[0027] like Figure 1 and Figure 3 As shown, the lower plate portion 1 is used to contact a heat source (not shown), and can be covered with the upper plate portion 2 to form a chamber A between the lower plate portion 1 and the upper plate portion 2; specifically, a concave shape can be formed on the lower plate portion 1 to cover the upper plate portion 2, so that the concave shape is covered by the upper plate portion 2 and sealed with the lower plate portion 1, thereby forming the chamber A. In addition, a lower capillary structure 10 is provided on the lower plate portion 1, and the lower capillary structure 10 is located in the chamber A, and can be composed of a woven mesh, powder sintering, or grooves formed on the surface of the lower plate portion 1.

The sandwiched capillary layer 22 can be composed of a woven mesh, and has a connecting edge 22a protruding outside the peripheral edge of the inner plate 21 formed at a position relative to the peripheral edge of the inner plate 21; in other words, the sandwiched capillary layer 22 is larger in size than the inner plate 21, so that it can have the connecting edge 22a protruding outside the peripheral edge of the inner plate 21, and when the upper plate portion 2 and the lower plate portion 1 are covered, the sandwiched capillary layer 22 is in contact with the lower capillary structure 10 with its connecting edge 22a. In the embodiment of the present invention, the lower capillary structure 10 is further provided with a lateral portion 10a covering the inner wall of the periphery of the chamber A. The lateral portion 10a cooperates with the inner wall of the periphery of the chamber A and extends toward the outer plate 20 of the upper plate portion 2 to contact the connecting edge 22a of the sandwiched capillary layer 22.

[0029] In addition, if Figure 4 As shown, in the second embodiment of the utility model, an upper capillary structure 23 can be further provided on the inner plate 21 of the upper plate portion 2.

In addition, the inner plate 21 of the upper plate 2 is further provided with at least one through hole 21a corresponding to the connecting hole 22b, so that the chamber A formed by the lower plate 1 and the upper plate 2 can be connected with the inside of the tube 3; at this time, the inner plate 21 may not have or be provided with structures such as holes.

[0032] Furthermore, if Figure 7 As shown, in the fourth embodiment of the utility model, the tube portion 3 can also form a tube end 3c outside the flange 30a of the above-mentioned tubular capillary structure 30, and the tube end 3c can be a part of the tube portion 3, and after the flange 30a is exposed by methods such as annular cutting, the smaller connecting hole 22b can extend into and contact the flange 30a, and the tube end 3c is connected to the inner plate 21 in a ladder-like or vertical direction, so that the tube portion 3 can be fixed on the connecting hole 20a of the upper plate portion 2.

[0033] Therefore, by means of the capillary sandwich type temperature equalization device of the utility model, the upper plate portion 2 of the temperature equalization plate is provided with the outer plate 20 and the inner plate 21, so that the sandwiched capillary layer 22 is sandwiched between the outer plate 20 and the inner plate 21, thereby ensuring the reflux of the liquid working fluid. At the same time, the utility model can further add a tube portion 3 such as a heat pipe to the upper plate portion 2 to form a temperature equalization device commonly known as a "3D temperature equalization plate", which is more conducive to the reflux of the tube capillary structure 30 in the tube portion 3 and the sandwiched capillary layer 22 of the upper plate portion 2.
