By last, in the embodiment of the utility model provides an in the theory of operation of heat dissipation module as follows: in this embodiment, different cold air inlets are formed at different positions of the housing 100, so that different air ducts are formed on the heat dissipation module, the problem that the heat dissipation capability of the heat dissipation device from the air inlet to the air outlet of the conventional heat dissipation module is uneven is greatly reduced, the heat dissipation uniformity of the whole heat dissipation module is greatly improved, and the service lives of the heat dissipation module and the power device 600 are prolonged. Specifically, the two side plates 120 of the housing 100 are provided with first air inlets 121, and are communicated with the heat dissipation channel to form a first air duct and a second air duct with the outlet end of the heat dissipation channel; a second air inlet 131 is formed in the bottom plate 130 and is communicated with the heat dissipation channel to form a third air duct with the outlet end of the heat dissipation channel; and a fourth air duct formed by the inlet end of the heat dissipation channel and the outlet end of the heat dissipation channel. Therefore, the cold air around the heat dissipation module can be introduced into the casing 100 through different air channels to take away the heat on the heat dissipation assembly 200, and because the air channels are arranged near the outlet end of the heat dissipation channel, the cold air with lower temperature can be introduced near the outlet end of the heat dissipation channel, so that the heat dissipation temperature difference between the inlet end and the outlet end of the heat dissipation channel of the heat dissipation module is reduced to a greater extent, and the problem of poor heat dissipation uniformity of the traditional heat dissipation module is solved.
In an embodiment, two side surfaces of the substrate 110 connecting the two side plates 120 are provided with a plurality of connection holes 111, and the connection holes 111 are provided. The connection position of the two side plates 120 and the substrate 110 is provided with a connection via hole corresponding to the connection hole 111. Optionally, the base plate 110 and the two side plates 120 are connected by bolts. The bolt penetrates through the connection via hole to be connected with the connection hole 111, so that the substrate 110 and the two side plates 120 are fastened.

In this embodiment, due to the nature of heat source propagation, the heat quantity propagated to the place where the power device 600 directly contacts the substrate 110 (i.e., the first heat sink portion 210) is larger, and in order to save cold energy and improve the heat dissipation efficiency of the heat dissipation apparatus, the substrate 110 is purposefully cooled, that is, the first heat sink portion 210 is provided with larger heat dissipation capacity so that more heat quantity can be carried away; a smaller heat dissipation capability is provided at the second heat sink portion 220 to save cold energy and raw materials of the heat sink assembly 200, which saves cost. Meanwhile, by performing targeted heat dissipation on the substrate 110, the temperature on the whole substrate 110 can be kept substantially consistent, so that the temperature at the bottom of the power device 600 is kept consistent, the temperature-equalizing heat dissipation effect of the power device 600 is enhanced, the heat dissipation effect of the whole power device 600 is more balanced, and the service life of the power device 600 can be greatly prolonged. Specifically, the two second heat sink portions 220 are disposed at two sides of the first heat sink portion 210, and the two heat sink portions extend toward the side plate 120 respectively, so that the heat dissipation capability of the position closer to the side plate 120 is smaller, and more raw materials can be saved.
Alternatively, the first heat sink portion 210 includes a plurality of first heat dissipation fins 211 spaced apart in the width direction of the housing 100, and the second heat sink portion 220 includes a plurality of second heat dissipation fins 221 spaced apart in the width direction of the housing 100; and the combination of (a) and (b),
the length of the first heat dissipation fin 211 is greater than that of the second heat dissipation fins 221, and the lengths of at least two of the second heat dissipation fins 221 are gradually shortened in a direction away from the first heat dissipation fin 211; and/or the presence of a gas in the gas,

The first heat dissipation fins 211 are disposed corresponding to the portions (i.e., the first heat dissipation portion 210) of the power device 600 that directly contact each other, and the second heat dissipation fins 221 are disposed corresponding to the portions (i.e., the second heat dissipation portion 220) of the power device 600 that do not directly contact each other, that is, the heat received by the plurality of first heat dissipation fins 211 is greater than the heat received by the plurality of second heat dissipation fins 221. In order to form a difference in heat dissipation capability between the first heat sink member 210 and the second heat sink member 220, a gradient distribution of heat dissipation capability is achieved by the difference in length of the heat sink fins on different heat sink members. Specifically, the length of the first heat dissipation fin 211 is greater than the length of the second heat dissipation fins 221, and optionally, the lengths of the plurality of second heat dissipation fins 221 are gradually shortened in a direction away from the first heat dissipation fin 211. Meanwhile, due to the stepped arrangement between the plurality of second cooling fins 221 and the plurality of first cooling fins 211, the wind resistance of the whole cooling channel is reduced, cold air entering the cooling channel from the plurality of air inlets can quickly reach the outlet end of the cooling channel, and the cooling efficiency is improved. It should be understood that the length direction of the heat sink is the direction in which the heat sink is parallel to the substrate 110, and the width direction of the heat sink is the direction in which the heat sink is perpendicular to the substrate 110, which is the same as the following explanation and is not repeated.
In one embodiment, one end of the first heat sink 211 is flush with one end of the second heat sink 221. The first heat sink 211 and the second heat sink 221 are flush at the outlet end of the heat dissipation channel, and the first heat sink 211 and the second heat sink 221 are arranged in a step shape at the inlet end of the heat dissipation channel.
In another embodiment, one end of the first heat sink 211 and one end of the second heat sink 221 are disposed near the outlet end of the heat dissipation channel due to process requirements.
In yet another embodiment, to provide a heat dissipation capability difference between the first heat sink piece 210 and the second heat sink piece 220, a gradient distribution of heat dissipation capability is achieved by the difference in width of the heat sink pieces on different heat sink pieces. Specifically, the width of the first heat dissipation fin 211 is greater than the width of the second heat dissipation fins 221, and optionally, the widths of the plurality of second heat dissipation fins 221 are gradually reduced in a direction away from the first heat dissipation fin 211.

In this way, since the plurality of heat conducting members 300 are disposed between the power device 600 and the substrate 110, the heat concentrated on the first heat dissipating portion 210 (i.e., the portion of the substrate 110 corresponding to the power device 600) can be first dissipated on the substrate 110 through the heat dissipating copper tubes 300, so as to achieve uniform heat dissipation at the source of heat generation, thereby improving the heat dissipation uniformity of the heat dissipation module. Specifically, the length of the heat-conducting member 300 gradually increases from the inlet end of the heat-dissipating passage to the outlet end of the heat-dissipating passage. Thus, since the higher the air-cooled temperature near the outlet end of the heat dissipation channel, the less heat it can take away from the heat dissipation assembly 200, a longer heat conduction member 300 is disposed near the outlet end of the heat dissipation channel to enhance the heat dissipation capability near the outlet end of the heat dissipation channel. Meanwhile, the number of the heat dissipation fins closer to the outlet end of the heat dissipation channel is larger, and the longer heat conduction member 300 is arranged at the outlet end close to the heat dissipation channel, so that heat transferred from the power device 600 can be more uniformly dispersed to each heat dissipation fin, and uniform-temperature heat dissipation of the heat dissipation module is realized.
