[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0032] The following describes an embodiment of the utility model based on its overall structure.

[0033] A water-cooling heat dissipation mechanism for a vehicle-mounted power supply, such as Figure 1 - Figure 6 As shown, it includes a vehicle power supply body 1, a battery 2 and a heat sink 3. Multiple groups of batteries and the heat sink 3 are installed inside the vehicle power supply body 1, and the heat sink 3 is surrounded and connected to the outer wall of the multiple groups of batteries 2. The heat sink 3 absorbs the heat generated by the battery 2;

[0034] The inner wall of the vehicle power supply body 1 is provided with multiple groups of mounting grooves which are respectively fixedly connected to multiple groups of batteries 2, so that the batteries 2 are mounted inside the vehicle power supply body 1 to prevent the batteries 2 from squeezing the heat sink 3. The water inlet of the heat sink 3 is installed with a water inlet pipe 13, and the water outlet of the heat sink 3 is installed with a water outlet pipe 14. The vehicle battery body 1 is provided with multiple groups of reserved grooves 4, and the multiple groups of reserved grooves 4 are all connected to the heat sink 3. The upper ends of the multiple groups of reserved grooves 4 are provided with air outlet grooves 5, and the inner walls of the multiple groups of air outlet grooves 5 are installed with first filter plates 6, and the heat absorbed by the heat sink 3 is discharged from the air outlet grooves 5.

[0035] See also Figure 3 - Figure 5 The cross-section of the heat sink 3 is a multi-section "S"-shaped arrangement, and the width of one end of the heat sink 3 where the water inlet pipe 13 is installed is greater than the width of the other ends of the heat sink 3. The heat sink 3 fits multiple groups of batteries 2, and the thickness of the end of the heat sink 3 where the water inlet pipe 13 is installed is greater than the other ends of the heat sink 3, so that the coolant enters the small channel from the large channel, accelerating the flow of the coolant.

[0036] See also Figure 3 - Figure 6 A driving shaft 11 is installed through one end of a water inlet pipe 13 installed on the heat sink 3, and a plurality of driving plates 12 are installed on the outer wall of the driving shaft 11. The coolant passes through the driving plate 12 to drive the driving plate 12 to move, thereby driving the driving shaft 11 to rotate.

[0037] See also Figure 6 The outer walls of the multiple sets of driving plates 12 are all arranged in an arc shape and tilted, and the driving plates 12 are made of a lighter material, which increases the force on the driving plates 12 and improves the rotation effect of the driving plates 12.

[0038] See also Figure 1 - Figure 2 Multiple groups of air inlets 7 are provided on both sides of the vehicle power supply body 1, and the multiple groups of air inlets 7 are respectively connected to the multiple groups of reserved slots 4. The airflow enters the reserved slots 4 from the air inlets 7, drives the heat of the heat sink 3, and flows out from the air outlet slots 5.

[0039] See also Figure 2 - Figure 4 , the inner walls of multiple groups of air outlet slots 4 are all installed with second filter plates 8, and the outer walls of one side of multiple groups of second filter plates 8 are movably installed with connecting shafts 9, and the multiple groups of connecting shafts 9 are connected by synchronous belts, and the two groups of connecting shafts 9 are respectively connected to the two ends of the driving shaft 11 through synchronous belts. The driving shaft 11 rotates, driving the two groups of connecting shafts 9 to rotate, thereby driving the multiple groups of connecting shafts 9 to rotate.

[0040] See also Figure 1 - Figure 5 The outer walls of the multiple sets of linkage shafts 9 are all sleeved with fans 10, one end of the water inlet pipe 13 and one end of the water outlet pipe 14 are both externally connected to the water outlet and water inlet of the water circulation pump. The multiple sets of linkage shafts 9 rotate, driving the fans 10 to rotate, and the water circulation pump is started, so that the coolant circulates.

[0041] The working principle of the utility model is as follows: when the vehicle-mounted power source body 1 is dissipating heat, the water circulation pump is started to pump the coolant into the water inlet pipe 13, one end of the water inlet pipe 13 is connected to the water inlet of the heat sink 3, so that the coolant enters the heat sink 3, and the heat sink 3 is arranged around and fits the outer wall of the multiple battery groups 2. The coolant flows inside the heat sink 3 to absorb the heat of the multiple battery groups 2, and the absorbed heat is discharged outward through the air outlet slot 5 when passing through the reserved slot 4, thereby improving the use effect of the heat sink 3;

[0042] After the coolant enters the heat sink 3, it flows quickly inside the heat sink 3. The thickness of the end of the heat sink 3 where the water inlet pipe 13 is installed is greater than the other ends of the heat sink 3, so that the coolant enters the small channel from the large channel, which accelerates the flow of the coolant. The drive shaft 11 is arranged at the connecting end of the large channel and the small channel, so the coolant impacts the multiple drive plates 12, causing the multiple drive plates 12 to move, driving the drive shaft 11 to rotate.

[0043] When the driving shaft 11 rotates, because both ends of the driving shaft 11 are respectively connected to the two sets of linkage shafts 9 through synchronous belts, the two sets of linkage shafts 9 rotate synchronously, and the multiple sets of linkage shafts 9 are connected through synchronous belts, so the multiple sets of linkage shafts 9 rotate, thereby driving the multiple sets of fans 10 to rotate, so that the multiple sets of air inlets 7 generate suction to the outside;

[0044] The airflow enters the reserved slot 4 through the air inlet 7, and the dust particles mixed in the airflow are blocked by the second filter plate 8, and the shaking caused by the rotation of the linkage shaft 9 causes the dust particles adsorbed on the surface of the second filter plate 8 to fall off, thereby avoiding blockage of the air inlet 7;

[0045] The airflow enters the reserved slot 4 from the multiple groups of air inlets 7 and is discharged from the air outlet slot 5. While the airflow flows, the heat conduction of the heat sink 3 is accelerated, so that the heat is discharged from the air outlet slot 5, further improving the heat dissipation effect of the heat sink 3, thereby improving the use effect of the heat sink 3, and further improving the cooling and heat dissipation effect of the vehicle-mounted power supply body 1. After the coolant passes through the heat sink 3, it flows back to the water circulation pump from the water outlet pipe 14 at the other end of the heat sink 3.

[0046] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
