flow channels 212, the third flow channels 213 and the fourth flow channels 214 can be the same or different, and preferably, the number of the first flow channels 211, the second flow channels 212, the third flow channels 213 and the fourth flow channels 214 is the same.

[0063] In some specific embodiments, the at least two fourth flow channels 214 are spaced apart in the width direction of the body 100 in the body 100.

[0064] It can be understood that through the above arrangement, the flow path and the flow area of the first channel 210 can be increased without increasing the size of the body 100, thereby further improving the heat dissipation effect.

[0065] Further referring to Figures 1 to 6 In some specific embodiments, the first channel 210 further includes an inlet 215 and an outlet 216, and the inlet 215 and the outlet 216 are arranged on the body 100 and are in communication with the first channel 210, so that the cooling liquid enters the first channel 210 through the inlet 215 or flows out of the first channel 210 through the outlet 216. The inlet 215 and the outlet 216 are arranged on the same end surface of the body 100, so as to facilitate the inlet and outlet of the first channel 210 in the body 100 which has a rotary structure.

[0066] In some specific embodiments, the shell of the vehicle charger can be prepared by a die casting process. It can be understood that due to the limitation of the die casting process, the first flow channel 211, the second flow channel 212 and the fourth flow channel 214 are in an open state when the casting blank is formed, and in order to realize the sealing of the water channel, the shell of the vehicle charger in the application further comprises a cover plate 400, wherein a plurality of recesses are formed on the body 100, and the cover plate 400 closes the recesses to form the first channel 210.

[0067] The following will be described with an example that the number of the first flow channel 211, the second flow channel 212, the third flow channel 213 and the fourth flow channel 214 is two. Further referring to Figures 1 to 6 As shown in FIG. 2, the first flow channel 211 comprises a first horizontal flow channel 211a and a second horizontal flow channel 211b, the second flow channel 212 comprises a third horizontal flow channel 212a and a fourth horizontal flow channel 212b, the third flow channel 213 comprises a first vertical flow channel 213a and a second vertical flow channel 213b, and the fourth flow channel 214 comprises a fifth horizontal flow channel 214a and a sixth horizontal flow channel 214b. The first vertical flow channel 213a and the second vertical flow channel 213b, the third horizontal flow channel 212a and the fourth horizontal flow channel 212b are arranged at the end of the first horizontal flow channel 211a and the second horizontal flow channel 211b, the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b away from the liquid inlet 215 and the liquid outlet 216.

[0068] Further referring to Figures 1 to 6 As shown in FIG. 2, one end of the first horizontal flow channel 211a is in communication with the liquid inlet 215, and one end of the second horizontal flow channel 211b is in communication with the liquid outlet 216. The end of the first horizontal flow channel 211a away from the liquid inlet 215 is in communication with one end of the third horizontal flow channel 212a and the first part 221 of one of the second channels 220, the other end of the third horizontal flow channel 212a is in communication with one end of the first vertical flow channel 213a, the other end of the first vertical flow channel 213a is in communication with one end of the fifth horizontal flow channel 214a, the other end of the fifth horizontal flow channel 214a is in communication with one end of the sixth horizontal flow channel 214b, the other end of the sixth horizontal flow channel 214b is in communication with one end of the second vertical flow channel 213b, the other end of the second vertical flow channel 213b is in communication with one end of the fourth horizontal flow channel 212b, and the other end of the fourth horizontal flow channel 212b is in communication with the end of the second horizontal flow channel 211b away from the liquid outlet 216 and the first part 221 of the other second channel 220.

[0069] When the first channel 210 is in working state, the cooling liquid enters the first channel 210 through the liquid inlet 215, flows through the first horizontal flow channel 211a and the third horizontal flow channel 212a which are arranged close to the first accommodating space 110, enters the first vertical flow channel 213a, and then enters the second accommodating space 120 which is arranged below the first accommodating space 110 through the first vertical flow channel 213a. The cooling liquid flows through the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b which are arranged close to the second accommodating space 120, enters the second vertical flow channel 213b, and then returns to the first accommodating space 110 through the second vertical flow channel 213b. The cooling liquid flows through the fourth horizontal flow channel 212b and the second horizontal flow channel 211b which are arranged close to the first accommodating space 110, and then flows out of the first channel 210 through the liquid outlet 216. From the length direction of the body 100, the cooling liquid flows through an area which covers the horizontal cross section of the shell by 180°; from the height direction of the shell, the cooling liquid flows from the flow channel close to the first accommodating space 110 to the flow channel close to the second accommodating space 120 through the first vertical flow channel 213a, and then flows from the flow channel close to the second accommodating space 120 to the flow channel close to the first accommodating space 110 through the second vertical flow channel 213b. The flowing area covers the vertical cross section of the body 100. Through such design, the contact area between the whole body 100 and the cooling liquid is large enough, the heat exchange efficiency is improved, and the temperature of the body 100 and the internal ring temperature are effectively reduced. Moreover, the first channel 210 divides the body 100 into the first accommodating space 110 and the second accommodating space 120. The double-layer three-dimensional reflux water channel design can isolate the electronic components with large heat generation from both sides of the first channel 210, avoids the problem that the temperature rises due to the close distance between the devices and the mutual interference, increases the surface area of the first channel 210 for heat dissipation of the electronic components, effectively reduces the volume and the shell weight of the vehicle charger, and improves the power density.

[0070] Further referring to Figure 6 The recesses formed on the body 100 include but are not limited to the first recess 131, the second recess 132 and the third recess 133 which are arranged in the second accommodating space 120. The first recess 131 corresponds to the first horizontal flow channel 211a, the second recess 132 corresponds to the second horizontal flow channel 211b, and the third recess 133 corresponds to the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b. Further referring to Figure 6As shown, the third recess 133 has a meandering structure, which extends from one end close to the third flow channel 213 to one end close to the liquid inlet 215, forms a recess corresponding to the fifth horizontal flow channel 214a, and then turns at one end close to the liquid inlet 215, extends from one end close to the liquid inlet 215 to one end close to the third flow channel 213, and forms a recess corresponding to the sixth horizontal flow channel 214b.

[0071] Further referring to Figure 6 As shown, the cover plate 400 at least includes a first cover plate 410, a second cover plate 420, and a third cover plate 430. Among them, the first cover plate 410 is used to seal the first recess 131 located in the second containing space 120, the second cover plate 420 is used to seal the second recess 132 located in the second containing space 120, and the third cover plate 430 is used to seal the third recess 133 located in the second containing space 120. In some specific embodiments, the first cover plate 410, the second cover plate 420, and the third cover plate 430 are combined with the body 100 through a friction stir welding process, realizing the sealing of the first horizontal flow channel 211a, the second horizontal flow channel 211b, the fifth horizontal flow channel 214a, and the sixth horizontal flow channel 214b and the structural feature of the three-dimensional meandering of the water channel.

[0072] In some specific embodiments, after the vehicle-mounted charger is assembled, the input inductor in the vehicle-mounted charger is located in the second containing space 120 corresponding to the first horizontal flow channel 211a, and the surface of the first cover plate 410 is glued to dissipate heat for the input inductor; the output inductor in the vehicle-mounted charger is located in the second containing space 120 corresponding to the second horizontal flow channel 211b, and the surface of the second cover plate 420 is glued to dissipate heat for the output inductor.

[0073] Further referring to Figures 1 to 4As shown, the body 100 is further provided with mounting slots 500 for accommodating electronic components. In order to improve the heat dissipation effect of the relevant electronic components in the mounting slots 500, the mounting slots 500 are arranged around the first channel 210 in the embodiment. In specific embodiments, the mounting slots 500 at least include a first mounting slot 510 for assembling an electrolytic capacitor, a second mounting slot 520 for assembling a main transformer and a main inductor, and a third mounting slot 530 for assembling a DCDC transformer and a DCDC inductor. The first mounting slot 510, the second mounting slot 520, and the third mounting slot 530 are all located in the first accommodating space 110 and are arranged between the first horizontal flow channel 211a and the second horizontal flow channel 211b, so as to utilize the first horizontal flow channel 211a and the second horizontal flow channel 211b to dissipate heat from the electronic components accommodated therein. The first mounting slot 510, the second mounting slot 520, and the third mounting slot 530 are sequentially arranged in the first accommodating space 110 along the length direction of the body 100, and the first mounting slot 510 is arranged at one end of the first accommodating space 110 close to the liquid inlet 215 and the liquid outlet 216. The second mounting slot 520 and the third mounting slot 530 are located at positions corresponding to the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b. In some specific embodiments, the bottom plate of the bottom of the second mounting slot 520 and the third mounting slot 530 shares the same bottom plate with the bottom plate of the bottom of the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b, so as to further dissipate heat from the electronic components accommodated in the second mounting slot 520 and the third mounting slot 530 by utilizing the fifth horizontal flow channel 214a and the sixth horizontal flow channel 214b.

[0074] In some specific embodiments, the first mounting slot 510, the second mounting slot 520, and the third mounting slot 530 are shaped according to the special shape of the electronic components to be accommodated therein, which ensures the reliability of the electronic component installation while also allowing sufficient heat dissipation of the components. At the same time, the side walls of these mounting slots can be considered as flow guide ribs and reinforcing ribs inside the body 100, which not only improve the flow speed of the liquid aluminum during die casting, but also enhance the strength of the casting itself, so that the blank of the body 100 will not deform when subjected to friction stir welding by the water channel cover plate.

[0075] Further reference is made to Figures 1 to 6As shown, the body 100 further comprises a first stepped surface 134, a second stepped surface 135, a third stepped surface 136, a fourth stepped surface 137, and a fifth stepped surface 138. The first stepped surface 134 and the second stepped surface 135 are located on the side of the second horizontal flow channel 211b facing the first accommodating space 110 and are arranged in sequence along the length direction of the body 100. The third stepped surface 136 and the fourth stepped surface 137 are located on the side of the first horizontal flow channel 211a facing the first accommodating space 110 and are arranged in sequence along the length direction of the body 100. The fifth stepped surface 138 is located on the side of the third horizontal flow channel 212a and the fourth horizontal flow channel 212b facing the first accommodating space 110. When the vehicle-mounted charger is assembled, the first stepped surface 134, the second stepped surface 135, the third stepped surface 136, and the fourth stepped surface 137 are in contact with the main IGBTs for heat dissipation of the main IGBTs; and the fifth stepped surface 138 is in contact with the power IGBT for heat dissipation of the power IGBT.

[0076] In summary, the upper side (located on the side of the first accommodating space 110) of the first horizontal flow channel 211a and the second horizontal flow channel 211b is the first stepped surface 134, the second stepped surface 135, the third stepped surface 136, and the fourth stepped surface 137 for heat dissipation of the main IGBTs, and the lower side (located on the side of the second accommodating space 120) of the first horizontal flow channel 211a and the second horizontal flow channel 211b is the first cover plate 410 and the second cover plate 420 for heat dissipation of the input inductor and the output inductor, respectively. By means of the structural layout mode that the electronic components are distributed on the upper and lower sides of the water channel, the contact area of the water channel and the components is fully utilized, the volume of the water channel and the shell is reduced, and the weight of the shell is reduced while ensuring the heat dissipation requirement of the components.
