PROBLEM TO BE SOLVED: To provide a heat exchanger configured to recover heat from high-temperature liquid and heat low-temperature liquid, which can perfectly prevent mixing of high-temperature liquid and low-liquid temperature and also improve visibility on inspection and workability on replacement.SOLUTION: A heat pipe 1 is used for heat exchange means, and on an outer periphery of the heat pipe 1, a flow passage is provided so that one side of the heat pipe 1 contacts with high-temperature side fluid 20, and the other side contacts with low-temperature side fluid 21. Also, in both of the high-temperature side and low-temperature side of the flow passage, transparent resin pipes 2a, 2b are used, thereby enhancing visibility for liquid on inspection. Further, the resin pipe 2a, 2b can be detachably attached to a T-shaped joint 4a, 4b, thereby facilitating work for replacement.SELECTED DRAWING: Figure 1 【課題】高温液から熱回収し、低温液を加熱する熱交換器において、高温液と低温液の混合を完全に防止するとともに、点検における視認性、交換における作業性を改善することのできる熱交換装置を提供する。【解決手段】熱交換手段にヒートパイプ１を用い、ヒートパイプ１の一方側を高温側流体２０に、もう一方側を低温側流体２１に接するように、ヒートパイプ１外周に流路を設けた。また、この流路には、高温側、低温側ともに透明性のある樹脂管２ａ、２ｂを使用することで、点検時の液の視認性を高めた。また、上記樹脂管２ａ、２ｂをＴ字状継ぎ手４ａ、４ｂに脱着可能とし、交換時の作業を容易にした。【選択図】図１
