Description

BACKGROUND OF THE INVENTION 1. Field of the invention: The present invention relates to the field of liquid cooling device technology, in particular an all-in-one liquid cooler for cooling and dissipating heat from a processor. 2. Description of the state of the art: Liquid coolers used in computers and servers today are typically split coolers, consisting of a separate liquid cooling radiator, a cooling plate, and a liquid pump connected by multiple liquid lines to form a closed loop system. However, the split type is bulky and inconvenient to install. To address this, the inventor of this case proposed a variety of all-in-one liquid cooler designs. The all-in-one liquid cooler features a liquid pump inside a liquid cooling radiator and a cooling plate at the bottom. The cooling plate can be installed on a processor to function as a liquid-cooled processor. However, the conventional design of liquid cooling radiators can result in uneven distribution of the coolant through the individual fluid lines, leading to inconsistent heat dissipation efficiency. If the coolant flow rate is higher in some fluid lines and lower in others, heat cannot be effectively dissipated, resulting in reduced heat dissipation efficiency in certain areas. This uneven circulation can lead to an unbalanced temperature distribution within the processor, negatively impacting its stability and performance. If, however, the fluid flow rate is too high, the total volume of the cooler can be increased, but the fluid does not have sufficient residence time to effectively absorb heat as it flows through the heat dissipation tubes and the cooling plate. Consequently, the heat cannot be completely transferred to the coolant, resulting in insufficient overall heat dissipation. Ideally, an appropriate flow rate should be maintained so that the fluid has enough time to absorb the heat, but the flow rate is not so slow as to impair the coolant's circulation efficiency. Therefore, the question of how to improve upon the aforementioned shortcomings of the prior art is the subject of the present invention, which aims to actively overcome these deficiencies. SUMMARY OF THE INVENTION The main objective of the present invention is to provide an all-in-one liquid cooler to solve the problems of uneven flow rate and excessive flow rate of the liquid in each heat dissipation tube of the conventional liquid cooler, so that the liquid can flow uniformly through each heat dissipation tube and completely dissipate the heat. Another objective of the present invention is to provide an all-in-one liquid cooler to solve the problem of the hot liquid exiting the cooling plate being thermally transferred to the adjacent cold liquid, thereby ensuring that the cold liquid flows into the cooling plate at a low temperature. To achieve the aforementioned objectives, the present invention proposes an all-in-one liquid cooler, the preferred technical solution of which comprises a liquid cooling radiator and a cooling plate. The liquid cooling radiator has a first liquid reservoir, a second liquid reservoir, and a heat dissipation tube assembly. The heat dissipation tube assembly has a plurality of first-row tubes, second-row tubes, and heat dissipation fins. The first-row and second-row tubes are flat metal tubes, both ends of which are connected to the first and second liquid reservoirs, respectively. The heat dissipation fins are arranged outside the first-row and second-row tubes, respectively. The top of the cooling plate is connected to the outside of the bottom wall of the first liquid reservoir, and the underside of the cooling plate is designed to adhere to the surface of a processor. The first liquid reservoir has a first reservoir body and a first reservoir lid. The upper end of the first vessel body is concave to form a first chamber, and the interior of the first chamber is divided into a cold liquid chamber and a hot liquid chamber by a heat-resistant structure. The bottoms of the cold liquid chamber and the hot liquid chamber are each connected to the interior of the cooling plate via a cold liquid inlet and a hot liquid inlet, respectively. The first vessel lid covers the upper end of the first vessel body, and the upper wall of the first vessel lid is reinforced with a variety of first rows. The tubes are provided with inlet holes that connect to the cold liquid chamber and the hot liquid chamber. The lower ends of the first row of tubes and the second row of tubes are each inserted into the inlet holes of the first row of tubes. A flow divider orifice is provided in the cold liquid chamber, featuring a plurality of through-holes connecting its two sides. The flow divider orifice allows the liquid flowing from the first row of tubes into the cold liquid chamber to be distributed through the plurality of through-holes and then flow through the cold liquid opening into the interior of the cooling plate.
