a temperature control device

Abstract

The invention relates to the technical field of automobiles, in particular to a temperature control device, which includes an exhaust pipe, an air inlet and an exhaust port are arranged on the exhaust pipe, and a catalyst is arranged on the exhaust pipe; the temperature control coil is arranged on The outer side of the catalyst; the heating component, which communicates with the air inlet and the exhaust port respectively, can exchange heat between the gas heated by the temperature control coil and the engine, so that the temperature of the engine rises; the first cooling component, one end is connected to the exhaust The second cooling assembly communicates with the exhaust port at one end and the atmosphere at the other end, which can Cool the outside air and make the cooled gas flow through the temperature control coil to exchange heat with the catalyst, so that the temperature of the catalyst is lowered. The invention can regulate the temperature of the engine, thereby assisting the starting and normal operation of the engine.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a temperature control device. Background technique [0002] It is difficult to start the vehicle in low temperature environment. The main reason for the difficulty in starting is that the temperature of the engine oil and cooling water is too low: 1) When the temperature of the vehicle is below -20°C, the oil fluidity is poor, and the starting resistance of the engine is significantly increased, resulting in continuous start failure; 2) The temperature of the cooling water is low, resulting in The high temperature condition of the engine cylinder combustion chamber is difficult to establish. [0003] At present, there are generally the following methods for starting outdoor vehicles in low-temperature environments: 1) Repeated starting, try several times; 2) Idle for a long time after starting, and start driving after the water temperature and oil temperature rise; 3) Use an...

AI Technical Summary

Problems solved by technology

However, these methods have problems such as poor safety and large wear and tear of parts, and the temperature of the coolant and engine oil is too low, which also has adverse effects on the fuel consumption and emissions of the car.

[0004] In addition, when the vehicle is running at high speed and heavy load, the exhaust temperature will be very high, which will increase the fuel consumption of the car.
