[0032] The condenser 11 has a housing 20, an inner housing 30, and a plurality of fins 40. The housing 20 is connected to the base 101. The inner housing 30 is disposed in the housing 20. A plurality of the fins 40 are stacked in the inner housing 30. The heat pipes 102 pass through the fins 40. A first channel 41, a second channel 42, and a plurality of condensation chambers 43 spaced apart in the vertical direction are formed between the plurality of fins 40. Each condensation chamber 43 communicates with the first channel 41 and the second channel 42. A first interface 21 and a second interface 22 are provided on the housing 20.

By providing notches 313 on the periphery of the bottom cover 31 and providing an annular cavity 25 between the inner shell 30 and the outer shell 20, the coolant can flow into the first inner cavity 311 from the notches 313 in four directions simultaneously, and the flow rate of the coolant per unit time is larger, and the heat dissipation efficiency is high.

The first avoidance hole 314 and the third avoidance hole 44 are both corresponding to the first heat pipes 104 one by one. By setting the outer wall of the first heat pipe 104 to be attached to the inner wall of the third avoidance hole 44, the heat on the first heat pipe 104 can be quickly transferred to the fin 40, and then the coolant takes away the heat on the fin 40, and the heat dissipation efficiency is high.
[0038] The second channel 42 is disposed in the middle between the fins 40, and a plurality of the first channels 41 are annularly distributed outside the first channel 41; by arranging the second channel 42 in the middle between the fins 40 and a plurality of the first channels 41 being annularly distributed outside the first channel 41, the coolant converges from all directions to the second channel 42 and flows out from the second channel 42, making the flow of the coolant smoother, and further enabling the coolant to fully and quickly take away heat.
[0039] The number of the second channels 42 is single, and the diameter of the second channel 42 > the diameter of the first channel 41.

A second inner cavity 321 is formed between the upper surface of the top cover 32 and the inner top wall of the outer shell 20. A fourth avoidance hole 322 is provided on the top cover 32.

By providing a gap 324 between the circumferential inner wall of the groove 323 and the circumferential outer wall of the first heat pipe 104, and the gap 324 allows the coolant to flow so that the coolant contacts the upper end of the heat pipe 102, more heat on the first heat pipe 104 can be taken away more fully. At the same time, it can also prevent the coolant from not flowing after absorbing heat, avoiding the phenomenon of internal heat accumulation.
[0044] The lower surface of the top cover 32 abuts against the upper surface of the inner shell 30. An annular convex edge 325 is provided on the circumferential side of the top cover 32. The upper surface of the annular convex edge 325 abuts against the inner top wall of the outer shell 20.
