損するといった事故が屡々発生していた。26 is flat, so when replacing the heating element 3, the operation of separating the cooling structure 5 from the heating element 3 (operation of removing the fixing screw 16 and lifting the main body part 20 in the ? direction) is necessary. is particularly difficult. This is because the thermal compound 15 brings the heating element 3 and the heating element contact surface 26 into close contact with each other, making it impossible for outside air to enter the interior and creating a vacuum phenomenon. The force (in the direction of the arrow) required to separate the printed board 30 and the main body 20 depends on the number of heat generating elements 3 mounted, but it becomes quite large, and this causes damage to the structurally fragile heat generating elements 3. Accidents in which the lead 38 etc. were broken often occurred.

側の面6に通気溝1を装備した構成になっている。As described above, the conventional cooling device has a heating element contact surface [means for solving the problem].The cooling device according to the present invention has a cooling water 1 as shown in FIG.
A ventilation groove 1 is provided on the surface 6 of the heat conduction section 7 that is cooled by the heating element 3 and is in contact with the heating element 3.

ことはない。That is, a plurality of ventilation grooves are provided on the heating element contacting surface 6, one end of which is located approximately at the center of the heating element contacting surface 6, and the other end of which is open at the outer peripheral end surface 7a. Equipped with 1. This ventilation groove 1 connects the cooling structure 5 and the heating element 3.
Even when they are in close contact with each other, it is difficult for a vacuum state to be formed between the heat conductive part 7 and the heat generating element 3 due to Φ which guides outside air to the center position of the heat generating element contact surface 6. Moreover, since this ventilation groove 1 only needs to have a depth that does not obstruct the passage of air, there is no need to make the groove width wide. Therefore, the area occupied by the ventilation groove 1 is the area of the heating element contact surface 6. It may be about 1 to 2%. Therefore, the provision of the ventilation groove 1 does not reduce the amount of heat conducted from the heating element 3 to the heat conduction section 7.

い。In this embodiment, each ventilation groove 1 is formed radially, and one end is located approximately at the center of the heating element contact surface 6, or is provided through approximately the center. In addition, as long as the other end is open from the outer peripheral end surface of the heat conduction section 7, the shape of the ventilation groove l is not critical.
この通気溝1は、切削加工等によって形成しても良いし
