A pair of semiconductor refrigeration healthcare underpants comprising an underpants main body (1). A liquid layer (2) is provided on the underpants main body (1). The healthcare underpants also comprises an external mobile refrigeration source box (4). The interior of the mobile refrigeration source box (4) is divided into a heat-dissipation area and an enclosed refrigeration area by a semiconductor refrigeration plate (7) and a connecting plate connected to two ends of the semiconductor refrigeration plate (7). A heat exchange water-cooling head (5) is arranged on the semiconductor refrigeration plate (7) at the refrigeration area. The liquid layer (2) is connected to the heat exchange water-cooling head (5) via a liquid inlet tube (3) and is connected to a water pump (9) and the heat exchange water-cooling head (5) via a liquid outlet tube (31). A heat sink (8) is arranged on the semiconductor refrigeration plate (7) at the heat-dissipating area. A ventilation hole (10) is provided on a sidewall of the mobile refrigeration source box (4) corresponding to the heat-dissipation area. The semiconductor refrigeration plate (7) and the water pump (9) are provided with a power supply connection cable. By carrying the mobile refrigeration source box (4), when exercising or in an overheating weather, electricity is supplied to allow the refrigeration source box (4) to start working, thereby allowing a liquid in the liquid layer (2) on the underpants main body (1) to exchange heat with the refrigeration plate (7) in the refrigeration source box (4), thus allowing for reduced temperature of the private part, keeping cool, and facilitating bodily health.Linvention concerne un caleçon médical à réfrigération à semi-conducteur comportant un corps principal de caleçon (1).
