The invention discloses a liquid cooling radiator of an engine with an electromagnetic shielding device. The liquid cooling radiator of the engine with the electromagnetic shielding device comprises a sealing shell (3), a cooling fan (4), a filter (15), a plurality of upper cooling water pipes (10), a plurality of lower cooling water pipes (14), an upper water inlet passage (7), an upper water discharge passage (8), a lower water inlet passage (11) and a lower water discharge passage (12) and is characterized in that the upper cooling water pipes (10) and upper honeycomb-shaped cooling belts (9) embedded between the upper cooling water pipes make up an upper cooling fin component (1), the lower cooling water pipes (14) and lower honeycomb-shaped cooling belts (13) embedded between the lower cooling water pipes make up a lower cooling fin component (2), the upper cooling water pipes (10) are distributed in rectangular shape and are in firm contact with the upper honeycomb-shaped cooling belts (9), the lower cooling water pipes (14) are distributed in rectangular shape and are in firm contact with the lower honeycomb-shaped cooling belts (13), and the upper cooling water pipes (10) and the lower cooling water pipes (14) are distributed on the whole ventilation surface; each of the upper honeycomb-shaped cooling belts (9) and lower honeycomb-shaped cooling belts (13) is composed of a plurality of cooling strips (16) in a hexagonal honeycomb mode, and the cooling strips are designed according to the frequency spectrum of electromagnetic noise to be shielded. The liquid cooling radiator of the engine with the electromagnetic shielding device effectively shields the radiation and conducted interference of a fan motor.
Description
technical field [0001] The invention belongs to the technical field of engine liquid cooling radiators, in particular to an engine liquid cooling radiator with an electromagnetic shielding device. Background technique [0002] The engine liquid cooling radiator uses cooling fans, cooling water channels and cooling fins to cool the engine. The motor in the cooling fan will inevitably produce electromagnetic radiation due to its own functional characteristics, or factors of input power and control lines. In various products such as generator sets that use liquid-cooled engines, electromagnetic compatibility has increasingly become an important indicator. The existing engine liquid-cooled radiator structure cannot be used as an electromagnetic shielding shell, and the heat sink itself does not have electromagnetic shielding effect, so an additional electromagnetic shielding structure must be designed. As a general discrete component, the engine liquid cooling radiator itself ...
