1. the slim heat pipe of a tool compound capillary structure is characterized in that, this slim heat pipe has:

  • One metallic cavity, it is microscler sealing shape, and has the narrow relatively sidewall of two relative flat side wall and two, is formed with a flow of vapor space in metallic cavity, this flow of vapor space has an inner surface;

    One first capillary structure layer is to be arranged on flow of vapor space inner surface along metallic cavity length and to be positioned at wherein on the flat side wall;

    One second capillary structure layer is to be arranged on the different metal structure sinter layer along metallic cavity length, and metal powder sintered capillary layer contacts with the relative pairing inner surface of another flat side wall;

    AndOne liquid is to be arranged in the flow of vapor space, can infiltrate first capillary structure layer, second capillary structure layer is carried out capillarity, and also can be heated becomes steam.
