[0034] In this embodiment, the adjacent first connection plates 5 and second connection plates 6 are detachably connected, which can adjust the number of heat exchange units, thereby adjusting the volume, size and heat exchange amount of the heat exchange core body, so as to adapt to computer rooms or machine stations with different volumes and different heat exchange requirements.

[0035] In this embodiment, both the first connecting plate 5 and the second connecting plate 6 are made of heat-insulating materials.

[0036] In this embodiment, the multiple heat exchange units connected in sequence are the flat micro heat pipe arrays with heat dissipation fins 1. The partition plate 4 is provided with avoidance grooves for placing the flat micro heat pipe units 2, and the tightness between the partition plate 4 and the flat micro heat pipe units 2 needs to be ensured. Adjacent partition plates 4 are abutted through spacer pads 8. The spacer pads 8 have a certain compression amount to ensure the tightness between adjacent spacer pads 8. The multiple partition plates 4 divide the flat micro heat pipe arrays with heat dissipation fins 1 into two upper and lower isolated ventilation ducts.

The heat is transferred from the gas in the lower section to the gas in the upper section through the micro heat pipe arrays.

[0037] In this embodiment, both the upper ventilation duct and the lower ventilation duct can be connected to a fan.

[0038] The connecting component includes a first connecting unit and a second connecting unit;

[0039] The first connecting unit includes positioning blocks 51 respectively and fixedly arranged on both sides of the first connecting plate 5. A connecting block 52 is fixedly arranged on the side of the positioning block 51 away from the first connecting plate 5;

[0040] The second connecting unit includes a counterweight plate 74, a first connecting column 72, and an insertion block 71 fixedly connected in sequence from top to bottom.

An inclined surface is provided on the side of the connecting block 52 close to the insertion block 71.

[0041] In this embodiment, when combining the adjacent first connecting plate 5 and the second connecting plate 6, align the positioning block 51 with the positioning groove 61, bring the first connecting plate 5 and the second connecting plate 6 closer, and insert the connecting block 52 into the connecting groove 62. Due to the inclined surface of the connecting block 52, during the insertion process of the connecting block 52, the plug 71 located in the connecting groove 62 can be pushed up, compressing the spring 73 until the insertion hole 521 of the connecting block 52 moves directly below the plug 71. Under the action of the spring 73, the plug 71 enters the insertion hole 521, realizing the connection between the first connecting plate 5 and the second connecting plate 6, and ensuring the fitting between the adjacent flat micro heat pipe units 2 and the heat dissipation fins 1.

The bottom end of the second connection column 75 is fixedly connected to the top end of the counterweight plate 74. The top end of the second connection column 75 extends into the operation groove 63 and is rotatably connected to the rotating handle 76 through a rotating shaft 77. The rotation of the rotating handle 76 is used to drive the second connection column 75 to move up and down.

[0044] A driving groove is provided at the lower part of the driving side of the rotating handle 76, which is convenient for driving the rotation of the rotating handle 76.

[0045] In this embodiment, when it is necessary to remove the adjacent first connecting plate 5 and the second connecting plate 6, only need to pull the rotating handle 76, so that the rotating handle 76 rotates from the horizontal abutting state to the vertical abutting state, thereby driving the second connection column 75 to move upward, and driving the plug 71 to move upward through the counterweight plate 74 and the first connection column 72, so that the plug 71 is separated from the insertion hole 521, and the separation of the first connecting plate 5 and the second connecting plate 6 can be realized.

[0046] The flat micro heat pipe unit 2 is formed by encapsulating working medium with parallel porous aluminum plates.

[0047] Side plates 3 are fixedly connected to the outsides of the outermost flat micro heat pipe units 2, and avoidance grooves adapted to the partition plates 4 are provided in the middle of the side plates 3.

[0048] In this embodiment, the first connecting plate 5 on the leftmost and rightmost flat micro heat pipe units 2 is connected to the side plate 3 by bolts. The side plate 3 is made of heat-insulating material. The size of the spacer 8 on the partition plate 4 in contact with the avoidance groove can be adjusted accordingly.
