The chamber S can be used to contain the working fluid L to achieve the purpose of dissipating heat through the evaporation and condensation cycle of the working fluid L, the second sheet 2 and the working fluid L can transfer heat therebetween, for example, the second sheet 2 can be used as a heat dissipation sheet, so that the heat carried by the working fluid L can be transferred out of the second sheet 2, for example, to the outside for dissipation, or the second sheet 2 can be connected to other members with heat conduction effect, such as fins, heat conduction pipes or fans, to carry heat away from the second sheet 2 to achieve the purpose of dissipating heat. In addition, the chamber S may further have a capillary structure C, the capillary structure C may help the condensed working fluid L to be recollected and flow back to absorb heat of the heat generating source again, the capillary structure C may be a porous mesh structure, a micro-groove structure, or a sintered powder structure to increase the flow of the working fluid L due to capillary phenomenon, the capillary structure C may be made of a powder sintering (powder sintering) process, the powder may be copper powder or other suitable powder, which is not limited by the invention.
Referring to fig. 1 to 8, the slot surface of the first plate 1 may have at least one supporting rib 13, the supporting rib 13 may have an elongated shape and two ends, such that the supporting rib 13 extends between the annular edges 12 at two sides of the slot 11, so that two ends of the supporting rib 13 respectively face the annular edges 12, and the slot surface of the second plate 2 may also have at least one supporting rib 23, the supporting rib 23 also has an elongated shape and two ends, such that it extends between the annular edges 22 at two sides of the slot 21. For example, both ends of the supporting ribs 13,23 may be connected to the annular edges 12,22 at two opposite sides of the slots 11,21 respectively (as shown in fig. 1), or, as in the second embodiment of the present invention, both ends of the supporting ribs 13,23 may be connected to the annular edges 12,22 at two adjacent sides of the slots 11,21 respectively (as shown in fig. 5), or, as in the third embodiment of the present invention, both ends of the supporting rib 13 of the first sheet body 1 may be connected to the annular edges 12 at two adjacent sides of the slot 11 respectively, while both ends of the supporting rib 23 of the second sheet body 2 may be connected to the annular edges 22 at two opposite sides of the slot 21 respectively (as shown in fig. 7), or, as in the fourth embodiment of the present invention, at least one end of the supporting ribs 13,23 may not be connected to the annular edges 12,22 at two sides of the slots 11,21 respectively, but may have a gap P, for example, both ends of the supporting ribs 13,23 are not connected to the annular edges of the slots 11,21, The rims 12 and 22 of both sides of the groove 21, or one end of the support rib 13 and 23 is not connected to the rims 12 and 22 of the groove 11 and 21 (as shown in fig. 8), and the present invention is not limited thereto.
The support rib 13 of the first sheet 1 abuts at least one of the support ribs 23 of the second sheet 2, and preferably, the support rib 13 of the first sheet 1 intersects with the support rib 23 of the second sheet 2 to form an included angle θ, which may be 1 ° to 90 °, for example, the support rib 13 of the first sheet 1 may be orthogonal to the support rib 23 of the second sheet 2 by 90 ° (as shown in fig. 2), or the support rib 13 of the first sheet 1 may be non-orthogonal to the support rib 23 of the second sheet 2 by an acute angle smaller than 90 ° (as shown in fig. 6), which is not limited by the present invention. Thus, the non-overlapped portion of each support rib 13,23 can have a channel R with the opposite groove surface of the second blade 2 and the groove surface of the first blade 1, and the working fluid L in the cavity S can flow through the channel R and fill the cavity S, so as to transfer heat to the first blade 1 and the second blade 2. Therefore, the supporting ribs 13 and 23 can extend between the annular edges 12 and 22 at the two sides of the grooves 11 and 21 to form a supporting structure for the whole body of the first sheet body 1 and the second sheet body 2 to resist deformation, so that the strength of the temperature equalization plate structure T can be further improved, the contact area of the working fluid L is increased, and the effect of improving the heat dissipation efficiency of the temperature equalization plate structure T is achieved. In addition, the supporting rib 13 of the first blade 1 may have an enlarged portion 131, and the supporting rib 23 of the second blade 2 may have an enlarged portion 231, and the enlarged portion 131 of the first blade 1 and the enlarged portion 231 of the second blade 2 are opposite to each other and abut against each other, so that when the abutting portion of the supporting rib 13 of the first blade 1 and the supporting rib 23 of the second blade 2 is welded, the welding convenience is improved.
Referring to fig. 2, 6 and 9, the temperature equalizing plate structure T may further include a welding portion H, the welding portion H may be located at the annular edge 12 of the first plate 1 and at the annular edge 22 of the second plate 2, the welding portion H surrounds the chamber S, so that the first plate 1 and the second plate 2 may be welded together by the welding portion H, for example, by using a laser welding method, to form the chamber S, the welding portion H has a gap H1, the gap H1 is communicated with the chamber S, and the working fluid L may be injected into the chamber S from the gap H1. In detail, the annular edge 12 of the first sheet body 1 and the annular edge 22 of the second sheet body 2 can be welded incompletely, and the gap H1 left unwelded can be left, so that the annular edge 12 of the first sheet body 1 and the annular edge 22 of the second sheet body 2 can be used to form an injection port of the working fluid L, and an additional protruding port is not required to be formed for injecting the working fluid L, and the annular edge 12 of the first sheet body 1 and the annular edge 22 of the second sheet body 2 are not required to be processed, thereby saving the cost. In addition, preferably, the width of the notch H1 is less than or equal to 5mm, and preferably, the width of the notch H1 is 1mm, so that a small amount of repair welding can be performed on the notch H1 to close the notch H1, which has the effect of simplifying the step of closing the notch H1. For example, the annular edge 12 of the first plate 1 and the annular edge 22 of the second plate 2 may have a sealing portion H2, and the sealing portion H2 is located at the notch H1 so as to seal the notch H1, preferably, the sealing portion H2 is connected to the welding portion H so that the notch H1 is not communicated with the outside, for example, the sealing portion H2 may be connected to the welding portion H adjacent to the notch H1 (as shown in fig. 9), or the sealing portion H2 may be connected to the welding portion H relatively far from the notch H1 (as shown in fig. 6), and further, the sealing portion H2 may surround the welding portion H to widely block the notch H1, so as to prevent the working fluid L in the chamber S from seeping out.
Referring to fig. 1 and 2, it should be noted that the annular edge 12 of the first sheet 1 and the annular edge 22 of the second sheet 2 form an abutting portion G, and the abutting portion G is abutted against the abutting portion G through a tool at the gap H1, so as to slightly support a gap between the first sheet 1 and the second sheet 2, thereby facilitating the injection of the working fluid L into the gap H1. For example, the abutting portion G can be a notch formed by inwardly recessing the periphery of the first sheet 1 or the second sheet 2, so that when the first sheet 1 is abutted against the second sheet 2, the abutting portion G can form a step difference between the annular edges 12 and 22, so that a tool can be easily inserted between the first sheet 1 and the second sheet 2 through the abutting portion G.
Referring to fig. 5 and 6, the abutting portion G can be a flange protruding outward from the periphery of the first sheet 1 or the second sheet 2, so that when the first sheet 1 and the second sheet 2 are abutted, a step difference can still be formed between the annular edges 12 and 22 by the abutting portion G, so that a tool can be easily inserted between the first sheet 1 and the second sheet 2 from the abutting portion G. The first sheet 1 and the second sheet 2 may also have the holes and the flanges aligned with each other to form the abutting portion G (as shown in fig. 7), respectively, but the invention is not limited thereto.
In summary, the temperature-equalizing plate structure of the present invention can have the supporting ribs respectively disposed on the first sheet and the second sheet, and the supporting ribs can extend between the first sheet and the second sheet at the annular edges at two sides of the groove to form a supporting structure for the whole of the first sheet and the second sheet to resist deformation, so as to further enhance the strength of the temperature-equalizing plate structure.
