Embodiment

[0034] like figure 1 and figure 2 As shown, the embodiment of the present invention provides an automobile waste heat recovery evaporator, including a main casing 1, a heat exchanger 2, a bypass pipe 3 and a bypass valve 4, and the specific settings are as follows:

[0035] The main casing 1 has a cylindrical structure with open ends at both ends. The outer wall of the bottom of the main casing 1 is provided with a fixing device. The fixing device can be selected from the existing conventional fixing methods, such as hanging and horizontal installation methods. An intake diffuser 11 is installed on one end of the main casing 1, and an intake port is formed on the intake diffuser 11, and an exhaust gas collector 12 is installed on the other end of the main casing 1, and the exhaust gas collector 12 An exhaust port is formed on it to facilitate the flow of exhaust gas. The heat exchanger 2 is installed in the main shell 1, and is fitted and assembled with the main shell 1. A ...

Abstract

The embodiment of the present invention discloses an automobile waste heat recovery evaporator, which includes a main casing, a heat exchanger, a bypass pipe and a bypass valve. There is an air inlet, an exhaust port is arranged at the air outlet, and a plurality of flat finned tubes are arranged inside the heat exchanger, and the flat finned tubes are arranged in a star-shaped radial structure from the center of the main shell to the surrounding direction, bypassing The tube is arranged in the middle of the heat exchanger, and a bypass valve is set to control the bypass pipeline and the heat exchanger pipeline respectively. The invention utilizes the evaporator whose main shell is cylindrical, adopts flat finned tube heat exchange tubes, and arranges them in a star-shaped structure, so that the heat exchange is more uniform, the heat exchange efficiency is higher, and the pressure resistance is better. The structure has higher strength, and a bypass channel and a bypass valve are installed at the same time. It has a compact structure, small volume, small piezoresistance on the hot side, better shock resistance, pressure resistance and safety, that is, it can meet the basic heat exchange and evaporation functions. In addition, it also has good shock resistance and sealing performance.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobile waste heat recovery, in particular to an automobile waste heat recovery evaporator. Background technique [0002] The waste heat recovery system (WHR) has the characteristics of high energy-saving efficiency, good fuel-saving effect, and can effectively reduce NOX emissions in the energy-saving and emission-reduction technology of motor vehicles. Its application cost is relatively low, the technical difficulty is small, and the engine structure does not need to be changed. Among them, the evaporator, as the core functional module of the system, affects the work efficiency and size of the entire system. [0003] The working principle of the evaporator is to exchange heat with the organic working medium of the system through exhaust gas (cooling liquid, lubricating oil, etc.), so that the organic working medium evaporates and overheats. The overheated organic working m...
