A desiccant dehumidifier is provided in which a desiccant material is applied to a first end of a heat pipe heat exchanger. During the sorption phase, a supply air stream is exposed to the desiccant material on the first end of the heat pipe heat exchanger and a second air stream, which could be ambient atmosphere, is exposed to the second end of the heat pipe heat exchanger. The moisture from the supply air stream is transferred to the desiccant material. However, the heat pipe heat exchanger acts as a heat sink and adsorbs the heat generated by the moisture transfer and transfers it to the second end of the heat pipe heat exchanger. At the second end of the heat pipe heat exchanger, the heat is transferred to the second air stream. As a result, both the supply air stream and the desiccant material remain at a substantially constant temperature during the sorption phase. During the desorption phase, a heated air stream is exposed to the second end of the heat pipe heat exchanger, and a regeneration air stream is exposed to the first end of the heat pipe heat exchanger. The heat from the heated air stream is transferred to the heat pipe heat exchanger, and then from the heat pipe heat exchanger to the desiccant material. As a result, the surface vapor pressure of the desiccant material rises, and the moisture from the desiccant material is transferred to the regeneration air stream. In addition, in accordance with a further embodiment, after the heated air stream is cooled as it is transfers heat to the heat pipe heat exchanger, it is also used as the regeneration air stream.
