The "high temperature problem of cars" that has been hotly discussed on the Internet recently has attracted widespread attention. This article combines popular data in the past 10 days to provide you with a structured guide from cause analysis to solutions.
1. Top 5 most popular car high temperature problems on the Internet (last 10 days)
| Ranking | hot topics | Number of discussions (10,000) | main focus |
|---|---|---|---|
| 1 | Formaldehyde exceeds the standard after being exposed to the sun in the car | 12.5 | Health risks, testing methods |
| 2 | New energy vehicle battery high temperature warning | 9.8 | Battery life attenuation, cooling system |
| 3 | Engine overheats and stalls | 7.3 | Troubleshooting and maintenance costs |
| 4 | Tire puncture accidents increase | 6.1 | Tire pressure management, replacement cycle |
| 5 | Air conditioning cooling efficiency decreases | 5.4 | Refrigerant replenishment and filter element cleaning |
2. Solutions to the core problem of vehicle high temperature
1. Quick cooling techniques in the car
•convection method: Open the passenger window and repeatedly open and close the main door 5 times, which can reduce the temperature by 8-10℃ (actual measurement data)
•shading equipment: Using reflective sun visors can reduce dashboard temperature by more than 40%
•smart device: Remotely start the air conditioning function (requires vehicle support) to cool down in advance
2. Protection measures for key components
| parts | Danger temperature | Protection plan |
|---|---|---|
| Power battery | >50℃ | Avoid driving immediately after fast charging |
| engine oil | ＞130℃ | Change summer special engine oil |
| tires | >70℃ | Maintain standard tire pressure of 2.2-2.5bar |
3. Emergency handling guide
•Water temperature alarm: Stop immediately and idle to dissipate heat. It is strictly prohibited to add cold water directly.
•Battery overheated: Turn off all electrical equipment and contact after-sales inspection
•Signs of spontaneous combustion: Use a fire extinguisher to spray at the root of the fire source (note: new energy vehicles require a special fire extinguisher)
3. Comparison of effective cooling solutions measured by car owners
| method | Cost | Cooling range | duration |
|---|---|---|---|
| traditional sunshade | 20-50 yuan | 5-8℃ | 2 hours |
| Solar car fan | 150-300 yuan | 3-5℃ | Continuous ventilation |
| Liquid CO2 quick coolant | 30 yuan/can | 15℃(instantaneous) | 10 minutes |
4. Expert advice
1. Check the coolant level every day. In summer, it is recommended to check the cooling system every 5,000 kilometers.
2. Avoid leaving lighters, power banks and other flammable objects in the car during hot weather
3. New energy vehicle owners should pay attention to the latest version of the "Guidelines for High Temperature Use of Electric Vehicles" issued by the state.
Through the above structured solutions, the problem of high temperature in summer vehicles can be effectively dealt with. It is recommended that car owners choose appropriate protective measures based on their own vehicle conditions to ensure driving safety and comfort.
