Figure 2 It is Figure 1 the exploded schematic diagram of the thermal test tool. Figure 3 It is Figure 1 the cross - sectional schematic diagram of the thermal test tool.

[0051] The thermal test tool 10 of this embodiment is, for example, used in an immersion cooling system (not shown) and is used to be immersed in a coolant (not shown). The thermal test tool 10 includes a base 11, a backplane 12, a heating component 13, a first seal 14, and a second seal 15. The backplane 12 is disposed on the base 11 and together with the base 11 defines a first receiving groove R1, a second receiving groove R2, and a third receiving groove R3.

[0052] Specifically, please refer to Figure 4 . Figure 4 It is Figure 1Schematic plan view of the base of the thermal test tool. The base 11 has an inner surface 111 facing the backplane 12, and a recess 1111 is formed on the inner surface 111. The first accommodation groove R1, the second accommodation groove R2, and the third accommodation groove R3 are located in the recess 1111 and are recessed inward. The base 11 has a channel 112. The channel 112 communicates with the first accommodation groove R1. The second accommodation groove R2 is located on the periphery of the first accommodation groove R1 and is spaced apart from the first accommodation groove R1 by a distance D1. The third accommodation groove R3 is located on one side of the first accommodation groove R1 adjacent to the second accommodation groove R2 and is located in the channel 112, and the third accommodation groove R3 is spaced apart from the first accommodation groove R1 by a distance D2. Among them, the distance D1 between the first accommodation groove R1 and the second accommodation groove R2 is, for example, smaller than the distance D2 between the first accommodation groove R1 and the third accommodation groove R3.

[0053] The heating component 13 includes a heating sheet 131. Part of the heating sheet 131 is located in the first accommodation groove R1, and another part of the heating sheet 131 is located in the channel 112. The first seal 14 is, for example, coated on the second accommodation groove R2 and is located on the periphery of at least part of the heating sheet 131. The second seal 15 is, for example, coated on the third accommodation groove R3. The first seal 14 and the second seal 15 are formed of a polymer such as fluorocarbon polymer, acrylic resin, epoxy resin, polyethylene, polypropylene, polycarbonate, or a combination thereof.

[0054] Specifically, the so-called coating means that reactants are pre-filled into the accommodation grooves R2 and R3, for example, by means of a squeegee, a steel plate, or dispensing. After the heating component 13 is coated and assembled, the reactants react in the accommodation grooves R2 and R3, and then the seals 14 and 15 made of polymer are formed.

[0055] In this embodiment, by providing the first seal 14 in the second accommodation groove R2 and the second seal 15 in the third accommodation groove R3, the sealing effect between the base 11 and the backplane 12 can be improved, and when the thermal test tool 10 is immersed in the coolant, the coolant of the immersion cooling system can be prevented from seeping into the heating sheet 131 located in the first accommodation groove R1, thereby reducing the operating efficiency and service life of the heating sheet 131.

[0056] In this embodiment, the thermal test tool 10 may further include a second cable 16. The second cable 16 is connected to the heating sheet 131 at the channel 112 and is electrically connected to an external power supply device (not shown) to transmit power to the heating sheet 131 through the second cable 16.

[0058] In addition, through the fastening of these fasteners 17, the back plate 12 can be closely attached to the base 11. In this way, the back plate 12 and the base 11 can apply pressure to the first seal 14 and the second seal 15, so that the first seal 14 and the second seal 15 are respectively closely attached to the second receiving groove R2 and the third receiving groove R3, thereby further improving the sealing effect between the base 11 and the back plate 12.

[0059] In this embodiment, the thermal test tool 10 includes a first seal 14 and a second seal 15, and the back plate 12 and the base 11 jointly enclose a second receiving groove R2 and a third receiving groove R3, so that the first seal 14 and the second seal 15 are respectively disposed in the second receiving groove R2 and the third receiving groove R3, but not limited thereto.
