Technical Field

[0001] The invention belongs to the technical field of automobile cooling systems, and in particular relates to a cooling system. Background Art

[0002] The automobile cooling system is an important auxiliary system to ensure the normal and stable operation of all components of the vehicle. The automobile cooling system takes away part of the heat from heat-generating devices such as vehicle motors, batteries, and central processing units, so that the heat-generating devices are kept at an appropriate temperature and are always in good working condition.

[0003] At present, conventional traditional cooling systems need to be manufactured using injection molding or welding processes, which have problems such as high product cost, high mold cost, and short service life. Summary of the invention

[0004] In view of the above-mentioned deficiencies existing in the prior art, the present invention provides a cooling system to solve the problems of high product cost, high mold cost, short service life, etc. in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0022] Embodiment 1

[0023] like Figure 1 As shown, a cooling system includes a heat source 1, a radiator 2, a water pump 3 and an expansion kettle 4. The heat source 1 is conductively connected to the radiator 2 through the water pump 3, and the radiator 2 is conductively connected to the expansion kettle 4 through an exhaust pipe 5 and a water supply pipe 6. The expansion kettle 4 is a pressure type kettle. One end of the exhaust pipe 5 is connected to the expansion kettle 4, and the other end of the exhaust pipe 5 is connected to the radiator 2. One end of the water supply pipe 6 is connected to the expansion kettle 4, and the other end of the water supply pipe 6 is connected to the water pump 3. A cooling fan 21 is provided on the radiator 2.

[0024] The expansion kettle 4 is designed with pressure, and the expansion kettle 4 participates in the system circulation. In order to reduce the working temperature of the heat source 1, after the water pump 3 starts working, the heat of the heat source 1 is transferred to the radiator 2 through the coolant circulation, and then the cooling fan 21 on the radiator 2 transfers the heat to the atmosphere in a convection heat transfer manner. When the system starts from low temperature and the workload increases, resulting in an increase in system temperature, the system coolant expands, and the expansion kettle 4 directly participates in the system circulation.

[0025] Embodiment 2

[0026] like Figure 2 As shown, a cooling system includes a heat source 1, a radiator 2, a water pump 3 and an expansion kettle 4. The heat source 1 is conductively connected to the radiator 2 through the water pump 3, and the radiator 2 is conductively connected to the expansion kettle 4 through an exhaust pipe 5 and a water supply pipe 6. A cooling fan 21 is provided on the radiator 2. The expansion kettle 4 is a pressureless kettle. The exhaust pipe 5 and the water supply pipe 6 are arranged on the same side of the expansion kettle 4 and the radiator 2, and the exhaust pipe 5 and the water supply pipe 6 use the same pipeline, and a pressure cap 20 is provided at the highest point of the cooling system.

[0027] The expansion kettle 4 is designed without pressure, and the exhaust pipe 5 and the water supply pipe 6 are completed by one pipe. After the water pump 3 starts working, the heat of the heat source 1 is transferred to the radiator 2 through the coolant circulation, and then the cooling fan 21 on the radiator 2 transfers the heat to the atmosphere by convection heat exchange. When the system starts from low temperature and the workload increases, resulting in an increase in system temperature, the system coolant expands. When the water temperature rises and the water volume expands to cause the pressure to increase, the pressure cap 20 opens and the excess water vapor is discharged to the expansion kettle for storage. When the temperature drops, the water in the expansion kettle 4 is sucked into the main circulation system.

[0028] Embodiment 3

[0029] like Figure 3 As shown, a cooling system includes a heat source 1, a radiator 2, a water pump 3 and an expansion kettle 4. The heat source 1 is connected to the radiator 2 through the water pump 3, and the radiator 2 is connected to the expansion kettle 4 through an exhaust pipe 5 and a water supply pipe 6. A cooling fan 21 is provided on the radiator 2. The expansion kettle 4 is a pressureless kettle. A one-way valve 7 is provided at the connecting section between the water supply pipe 6 and the expansion kettle 4. One end of the exhaust pipe 5 is connected to the expansion kettle 4, and the other end of the exhaust pipe 5 is connected to the radiator 2. A pressure cap 20 is provided at the highest point of the cooling system.

[0030] The expansion kettle 4 adopts a non-pressure structure design. In order to ensure smooth water replenishment, a water replenishment pipe 6 is added. At the same time, in order to prevent the hot water from the heat source from being transferred to the expansion kettle 4 and causing the coolant to evaporate too quickly, a one-way valve 7 is added to the water replenishment 6. In order to reduce the working temperature of the heat source 1, the water pump 3 starts working and transfers the heat of the heat source 1 to the radiator 2 through the coolant circulation. Then the cooling fan 21 on the radiator 2 transfers the heat to the atmosphere by convection heat exchange. When the system starts from low temperature and the workload increases, resulting in an increase in system temperature, the system coolant expands, and the system pressure rises to the limit pressure of the pressure cap 20, the pressure cap 20 opens, and the high-temperature hot steam and excess liquid of the system expansion are discharged to the expansion kettle 4 for storage. The system can be directly injected from the expansion kettle 4 or the pressure cap 20 for the first operation. When the system is shut down and restarted, or when the water temperature drops due to reduced workload, causing the system coolant to shrink, water is sucked in and replenished directly from the water replenishment pipe through the water pump 3. When the system is full, replenishment stops automatically. The advantage of this system is that the expansion kettle 4 is not designed with pressure. At the same time, because it does not participate in the system circulation, it is ensured that the expansion kettle 4 has the characteristics of low temperature, no pressure, flexible layout, good durability, etc. during use. At the same time, the structural design and process manufacturing of the expansion kettle 4 can be simplified, and cheaper materials can be used. The expansion kettle 4 can be manufactured by processes such as blow molding, which greatly reduces material costs and mold costs. A one-way valve is used in conjunction with the system to effectively block the transfer of hot water to the kettle, which is conducive to reducing the evaporation loss of water vapor and greatly improving the service life of the cooling system.

[0031] Compared with embodiments 1 and 2, the cooling system solution effectively meets the exhaust, water replenishment and service life requirements of the cooling system. The product cost of the expansion kettle plus a one-way valve in this solution is reduced by about 50% compared with embodiment 1, and the mold cost is reduced by about 80%, which has high economic benefits.

[0032] The above is only an embodiment of the present invention. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field of the invention before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
