Therefore, even if the adapter and the circulating liquid pipe leak water due to different thermal expansion coefficients of the joint, the adapter and the circulating liquid pipe cannot be directly contacted with electronic equipment to cause potential safety hazards. Furthermore, a drainage device and a water absorption device are arranged on the sleeve, and liquid leaked at the joint part collected in the sleeve is drained or absorbed.

The following description is made with reference to the accompanying drawings and detailed description:

The circulating liquid pipe 2 comprises a metal pipe 21 inserted into the adapter and a plastic pipe 22 which is abutted to the adapter 1, communicated with the metal pipe 21 and sleeved together to realize circulation of circulating liquid, and the metal pipe 21 and the plastic pipe 22 are fixed through a first clamp 23. Under operating condition, the circulating liquid flows through the adapter through the circulating liquid pipe 2 and enters the circulating liquid pipe again, wherein the joint of the adapter 1 and the circulating liquid pipe 2 is easy to drip the circulating liquid.

Sleeve pipe 3 is one section tubular structure in this embodiment, and the cover is established in adapter 1 and circulation liquid pipe 2's linking department to form the seal structure of a sealed adapter 1 and the linking department of circulation liquid pipe 2, in this embodiment, sleeve pipe 3's both ends are provided with second clamp 4, and two second clamps are used for the fastening fixed sleeve pipe, make and form the structure of relative sealing between two second clamps 4, spill with the circulation liquid of avoiding dripping and produce the potential safety hazard with the circuit contact. Of course, this is only one embodiment, and in other alternative embodiments, other sealing manners may be adopted, and the number of the two clips 4 is not limited thereto, as long as the sealing at the joint of the adapter 1 and the circulation pipe 2 is realized.

In other optional embodiments, also can prolong sleeve pipe 3, and is preferred, can overlap sleeve pipe 3 cover in the periphery of whole circulating liquid pipe 2, be about to circulating liquid pipe 2 and adapter 1 all wrap up through sleeve pipe 3, like this, can realize the holistic sealing of heat abstractor to realized the water and electricity separation, avoided the potential safety hazard, also can implement. Preferably, the second clamp can be arranged to further fix the product, so that the fixing reliability of the product is improved.

In this embodiment, sleeve pipe 3 is the slope setting of relative horizontal direction, and sheathed tube one end is higher than the other end promptly, and the lower department of sleeve pipe 3 is provided with the water conservancy diversion hole, owing to receive the influence of gravity, and the liquid of adapter 1 and the linking department drippage of circulating liquid pipe 2 can flow to lower one end to finally discharge through the water conservancy diversion hole.

Furthermore, the liquid leakage preventing device also comprises a guide pipe 5 and a receiving container 6, wherein the guide pipe 5 is used for discharging liquid, one end of the guide pipe 5 is connected with the guide hole, and the other end of the guide pipe is connected with the receiving container 6. When the liquid dropped from the joint of the adapter 1 and the circulating liquid pipe 2 flows to the diversion hole, the liquid is discharged to the receiving container 6 along with the diversion pipe 5 for further recovery or treatment.
