Problems solved by technology

If this heat is accumulated in the cell and the temperature of the cell rises, there is a possibility that the performance of the battery will decrease.
In addition, in the case of a battery pack, there is a concern that the progress of battery performance degradation may also vary due to temperature deviations in individual cells due to heat generation.

Embodiment 1

[0104] 1. Fabrication of frame-shaped board

[0105]

[0106] Prepare the following materials.

[0107] (1) A liquid 50g of a commercially available two-component addition-curable silicone polymer catalyst component (component C) and matrix component (component A)

[0108] (2) 40 g of a commercially available liquid B containing a crosslinking component (component B1) of a two-component addition-curable silicone polymer and a matrix component (component A)

[0109] (3) Both ends Si-H organohydrogenpolysiloxane (B2 component) 10 g

[0110] (4) 500g of alumina powder (D50: about 1-2μm)

[0111] (5) Aluminum hydroxide powder (D50: about 50μm) 550g

[0112] (6) Octyltrimethoxysilane

[0113]

[0114] (1) Knead alumina and octyltrimethoxysiloxane.

[0115] (2) Add aluminum hydroxide to (1) and knead.

[0116] (3) Add liquid A, liquid B, and component B2 to (2) and knead.

[0117] (4) After defoaming, a plate-shaped object was produced in a state sandwiched between PET fi...

Embodiment 2～4、 comparative example 1～2

[0132] Except what was shown in Table 1, it carried out similarly to Example 1.

[0133] Table 1

[0134]

[0135] As can be seen from the above examples and comparative examples, as long as the frame-shaped plate has a Shore 00 hardness of 5 or more, when the liquid heat-conducting material is pressed, lateral pressure is applied to the frame-shaped plate and no liquid leaks out. If the Shore 00 hardness exceeds 55, the rebound stress during battery assembly increases, which may cause failure due to the load applied to the battery module.

Abstract

A heat transfer sheet 10 for sealing materials, said heat transfer sheet 10 being arranged between a heat-generating electrical / electronic component and a heat dissipation case, while having a Shore 00 hardness of from 5 to 55. This heat transfer sheet 10 for sealing materials has a frame shape which internally has a space 11 that is to be filled with a liquid heat conductive composition. A heat-generating electrical / electronic component according to the present invention comprises a heat transfer sheet 11 that is bonded between the component and a case; and a space 11 among the component, the case and the heat transfer sheet 10 is filled with a liquid heat conductive composition. Consequently, the present invention provides: a heat transfer sheet for sealing materials, said heat transfer sheet being capable of preventing leakage of a liquid material even if a heat conductive liquid material is poured directly between a case and a heat-generating electrical / electronic component such as a battery module, while exhibiting high adhesion and flexibility that is good enough to avoid burdening the electrical / electronic component; and a heat-generating electrical / electronic component in which this heat transfer sheet for sealing materials is incorporated.

Description

technical field [0001] The present invention relates to a thermally conductive plate for a sealing material useful for a vehicle-mounted battery module, and a heat-generating electric / electronic component incorporating the same. Background technique [0002] In the vehicle-mounted battery module, a plurality of cells (power storage elements) are arranged and electrically connected to each other. The single cell accommodates the power generation element in the case. Heat is generated from the power generation element when the cells are charged or discharged. If this heat is accumulated in the cell and the temperature of the cell rises, there is a possibility that the performance of the battery will be reduced. In addition, in the case of a battery pack, there is a concern that the temperature of each unit cell may vary due to heat generation, and the progress of battery performance degradation may also vary. Therefore, in the prior art, it has been proposed to arrange a co...
