[0027] The above and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings. Through the description of the specific implementation methods, the technical means and effects adopted by the present invention to achieve the predetermined purpose can be more deeply and specifically understood. However, the drawings are only for reference and explanation purposes and are not used to limit the present invention.

[0028] The terms "first", "second", etc. are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Figure 1 The figure is a schematic diagram of the temperature control structure of a vehicle-mounted computer according to an embodiment of the present invention.

[0031] like Figure 1 As shown, the temperature control structure of the vehicle-mounted computer provided in this embodiment includes a vehicle-mounted computer 11 and a main pipe 12 .

[0032] The on-board computer 11 includes a first host 111 , a water pump 112 , a five-way valve 113 , a first radiator 114 , a first solenoid valve 115 , and a fluid pipeline 116 .

[0033] The main line 12 includes a second solenoid valve 121 and a first three-way pipe 122 .

[0034] The first solenoid valve 115 is used to receive the fluid outputted by the first host 111 , and selectively communicates with the first radiator 114 or the five-way valve 113 based on a control instruction to output the fluid to the first radiator 114 or the five-way valve 113 .

[0035] The second solenoid valve 121 is used to receive the hot fluid in the main pipeline of the automobile, and selectively connects with the first three-way pipe 122 or the five-way valve 113 based on the control instruction to output the hot fluid in the main pipeline of the automobile to the first three-way pipe 122 or the five-way valve 113.

[0036] When the five-way valve 113 is connected to the first solenoid valve 115 and the second solenoid valve 121, the five-way valve 113 receives the hot fluid in the main pipeline output by the second solenoid valve 121 and the fluid output by the first solenoid valve 115. The hot fluid in the main pipeline output by the second solenoid valve 121 and the fluid output by the first solenoid valve 115 will exchange heat in the five-way valve 113, so that the five-way valve 113 can achieve the purpose of heating the fluid in the heating circulation loop.

[0037] The second solenoid valve 121 is connected to the first three-way pipe 122, so that the five-way valve 113 does not receive the hot fluid in the main pipeline. The first solenoid valve 115 is connected to the first radiator 114, so that when the first radiator 114 receives the fluid, the five-way valve 113, the water pump 112, the first host 111, the first solenoid valve 115, and the first radiator 114 form a cooling circulation loop inside the on-board computer 11 through the fluid pipeline 116 connected thereto. The fluid flow path of the cooling circulation loop is water pump 112-first host 111-first solenoid valve 115-first radiator 114-five-way valve 113-water pump 112.

[0038] The second solenoid valve 121 is connected to the five-way valve 113, and the first solenoid valve 115 is connected to the five-way valve 113, so that when the five-way valve 113 receives the hot fluid in the main pipeline and the fluid output by the first solenoid valve 115, the five-way valve 113, the water pump 112, the first host 111, and the first solenoid valve 115 form a heating circulation loop inside the on-board computer 11 through the fluid pipeline 116 connected thereto. The fluid flow path of the heating circulation loop is water pump 112-first host 111-first solenoid valve 115-five-way valve 113-water pump 112, second solenoid valve 121-five-way valve 113-first three-way pipe 122.

[0039] The water pump 112 is used to drive the fluid to flow in the heating circulation loop or the cooling circulation loop.

[0040] The first three-way pipe 122 is used to receive excess fluid in the five-way valve 113 so that the excess fluid in the five-way valve 113 flows into the main pipeline.

[0041] The first host 111 includes a first CPU 111A and a first GPU 111B. The first CPU 111A receives the fluid output by the water pump 112 and outputs the fluid to the first GPU 111B. The first GPU 111B outputs the fluid to the first solenoid valve 115. When the fluid flows through the CPU 111A and the GPU 111B, the fluid exchanges heat with the CPU 111A and the GPU 111B to take away the heat generated by the CPU 111A and the GPU 111B, or heats the CPU 111A and the GPU 111B.

[0042] The first radiator 114 includes a cooling fan for increasing the heat exchange efficiency between the first radiator 114 and air.

[0043] In one embodiment, the temperature control structure of the on-board computer also includes a water supply pot, which is connected to the first radiator 114 through a fluid pipe 116. When the fluid in the cooling circulation loop is insufficient, the fluid stored in the water supply pot can be supplemented into the cooling circulation loop through the fluid pipe 116 to ensure the normal operation of the cooling circulation loop.

[0044] The temperature control structure of the vehicle-mounted computer provided by the present invention can enable the vehicle-mounted computer to form a cooling circulation loop or a heating circulation loop, which can not only allow the vehicle-mounted computer to dissipate heat and cool normally, but also allow the vehicle-mounted computer to adapt to extreme temperatures, thereby increasing the service life of the vehicle-mounted computer.

The flow path of the fluid in the fluid pipeline 116 is water pump 112-third solenoid valve 118-first main unit 111-second three-way pipe 1111-first solenoid valve 115-five-way valve 113-water pump 112. After the second solenoid valve 121 is connected to the five-way valve 113, the excess fluid in the five-way valve 113 will flow back to the main pipeline through the first three-way pipe 122.

[0056] When the third solenoid valve 118 is connected to the water pump 112 and the second main engine 117, the first solenoid valve 115 is connected to the second three-way pipe 1111 and the first radiator 114, and the second solenoid valve 121 is connected to the first three-way pipe 122, the five-way valve 113, the water pump 112, the third solenoid valve 118, the second main engine 117, the second three-way pipe 1111, the first solenoid valve 115, the first radiator 114, and the second radiator 119 form a cooling circulation loop for the second main engine 117 through the fluid pipeline 116 connected thereto.

The five-way valve 113, the water pump 112, the third solenoid valve 118, the second main engine 117, the second three-way pipe 1111, and the first solenoid valve 115 form a heating circulation loop for the second main engine 117 through the fluid pipeline 116 connected thereto. The flow path of the fluid in the fluid pipeline 116 is water pump 112-third solenoid valve 118-second main engine 117-second three-way pipe 1111-first solenoid valve 115-five-way valve 113-water pump 112.

The controller 64 obtains the in-vehicle temperature sent by the in-vehicle temperature sensor 61 through the hard line 62. When the controller 64 recognizes through the CAN line that the host 65 is turned on, it sends a control signal to the junction box 67 according to the in-vehicle temperature sent by the temperature sensor 61, so that the junction box 67 controls the on and off states of the relays 1671, relays 2672, and relays 3671 inside it according to the received control signal.

[0097] In one embodiment, the controller 64 sends a control signal to the junction box 67 based on the CPU temperature and the startup status sent by the host 65 .
