Description

Technical Field

[0001] The present invention relates to the field of heat dissipation of new energy power modules, and more specifically, to a radiator that utilizes a heat pipe and a liquid cooling structure to achieve coupled heat dissipation. Background Art

[0002] In the field of new energy vehicles, heating elements serve as the core carriers of power transmission and control. Their technological evolution is deeply coupled with the efficiency of the powertrain system and the reliability of charging equipment. The rapid expansion of the industry is driving technological breakthroughs in high-power components. The current technology evaluation system focuses on five dimensions: power semiconductor device performance, packaging process reliability, manufacturing cost control, and module lightweighting. As the power system of new energy vehicles evolves towards high integration and high power density, the new generation of power modules not only need to withstand the harsh working conditions of kilovolt voltage and kiloampere current, but also need to double the heat dissipation efficiency under the physical limitation of 40% volume compression. This escalating contradiction between miniaturization and heat dissipation needs is driving the industrialization of third-generation thermal management technologies such as phase change cooling and microchannel heat dissipation.

[0003] Existing liquid cooling and heat pipe coupling schemes often use a static parallel structure. The condenser section of the heat pipe only passively contacts the liquid flow, resulting in low turbulence intensity in the cooling liquid. This prevents phase change heat transfer and liquid cooling from fully synergizing, which can lead to insufficient cooling of local hot spots. To address this issue, we propose a radiator that achieves coupled heat dissipation using heat pipes and a liquid cooling structure. Summary of the Invention

[0004] The present invention provides a radiator that uses a heat pipe and a liquid cooling structure to achieve coupled heat dissipation, thereby solving the technical problems in related technologies in which the heat pipe condensation section only passively contacts the liquid flow, the turbulence intensity of the cooling liquid is low, the phase change heat transfer and liquid cooling fail to deeply coordinate, and local hot spots are easily cooled.

[0005] The present invention provides a radiator that utilizes a heat pipe and a liquid cooling structure to achieve coupled heat dissipation, comprising: a radiator box, a skived-tooth radiator sealed and fixed to the top of the radiator box, the skived-tooth radiator comprising a heat dissipation base plate, a plurality of gantry-shaped skived-tooth blades arranged vertically on the lower wall of the heat dissipation base plate, a cooling liquid auxiliary spray assembly, and a cooling liquid flow control assembly;

[0006] The heat dissipation base plate is exposed outside the top plate of the radiator box and serves as the base surface for installing the heating element. The skived blades are vertically immersed in the inner cavity of the radiator box. The cold liquid flow control component is arranged at the liquid inlet end of the radiator box and is configured to split the coolant into a dual-channel input of an upper steady-state liquid replenishment flow and a lower pulse jet flow.

[0007] The coolant spray kit includes:

[0008] Several flushing columns are arranged obliquely in the opposite direction of the main flow direction of the coolant, and a piston drive structure is provided inside the columns;

[0009] Several n-type heat pipes, the evaporation end of which is embedded in the heat dissipation base plate, and the condensation section is connected to the liquid outlet end of the flushing column;

[0010] When the pulse jet forms a wavy liquid flow to impact the flushing liquid column, the piston is driven to inject the coolant into the outer wall of the condensation end of the heat pipe in a quantitative manner. The condensation efficiency of the heat pipe is enhanced through liquid cooling, and the heat exchange of the surface area of ​​the skive teeth and the phase change heat transfer of the heat pipe are coordinated to achieve three-stage composite heat dissipation. The inner cavity of the radiator box forms a heat conduction path with the external heating element through the heat dissipation base plate.

[0011] Furthermore, a cold liquid inlet is fixedly provided at the liquid inlet end of the outer wall of the radiator box, a control pump is connected to the cold liquid inlet, and a cold liquid outlet is connected to the liquid outlet end of the radiator box. The control pump is controlled by the system and controls the flow rate of the cold liquid injected into the radiator box as the temperature of the heating element installed on the heat dissipation base plate changes.

[0012] Furthermore, the cold liquid flow control assembly includes a liquid control box, which is fixed to the liquid inlet end of the inner wall of the radiator box. The upper inner layer of the liquid control box is a diversion chamber, in which a liquid infusion pipe and a flushing pipe are provided. Both the liquid infusion pipe and the flushing pipe are interconnected with the cold liquid inlet, and the liquid outlet end of the liquid infusion pipe passes through the side wall of the liquid control box.

[0013] Furthermore, the lower layer of the interior of the liquid control box is a pressure wave-making chamber, which is connected to the flushing pipe. A rubber elastic bag is arranged inside the pressure wave-making chamber. A wave-making plate is rotatably arranged on the outer wall of the liquid outlet end of the pressure wave-making chamber. An arc-shaped spring is fixedly arranged on the outer wall of the wave-making plate. The end of the spring away from the wave-making plate is fixedly connected to the outer wall of the diversion chamber.

[0014] Furthermore, the shovel tooth piece is divided into two parts, the side close to the heat dissipation base plate is a solid plate, and the side away from the heat dissipation base plate is a gantry frame. Some of the flushing columns are exposed in the gantry frame, and some are embedded in the solid plate.

[0015] Furthermore, a pressure piston is slidingly provided inside the flushing column, a piston column is fixedly provided below the pressure piston, and a water wave plate is fixedly provided at the bottom end of the piston column. The water wave plate is an inclined structure, forming an angle of 45° with the direction of the cold liquid flow, and a number of liquid inlet holes are opened on the outer wall of the flushing column in the gantry frame.

[0016] Furthermore, the arc-shaped end of the heat pipe is the evaporation end, and the vertical end is the condensation section. Condensate columns are fixedly provided on the outside of the two condensation ends of the heat pipe. The condensate columns are hollow cone-shaped, and the outer walls of the condensate columns are provided with several drainage holes.

[0017] Furthermore, the condensate column is immersed in the shovel tooth piece, and the liquid outlet channels of several drainage holes are opened on the side wall of the shovel tooth piece for discharging cold liquid, and the condensate column is communicated with the corresponding flushing column.

[0018] Furthermore, a liquid-immersed cotton thread is fixedly provided inside the heat pipe. The shape of the liquid-immersed cotton thread is also N-shaped, which is the same as the shape of the heat pipe. The liquid-immersed cotton thread is divided into three parts: a conduction section, a water absorption section and an evaporation section.

[0019] Furthermore, the conduction section is the vertical end of the N-shape, corresponding to the condensation section of the heat pipe, the diameter of the conduction section is smaller than the diameter of the heat pipe, the water absorption section is arranged at the bottom end of the conduction section, and is a frustum shape, the evaporation section corresponds to the evaporation end of the heat pipe, the diameter is the same as the internal diameter of the heat pipe, and the evaporation section fills the evaporation end of the heat pipe.

[0020] The beneficial effects of the present invention are:

[0021] The present invention significantly improves the heat dissipation efficiency of high-power heating components through the collaborative design of a heat pipe-liquid cooling coupling structure and a three-stage heat dissipation mechanism. The cold liquid flow control component divides the coolant into a steady-state liquid replenishment flow and a pulsed jet flow. The upper steady-state flow continuously infiltrates the shovel blade array, achieving basic phase change heat dissipation by expanding the surface area.

[0022] The lower pulse flow impacts the reverse-inclined flushing column with a wave-like liquid flow, driving the piston structure to accurately inject the coolant into the outer wall of the condensation end of the n-type heat pipe, thereby enhancing the condensation efficiency of the heat pipe. Combined with the direct heat conduction path of the heat pipe evaporator section embedded in the inside of the heat dissipation base plate, a three-stage composite heat dissipation chain of "liquid cooling flushing-heat pipe phase change-surface area heat exchange" is formed.

DETAILED DESCRIPTION

[0033] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0034] like Figures 1-9 As shown, a radiator that uses heat pipes and a liquid cooling structure to achieve coupled heat dissipation includes: a radiator box 11, a skived-tooth radiator 2 sealed and fixed to the top of the radiator box 11, and the skived-tooth radiator 2 is composed of a heat dissipation base plate 21, a plurality of gantry-shaped skived-tooth blades 22 arranged vertically on the lower wall of the heat dissipation base plate 21, a cold liquid auxiliary spray component, and a cold liquid flow control component;

[0035] The heat dissipation base plate 21 is exposed outside the top plate of the radiator box 11 as the base surface for installing the heating element, and the skived blades 22 are vertically immersed in the inner cavity of the radiator box 11; the cold liquid flow control component is arranged at the liquid inlet end of the radiator box 11, and is configured to split the coolant into a dual-channel input of an upper steady-state liquid replenishment flow and a lower pulse jet flow;

[0036] The coolant spray kit includes:

[0037] A plurality of flushing columns 31 are arranged obliquely in the opposite direction of the main flow direction of the coolant, and a piston drive structure is provided therein;

[0038] Several n-type heat pipes 32, whose evaporation ends are embedded in the heat dissipation base plate 21, and whose condensation sections are connected to the liquid outlet ends of the flushing columns 31;

[0039] When the pulse jet forms a wavy liquid flow to impact the liquid column 31, the piston is driven to inject a quantitative amount of coolant into the outer wall of the condensation end of the heat pipe 32, thereby enhancing the condensation efficiency of the heat pipe through liquid cooling, and coordinating the surface area heat exchange of the skive blades 22 and the phase change heat transfer of the heat pipe to achieve three-stage composite heat dissipation. The inner cavity of the radiator box 11 forms a heat conduction path with the external heating element through the heat dissipation base plate 21.

[0040] A cold liquid inlet 15 is fixedly provided at the liquid inlet end of the outer wall of the radiator box 11, and a control pump 16 is connected to the cold liquid inlet 15. The liquid outlet end of the radiator box 11 is connected to the cold liquid outlet 14. The control pump 16 is controlled by the system and controls the flow rate of the cold liquid injected into the radiator box 11 as the temperature of the heating element installed on the heat dissipation base plate 21 changes.

[0041] The cold liquid flow control assembly includes a liquid control box 41, which is fixed to the liquid inlet end of the inner wall of the radiator box 11. The upper inner layer of the liquid control box 41 is a diversion chamber 47, in which a liquid infusion pipe 42 and a flushing pipe 43 are provided. Both the liquid infusion pipe 42 and the flushing pipe 43 are interconnected with the cold liquid inlet 15, and the liquid outlet end of the liquid infusion pipe 42 passes through the side wall of the liquid control box 41.

[0042] The lower layer inside the liquid control box 41 is a pressure wave-making chamber 44, which is connected to the flushing pipe 43. A rubber elastic bag is provided inside the pressure wave-making chamber 44. A wave-making plate 45 is rotatably provided on the outer wall of the liquid outlet end of the pressure wave-making chamber 44. An arc-shaped spring piece 46 is fixedly provided on the outer wall of the wave-making plate 45. The end of the spring piece 46 away from the wave-making plate 45 is fixedly connected to the outer wall of the diversion chamber 47.

[0043] The scraper blade 22 is divided into two parts. The side close to the heat dissipation base plate 21 is a solid plate 222 , and the side away from the heat dissipation base plate 21 is a gantry frame 221 . Some of the flushing columns 31 are exposed in the gantry frame 221 and partly embedded in the solid plate 222 .

[0044] A pressurizing piston 38 is slidingly provided inside the flushing column 31, a piston column 36 is fixedly provided below the pressurizing piston 38, and a water wave plate 37 is fixedly provided at the bottom end of the piston column 36. The water wave plate 37 is an inclined structure, forming an angle of 45° with the direction of the cold liquid flow, and a plurality of liquid inlet holes 35 are opened on the outer wall of the flushing column 31 in the middle part of the gantry frame 221.

[0045] The arc-shaped end of the heat pipe 32 is the evaporation end, and the vertical end is the condensation section. Condensate columns 33 are fixedly provided on the outside of the two condensation ends of the heat pipe 32. The condensate columns 33 are hollow frustum-shaped, and the outer wall of the condensate columns 33 is provided with several drainage holes 34.

[0046] The condensate column 33 is immersed in the shovel blade 22 , and outlet channels of a plurality of drain holes 34 are opened on the side wall of the shovel blade 22 for discharging cold liquid. The condensate column 33 is communicated with the corresponding flushing column 31 .

[0047] A liquid-soaked cotton thread 39 is fixedly installed inside the heat pipe 32. The shape of the liquid-soaked cotton thread 39 is also N-shaped, which is the same as the shape of the heat pipe 32. The liquid-soaked cotton thread 39 is divided into three parts: a conduction section 391, a water absorption section 392 and an evaporation section 393.

[0048] The conduction section 391 is the vertical end of the letter N, corresponding to the condensation section of the heat pipe 32. The diameter of the conduction section 391 is smaller than the diameter of the heat pipe 32. The water absorption section 392 is set at the bottom end of the conduction section 391 and is a frustum shape. The evaporation section 393 corresponds to the evaporation end of the heat pipe 32. The diameter is the same as the internal diameter of the heat pipe 32, and the evaporation section 393 fills the evaporation end of the heat pipe 32.

[0049] First, the heating element is fixedly mounted on the heat dissipation base plate 21. The control pump 16, the cold liquid outlet 14, and the cold liquid storage device are connected in series through pipes to form a circulation path. The cold liquid is pumped by the control pump 16 and injected into the radiator tank 11 through the cold liquid inlet 15. The cold liquid is then discharged from the cold liquid outlet 14 and finally flushed into the cold liquid storage device through the pipes.

[0050] The coolant is injected into the radiator tank 11 through the coolant inlet 15, first flowing into the liquid control box 41, and a portion flows out of the diversion chamber 47 through the liquid replenishing pipe 42 to replenish the coolant in the upper layer of the radiator tank 11, and the other portion flows into the pressure wave generating chamber 44 through the flushing pipe 43;

[0051] As the amount of coolant in the pressure wave chamber 44 increases, the rubber elastic bladder gradually expands. When the pressure in the rubber elastic bladder exceeds the resistance of the spring 46 to the wave-making plate 45, the wave-making plate 45 rotates and opens under the impact of the coolant pressure. At this time, the opening of the wave-making plate 45 causes the coolant in the lower layer of the radiator tank 11 to fluctuate, causing the fluctuating coolant to impact the plurality of water wave plates 37. The impact of the water wave plates 37 pushes the piston rod 36 and the pressurizing piston 38 to slide upward, thereby squeezing the coolant that has seeped in through the liquid inlet 35 upward.

[0052] The cold liquid pushed upward by the pressurizing piston 38 flows into the condensate column 33, condensing the condensation section of the heat pipe 32. The cold liquid is then discharged from the drain hole 34. Under the gravity of the water wave plate 37, the pressurizing piston 38 is automatically reset.

[0053] The heating element transfers heat to the heat dissipation base plate 21. The multiple heat pipes 32 in the heat dissipation base plate 21 evaporate at the evaporation end. The hot air flows along the heat pipes 32 to the condensation section and is instantly cooled by the cold liquid in the condensation liquid column 33, causing condensation. The condensed water droplets are deposited at the bottom of the condensation section and gradually absorbed by the water absorption section 392. The soaked cotton thread 39 has strong water conductivity. The condensed water droplets gradually penetrate into the conduction section 391 and the evaporation section 393 in turn. The evaporation section 393 is in close contact with the evaporation end of the heat pipe 32. The cold water cools the evaporation end, and the cycle circulates in sequence, resulting in faster cooling.

[0054] The control pump 16 can control the flow rate of the cold liquid according to the actual temperature of the heating element, thereby controlling the frequency at which the pressurizing piston 38 delivers the cold liquid into the condensate column 33 .

[0055] Radiator box 11 and skived radiator 2 coupling structure:

[0056] The heat dissipation base plate 21 is exposed as the base surface for installing the heating element, and directly transfers heat to the inner cavity of the box through the heat conduction path to reduce thermal resistance;

[0057] The vertical immersion design of the gantry-shaped shovel blades 22 increases the liquid cooling contact area, combining surface area heat exchange with heat pipe phase change heat transfer to form a dual heat dissipation path.

[0058] Dynamic adjustment mechanism of cold liquid flow control components:

[0059] The control pump 16 adjusts the flow rate of the cold liquid in real time according to the temperature of the heating element to avoid energy waste;

[0060] The diversion is a dual-channel design of steady-state fluid replenishment flow and pulse jet flow, taking into account both basic heat dissipation requirements and transient thermal shock response capabilities.

[0061] Liquid control box 41 layered diversion structure:

[0062] The upper diversion chamber 47 provides continuous steady-state liquid flow through the liquid infusion pipe 42 to maintain basic heat exchange;

[0063] The lower pressure wave-making chamber 44 utilizes a rubber elastic bag and a wave-making plate 45 to generate a pulsed water flow, thereby enhancing local turbulent heat exchange.

[0064] Flushing column 31 piston drive and tilt layout:

[0065] The reverse tilt layout makes the water flow impact direction match the piston movement direction, improving the kinetic energy conversion efficiency;

[0066] The pressurizing piston 38 is driven by the pulsed water flow to quantitatively inject cold liquid into the condensing end of the heat pipe, accurately controlling the timing of liquid cooling enhancement.

[0067] The n-type heat pipe 32 and the condensate column 33 are designed in coordination:

[0068] The evaporation end is embedded in the heat dissipation base plate 21 to achieve rapid thermal response, and the condensation section expands the heat dissipation area through the condensate column 33;

[0069] The drain holes 34 spray the cooling liquid toward the sidewalls of the scraper blades 22 in a directional manner, thereby forming a local liquid film to enhance heat exchange.

[0070] Optimization of 39 segments of soaked cotton thread:

[0071] The reduced diameter design of the conduction section 391 reduces the resistance to the return of the cold liquid, and the frustum shape of the water absorption section 392 enhances the capillary suction force;

[0072] The evaporation section 393 fills the evaporation end of the heat pipe to ensure that the working fluid is fully vaporized and improve the phase change heat transfer efficiency.

[0073] Summary of work steps:

[0074] Cooling liquid input and diversion: The cooling liquid enters the liquid control box 41 through the cooling liquid inlet 15, the upper steady-state liquid replenishment flow continuously replenishes the basic liquid flow through the liquid replenishment pipe 42, and the lower pulse jet flow enters the pressure wave chamber 44 to generate a wavy liquid flow.

[0075] Pulse-driven piston injection: The wavy liquid flow impacts the inclined water wave plate 37, pushing the pressurizing piston 38 to slide along the liquid column 31, and injecting a certain amount of cold liquid into the outer wall of the condensation end of the heat pipe 32 through the condensation liquid column 33.

[0076] Liquid cooling enhances heat pipe condensation: The injected cold liquid forms a liquid film on the outer wall of the condensate column 33 and is sprayed to the side wall of the shovel blade 22 through the drainage hole 34, while reducing the temperature of the heat pipe condensation section and enhancing the phase change heat transfer efficiency.

[0077] Three-level composite heat dissipation synergy:

[0078] Heat exchange on the surface area of ​​the skiving blade 22: the solid plate 222 and the gantry frame 221 structure expand the liquid cooling contact surface;

[0079] Heat pipe phase change heat transfer: n-type heat pipe 32 achieves rapid thermal response through liquid-impregnated cotton thread 39;

[0080] Liquid cooling enhancement: Pulse liquid injection and steady-state liquid replenishment work together to maintain efficient heat dissipation at the condensing end.

[0081] Heat flow extraction and circulation: The heat of the heating element is transferred to the inner cavity of the radiator box 11 through the heat dissipation base plate 21, and is extracted through the dual paths of the skived blades 22 and the heat pipe 32, and finally the heated liquid is discharged from the cold liquid outlet 14, completing the heat dissipation cycle.

The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
