The disclosure discloses a portable ice or heat pack, which includes main body, a first fixing member, and a second fixing member. The main body has an upper surface and a lower surface, and an enclosure chamber is defined by the main body for receiving a thermal medium. The first fixing member is disposed on the upper surface, and a first channel is formed between the first fixing member and the upper surface. The second fixing member is disposed on the lower surface, and a second channel is formed between the second fixing member and the upper surface. An extension direction of the second channel is different from an extension direction of the first channel.本創作提供一冷熱敷袋,其包括:一本體、一第一固定元件、及一第二固定元件。該本體具有一上表面及一相反該上表面之下表面,其中一密閉腔室係由該本體所定義,該密閉腔室係配置用以儲存一導熱介質。該第一固定元件,設置於該本體之該上表面,其中一第一通道形成於該第一固定元件與該本體之該上表面之間。該第二固定元件,設置於該本體之該下表面,其中一第二通道形成於該第二固定元件與該本體之該下表面之間,該第二通道之延伸方向係不同於該第一通道之延伸方向。1‧‧‧冷熱敷袋10‧‧‧本體11‧‧‧第一側邊12‧‧‧第二側邊13‧‧‧第三側邊14‧‧‧第四側邊15‧‧‧上表面18‧‧‧密閉腔室20‧‧‧第一固定元件21‧‧‧第一中央部22‧‧‧第一端部23‧‧‧第一通道40‧‧‧標語W1‧‧‧第一間距W2‧‧‧第二間距
