[0022] Embodiment one

[0023] As Figure 1 Indicated, a cooling system, including heat source 1, radiator 2, water pump 3 and expansion water pot 4, heat source 1 is connected through water pump 3 with radiator 2, radiator 2 is connected through exhaust pipe 5 and water supply pipe 6 with expansion water pot 4, expansion water pot 4 is pressure type water pot, exhaust pipe 5 one end is connected expansion water pot 4, and exhaust pipe 5 other end is connected radiator 2, water supply pipe 6 one end is connected expansion water pot 4, and water supply pipe 6 other end is connected water pump 3, be equipped with cooling fan 21 on radiator 2.

[0024] Expansion water pot 4 is designed with pressure, expansion water pot 4 participates in system circulation, in order to reduce the working temperature of heat source 1, water pump 3 starts working and the heat of heat source 1 is circulated to radiator 2 through cooling liquid, then cooling fan 21 on radiator 2 passes heat to atmosphere in the way of convection heat exchange, when system starts from low temperature to work load increases and thus leads to system temperature increase, system cooling liquid expands, expansion water pot 4 directly participates in system circulation.

[0025] Embodiment two

[0026] As Figure 2 Indicated, a cooling system, including heat source 1, radiator 2, water pump 3 and expansion water pot 4, heat source 1 is connected through water pump 3 with radiator 2, radiator 2 is connected through exhaust pipe 5 and water supply pipe 6 with expansion water pot 4, be equipped with cooling fan 21 on radiator 2, expansion water pot 4 is pressure type water pot, exhaust pipe 5 and water supply pipe 6 are located expansion water pot 4 and radiator 2 same side, and exhaust pipe 5 and water supply pipe 6 use same pipe, and the highest point of cooling system is equipped with pressure cover 20.

[0027] The expansion tank 4 is not pressurized. The exhaust pipe 5 and the water supply pipe 6 are connected by a single pipe. After the water pump 3 starts working, the heat from the heat source 1 is transferred 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. When the system starts from a low temperature and the working load increases, the system temperature increases and the system coolant expands. When the water temperature rises and the water volume expands, causing the pressure to rise, the pressure cap 20 opens and the excess water vapor is discharged into the expansion tank for storage. When the temperature drops, the water in the expansion tank 4 is drawn into the main circulation system.

[0028] Example 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 tank 4. The heat source 1 is connected to the radiator 2 via the water pump 3. The radiator 2 is connected to the expansion tank 4 via an exhaust pipe 5 and a water supply pipe 6. The radiator 2 is equipped with a cooling fan 21. The expansion tank 4 is an unpressurized water tank. A one-way valve 7 is provided at the connection section between the water supply pipe 6 and the expansion tank 4. One end of the exhaust pipe 5 is connected to the expansion tank 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 water kettle 4 adopts a non-pressure structure design, in order to ensure smooth water replenishment, a water replenishment pipe 6 is added, and in order to avoid heat conduction of hot water of the heat source to the expansion water kettle 4 and cause the cooling liquid to evaporate too fast, a one-way valve 7 is added to the water replenishment pipe 6, in order to reduce the working temperature of the heat source 1, after the water pump 3 is started to work, the heat of the heat source 1 is circulated to the radiator 2 through the cooling liquid, and then the cooling fan 21 on the radiator 2 circulates the heat to the atmosphere in the form of convection heat exchange, when the system is started from low temperature to working load increase and thus causes the system temperature to increase, the system cooling liquid expands, the system pressure rises to the limit pressure of the pressure cover 20, the pressure cover 20 is opened, and the high-temperature hot steam and the excess liquid of the system expansion are discharged to the expansion water kettle 4 for storage, the system can be filled with cooling liquid 1 by directly injecting from the expansion water kettle 4 or the pressure cover 20 at the first time of operation, and the water pump 3 is started to circulate and continuously replenish water to ensure that the system is full of cooling liquid 1, when the system is stopped and restarted or the water temperature is reduced due to the reduction of working load, the water pump 3 is started to sequentially directly suck water from the water replenishment pipe for replenishment, and the system automatically stops replenishment when the system is full. The advantage of the system is that the expansion water kettle 4 is designed without pressure, and because it does not participate in the system circulation, the expansion water kettle 4 has the characteristics of low temperature, no pressure, flexible arrangement, good durability and the like during use, and the structure design and process manufacturing of the expansion water kettle 4 can be simplified, more inexpensive materials can be used, and the manufacturing of the expansion water kettle 4 can be completed by using a blow molding process, which greatly reduces the material cost and mold cost, and the one-way valve is used in cooperation with the system, which effectively blocks the hot water from being transferred to the water kettle, which is beneficial to reducing the evaporation loss of water vapor and greatly improving the service life of the cooling system.

[0031] Compared with examples one and two, the cooling system scheme effectively meets the exhaust, water replenishment and service life of the cooling system, the product cost of the expansion water kettle plus the one-way valve in the scheme is reduced by about 50% compared with example one, the mold cost is reduced by about 80%, and the economic benefit is higher.

[0032] The above is only an embodiment of the present application, and the common knowledge of specific structures and characteristics in the scheme is not described in detail, the ordinary skilled person in the art knows all the ordinary technical knowledge in the technical field of the present application before the application date or the priority date, can know all the prior art in the field, and has the ability to apply conventional experimental means before that date, the ordinary skilled person in the art can perfect and implement the present scheme based on the enlightenment given in the present application, and some typical known structures or known methods should not be an obstacle for the ordinary skilled person in the art to implement the present application. It should be noted that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
