[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0024] See also Figure 1 and Figure 2 As shown, a radiator of an embodiment of the present invention comprises a radiator core 1, a water inlet chamber 2, a water outlet chamber 3 and a temperature control switch, wherein the radiator core 1 is divided into a plurality of sub-cores, the interior of the water inlet chamber 2 is divided into a plurality of sub-water chambers connected in sequence, the plurality of sub-water chambers are connected to the plurality of sub-cores one by one, and the temperature control switch is provided at the connection point between every two adjacent sub-water chambers, the opening temperatures of the plurality of temperature control switches are increased in sequence, and the water outlet chamber 3 is respectively connected to the plurality of sub-cores.

[0025] Specifically, the radiator may include a radiator core 1, a water inlet chamber 2 and a temperature control switch. The radiator core 1 may be divided into multiple sub-cores. The interior of the water inlet chamber 2 may be divided into multiple sub-water chambers, and the multiple sub-water chambers may be connected to the multiple sub-cores one by one. A temperature control switch may be provided at the connection point between two adjacent sub-water chambers. The temperature control switch may be used to control the connection or disconnection between two adjacent sub-water chambers, and the opening temperatures of the multiple temperature control switches increase sequentially.

[0026] When the car starts to start, the water temperature of the engine is lower than the operating temperature, and the first temperature control switch in the water inlet chamber 2 is in the closed state, so that only one sub-core participates in the heat dissipation, which can reduce the heat taken away by the radiator and make the water temperature of the engine reach the appropriate operating temperature more quickly. For example, the most suitable operating temperature of the engine is 100°C, and the water temperature of the first temperature control valve can be set to about 95°C to ensure that the water temperature of the engine is close to the most suitable operating temperature. The first temperature control switch can be opened to allow other sub-cores to participate in the heat dissipation, ensuring that the water temperature of the engine is maintained at around the normal operating temperature. The engine water temperature can be accurately controlled to achieve the purpose of reducing energy consumption.

[0027] See also Figure 1 and Figure 2 As shown, in some embodiments, the radiator core 1 includes a first sub-core 11, a second sub-core 12 and a third sub-core 13, and the water inlet chamber 2 includes a first sub-water chamber 21, a second sub-water chamber 22 and a third sub-water chamber 23, and the first sub-water chamber 21, the second sub-water chamber 22 and the third sub-water chamber 23 are respectively connected to the first sub-core 11, the second sub-core 12 and the third sub-core 13 in a one-to-one correspondence.

[0028] Specifically, the radiator core 1 may include a first sub-core 11, a second sub-core 12 and a third sub-core 13, and the first sub-core 11, the second sub-core 12 and the third sub-core 13 may be arranged side by side in sequence, the water inlet chamber 2 may include a first sub-water chamber 21, a second sub-water chamber 22 and a third sub-water chamber 23, and the first sub-water chamber 21, the second sub-water chamber 22 and the third sub-water chamber 23 may also be arranged side by side in sequence, and the first sub-water chamber 21, the second sub-water chamber 22 and the third sub-water chamber 23 may be connected to the first sub-core 11, the second sub-core 12 and the third sub-core 13 in a one-to-one correspondence, respectively. Figure 2 The arrows in the figure respectively indicate the water flow directions in the first sub-core 11, the second sub-core 12 and the third sub-core 13.

[0029] When the car is started, the water flow in the engine can flow into the first sub-core 11 through the first sub-water chamber 21 for heat dissipation, which limits the core area involved in heat dissipation and can reduce the heat taken away by the radiator, so that the water temperature of the engine can quickly rise to the operating temperature. As the water temperature of the engine rises, the water flow in the engine can also flow into the second sub-core 12 and the third sub-core 13, so that the second sub-core 12 and the third sub-core 13 can also participate in heat dissipation, increasing the core area for heat dissipation, ensuring that the water temperature of the engine will not rise too high, and avoiding damage to key components of the engine due to overheating.

[0030] See also Figures 1 to 3 As shown, in some embodiments, the temperature-controlled switch includes a first temperature-controlled switch 4 and a second temperature-controlled switch 5. The first temperature-controlled switch 4 is provided at the connection between the first sub-water chamber 21 and the second sub-water chamber 22, and the second temperature-controlled switch 5 is provided at the connection between the second sub-water chamber 22 and the third sub-water chamber 23.

[0031] Specifically, the temperature control switch may include a first temperature control switch 4 and a second temperature control switch 5. The first temperature control switch 4 can be set at the connection between the first sub-water chamber 21 and the second sub-water chamber 22, and the second temperature control switch 5 can be set at the connection between the second sub-water chamber 22 and the third sub-water chamber 23. The opening temperatures of the first temperature control switch 4 and the second temperature control switch 5 are different, so that the first sub-water chamber 21, the second sub-water chamber 22 and the third sub-water chamber 23 can be connected in sequence according to the water temperature of the engine, so that the first sub-core 11, the second sub-core 12 and the third sub-core 13 can participate in heat dissipation in sequence, thereby further accurately controlling the water temperature of the engine.

[0032] See also Figure 1 and Figure 2 As shown, in some embodiments, the first sub-water chamber 21 is provided with a water inlet 24 , and the opening temperature of the first temperature-controlled switch 4 is lower than the opening temperature of the second temperature-controlled switch 5 .

[0033] Specifically, the first sub-water chamber 21 may be provided with a water inlet 24, and the water outlet pipe of the engine may be connected to the water inlet 24 of the first sub-water chamber 21, so that when the car is turned on, the water flow of the engine first flows into the first sub-water chamber 21 through the water inlet 24, and then flows from the first sub-water chamber 21 to the first sub-core 11 for heat dissipation. Since the opening temperature of the first temperature control switch 4 is lower than the opening temperature of the second temperature control switch 5, when the engine water temperature rises to a temperature close to the working temperature, the first temperature control switch 4 is opened, so that the first sub-water chamber 21 is connected with the second sub-water chamber 22, and the water flow of the engine can flow into the second sub-water chamber 22, and then flow from the second sub-water chamber 22 to the second sub-core 12, so that the second sub-core 12 participates in heat dissipation, which can avoid the insufficient heat dissipation capacity of the first sub-core 11 alone, resulting in the engine water temperature exceeding the working temperature.

[0034] And when the water temperature of the engine continues to rise and is about to approach the water temperature limit of the engine, the second temperature control switch 5 is turned on, so that the second sub-water chamber 22 is connected to the third sub-water chamber 23, and the water flow of the engine can flow into the third sub-water chamber 23, and flow from the third sub-water chamber 23 into the third sub-core 13, so that the third sub-core 13 participates in the heat dissipation, which can further increase the heat dissipation capacity and prevent the water temperature of the engine from exceeding the limit.

[0035] In some embodiments, the opening temperature of the first temperature-controlled switch 4 is lower than a first preset temperature, the opening temperature of the second temperature-controlled switch 5 is lower than a second preset temperature, and the first preset temperature is lower than the second preset temperature.

[0036] Specifically, the opening temperature of the first temperature control switch 4 can be lower than the first preset temperature. The most suitable operating temperature of a conventional engine is 100°C. The opening temperature of the first temperature control switch 4 can be set to about 95°C. Preferably, the first preset temperature is 95°C, so that when the water temperature of the engine is close to the operating temperature, the first temperature control switch 4 can be turned on, so that the second sub-core 12 participates in heat dissipation, thereby preventing the engine water temperature from exceeding the most suitable operating temperature.

[0037] The opening temperature of the second temperature control switch 5 is lower than the second preset temperature. The limit temperature of the conventional engine water temperature is 120°C. The opening temperature of the second temperature control switch 5 can be set to be lower than 120°C. Preferably, the second preset temperature is 110°C, so that when the water temperature block of the engine is close to the limit temperature, the second temperature control switch 5 can be turned on, so that the third sub-core 13 participates in the heat dissipation, thereby preventing the engine water temperature from exceeding the limit temperature and causing damage to engine components due to overheating.

[0038] See also Figure 2 As shown, in some embodiments, the volume of the second sub-core 12 is greater than the volume of the first sub-core 11 , and greater than the volume of the third sub-core 13 .

[0039] Specifically, the volume of the second sub-core 12 can be greater than the volume of the first sub-core 11, and the volume of the second sub-core 12 can also be greater than the volume of the third sub-core 13. Preferably, the volume of the first sub-core 11 is equal to the volume of the third sub-core 13, and the volume of the second sub-core 12 is equal to twice the volume of the first sub-core 11.

[0040] To be more clear, due to the low ambient temperature in most cities, in order to quickly raise the engine water temperature to the optimal operating temperature range, the first sub-core 11 is recommended to be 1 / 4 of the entire radiator core 1, and the second sub-core 12 is the area for stabilizing the engine water temperature. It is recommended that the second sub-core 12 be 1 / 2 of the entire radiator core 1, which can ensure that all heat dissipation capacity is released in advance under harsh working conditions to prevent the water temperature from approaching the limit temperature. The above specific area divisions can be corrected according to the specific matching engine operating water temperature value.

[0041] See also Figure 1 and Figure 2 As shown, in some embodiments, the radiator also includes a water outlet chamber 3, the water inlet chamber 2 and the water outlet chamber 3 are respectively arranged at opposite ends of the radiator core 1, and one end of the sub-core is connected to the corresponding sub-water chamber, and the other end of the sub-core is connected to the water outlet chamber 3.

[0042] Specifically, the radiator can also include a water outlet chamber 3, the water inlet chamber 2 and the water outlet chamber 3 can be respectively arranged at the opposite ends of the radiator core 1, and one end of each sub-core can be connected to the corresponding sub-water chamber, and the other end of the sub-core can be connected to the water outlet chamber 3, which can facilitate the water flow of the engine to flow in and out of the radiator, and circulate the water flow of the engine to dissipate heat.

[0043] In some embodiments, a connecting passage is provided at the connecting point of two adjacent sub-water chambers, the temperature control switch is arranged in the connecting passage, and the temperature control switch is used to open or close the connecting passage.

[0044] Specifically, two adjacent sub-water chambers may be provided with a connecting channel, and the temperature control switch may be installed in the connecting channel. In this embodiment, the temperature control switch is similar to the thermostat of the engine. The temperature control switch may include a wax bag mechanical type, an electronically controlled type, or other similar structures. Before the water temperature reaches the melting temperature of the wax bag, the temperature control switch is in a closed state. When the water temperature rises and the wax bag melts, it pushes the piston rod. The piston rod pushes the sensor to move, opening the sealing port, so that the two adjacent sub-water chambers are connected.
