Waste heat recycling device for engine oil of automobile

Abstract

The invention discloses a waste heat recycling device for engine oil of an automobile, and belongs to the field of waste heat recycling technologies. The waste heat recycling device has the advantages that recycled waste heat of the engine oil is used for low-temperature starting running of the automobile; the waste heat recycling device comprises a heat storage and exchanger device (1), phase-change heat storage materials (3) are loaded in the heat storage and exchange device (1), independent heat exchange units are arranged in the heat storage and exchange device (1), and the heat is outwardly transferred and circulated by the independent heat exchange units via different heat-conduction working media and different circulating pipelines, so that objects can be heated; the engine oil is used as a heat-conduction working medium, so that the heat can be transferred into the heat storage and exchange device (1) via the corresponding heat exchange units, and can be recycled and stored in the phase-change heat storage materials (3), the stored heat also can be outwardly transferred, preheated engine oil is pumped into a main oil passage of an engine and flows into various friction pairs, a body of the engine is simultaneously preheated, the engine can be started at a low temperature advantageously, and starting abrasion of the engine is greatly reduced; cooling water further can be preheated to be used for preheating the body of the engine at a low temperature; the waste heat of the engine oil can be effectively recycled, the waste heat recycling device is energy-saving and environment-friendly, and is simple in structure, easy to implement, convenient to install and apply, low in cost and applicable to various motor vehicles, influence on an original vehicle design is prevented, and standard and industrial production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of waste heat recovery and utilization, and relates to a waste heat recovery and utilization device of automobile engine oil. Background technique [0002] When the car is running, the oil is pumped from the oil pan of the engine to the main oil passage of the engine through the oil filter and oil radiator through the oil pump and enters each friction pair to lubricate the rotating and transmission parts of the engine to reduce wear and prolong the life of the engine. The service life of the engine, the temperature of the engine oil during the lubrication process can be as high as nearly 100 ℃, and the high-temperature engine oil automatically circulates back into the oil pan. After repeated operations, the car will not only consume engine oil during long-term operation, but also the engine oil that has been lubricated and heated is cooling The middle and the outside continue to let go of the waste heat in v...

AI Technical Summary

Problems solved by technology

In view of the particularity and specificity of the operation of the car, the waste heat of the guide oil is largely discontinuous, unstable and uncertain. So far, there has been no technology to recover and utilize the waste heat of the oil.
