Heat transfer system and control method for cooling fins of an engine

Abstract

The invention discloses a cooling piece heat transmission system for an engine and a control method. A heat transmission device comprises thermoelectric cooling pieces, rotary shafts, concentric gears and transmission racks, wherein the cold surfaces of the thermoelectric cooling pieces can cool the engine, the hot surfaces of the thermoelectric cooling pieces can heat the engine, and the front wall and the rear wall of a cylinder are both connected with one line of thermoelectric cooling pieces, the rotary shafts are fixedly connected with the side faces of the thermoelectric cooling pieces, and the thermoelectric cooling pieces are driven by the rotary shafts to rotate so that the cold surfaces and the hot surfaces of the thermoelectric cooling pieces can be attached to the engine alternately; the concentric gears are fixedly connected with the rotary shafts and are concentric with the rotary shafts; the transmission racks are meshed with the concentric gears, and the transmission racks are driven by a transmission shaft of the engine to horizontally move leftwards and rightwards, so that the concentric gears are driven to rotate. The cooling piece heat transmission system for an engine and the control method have the advantages that heat can be supplied to the engine, and the engine can start at low temperature; when the engine works, the engine is cooled through the cooperation of the cooling piece heat transmission system and a cooling system of the engine.

Description

technical field [0001] The invention relates to a cooling plate heat transfer system and a control method of an engine. More specifically, the present invention relates to a cooling fin heat transfer system for heating an engine at a low temperature and cooling it at a high temperature. Background technique [0002] Winter is long in the northeast and northwest plateaus of my country. In such a low temperature environment, it is difficult or impossible to start the engine of a heavy-duty vehicle. Therefore, preheating must be carried out before starting to ensure that the engine has good starting conditions, ensure the smooth start of the engine, reduce starting wear and prolong the service life of the vehicle. [0003] At present, heaters are installed on heavy-duty vehicles in cold regions, which are used for preheating and heating before starting. The existing heater fuel pump, air pump and water pump are driven by the same motor through a linkage device, atomized and wo...

AI Technical Summary

Problems solved by technology

[0003] At present, heaters are installed on heavy-duty vehicles in cold regions, which are used for preheating and heating before starting. The existing heater fuel pump, air pump and water pump are driven by the same motor through a linkage device, atomized and work The heat exchange conditions of the medium are fixed, and the heater works at a fixed air-fuel ratio and heat exchange rate. When the ambient temperature and air pressure change, the heating efficiency decreases, and it is difficult to meet the heating requirements of typical environments in cold regions.

Secondly, in terms of control, the heating process of the heater is currently uncontrollable, and the heating mode is fixed. It is impossible to adjust the working mode of the heater according to the temperature environment of the vehicle and changes in the altitude and air pressure environment, and automatically adjust the fuel injection combustion of the heater. and heat exchange rate
