a shield that shields the control chip and the thermoelectric cooler; and
a connection line disposed on the thermoelectric cooler and configured to pass out of the shield through a through hole of the shield.
2 . The controller according to claim 1 , wherein the second connector comprises a locking mechanism, and the locking mechanism is configured to lock the first circuit board to the second connector.
3 . The controller according to claim 2 , wherein the locking mechanism comprises a screw.
4 . The controller according to claim 1 , wherein an Ethernet cable connector is disposed on the second circuit board.
5 . The controller according to claim 1 , wherein the control chip and the thermoelectric cooler are sealed in a space formed by the shield and the first circuit board.
6 . The controller according to claim 5 , further comprising a sealing ring, wherein the sealing ring is disposed between the shield and the first circuit board.
7 . The controller according to claim 5 , further comprising a glue filling portion filled in the space.
8 . The controller according to claim 1 , wherein the shield is a metal part; and
the thermoelectric cooler has a hot end, and the hot end contacts an inner surface of the shield.
9 . The controller according to claim 1 , wherein the radio frequency module and the control chip are disposed on one surface of the first circuit board.
10 . A vehicle, comprising a controller, wherein the controller comprises:
a first circuit board, wherein a first connector is disposed on the first circuit board;
a radio frequency module, disposed on the first circuit board;
a control chip, disposed on the first circuit board; and
a second circuit board, wherein
a second connector is disposed on the second circuit board, wherein the first circuit board is detachably mounted to the second circuit board through a connection between the first connector and the second connector, and
wherein the controller further comprises:
a thermoelectric cooler disposed on the first circuit board to dissipate heat for the control chip;
a shield that shields the control chip and the thermoelectric cooler; and
a connection line disposed on the thermoelectric cooler and configured to pass out of the shield through a through hole of the shield.
11 . A control method for a controller, wherein:
the controller comprises:
a first circuit board, wherein a first connector is disposed on the first circuit board;
a radio frequency module, disposed on the first circuit board;
a control chip, disposed on the first circuit board;
a second circuit board, wherein a second connector is disposed on the second circuit board, wherein the first circuit board is detachably mounted to the second circuit board through a connection between the first connector and the second connector;
a thermoelectric cooler, disposed on the first circuit board and configured to dissipate heat for the control chip;
a shield that shields the control chip and the thermoelectric cooler; and
a connection line disposed on the thermoelectric cooler and configured to pass out of the shield through a through hole of the shield; and
the control method comprises:
obtaining a temperature of the control chip; and
when the temperature is lower than a first threshold, configuring the thermoelectric cooler to stop working.
12 . The control method according to claim 11 , further comprising:
when the temperature exceeds a second threshold, configuring the thermoelectric cooler to be in a heat dissipation mode, wherein the second threshold is higher than the first threshold.
13 . The control method according to claim 11 , further comprising:
when the temperature is lower than a third threshold, configuring the thermoelectric cooler to be in a heating mode, wherein the third threshold is lower than the first threshold.
14 . The control method according to claim 11 , wherein the second connector comprises a locking mechanism, and the locking mechanism is configured to lock the first circuit board to the second connector.
15 . The control method according to claim 14 , wherein the locking mechanism comprises a screw.
