Control method for an air intake intercooler that heats or cools intake air of an engine and a control system thereof

A control method for an air intake intercooler of an engine, wherein the air intake intercooler comprises a primary thermal management unit and a secondary thermal management unit, wherein the secondary thermal management unit and the primary thermal management unit are arranged in sequence in a direction from an air inlet of the air intake intercooler to an air outlet of the air intake intercooler, and the primary thermal management unit is configured to heat and cool intake air, and the control method for an air intake intercooler comprises:

• cooling, by the secondary thermal management unit, the intake air, wherein the intake air enters the secondary thermal management unit through the air inlet of the air intake intercooler;
• acquiring real-time air intake temperature of an air inlet of the air intake intercooler, and controlling the primary thermal management unit to start a cooling mode, a heating mode, or to stop working according to the real-time air intake temperature;
• in response to the real-time air intake temperature being within a set temperature range, controlling the primary thermal management unit to stop working, and cooling the intake air through the secondary thermal management unit;
• controlling the primary thermal management unit to turn on the heating mode in response to the real-time air intake temperature being lower than a set minimum temperature limit value;
• and
• controlling the primary thermal management unit to turn on the cooling mode in response to the real-time air intake temperature being higher than a set maximum temperature limit value;
• wherein the primary thermal management unit comprises a thermocouple composed of a P-type semiconductor and an N-type semiconductor, and the secondary thermal management unit comprises a water-cooled intercooler or an air-cooled structure intercooler.
