1. A heat dissipation module, comprising:
a heat dissipation film, wherein the heat dissipation film comprises grid glue, foam and a metal film which are arranged in a stacked manner;
a first release film arranged on one side, facing away from the foam, of the grid glue;
a second release film arranged on one side, facing away from the foam, of the metal film, wherein the heat dissipation film and the second release film are provided with a first windowing area and a second windowing area which penetrate through a thickness direction, and an exhaust passage is arranged between the second windowing area and an edge of the heat dissipation film;
a first protective film arranged on one side, facing away from the heat dissipation film, of the second release film, and covering the first windowing area; and
a second protective film arranged on one side, facing away from the heat dissipation film, of the second release film, and covering the second windowing area and the exhaust passage, wherein the first protective film and the second protective film are independently arranged.
