Disclosed is a negative pressure wound healing system with wound temperature management based on a thermoelectric effect, which comprises a negative pressure wound healing device (7) having a negative pressure source (6) and a controller (8), a liquid collecting can (5) for collecting the transudate from a wound, and a wound kit for filling and sealing the wound, with the wound kit communicating with the liquid collecting can (5) through a connecting tube (4) and it also comprises a thermoelectric wound dressing kit for raising and lowering the temperature of the wound by means of a thermoelectric effect, and a wound temperature management module for managing the temperature of the wound, with the wound temperature management module connected to the controller (8) the temperature of the wound is maintained at a temperature that is optimal for the healing of the wound by way of controlling the thermoelectric wound dressing kit. The system employs a thermoelectric effect to control the temperature of the wound according to the optimal temperature for negative pressure therapy, enabling the temperature of the wound to be maintained at an optimal condition to improve the healing of the wound, so as to relieve patient pain to the greatest extent, as well as saving treatment costs.La présente invention concerne un système de cicatrisation des plaies à pression négative avec gestion de la température des plaies basée sur un effet thermoélectrique, qui comprend un dispositif de cicatrisation des plaies à pression négative (7) ayant une source de pression négative (6) et un dispositif de régulation (8), une bouteille de collecte de liquide (5) destinée à collecter le transsudat dune plaie, et un kit pour plaie destinée à remplir et fermer la plaie, le kit pour plaie communiquant avec la bouteille de collecte de liquide (5) par un tube de connexion (4). Ledit système comprend en outre un kit de pansage de plaie thermoélectrique destiné à augmenter et baisser la température de
