Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0020] A high efficiency heat dissipation power supply, reference Figure 1 , including a shell 1 which is hollow inside and opened on the upper side. A cover plate 8 for closing the shell 1 is detachably provided on the upper side. In this embodiment, a plurality of bolt slots are provided on the upper side of the shell 1, and the cover plate 8 is provided with bolt through holes whose positions and quantities match those of the bolt slots on the upper side of the shell 1. The shell 1 and the cover plate 8 are detachably connected by bolts. For those skilled in the art, there are various ways to realize the detachable connection between the shell 1 and the cover plate 8, which will not be described in detail here.

[0021] A handle 9 is detachably provided on the upper side of the cover plate 8. In this embodiment, a plurality of bolt slots are provided on the upper side of the cover plate 8, and bolts matching the positions and numbers of the bolt slots on the cover plate 8 are provided on the handle 9. The cover plate 8 and the handle 9 are detachably connected by bolts. For those skilled in the art, there are various ways to detachably connect the cover plate 8 and the handle 9, which will not be described in detail here.

[0022] The left and right sides of the housing 1 are respectively provided with a liquid inlet 3 and a liquid outlet 4. The left side of the housing 1 is provided with a plurality of power supply interfaces 2 for power supply, a control switch 12 for controlling the opening and closing of this embodiment, and a charging interface 11. Each power supply interface 2 supplies a different voltage to achieve reasonable power distribution. The charging interface 11 is used to charge this embodiment.

[0023] refer to Figure 2 and Figure 3 , a heat conducting plate 5 matching its cross section is arranged inside the shell 1. A flow channel 6 is provided inside the heat conducting plate 5. The two ends of the flow channel 6 are respectively connected to the liquid flow inlet 3 and the liquid flow outlet 4. A plurality of positioning posts 10 are arranged on the inner walls on both sides of the shell 1. Positioning notches matching the number and position of the positioning posts 10 are arranged on both sides of the heat conducting plate 5. A plurality of electrically connected battery cells 7 are arranged on both sides of the heat conducting plate 5. The battery cells 7 are cyclically chargeable and dischargeable. The battery cells 7 are electrically connected to the power interface 2, the control switch 12, and the charging interface 11.

[0024] When the battery cell 7 inside the housing 1 needs to be cooled and dissipated, a coolant is introduced into the liquid flow inlet 3 , and after the coolant absorbs the heat generated by the battery cell, it is discharged from the liquid flow outlet 4 to achieve liquid cooling.

When cooling is required, the pump sends the cooling liquid in the water-cooling cavity to the flow channel 6 for water cooling. After the cooling is completed, the pump sends the cooling liquid back to the water-cooling cavity for natural cooling. Since the water-cooling cavity is large in size and has high natural cooling efficiency, it can be recycled.
