The invention is applicable to the technical field of engine heat dissipation, and discloses an engine heat dissipation module, an engine heat dissipation system and a control method thereof. The engine heat dissipation module, engine heat dissipation system and its control method provided by the present invention can realize separate control of the cooling of the cylinder block and the cylinder head through a motor, and use the motor to drive the ball valve to rotate to control the cooling of the cylinder body branch. The thermostat is used to control the cylinder head to realize the switching of large and small cycles. The ball valve and the thermostat are integrated in one module, which is small in size and low in cost. Under different engine operating conditions, the coolant flow to each cooling system component can be reasonably distributed. Prioritize the cooling of key areas of heat load, precisely control the amount of circulating coolant and cooling air flow, and make all parts of the engine work in the optimal temperature range to achieve rapid warm-up, thereby achieving the effect of reducing friction and emission.
Description
technical field [0001] The invention belongs to the technical field of engine heat dissipation, and in particular relates to an engine heat dissipation module, an engine heat dissipation system and a control method thereof. Background technique [0002] At present, the temperature adjustment components of most engines have two forms: thermostat and temperature control module. Among them, the thermostat is used to control the switching of the engine size and cycle, and to adjust the heat distribution state of the engine in a limited manner. The temperature control module mainly realizes the flow adjustment of multiple branches through the cooperation of the ball valve and the nozzle. The control strategy is as follows: a. Cold start, the second ball valve closes the water pump outlet flow channel, the coolant in the engine water jacket is basically close to zero flow, and the temperature rises rapidly. b. After the temperature reaches a certain set value, as soon as the bal...
