Description

  The present invention relates to a cooling table for a heat generating device such as a notebook computer.

  A personal computer generates heat during operation, such as a CPU that performs a calculation function, a hard disk of a storage device, and a power supply portion, and it is necessary to cool this heat generation to a usable temperature range.

  In addition to the heat generated in the power supply unit, this heat generation is caused by the fact that the CPU has high performance, the recording density of the hard disk increases, and the rotation speed increases, the heat generation amount increases accordingly.

  Therefore, various proposals have been made as cooling means for absorbing heat of a notebook personal computer as a heat generating device (for example, Patent Document 1, Patent Document 2, and Patent Document 3).

WO2005 / 066740 JP 2007-65851 A Registered Utility Model No. 3116467

  By the way, the cooling pad of Patent Document 1 is such that the nearest metal heat transfer plate is brought into contact with the bottom surface of a heat generating device such as a laptop computer, and the heat is transferred from the heat transfer plate to the lower heat absorption gel body. It is.

  According to such a method, the heat transfer plate is distorted by the influence of the heat of the device, and is deformed in accordance with the distortion, so that the entire lower surface of the heat transfer plate does not contact the endothermic gel body.

  For this reason, the endothermic efficiency cannot be exhibited 100%, and there is a problem in suppressing the temperature rise of the device.

  In particular, since the whole is packaged in a resin bag, the heat transmitted to the heat transfer plate cannot be dissipated, that is, the absorbed heat is hidden in the bag.

  Further, according to the ventilation gap forming sheet of Patent Document 2, a vent is provided on the surface on the heat generating device side and the side surface of the sheet, and a ventilation path connected to the vent is formed on the inner side of the sheet. It is not mandatory. For this reason, there existed a problem which cannot promote endothermic efficiency effectively.

  Furthermore, according to the cooling stand for notebook computers of Patent Document 3, the cooling material for the cooling stand is provided with a composite composition in which paralite is supported on paralite, and the cooling material is filled in a bag made of an aluminum laminate film. There is no means for effectively dissipating the heat of the heat generating device that has absorbed heat into the coolant.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cooling table in which heat absorbed by the cooling table of the heat generating device is radiated extremely well.

  In order to solve the above-described problems, the present invention forms a flat cooling mat with a bag and an endothermic gel enclosed in the bag, and the upper surface of the cooling mat and heat generation are formed on the periphery of the cooling mat. The cooling table is provided with an edge frame made of a heat radiation material that does not hinder contact with the lower surface of the device, and a bottom plate made of a heat radiation material that contacts the lower surface of the cooling mat on the lower surface of the edge frame.

  Moreover, the structure which provided the leg for the space | gap formation with respect to a mounting surface in the lower surface of at least one side of the said edge frame or a baseplate may be employ | adopted.

  As described above, according to the cooling table of the heat generating device of the present invention, the heat of the heat generating device is absorbed by the heat absorbing gel constituting the cooling mat by placing the heat generating device such as a notebook computer on the cooling table on the desk. As a result, the operation of the heat generating device is stabilized, and the frame of the heat dissipation material is provided on the periphery of the cooling mat, and the bottom plate of the heat dissipation material is provided on the lower surface of the cooling mat. Thus, there is a unique effect of efficiently maintaining the cooling function of the cooling mat.

  In particular, when an edge frame is provided on the periphery of the cooling mat, the contact between the upper surface of the cooling mat and the lower surface of the heat generating device is not hindered. Can be improved.

  In addition, since legs are provided on at least one lower surface of the edge frame or bottom plate, there is a gap between the placed cooling table (edge frame or bottom plate) and the desk, and this problem is effective as a heat dissipation path. Can dissipate heat.

It is a perspective view which shows the cooling stand of this invention. It is the perspective view which looked at the cooling stand from the bottom. It is a vertical expansion front view same as the above. It is a vertical expansion front view of a cooling mat.

  In the embodiment of the present invention, as shown in FIGS. 1, 2, and 3, A is a cooling mat configured in a flat plate shape with a bag body 1 and an endothermic gel 2 sealed in the bag body 1.

  The bag body 1 is rich in flexibility and uses a material in which the entire upper surface of the bag body 1 is in contact with the entire lower surface of the heat generating device X such as a laptop computer. For example, as shown in FIG. A three-layer structure of a polyethylene film 11 excellent in heat-welding property, an aluminum sheet 12 for heat absorption in the middle, and a polyester film 13 that is flexible on the outside (easy to be in close contact with the lower surface of the heating device X). Although it was configured by heat-sealing the entire overlapping edge of the upper and lower two sheets, it is not limited and may be other sheets that achieve the above object.

  The endothermic gel 2 includes, for example, water, isobutylene, a sodium salt cross-linked product of maleic anhydride copolymer, cross-linked sodium polyacrylate, or a mixture of sodium sulfate aqueous solution, silica fine powder, ethanol, and the like.

  Further, an edge frame B made of a heat dissipating material is provided at the periphery of the cooling mat A so as not to obstruct the contact between the upper surface of the cooling mat A and the lower surface of the heat generating device X.

  As the edge frame B, the edge-shaped heat sealing portion of the bag body 1 is inward from the opening of the inner side surface of the edge member 4 so that the groove-shaped edge member 4 whose inner side surface is open is located on the four sides. Is inserted so that the upper surface of the bag body 1 protrudes upward with respect to the upper surface of the edge member 4 to ensure good contact of the entire lower surface of the heat generating device X with the upper surface of the bag body 1.

  Further, on the lower side of the bag body 1, there is provided a bottom plate 5 made of a heat dissipation material with the upper surface superimposed on the lower surface of the bag body 1. The bottom plate 5 has each edge portion fitted and held inside the lower edge of the edge member 4.

  For example, aluminum is used as the edge material 4 and the bottom plate 5 of the heat dissipation material, but other materials for the same purpose may be used.

  Further, at least one lower surface of the edge frame B or the bottom plate 5 is provided with a leg 6 for forming a gap with respect to the mounting surface (desk) Y.

  In the illustrated case, the leg 6 is provided at the lower surface dotted position of the edge frame B. However, the leg 6 is not limited and can be provided only on the lower surface of the bottom plate 5 or both the edge frame B and the bottom plate 5. Use an adhesive.

  If comprised as mentioned above, the heat | fever of the heat generating apparatus X, such as a notebook personal computer, will be absorbed and cooled by the cooling mat A, and the heat absorbed by the cooling mat A will be effectively thermally radiated by the edge frame B and the bottom plate 5, In addition, since the gap is formed between the desk Y and the edge frame B and the bottom plate 5 by the legs 6, heat dissipation is promoted.

  For this reason, unlike the conventional cooling method, the temperature rise of the cooling mat A is remarkably reduced, and there is an advantage that the heat generating device X is not adversely affected.

  A cooling stand for heat-generating equipment such as a notebook computer that effectively dissipates heat absorbed by the cooling mat.
