[0002] Inverter products usually use liquid-cooled heat sinks to dissipate heat from power devices. Traditional liquid-cooled heat sinks are mainly composed of a flat substrate, so liquid-cooled heat sinks can only dissipate heat from power devices. However, there are other heat-generating devices inside the product that need to be cooled, so it is necessary to add a heat sink for auxiliary heat dissipation. Therefore, multiple heat sinks need to be installed inside the product, which results in high heat dissipation costs. Utility Model Content

[0028] The utility model provides a heat sink 100 , which aims to provide a heat sink 100 capable of dissipating heat for multiple devices at the same time, so as to reduce the heat dissipation cost.

[0029] Combined with reference Figures 1 to 3In one embodiment of the radiator 100 of the utility model, the radiator 100 includes a first heat dissipation plate 10 and two second heat dissipation plates 20; the first heat dissipation plate 10 is provided with a mounting surface 11 and a back surface 12 which are arranged opposite to each other, and a first heat dissipation channel 13 is arranged in the first heat dissipation plate 10; the mounting surface 11 is used to install the first heating device; the two second heat dissipation plates 20 are arranged on two opposite sides of the first heat dissipation plate 10, and are bent toward the back surface 12 of the first heat dissipation plate 10, and the two second heat dissipation plates 20 are arranged opposite to each other to enclose a mounting cavity 20a with the first heat dissipation plate 10, and a second heat dissipation channel 21 is arranged in the second heat dissipation plate 20; the mounting cavity 20a is used to install the second heating device.

[0030] It can be understood that the radiator 100 proposed in the utility model includes a first heat sink 10 and two second heat sinks 20. The mounting surface 11 of the first heat sink 10 can be used to mount a first heating device to dissipate heat for the first heating device. The two second heat sinks 20 and the first heat sink 10 can be enclosed to form a mounting cavity 20a for mounting a second heating device to dissipate heat for the second heating device. At the same time, the first heat dissipation channel 13 and the second heat dissipation channel 21 can also take away the heat generated by other devices in the inner cavity of the converter that are not mounted on the radiator 100 through the fan to play the role of an air-to-water heat exchanger.

[0031] Therefore, the radiator 100 proposed in the present solution can not only dissipate heat for the first heat-generating device (such as a power device), but also dissipate heat for the second heat-generating device (such as an inductor, a reactor or other scattered devices), that is, it can dissipate heat for multiple devices at the same time, which is equivalent to integrating the functions of the power device radiator 100, the reactor heat dissipation housing and the air-water cooling heat exchanger into one, thereby reducing the heat dissipation cost and making full use of the heat dissipation capacity of the radiator 100, effectively reducing the failure rate caused by overheating of the converter.

[0032] In some embodiments, in order to facilitate the installation of the first heating device on the installation surface 11, a mounting hole 111 may be provided on the installation surface 11, so that the first heating device can be locked on the installation surface 11 by using a screw, a pin or other structure in cooperation with the mounting hole 111, so as to ensure the installation reliability of the first heating device. Of course, in other embodiments, the first heating device can also be fixedly installed on the installation surface 11 by means of snap fastening, bonding or the like.

[0033] In some embodiments, when installing the second heating device, the second heating device can be first placed in the installation cavity 20a, and then the thermal conductive adhesive can be poured into the installation cavity 20a to fix the second heating device in the installation cavity 20a to ensure the installation reliability of the second heating device. Of course, in other embodiments, the second heating device can also be fixed in the installation cavity 20a by means of screws, buckles, etc.

[0034] In some embodiments, the first heat dissipation plate 10 and the second heat dissipation plate 20 may be an integrally formed structure, which not only ensures the connection strength between the first heat dissipation plate 10 and the second heat dissipation plate 20 but also simplifies the preparation process.

[0035] In actual application, the first heat dissipation channel 13 and the second heat dissipation channel 21 may be interconnected or independent of each other.

[0036] Optionally, see Figure 1 In one embodiment of the radiator 100 of the utility model, the radiator 100 further includes a first side baffle 30 and a second side baffle 40 which are arranged opposite to each other. The first side baffle 30 and the second side baffle 40 are arranged on two opposite sides of the first heat dissipation plate 10. The first side baffle 30, the second side baffle 40, the first heat dissipation plate 10 and the two second heat dissipation plates 20 enclose a mounting cavity 20a.

[0037] In this way, by respectively covering the opposite sides of the first heat sink 10 with a first side baffle 30 and a second side baffle 40, the first side baffle 30, the second side baffle 40, the first heat sink 10 and the two second heat sinks 20 are surrounded by an installation cavity 20a to form a cavity with a single-sided opening, so that the second heating device can be installed in the relatively closed installation cavity 20a to increase the heat dissipation area of ​​the second heating device, thereby improving the heat dissipation effect of the second heating device.

[0038] In actual application, the first side baffle 30 and the second side baffle 40 can be fixedly installed on the opposite sides of the first heat dissipation plate 10 by means of screws, bonding, etc.

[0039] Optionally, see Figure 1 In one embodiment of the radiator 100 of the present invention, the first side baffle 30 is provided with a connecting channel (not shown), and the connecting channel connects the first heat dissipation channel 13 and the second heat dissipation channel 21 .

[0040] With such an arrangement, the first heat dissipation channel 13 can be connected to the second heat dissipation channel 21 through the connecting channel. After the coolant flows through the first heat dissipation channel 13 to take away the heat of the first heating device, it can also flow to the second heat dissipation channel 21 through the connecting channel to take away the heat of the second heating device. In this way, it is only necessary to introduce the coolant into the first heat dissipation channel 13, which can simplify the assembly cost.

[0041] Optionally, see Figure 1 In one embodiment of the radiator 100 of the present invention, the second side baffle 40 is provided with a liquid inlet channel (not shown) and a liquid outlet channel (not shown), the liquid inlet channel is connected to the first heat dissipation channel 13, and the liquid outlet channel is connected to the second heat dissipation channel 21.

[0042] With such arrangement, the coolant enters from the liquid inlet channel, flows through the first heat dissipation channel 13, the connecting channel, the second heat dissipation channel 21 in sequence, and finally flows out from the liquid outlet channel. The flow of the coolant can fully take away the heat generated by the first heating element and the second heating element during operation.

[0043] Optionally, see Figure 1 In one embodiment of the radiator 100 of the present invention, a water nozzle 50 is provided at the inlet of the liquid inlet channel and / or the outlet of the liquid outlet channel.

[0044] With such arrangement, the coolant can be smoothly led out through the water nozzle 50 arranged at the inlet of the liquid inlet channel, and the coolant after absorbing heat can be smoothly flowed out through the water nozzle 50 arranged at the liquid outlet channel.

[0045] In some embodiments, there may be a plurality of first heat dissipation channels 13, second heat dissipation channels 21, and connecting channels. Each first heat dissipation channel 13 may be connected to a second heat dissipation channel 21 via a connecting channel. Moreover, the coolant may be diverted to a plurality of first heat dissipation channels 13 via a liquid inlet channel, and the coolant in a plurality of second heat dissipation channels 21 may be converged to a liquid outlet channel.

[0046] Optionally, see Figure 2 , Figure 3 In one embodiment of the heat sink 100 of the present invention, the inner side of the connection between the first heat sink 10 and the second heat sink 20 is a contoured arc corner 22 .

[0047] With such a configuration, the design of the contoured arc angle 22 can be determined according to the shape of the second heating device, so that when installing the second heating device, the amount of thermal conductive adhesive filled in the installation cavity 20a can be reduced, thereby reducing thermal resistance, so that the first heat sink 10 and the second heat sink 20 can smoothly absorb the heat generated by the second heating device during operation.

[0048] Optionally, see Figure 2 , Figure 3 In one embodiment of the heat sink 100 of the present invention, the first heat sink 10 and the second heat sink 20 are connected via an arc segment 23 .

[0049] Such an arrangement can make the first heat sink 10 and the second heat sink 20 better transitionally connected through the arc segment 23 to ensure the connection reliability between the first heat sink 10 and the second heat sink 20 .

[0050] Optionally, see Figures 1 to 3 In one embodiment of the heat sink 100 of the present invention, a plurality of heat dissipation fins 24 are disposed on a side of each second heat dissipation plate 20 away from another second heat dissipation plate 20 .

[0051] In this way, the heat exchange area can be increased by setting the heat dissipation fins 24. The heat generated by other devices in the inner cavity of the inverter that are not installed on the radiator 100 is transferred to the heat dissipation fins 24 through the airflow forced by the fan. The heat dissipation fins 24 then transfer the heat to the first heat dissipation channel 13 and / or the second heat dissipation channel 21 inside the radiator 100. Finally, the heat is taken away by the first heat dissipation channel 13 and / or the second heat dissipation channel 21, so that the heat dissipation fins 24 play the role of an air-to-water heat exchanger.

[0052] Optionally, see Figure 3 In one embodiment of the heat sink 100 of the present invention, the second heat sink 20 is provided with a plurality of second heat dissipation channels 21 , and each second heat dissipation channel 21 is correspondingly provided with at least one heat dissipation fin 24 .

[0053] Such a configuration allows the heat after heat exchange between the heat sink fins 24 and the airflow flowing through the heat sink fins 24 to be fully transferred to the second heat sink channel 21, thereby being able to more fully take away the heat of the airflow flowing through the heat sink fins 24, thereby improving the heat dissipation effect on other components in the inner cavity of the converter that are not installed on the radiator 100.

[0054] Optionally, see Figures 1 to 3 In one embodiment of the heat sink 100 of the present invention, the heat dissipation fins 24 are extended along the extension direction of the second heat dissipation channel 21 .

[0055] Such an arrangement can make the heat absorbed by the heat dissipation fins 24 be more fully transferred to the second heat dissipation channel 21, so as to more fully remove the heat generated by other components in the inner cavity of the converter that are not installed on the heat sink 100.

[0056] The embodiment of the utility model also provides a converter, which includes a first heating device, a second heating device and the heat sink 100 as described above. The specific structure of the heat sink 100 is detailed in the above embodiment. Since the converter adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by all the technical solutions of all the above embodiments, which will not be described one by one here.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
