在寒冷的天氣下，對(duì)車主和愛車而言都是一場嚴(yán)峻的考驗(yàn)。不少車主開始擔(dān)心冬天水箱會(huì)結(jié)冰。那么濟(jì)南哪里修奧迪比較專業(yè)廠家今天就和大家聊一聊為什么水箱會(huì)結(jié)冰，以及該如何去解決。

In cold weather, it is a severe test for owners and their cars. Many car owners are worried that the water tank will freeze in winter. So where is the most professional manufacturer of Audi in Jinan? Let's talk about why the water tank freezes and how to solve it.

為什么水箱會(huì)結(jié)冰?

Why does the water tank freeze?

其實(shí)車主們的擔(dān)憂不無道理，這是因?yàn)椴簧佘囍鳛榱耸″X，僅僅使用自來水作為車輛冷卻系統(tǒng)的傳熱介質(zhì)，這在以前是很常見的事情。由于水的冰點(diǎn)為0°C，當(dāng)溫度處于零下時(shí)，水箱以及冷卻系統(tǒng)的其它部分就會(huì)容易結(jié)冰。

In fact, the concern of car owners is not unreasonable. This is because many car owners only use tap water as the heat transfer medium of the vehicle cooling system in order to save money. This is a very common thing in the past. Since the freezing point of water is 0 ° C, when the temperature is below zero, the water tank and other parts of the cooling system will easily freeze.

為了使車輛在冬季能正常出勤，現(xiàn)在加的都是防凍冷卻液，就是具有防凍功能的冷卻液，一般由水、防凍劑和添加劑組成。其中占比大的還是水，因?yàn)樗谋葻崛葺^大并且熱傳導(dǎo)快，在吸收熱量后容易散發(fā)。不過加入一定量的防凍劑后，可以降低冷卻液的冰點(diǎn)。

In order to ensure the normal attendance of the vehicle in winter, the antifreeze coolant is added now, which is the coolant with antifreeze function, and is generally composed of water, antifreeze and additives. It is water that accounts for a large proportion, because water has a large specific heat capacity and fast heat transfer, which is easy to dissipate after absorbing heat. However, adding a certain amount of antifreeze can reduce the freezing point of the coolant.

但有時(shí)明明加的是冰點(diǎn)足夠低的防凍冷卻液，為什么水箱也會(huì)結(jié)冰呢?這個(gè)問題其實(shí)也很好解釋。冷卻液在日常的使用過程中難免會(huì)出現(xiàn)揮發(fā)，在酷熱的夏季會(huì)更加明顯。部分卡友在看到冷卻液液面高度不足時(shí)，就會(huì)加點(diǎn)自來水應(yīng)急。但是冷卻液加了水后濃度會(huì)變稀，久而久之防凍性能就會(huì)有一定的損失，從而導(dǎo)致冷卻液的冰點(diǎn)上升，無法抗住嚴(yán)寒天氣，除非一直不熄車。

But sometimes the antifreeze coolant with low freezing point is clearly added. Why does the water tank freeze? This question is actually easy to explain. The coolant will inevitably volatilize during daily use, especially in the hot summer. Some users will add tap water for emergency when they see that the coolant level is insufficient. However, the concentration of the coolant will become thinner after adding water, and the antifreezing performance will be lost over time, which will lead to the rise of the freezing point of the coolant, which cannot withstand the severe cold weather, unless the vehicle is not stopped all the time.

冷卻液結(jié)冰后該怎么辦?

What should I do after the coolant freezes?

如果遇到這種情況，首先我們不能啟動(dòng)發(fā)動(dòng)機(jī)，因?yàn)樗浣Y(jié)冰意味著整個(gè)冷卻系統(tǒng)管路內(nèi)的冷卻液都凝固了。貿(mào)然打著車輛會(huì)使水泵以及皮帶損壞，導(dǎo)致冷卻系統(tǒng)無法正常工作。冷卻系統(tǒng)損壞故障繼而會(huì)令發(fā)動(dòng)機(jī)過熱，出現(xiàn)粘缸的狀況。

In this case, we cannot start the engine at first, because the freezing of the water tank means that the coolant in the entire cooling system pipeline has solidified. The water pump and belt will be damaged if you hit the vehicle carelessly, resulting in the cooling system not working properly. If the cooling system is damaged, the engine will overheat and the cylinder will stick.

此時(shí)，我們需要仔細(xì)檢查水箱和管路的狀態(tài)。如果結(jié)冰程度嚴(yán)重，將水箱和管路脹裂，那就需要呼叫維修人員進(jìn)行零件更換。如果檢查后發(fā)現(xiàn)各部件完好，可以自行對(duì)冷卻液實(shí)施解凍。

At this time, we need to carefully check the status of the water tank and pipeline. If the water tank and pipeline are cracked due to severe icing, it is necessary to call the maintenance personnel to replace the parts. If the components are found to be in good condition after inspection, you can defrost the coolant by yourself.

為了避免冷卻液結(jié)冰的現(xiàn)象再次發(fā)生，我們應(yīng)該在冬季來臨前及時(shí)更換適宜當(dāng)?shù)丨h(huán)境溫度的冷卻液，萬一等到冷卻液結(jié)冰了再更換，機(jī)件凍壞后的維修費(fèi)用很可能會(huì)更高。一般情況下，都是根據(jù)所處地區(qū)的氣溫來選擇冷卻液型號(hào)，建議選擇冰點(diǎn)比該地區(qū)低氣溫低5°C~10°C為宜。

In order to prevent the phenomenon of coolant icing from happening again, we should replace the coolant that is suitable for the local ambient temperature in time before the winter comes. In case of replacing the coolant when it freezes, the maintenance cost of the parts after freezing is likely to be higher. Generally, the coolant model is selected according to the temperature of the region where it is located. It is recommended that the freezing point be 5 ° C~10 ° C lower than the low temperature of the region.

除了選擇合適型號(hào)的冷卻液之外，在補(bǔ)充冷卻液時(shí)也要注意，不要混加其他型號(hào)的冷卻液。因?yàn)椴煌睦鋮s液中所含的的防凍劑、添加劑是不一樣的，混合使用的話可能會(huì)產(chǎn)生未知的化學(xué)反應(yīng)，嚴(yán)重的話甚至造成冷卻液變質(zhì)和失效。不僅無法提供散熱能力，損傷發(fā)動(dòng)機(jī)，還會(huì)浪費(fèi)冷卻液。有關(guān)汽車維修或者維護(hù)的事項(xiàng)就來我們網(wǎng)站http://www.nhakhoathuduc.net咨詢吧！

In addition to selecting the appropriate type of coolant, pay attention not to mix other types of coolant when replenishing the coolant. Because the antifreeze and additives contained in different coolants are different, mixed use may produce unknown chemical reactions, or even cause deterioration and failure of the coolant. It can not only provide heat dissipation, damage the engine, but also waste coolant. Come to our website for matters related to car repair or maintenance http://www.nhakhoathuduc.net Ask!
