Housing and electronic device

An electronic device, comprising:

• a body;
• and
• a housing mounted in the body and configured as a battery cover of the electronic device, the housing comprising:
• a first support plate;
• a second support plate;
• a vapor chamber located between and connected to the first support plate and the second support plate, wherein the vapor chamber comprises a top wall, a bottom wall, and a side wall;
• and
• a heat dissipation channel disposed on the vapor chamber, the heat dissipation channel comprising:
• a main heat dissipation channel;
• a first auxiliary heat dissipation channel connected to the main heat dissipation channel;
• a second auxiliary heat dissipation channel connected to the main heat dissipation channel;
• a first guide channel, wherein one end of the first guide channel is connected to the main heat dissipation channel and another end of the first guide channel is connected to the first auxiliary heat dissipation channel;
• and
• a second guide channel, wherein one end of the second guide channel is connected to the main heat dissipation channel and another end of the second guide channel is connected to the second auxiliary heat dissipation channel,
• wherein the main heat dissipation channel and the auxiliary heat dissipation channels are configured such that a) when the main heat dissipation channel is a high-temperature area and the auxiliary heat dissipation channels are low-temperature areas, heat is transferred from the main heat dissipation channel to the auxiliary heat dissipation channels, and b) when the main heat dissipation channel is a low-temperature area and the auxiliary heat dissipation channels are high-temperature areas, heat is transferred from the auxiliary heat dissipation channels to the main heat dissipation channel,
• wherein a first capillary structure is disposed in the heat dissipation channel on an inner surface of the top wall of the vapor chamber, and wherein a second capillary structure is disposed in the heat dissipation channel on an inner surface of the bottom wall of the vapor chamber, and
• wherein the first support plate, the vapor chamber, and the second support plate are laminated.
