[0036] See also Figures 1 to 7Now, a dual-motor controller parallel water channel structure provided by the utility model is described. A dual-motor controller parallel water channel structure includes a main housing 100, a TM-IGBT module 200 and a GM-IGBT module 300, wherein the TM-IGBT module 200 and the GM-IGBT module 300 are respectively arranged on the upper and lower sides of the main housing 100.

[0037] A water inlet channel 110 and a drainage channel 120 are respectively arranged on the left and right sides of the main shell 100, and an upper cooling water channel 130 and a lower cooling water channel 140 are arranged in the middle of the main shell 100 from top to bottom. The water inlet channel 110 and the drainage channel 120 are connected to the upper cooling water channel 130 and the lower cooling water channel 140; the upper cooling water channel 130 is used to cool the TM-IGBT module 200 on the upper side; the lower cooling water channel 140 is used to cool the GM-IGBT module 300 on the lower side.

[0038] The utility model provides a parallel water channel structure of a dual motor controller. Compared with the prior art, the upper cooling water channel 130 and the lower cooling water channel 140 are arranged in parallel, and their positions correspond to the positions of the TM-IGBT module 200 and the GM-IGBT module 300 respectively. The cooling water enters the upper cooling water channel 130 and the lower cooling water channel 140 respectively through the water inlet channel 110, and the cooling water is finally discharged through the drainage channel 120. When the cooling water passes through the upper cooling water channel 130, the TM-IGBT module 200 can be cooled; when the cooling water passes through the lower cooling water channel 140, the GM-IGBT module 300 can be cooled.

[0039] The utility model provides a dual motor controller parallel water channel structure, the TM-IGBT module 200 and the GM-IGBT module 300 are respectively arranged on the upper and lower sides of the main housing 100 to form a parallel structure, which can greatly reduce the length of the entire controller, reduce the length of the cooling water flow, reduce the weight of the controller, and reduce the cost of using straight materials. At the same time, the use of parallel dual modules and parallel dual cooling water channel structures can avoid the problem of excessive temperature rise of cooling water far away from the inlet of the water inlet channel 110.

[0040] It is worth noting that the IGBT (Insulated Gate Bipolar Transistor) module is a modular semiconductor product that is packaged by IGBT (Insulated Gate Bipolar Transistor Chip) and FWD (Diode Chip) through a specific circuit bridge. The packaged IGBT module is directly used in inverters, UPS uninterruptible power supplies and other equipment. Among them, TM specifically refers to the drive motor, and GM specifically refers to the generator.

[0041] See also Figures 3 to 5A cooling chamber is provided in the middle of the main shell 100, and a water channel isolation wall 150 is transversely arranged in the cooling chamber. The water channel isolation wall 150 divides the cooling chamber into an upper cooling water channel 130 on the upper side and a lower cooling water channel 140 on the lower side. The water channel isolation wall 150 is located in the middle of the cooling chamber, and the front and rear sides of the water channel isolation wall 150 are respectively fixedly arranged on the front and rear inner walls of the cooling chamber. The left end of the water channel isolation wall 150 faces the water inlet channel 110, and the water inlet of the water inlet channel 110 entering the cooling chamber is divided into two water inlets respectively connected to the upper cooling water channel 130 and the lower cooling water channel 140. The right end of the water channel isolation wall 150 faces the drainage channel 120, and the drainage outlet of the drainage channel 120 out of the cooling chamber is divided into two drainage outlets respectively connected to the upper cooling water channel 130 and the lower cooling water channel 140, finally making the upper cooling water channel 130 and the lower cooling water channel 140 form two cooling water channels arranged in parallel.

[0042] In some embodiments, see Figure 3 , Figure 4 and Figure 6 The top of the upper cooling water channel 130 is provided with an upper opening, and the lower end surface of the TM-IGBT module 200 is provided with a first heat dissipation fin 210, and the number of the first heat dissipation fins 210 is multiple, and the multiple first heat dissipation fins 210 are arranged in an array. The multiple first heat dissipation fins 210 form a heat dissipation fin group. When the TM-IGBT module 200 is sealed and installed on the upper opening, the heat dissipation fin group composed of the multiple first heat dissipation fins 210 is completely inserted into the upper cooling water channel 130, and the cooling water passing through the upper cooling water channel 130 cools the multiple first heat dissipation fins 210, thereby achieving the function of cooling the TM-IGBT module 200.

[0043] The length of the first heat dissipation fin 210 is slightly smaller than the height of the upper cooling water channel 130 , so as to avoid interference between the TM-IGBT module 200 and the outer shell when being installed.

[0044] See also Figure 4 The upper end surface of the main housing 100 is provided with a first annular groove 160, which is arranged around the circumference of the upper opening. The first annular groove 160 is equidistant from the outer circumference of the upper opening, so that the shape of the first annular groove 160 is consistent with the shape of the upper opening. A first sealing ring 400 is embedded in the first annular groove 160, and the outer diameter of the longitudinal section of the first sealing ring 400 is greater than the depth of the first annular groove 160. When the TM-IGBT module 200 is installed on the upper end surface of the main housing 100, the TM-IGBT module 200 will further squeeze the first sealing ring 400, so that the first sealing ring 400 is press-fitted and sealed in the first annular groove 160, thereby achieving the effect of sealing the gap between the TM-IGBT module 200 and the main housing 100.

[0045] Among them, a plurality of main bosses are symmetrically arranged on the front and rear sides of the middle part of the main shell 100, and internal threaded holes are penetrated on the main bosses. Correspondingly, a plurality of auxiliary bosses are respectively arranged on the front and rear sides of the TM-IGBT module 200, and connecting holes are penetrated on the auxiliary bosses. Bolts are penetrated through the connecting holes and threadedly connected with the internal threaded holes, so that the TM-IGBT module 200 is installed on the upper end surface of the main shell 100, realizing a detachable connection between the two.

[0046] In some embodiments, see Figure 3 , Figure 5 and Figure 7 The bottom of the lower cooling water channel 140 is provided with a lower opening, and the upper end surface of the GM-IGBT module 300 is provided with a second heat dissipation fin 220, and the number of the second heat dissipation fins 220 is multiple, and the multiple second heat dissipation fins 220 are arranged in an array. The multiple second heat dissipation fins 220 form a heat dissipation fin group. When the GM-IGBT module 300 is sealed and installed on the lower opening, the heat dissipation fin group composed of the multiple second heat dissipation fins 220 is completely inserted into the lower cooling water channel 140, and the cooling water passing through the lower cooling water channel 140 cools the multiple second heat dissipation fins 220, thereby achieving the function of cooling the GM-IGBT module 300.

[0047] The length of the second heat dissipation fin 220 is slightly smaller than the height of the lower cooling water channel 140 , so as to avoid interference between the GM-IGBT module 300 and the outer shell when being installed.

[0048] See also Figure 5 The lower end surface of the main housing 100 is provided with a second annular groove 170, which is arranged around the circumference of the lower opening. The second annular groove 170 is equidistant from the outer circumference of the lower opening, so that the shape of the second annular groove 170 is consistent with the shape of the lower opening. A second sealing ring 500 is embedded in the second annular groove 170, and the outer diameter of the longitudinal section of the second sealing ring 500 is greater than the depth of the second annular groove 170. When the GM-IGBT module 300 is installed on the lower end surface of the main housing 100, the GM-IGBT module 300 will further squeeze the second sealing ring 500, so that the second sealing ring 500 is press-fitted and sealed in the second annular groove 170, thereby achieving the effect of sealing the gap between the GM-IGBT module 300 and the main housing 100.

[0049] Among them, a plurality of main bosses are symmetrically arranged on the front and rear sides of the middle part of the main shell 100, and internal threaded holes are penetrated on the main bosses. Correspondingly, a plurality of auxiliary bosses are respectively arranged on the front and rear sides of the GM-IGBT module 300, and connecting holes are penetrated on the auxiliary bosses. Bolts are penetrated through the connecting holes and threadedly connected with the internal threaded holes, so that the GM-IGBT module 300 is installed on the lower end surface of the main shell 100, realizing a detachable connection between the two.

[0050] See also Figure 3 The first column 180 and the second column 190 are respectively disposed on the left and right sides of the upper end surface of the main housing 100, and the first column 180 and the second column 190 are integrally formed with the main housing 100. A first channel 181 connected to the water inlet channel 110 is longitudinally opened in the first column 180, and the first channel 181 is coaxially arranged with the first column 180. A second channel 191 connected to the drainage channel 120 is longitudinally opened in the second column 190, and the second channel 191 is coaxially arranged with the second column 190. The cooling water enters the water inlet channel 110 through the first channel 181, and is finally discharged to the second channel 191 through the drainage channel 120.
