Heat dissipation device for internal combustion engine

Abstract

The invention discloses a cooling device for an internal combustion engine, which comprises a liquid cooling unit component, a liquid inlet channel and a liquid discharge channel connected to both ends of the liquid cooling unit component, the liquid cooling unit component includes a water cooling tube and a cooling fin, and the liquid inlet channel is provided with The water inlet pipe and the liquid discharge channel are provided with a water outlet pipe, and a three-dimensional radiator is arranged in the liquid discharge channel; There is an air inlet pipe, and the air outlet channel is provided with an air outlet pipe. The liquid inlet passage and the liquid discharge passage are respectively provided with a plate for the cooling water to flow back and forth, strip-shaped permeable element holes are distributed on the plate, and deflectors are provided at each water permeable element hole. The heat sink has multiple heat dissipation functions, reduces the power consumption of the fan, and reduces the manufacturing and operating costs. Compared with setting each heat sink separately, the manufacturing raw material is saved by 25%, and the volume is saved by 35%.

Description

technical field [0001] The invention relates to a cooling device for an internal combustion engine. Background technique [0002] Radiators for internal combustion engines include water radiators, oil radiators and intercoolers. The water radiators are used to dissipate heat from the cooling water of internal combustion engines. The components of the liquid cooling unit include water cooling tubes and cooling fins. The liquid inlet channel is provided with a water inlet pipe and a water supply port. The liquid discharge channel is provided with a water outlet pipe and a water discharge switch. The water radiator fan is used to cool the liquid cooling assembly. The oil radiator is used to cool the lubricating oil, including radiator, heat sink, oil inlet chamber, and oil outlet chamber. The oil inlet chamber is equipped with an oil inlet pipe, and the oil outlet chamber is equipped with an oil outlet pipe. and cooling fins. The intercooler is used to cool the supercharged a...
