Concrete, the diameter of red copper fiber is 100 μ m～200 μ m.As required, the diameter of red copper fiber can be adjusted in this scope.The diameter of preferred red copper fiber is 100 μ m～150 μ m or 120 μ m～160 μ m.The diameter of employed red copper fiber can be a single value, also can be the mixture of the red copper fiber of several kinds of diameters, and the red copper fiber of preferred single diameter is more.
Concrete, the length of red copper fiber is 2mm～10mm.As required, the length of red copper fiber can be adjusted in this scope.The length of employed red copper fiber can be single value, also can be the mixture of the red copper fiber of several kinds of length, and the red copper fiber of preferred single length is more.
Concrete, the length of red copper fiber is 2mm～5mm.The diameter of preferred red copper fiber is 2mm～5mm.Because therefore difficult annular space of inserting red copper pipe and plug formation of the red copper fiber that length is long, when making heat pipe, preferentially selects the short fiber of 2mm for use.
Concrete, the tooth depth of tooth is 0.1mm～0.25mm, the facewidth is 0.1mm～0.20mm.As required, the tooth depth of tooth and the facewidth can be adjusted in this scope respectively.
Concrete, the quantity of the tooth of little groove 1 is 30～70.As required, the quantity of tooth can be selected in this scope respectively.
Concrete, tooth is that cross sectional shape is one or several the combination in rectangle, trapezoidal, semicircle and the lance tooth.
The number of teeth of above-mentioned little groove 1, tooth depth and the facewidth are variable, can form different MCAs; The length of red copper fiber is optional, also can be as required carry out the rules orientation sintering or random sintering forms to the red copper fiber.
The specific embodiment of the micro heat pipe of the utility model, as shown in Figure 3, the wick that includes body and be arranged at inboard wall of tube body, wherein, wick is the groove composite fibre wick in the foregoing description 1.
The manufacturing approach of the micro heat pipe of present embodiment may further comprise the steps:
The specific embodiment of the soaking plate of the utility model; Like Fig. 4 and shown in Figure 5, include first lid and second lid, the edge of first lid and second lid is tightly connected; Be provided with cavity between first lid and second lid; First lid and second lid are provided with wick towards a side of cavity, and wherein, wick is the groove composite fibre wick in the foregoing description 1.
The manufacturing approach of the soaking plate internal channel composite fibre wick of present embodiment may further comprise the steps:
Step 4, sintering are accomplished, and treat that stove is chilled to room temperature, lay down mould, promptly in the cavity of first housing of soaking plate and second housing, obtain groove composite fibre wick.
Should be noted that at last; Above embodiment is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain, although with reference to preferred embodiment the utility model has been done explanation at length, those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of the utility model, and not break away from the essence and the scope of the utility model technical scheme.
