Description

Technical Field

[0001] This utility model relates to the field of heat dissipation system technology, and in particular to an electric vehicle heat dissipation system and an electric vehicle. Background Technology

[0002] In electric vehicles (including electric motorcycles, electric bicycles, electric cars, children's electric cars, electric go-karts, and other vehicles that use batteries as a power source), the electrical components are the main heat source of the vehicle body. Controlling the temperature of the heat source can effectively improve the overall performance of the vehicle, extend the life of the electrical components, and protect the life and health of passengers.

[0003] Currently, heat dissipation in vehicle electrical systems mainly involves cooling the electrical components themselves. Cooling methods are divided into active and passive cooling: active cooling refers to the process where the heat source of the vehicle's electrical components is transferred and radiated to the cooling fins via a fluid medium, and then cooled by a cooling fan; passive cooling refers to the process where the heat source of the electrical components is transferred and radiated to the outer casing, and then cooled by airflow through the casing's cooling fins.

[0004] Of these two methods, active cooling requires a large overall size and carries the risk of coolant leakage and complex maintenance issues; passive cooling, on the other hand, is insufficient to control the temperature within a reasonable range in a timely manner. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an electric vehicle cooling system and a comprehensive solution to the current cooling problem.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A Denso heat dissipation system includes a Denso heat source, a heat conduction unit, and a heat dissipation duct connected in sequence, wherein a fan unit is arranged at the heat dissipation duct to promote airflow within the heat dissipation duct.

[0007] In the above technical solution, preferably, the electric heating source is one or more of a motor, a battery pack, a controller, and a charger.

[0008] In the above technical solution, preferably, the heat conduction unit includes one or more heat pipes, and the inner end of the heat pipe abuts against the housing of the electric heating source.

[0009] In the above technical solution, preferably, the heat conduction unit includes a mounting base assembled on the heat pipe, and the mounting base includes one or more receiving slots adapted to the heat pipe.

[0010] In the above technical solution, preferably, the outer end plate of the heat pipe is arranged in a circular shape within the heat dissipation duct of the cylindrical inner wall.

[0011] In the above technical solution, preferably, the outer wall of the heat dissipation duct is provided with an opening groove for the heat pipe to pass through.

[0013] In the above technical solution, preferably, the heat dissipation duct includes a duct window; One or more ejector holes are provided on the heat dissipation duct.

[0014] In the above technical solution, preferably, the heat dissipation duct connected to the fan unit is a duct; The fan unit is a high-speed ducted fan; The fan unit is electrically connected to a fan regulating unit for controlling the start-up, shutdown and / or speed of the fan unit. The electric heating source is equipped with a temperature detection unit that is electrically connected to the fan regulating unit, so as to control the start-up and / or speed adjustment of the fan unit according to the real-time temperature of the electric heating source. An air filter unit is provided on the gas flow path at the air inlet end of the fan unit and / or on the gas flow path at the air outlet end of the fan unit.

[0015] An electric vehicle includes an electric cooling system as described above.

[0016] The beneficial effects of this utility model are: This application directly connects to the Denso heat source via a heat conduction unit, directly transferring the heat generated by the heat source to the cooling duct. A high-velocity, high-flow-rate, low-temperature airflow generated by a high-speed ducted fan dissipates heat from the heat conduction unit and heat dissipation fins within the duct-shaped cooling duct. This results in lower thermal resistance under convection cooling conditions, effectively suppressing end flow within the duct, reducing internal noise, and improving heat dissipation efficiency. The entire structure requires no coolant, eliminating concerns about leakage and maintenance. Compared to liquid cooling, it offers better insulation, a simpler and more reliable structure, reduced system risk, and lighter weight.

[0017] This application is easy to install, can improve vehicle operating efficiency and reduce the maintenance of electrical systems. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See Figures 1-8 A Denso heat dissipation system includes a Denso heat source 1, a heat conduction unit 2, a heat dissipation duct 3, and a fan unit 4.

[0027] For the Denso heat source 1, it is one or more of the following: motor, battery pack, controller, and charger.

[0028] The heat conduction unit 2 includes one or more heat pipes 21, one end of which is mounted on the electric heating source 1 and the other end is mounted on the heat dissipation duct 3. The heat pipes 21 are connected to the electric heating source 1 to transfer the heat generated by the electric heating source 1 to the other end of the heat pipes 21.

[0029] like Figure 1 and Figure 2 As shown, this is one embodiment of the arrangement and number of heat pipes 21. A certain gap is left between adjacent heat pipes 21. The inner end of the heat pipe 21 abuts against the housing of the electric heating source 1. Furthermore, the inner end of the heat pipe 21 can be inserted into the housing of the electric heating source 1 through the through hole on the housing of the electric heating source 1 and fixed to the inner wall of the housing of the electric heating source 1. The outer end 211 of the heat pipe 21 is inserted into the heat dissipation duct 3 and coiled into a ring shape. Correspondingly, the inner cavity or inner wall of the heat dissipation duct 3 is designed as a cylinder to increase the contact area for heat convection between the outer end of the coiled heat pipe and the inner wall of the heat dissipation duct.

[0030] Furthermore, a number of heat dissipation fins 31 that contact the heat pipes 21 can be arranged on the inner wall of the heat dissipation duct 3. The heat dissipation fins 31 can be in the shape of arc strips, and multiple fins can be arranged evenly in the circumference.

[0031] To facilitate the positioning of multiple heat pipes 21, in this embodiment, the heat conduction unit 2 further includes a fixing seat 22 mounted on the heat pipes 21. The fixing seat 22 includes one or more receiving slots 221 adapted to the heat pipes. The size of the receiving slots 221 can be adaptively adjusted according to the arrangement angle and direction of the heat pipes 21. Figure 8 As shown in one embodiment, the receiving groove 221 on the fixing base 22 gradually increases from one side to the other.

[0032] In this embodiment, the heat dissipation duct 3 includes a duct opening 32 that is useful for increasing airflow. In order to facilitate the outer end of the heat pipe 21 to enter the heat dissipation duct 3, in this embodiment, an opening groove 33 for the heat pipe 21 to pass through is provided on the outer wall of the heat dissipation duct 3. As one embodiment, the opening groove 33 is in fluid communication with the duct opening 32.

[0033] In this embodiment, the fan unit 4 is installed at one end of the heat dissipation duct 3, and it provides high-pressure airflow within the duct, such as... Figures 1-4 As shown in one embodiment, the outer diameter of the end of the heat dissipation duct 3 used to install the fan unit 4 is smaller than that of the end used to install the heat pipe 21, and the two ends of different sizes are connected as one unit by a circumferentially arranged inclined wall 34.

[0034] The cooling duct connected to fan unit 4 is duct-shaped. The duct-shaped outer wall reduces the generation of end flow, so that the airflow maintains a higher average flow velocity and a more uniform flow distribution in the duct.

[0035] One or more ejector holes 35 are provided on the heat dissipation duct 3. In one embodiment, the ejector holes 35 are provided on the circumferentially arranged inclined wall 34, and there are multiple ejector holes 35, which are evenly arranged circumferentially. When the high-speed airflow passes through the ejector holes 35, a local pressure difference is generated, which drives the external airflow to merge into the main airflow from the ejector holes, increasing the overall flow rate and reducing the energy consumption of the fan.

[0036] Fan unit 4 is a high-speed ducted fan, which improves the heat exchange efficiency of the radiator by increasing the airflow velocity.

[0037] In one embodiment, the fan unit 4 is electrically connected to a fan regulating unit 41 for controlling the start-up, shutdown, and / or speed of the fan unit 4. Furthermore, the electric heating source 1 is equipped with a temperature detection unit (not shown in the figure, but it can be specifically installed on the inner or outer wall of the electric heating source 1 housing) that is electrically connected to the fan regulating unit 41. The temperature detection unit feeds back the real-time temperature of the electric heating source 1 to the fan regulating unit 41, and the fan regulating unit 41 controls the start-up, shutdown, and / or speed adjustment of the fan unit 4 according to the real-time temperature of the electric heating source 1.

[0038] In one embodiment, an air filter unit (not shown in the figure) is provided on the gas flow path at the air inlet end of the fan unit 4 and / or on the gas flow path at the exhaust end of the fan unit.

[0039] An electric vehicle includes an electric cooling system as described above.

[0040] This application innovatively uses heat pipes and ducted cooling as part of the heat dissipation system. Heat pipes are used to conduct heat from the heat-generating element into the ducted air duct, and a ducted fan that can generate high flow rate and large flow volume is used to remove the heat from the heat pipes and heat dissipation fins in the ducted air duct through thermal convection.

[0041] The fan speed is adjusted within the controllable temperature range required by the system, ensuring that the temperature of the overall heating element remains within a reasonable range. The entire system has a simple structure, is easy to assemble and maintain, and facilitates modular installation. Overall maintainability is improved while reducing the overall vehicle weight and enhancing the driving experience.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
