[0039] The following is a detailed description of the embodiments and the attached Figure 1-8 The utility model scheme is further elaborated and illustrated.

[0040] Utility Model Embodiment 1:

[0041] The utility model provides a multi-channel water-cooled radiator, which can simultaneously support multiple groups of water pumps and water inlet and outlet nozzles that cooperate with the water pumps to guide the coolant to circulate in the water-cooled radiator, thereby achieving the purpose of synergistic efficiency. Figure 1-4As shown, the multi-channel water-cooled radiator includes: a water pump assembly 1, a water-cooled body 2, and a water guide assembly 3 forming a circulating water path between the water pump assembly 1 and the water-cooled body 2.

The water guide component 3 is respectively provided with water suction holes 31 at the central projection positions of the two impellers 13. The coolant flows inside the water guide component 3 and is guided from bottom to top from the heat exchange chamber to the water outlet nozzle 53 under the water suction action of the water pump, thereby forming a water outlet channel connecting the heat exchange chamber, the water suction hole 31 to the water outlet nozzle 5. A water guide hole 32 is opened outside the water suction area of ​​the impeller 13 of the water guide component 3 or a water guide gap 33 is formed between the water guide component 3 and the upper and lower cavity shells outside the water suction area of ​​the water pump. The water guide hole 32 and the water guide gap 33 are connected to the water inlet nozzle 4 and are located outside the water suction area of ​​the water pump, thereby forming a water inlet channel that is relatively independent of the water outlet channel and connects the water inlet nozzle 4, the water guide hole 32 or the water guide gap 33 to the heat exchange chamber. Compared with the traditional single-channel radiator, the multi-channel water-cooled radiator formed in this way has higher heat dissipation efficiency and smaller volume; and the internal structure is simple, the water outlet channel and the water inlet channel are relatively independent and the path is unobstructed, the water flow resistance is small and the flow rate is fast, and it can support multiple groups of water pumps and water inlet and outlet nozzles matched with the water pumps to guide the coolant to circulate in the water-cooled radiator, and realize rapid heat exchange between the cold and hot water circuits. Of course, other embodiments can configure the number of channels according to the heat dissipation needs. Optionally, this water-cooled radiator can be provided with 3-5 water pumps and water inlet and outlet nozzles matched with the water pumps.

[0042] like Figure 1-4As shown, the water guide assembly 3 includes an upper cavity water guide assembly and a lower cavity water guide assembly sealed and assembled with the upper cavity water guide assembly. The upper cavity water guide assembly is fixedly mounted below the pump body assembly 1 and has a water drawing chamber. The water drawing chamber is connected with the heat exchange chamber and the water outlet nozzle 5. The water drawing chamber is located on the flow path of the water outlet channel. As one of the circulation pools of the coolant, it can coordinate the water drawing effect of the impeller and buffer the flow of liquid in the system. In this embodiment, the upper cavity water guide assembly includes an upper cavity water guide cover 3a and an upper cavity sealing cover 3b, the upper cavity water guide cover 3a is fixedly connected to the upper cavity sealing cover 3b and a water drawing chamber is formed inside, the upper cavity water guide cover 3a is respectively provided with a guide part corresponding to the two impellers 13, and a spiral guide structure 34 is provided on the side of the guide part away from the pump body assembly, and the spiral guide structure can be used to gather water flow and supply water to the impeller, and the upper cavity sealing cover 3b is sealed and assembled with the guide part of the upper cavity water guide cover 3a to form independent water channels, namely, a water inlet channel and a water outlet channel inside and outside the two, respectively, wherein the water outlet channel is located inside the two, and the water inlet channel is located outside the two, and a water flow grid 35 whose upper end surface abuts the upper cavity water guide cover 3a is also provided in the middle of the upper cavity sealing cover, and the water inlet water path flowing through the water inlet channel can form an interactive flow through the water flow grid 35, thereby coordinating the flow of coolant between different channels, and to a certain extent realizing the control of the coolant flow in different channels.

[0044] like Figure 1-4As shown, the heat absorption component is connected to the lower cavity shell 21 and a heat exchange chamber is formed inside the heat absorption component, including a heat conductive base 22 and a heat dissipation fin group 23. The heat dissipation fin group 23 is fixedly installed in a heat exchange groove recessed in the middle of the heat conductive base 22, and the heat exchange groove corresponds to the periphery of the heat dissipation fin group 23 to form a water collection channel 24 for connecting the water inlet channel. The lower cavity water guide component also includes a lower cavity water guide plate 3c correspondingly arranged flat on the heat dissipation fin 23, and a strip through hole 36 is opened in the middle of the lower cavity water guide plate 3c, and the strip through hole 36 extends in a direction perpendicular to the heat dissipation fin group 23. After the coolant enters the heat exchange chamber through the water inlet channel, the coolant fills the water collection channel 24 and flows into the heat dissipation fin group 23 under the suction of the water pump, fully contacts the heat conductive base 22, and the heat is transferred from the heat source to the coolant. After absorbing the heat, the coolant flows upward under the water pump water pumping action, passes through the strip through hole 36 of the lower cavity water guide plate 3c and enters the water outlet channel. In order to rationalize the structure, the strip-shaped through hole 36 of the lower cavity water guide plate 3c in this embodiment passes through the vertical projection of the center of the two impellers 13 on the lower cavity water guide plate 3c, so that the water pump after the coolant flows through the strip-shaped through hole has a stronger water pumping force, a smaller flow resistance, and a faster flow rate, which is conducive to simplifying the water flow path and improving the heat dissipation efficiency. Of course, the number, position and length of the through holes can be selected according to needs in other embodiments.
