Embodiment Construction

[0033] As for the reference numerals in the drawings, the same or similar reference numerals are used to designate the same or similar components. In the following description, various operating parameters and components are described in various embodiments. These specific parameters and components are included herein as examples only and are not meant to be limiting.

[0034] The inventors have recognized that due to the need for improved engine fuel economy, there is a need to provide an engine waste heat recovery system that utilizes exhaust heat from the engine to reduce the time it takes for the engine to reach optimum operating temperature and utilizes the limited energy in the vehicle. space, thereby meeting the requirements for packaging space in modern vehicle designs.

[0035] This specification describes a heat recovery device and assembly for vehicles, which utilizes thermal expansion brackets arranged between the exhaust pipe segment and the coolant pipe stage, w...

Abstract

The invention discloses an exhaust heat recovery assembly for a vehicle, comprising: an exhaust pipeline segment; a coolant pipeline segment; and a thermal expansion bracket, wherein the thermal expansion bracket is located between the exhaust pipeline segment and the coolant Between the pipeline sections, the thermal expansion bracket is connected with the exhaust pipeline section and the coolant pipeline section and limits the vertical distance between the exhaust pipeline section and the coolant pipeline section.

Description

【Technical field】 [0001] The invention relates to a heat recovery device for a vehicle and its assembly. 【Background technique】 [0002] Generally, it is desirable to bring the engine temperature up to a predetermined temperature as soon as possible during a vehicle cold start condition to achieve better fuel economy. However, it is difficult to achieve the engine warm-up in the desired short time. Additionally, during cold weather conditions, there may be a need for cabin heating, which also extends the time the engine runs before reaching its optimum temperature. On the other hand, the heat in the engine exhaust is not used efficiently. 【Content of invention】 [0003] According to one aspect of the present invention, a heat recovery device for heat exchange between a vehicle exhaust and an engine coolant circuit is disclosed, comprising: a coolant line segment containing a coolant line; The thermal expansion bracket is set according to the length of the road segment; ...
