As shown in fig. 1 to 3, the utility model provides a box-type frequency converter heat abstractor installs in box 1 for power device 5 to installation dispels the heat in box 1.
The heat sink includes a heat sink 2 and a cooling plate 3.
The radiator 2 is located at one end of the box body 1, the fan 4 is installed on the radiator 2, an air outlet 13 is arranged on an end plate 11 of the box body 1, and the air outlet 13 is located on the outer side of the radiator 2.
The cooling plate 3 is mounted on the power device 5, and the cooling plate 3 is provided with a cooling passage 31 for providing a space for the cooling liquid to flow.
One end of the cooling channel 31 is connected to an inlet port 21 of the radiator 2 via a first pipe 61, and the other end of the cooling channel 31 is connected to an outlet port 22 of the radiator 2 via a second pipe 62.
The second pipe 62 is provided with a circulating pump 7 for providing power for the circulating flow of the cooling liquid.
The power device 5 is located inside the heat sink 2 and is spaced apart from the heat sink 2, thereby forming a first heat dissipation space 81 therebetween.
The cooling plate 3 is located on the side wall of one side of the power device 5, and a second heat dissipation space 82 is arranged between the cooling plate 3 and the side plate 12 of the corresponding side of the box body 1.
The first heat dissipation space 81 communicates with the second heat dissipation space 82.
The radiator 2 is a hollow structure in a grid shape, and the structure itself is the existing heat dissipation device, which is not the invention point of the present application.
The cooling liquid contained in the radiator 2 flows out through the liquid outlet 22 and is sent into the cooling passage 31 by the circulation pump 7 through the second pipe 62. The coolant flowing through the cooling passage 31 flows back to the radiator 2 through the first pipe 61 and the liquid inlet in this order.
The heat generated by the operation of the power device 5 is transferred to the cooling plate 3, and the cooling liquid flowing in the cooling channel 31 takes away the heat on the cooling plate 3 and sends the heat to the radiator 2, so that the power device 5 is radiated.

Circulating pump 7 is located radiator 2 below, and the heat that its during operation produced can rise to radiator 2 to outside being sent out box 1 by the air current that blows on radiator 2, the heat dissipation of accelerating circulating pump 7 that can the certain degree, improvement circulating pump life.
In order to further increase the heat dissipation speed of the heat sink 2, the side plate 12 on one side of the case 1 is provided with a heat dissipation opening 14, and the heat sink 2 is aligned with the heat dissipation opening 14.
The heat that the lateral wall of radiator 2 one side distributed out can flow outside box 1 through thermovent 14, has alleviateed the fan and has carried out the radiating pressure of initiative, avoids the fan rotational speed too high, improves fan life, guarantees that the coolant temperature that radiator 2 flowed out reduces to lower level.
In order to further increase the coverage area of the water-cooled heat dissipation, the cooling plates 3 are divided into a plurality of cooling groups.
Each cooling group comprises a plurality of cooling plates 3 connected in series, and the series connection of the cooling plates 3 is realized by connecting cooling channels 31 in series in the same cooling group.
A plurality of cooling groups are connected in parallel between the first and second pipes 61 and 62.
