The forging process can be, for example, a cold forging process, high-temperature heating is not needed, the crystal grains in the material can be thinned in the forging process, and bubbles are avoided, so that the second temperature guide piece 23 has better heat conduction performance compared with a cast piece made of the same material. Because the heat conduction performance of the first heat conduction member 22 and the second heat conduction member 23 is greater than that of the casting member made of the same material, the loss of cold flow or heat flow in the conduction process can be reduced, and the cold flow or heat flow generated by the temperature adjusting member 14 can be more quickly transmitted to the human body, so that the transmission time can be shortened, and the cooling or heating effect can be more quickly provided for the user.

Specifically, under the condition that materials are the same, the heat conduction performance of the stamping part and the forging part is larger than that of the casting part, and taking aluminum as an example, the heat conduction coefficient of the casting aluminum is generally 90W/m.K; the thermal conductivity of wrought and stamped aluminum is typically 230W/m.k.
