Example Embodiment
[0026] Example one:
[0027] This embodiment is a tandem exhaust gas recirculation cooler for medium and heavy vehicles, including: an intake pipe box 3 connected to an engine exhaust pipe, an exhaust pipe box 4 connected to an intake pipe of an engine exhaust gas recirculation system, and an intake pipe box At least two heat exchange tube body assemblies are connected to the exhaust pipe box through ridge rings. The heat exchange tube body assembly 1 connected to the air inlet pipe box is provided with a water inlet pipe 5 and a heat exchange tube connected to the air outlet pipe box. The body assembly 2 is provided with a water outlet pipe 6. The heat exchange tube assembly is connected by a heat exchange tube connector 21 that connects to the gas path, and is connected to the water path through a water path connector 7.
[0028] The heat exchanger described in this embodiment may have two heat exchange tube body assemblies, or may be composed of three, four or more heat exchang...
Example Embodiment
[0035] Embodiment two:
[0036] This embodiment is an improvement of the first embodiment. It is about the refinement of the heat exchange tube assembly, such as image 3 Shown. The heat exchange tube assembly described in this embodiment includes a tube shell 1 with a rectangular or circular cross-section surrounded by metal plates. The two ends of the tube shell opening are welded with end plates 8 respectively, and a circulating exhaust gas is installed between the two end plates. The multiple heat exchange tubes9.
[0037] The heat exchange tube assembly described in this embodiment is similar to a small heat exchanger, and also has a tube shell, heat exchange tubes and tube plates, but the tube plates are called end plates for the sake of distinction. The cross section of the heat exchange tube can have various shapes, which can be round, flat, oval, etc. The surface of the heat exchange tube may have inwardly recessed grooves to improve the heat exchange efficiency of the h...
Example Embodiment
[0040] Embodiment three:
[0041] This embodiment is a refinement of the second embodiment, and is a refinement of the second embodiment about the shell, such as Figure 4 , 5 Shown. The tube shell described in this embodiment is enclosed by two sections of metal plates connected by a ridge ring.
[0042] The shell can be made of one piece of metal plate or two metal plates, and the middle is directly welded or connected by a ridge ring or connected by a flange. In this embodiment, a ridge ring is used to connect the two tube shells 12 and 13. The ridge ring 14 described in this embodiment is a metal ring with a shape corresponding to the tube shell and with a step for inserting the end surface of the tube shell. The tube shell with ridge ring has the function of resisting thermal stress.
