How to navigate non-tariff barriers

* Automobile engine cooling system: protect the engine from overheating With the continuous development of the automobile industry,How to navigate non-tariff barriers the performance of automobile engines is also getting stronger and stronger. However, the ensuing high temperature and high pressure environment will generate a large amount of heat during the operation of the car engine. If effective cooling measures are not taken, the engine will be damaged due to overheating. Therefore, car engines must be equipped with a cooling system to protect the engine from heating. This article will introduce in detail the composition, working principle and common problems of automobile cooling systems. I. Composition of automobile cooling system 1. The first important part of the water tank car cooling system is the water tank. The water tank is an important container used to encapsulate the coolant and is also responsible for the transportation of the coolant.Generally speaking, the water tank is made of plastic or aluminum, which has certain high temperature resistance. Two. The second component of the pump car cooling system is the water pump, which is responsible for extracting the coolant from the tank and transporting it out of the tank for consumption. A water pump usually consists of a bearing and an impeller. The bearing is responsible for rotating the impeller and the impeller is responsible for flowing liquid into the engine. 3. The third part of the radiator cooling system is the radiator. Radiators are the most common way to heat coolants. They are usually a series of small tubes. Radiators are usually made of copper or aluminum, which have good heat dissipation properties. Four. Fan is a key element of rapid cooling in the cooling system. When the radiator cannot control the temperature of the engine, the fan is activated to provide additional heat dissipation to the radiator. Fans are usually controlled by sensors.5. Heat exchanger Heat exchanger is a common point between coolers and air conditioning systems. The heat exchanger is responsible for transporting the high-temperature gas generated in the air conditioning system to the engine through a pipe, and then cooling the gas in the engine and returning it to the air conditioning system. II. The working principle of automobile cooling system The working principle of automobile cooling system is very simple. When the engine starts, the water pump starts to work, extracting the coolant from the water tank and transporting it to the engine. As the coolant arrives in the engine and flows along the cylinder channel, it absorbs heat from the engine. As the liquid heats up, it flows into the radiator through the water pipe. There are many small tubes in the radiator, and their surface area is very large and thin. Therefore, the exchange rate between the coolant and the air on the surface of the pipe is very fast. At this time, the coolant extracted by the pump has become very hot and needs to be further cooled.In order to meet this demand, there is an important component in the car cooling system: the fan. The fan dies to expand the heat dissipation area of the system and further cools the air. When more heat dissipation capacity is needed, there are also heat exchangers in the automotive cooling system. When the air conditioner is placed, these conditioners will generate a very high temperature in the air. At this time, the heat exchanger will transport high-temperature air to the car cooling system to heat the coolant and produce cold air. This is the collaboration between the car cooler and the air conditioning system. III. Common problems of automobile cooling system Although automobile cooling system has become one of the basic elements of modern cars, it will also have some common problems. 1. Engine overheating is one of the most common problems in automobile cooling systems. Insufficient heat or blockage of import and export will cause the engine to overheat and break down.Two. The pressure of the liquid used in the leaking car cooling system is very high, so any leakage in the system will cause the mixed liquid to overflow. If you see liquid on the ground after the vehicle is parked, your cooling system may be leaking. 3. The problem of the water pump is that it (or its bearing) is prone to failure due to the high frequency of use of the water pump. If the water pump fails, the hydraulic power will be reduced, and the coolant cannot be passive. In a word, the car cooling system can be regarded as a protective cover for engine life. Since it can effectively control the temperature of the engine, it can ensure that the engine will not be damaged in any way. Although this system may need more maintenance, it is obviously worth protecting the normal operation of the engine for a long time.
