| titleOfInvention | Exhaust gas recirculation cooling system using refrigerant vaporization heat |
| abstract | The present invention provides a water cooling method or a compressor using an EGR cooler in an exhaust gas recirculation apparatus which reduces the combustion temperature in a cylinder by recirculating the exhaust gas into an intake cylinder to reduce the generation of nitrogen oxides (NOx). The present invention relates to an exhaust gas recirculation system cooling system using a refrigerant vaporization heat incorporating a natural circulation method using latent heat, which is a refrigerant vaporization heat such as water, an antifreeze additive, a freon refrigerant, a natural refrigerant, and a liquefied gas. The exhaust gas contains carbon monoxide, hydrocarbons, nitrogen oxides (NOx), particulate matter (PM), and the like. In particular, nitrogen oxides (NOx) occur a lot when the fuel is completely burned. Therefore, an exhaust gas recirculation device is used to reduce the generation of nitrogen oxides by reducing the combustion temperature in the cylinder by recirculating the exhaust gas into the intake cylinder. For this purpose, an EGR cooler, a cooling device, is used to cool the exhaust gas. Equipped. However, the cooling of the EGR cooler is a common case of using a water cooling method, and when a cooling device using a refrigeration cycle using a compressor (compressor) is proposed, such as Registration No. 10-0528205. There is also. In the present invention, a method of cooling the EGR cooler uses a method of cooling the exhaust gas using evaporation heat during the boiling process of the refrigerant. Since the refrigerant is circulated using the waste heat and gravity of the exhaust gas, unlike the forced circulation method using the water-cooled pump or the compressor of the refrigeration cycle, the natural circulation method does not use energy for the refrigerant circulation, thereby greatly improving energy efficiency. In addition, since the refrigerant circulation speed is changed according to the temperature of the waste heat of the exhaust gas, the cooling performance is influenced so that the EGR cooler can be operated at a proper temperature, thereby optimizing the cooling performance. |
