Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1-2, a heat sink electrode comprises a main body section 11 in a circular tube shape, an electrode mounting guide section 12 integrally arranged at one end of the main body section 11, and a water tap mounting guide section 13 integrally arranged at the other end of the main body section 11, wherein a drainage hole 14 is arranged on a part of the side wall of the main body section 11 close to the electrode mounting guide section 12.
The radiator electrode 1 is made of high-strength metal with a bipolar anti-corrosion protection function, the base material is 316L stainless steel, the base material has an anti-corrosion effect on flowing non-neutral deionized water, the influence on water quality caused by the generation of floating rust is prevented, meanwhile, the surface of the material is provided with a passivation film with a conductive function, the anti-corrosion capability of the radiator electrode 1 is further enhanced while the through-flow (current) of electronic components borne by the radiator is not influenced, and the service life is prolonged.
In addition, in order to adapt to the application environment and further improve the performance of the radiator electrode 1, the material can also adopt metal with higher specification, such as 316-Ti and the like, and the surface of the material can also be plated with a metal coating with stronger corrosion resistance, such as nickel, zinc and the like.
In order to improve the mounting efficiency of the heat sink electrode 1, the electrode mounting guide section 12 has a tapered structure, and the outer diameter of the free end thereof is smaller than that of the main body section 11.
Specifically, the taper of the electrode mounting guide section 12 is 30-60 degrees, and the length is 1/10-1/6 of the length of the whole radiator electrode 1.
The electrode installation guide section 12 has a guide effect in the installation process, so that the radiator electrode 1 can be quickly and effectively positioned, and the risk of non-coaxial arrangement of the radiator electrode 1 and the electrode connecting section 22 is reduced.
Because the radiator electrode 1 is installed firstly and then the radiator water joint 3 is installed in the installation process, in order to improve the installation efficiency of the radiator water joint 3, the water joint installation guide section 13 is of a conical structure, and the outer diameter of the free end of the water joint installation guide section is smaller than that of the main body section 11.
Specifically, the taper of the water joint installation guide section 13 is 45 degrees, which can avoid the influence on the installation caused by the cross interference between the water joint 3 of the radiator and the electrode 1 of the radiator when the water joint is installed.
In order to guide the cooling water accumulated outside the radiator electrode 1, the two drainage holes 14 are axially symmetrically distributed relative to the main body section 11.
The drainage holes 14 can be circular or elliptical through holes, and the area of the drainage holes is 1/10-1/6 of the flow area of the radiator electrode 1.
Secondly, as shown in fig. 3, the invention also provides a radiator, which comprises a radiator body 2 with a water inlet and a water outlet, wherein the radiator electrode 1 is respectively pressed in the water inlet and the water outlet, and the radiator electrode 1 is externally sleeved with a radiator water joint 3 which is in threaded fit with the water outlet and the water inlet.
In order to realize the matched installation of the water inlet and the water outlet with the radiator electrode 1 and the radiator water joint 3, the water inlet and the water outlet sequentially comprise a water joint connecting section 21, an electrode connecting section 22 and a bottom hole section 23 from outside to inside, and the inner diameters of the water joint connecting section 21, the electrode connecting section 22 and the bottom hole section 23 are sequentially reduced.
In order to realize the installation of the heat sink electrode 1, the electrode installation guide section 12 is installed in the electrode connection section 22, and the main body section 11 and the electrode connection section 22 are in interference fit.
When the radiator electrode 1 is installed, the electrode installation guide section 12 of the radiator electrode 1 is inwards pressed into the electrode connecting section 22, meanwhile, part of the main body section 11 at the end where the electrode installation guide section 12 is located is also installed into the electrode connecting section 22, and the main body section 11 is in interference fit with the electrode connecting section 22, so that the installation stability of the radiator electrode 1 is ensured.
In addition, because the inner diameter of the bottom hole section 23 is smaller than that of the electrode connecting section 22, and the two sections are connected through a plane, the structure has a secondary limiting function on the installed radiator electrode 1.
Specifically, the basic value of the outer diameter of the main body section 11 is consistent with the inner diameter of the electrode connecting section 22, and the tolerance is controlled to be 15-80 μm, so that the stability of the fit between the two is ensured. The tolerance here is a positive tolerance, i.e. the outer diameter of the body section 11 is greater than the inner diameter of the electrode connecting section 22.
In order to realize the installation of the radiator water joint 3, the radiator water joint 3 is installed in the water joint connecting section 21 through threads, and a gap is reserved between the inner wall of the radiator water joint 3 and the outer wall of the radiator electrode 1.
Preferably, a metric thread or a non-sealing type control thread is arranged on the inner wall of the water joint connection section 21, and the radiator water joint 3 is installed in the water joint connection section 21 through thread fit.
The installation of the water joint of the radiator can be simplified by selecting the metric thread or the non-sealed type pipe thread.
Specifically, the radiator water joint 3 is made of high-strength engineering plastics.
Taking a water inlet as an example, after the radiator electrode 1 and the radiator water joint 3 are installed, a small gap is left between the radiator electrode 1 and the radiator water joint 3, cooling water directly enters the radiator through the radiator electrode 1 mainly via the radiator water joint 3, a small amount of cooling water possibly flows into the water inlet through a fit gap between the radiator water joint 3 and the radiator electrode 1, if the part of cooling water is accumulated in the water inlet for a long time, dead water is easily formed to corrode a base material of the radiator, and in order to realize the collection of the part of cooling water, the water joint connecting section 21 positioned on the inner side of the radiator water joint 3 forms a water collecting groove 24.
In order to facilitate the drainage of the cooling water accumulated in the collecting tank, the inner end surface of the water joint connecting section 21 is an inclined surface 25, and the inner side edge of the inclined surface 25 is intersected with the drainage hole 14 or the edge of the drainage hole 14 facing the electrode mounting guide section 12 is tangent.
The positional relationship between the drainage holes 14 and the inner side edge of the inclined plane 25 can ensure that the cooling water in the water collecting tank 24 completely enters the inside of the radiator.
Preferably, in order to ensure the flow efficiency of the cooling water in the water collecting tank 24 entering the radiator, the exposed area of the drainage hole 14 at the water collecting tank 24 is much larger than the area of the part shielded by the electrode connecting section 22.
A small amount of water entering the water inlet will gather in the water collection tank 24 due to the action of gravity, then enter the radiator electrode 1 through the drainage hole 14, and then enter the inside of the radiator. Meanwhile, when the flow rate of the cooling water directly passing through the radiator electrode 1 from the radiator water joint 3 reaches a certain value, a siphon effect is formed on the cooling water stored in the water collecting tank 24, the flow of the cooling water is accelerated, and the risk of corrosion to the radiator is reduced.
At the water outlet of the radiator, cooling water flows out from the inside of the radiator through the radiator electrode and enters the radiator water joint 3 to continuously flow out, because the through-flow diameter of the radiator electrode 1 and the through-flow diameter of the radiator water joint 3 have a difference value, the cooling water passes through the junction of the electrode connecting section 22 and the water joint connecting section 21 and has the condition of variable diameter diffusion, a small amount of cooling water collides with the radiator water joint 3 and then flows into the water collecting tank 24 under the action of gravity, the cooling water stored in the water collecting tank 24 can be introduced into the radiator electrode 1 as the water inlet due to the arrangement of the drainage holes 14 and then is discharged through the radiator water joint 3 again, thereby avoiding the formation of dead water in the water collecting tank 24 and preventing the corrosion of the radiator.
In order to ensure the installation tightness of the radiator water joint 3, sealing elements 4 positioned between the radiator body 2 and the radiator water joint 3 are installed on the outer end faces of the water inlet and the water outlet.
The sealing element 4 is arranged on the outer end faces of the water inlet and the water outlet, so that the limitation of type selection of the radiator water pipe and the radiator water joint 3 is reduced, the disassembly and the maintenance in the use process are facilitated, and the universality is high.
Preferably, the sealing element 4 can be an annular sealing gasket or an O-ring.
In the assembling process of the radiator of the embodiment, the electrode installation guide section 12 and the electrode connecting section 22 are in preliminary positioning fit, then the main body section 11 is installed in a compression joint mode, the radiator is installed to the position where the drainage hole 14 is tangent to or slightly intersected with the outer port of the electrode connecting section 22, at the moment, the outer end face of the radiator electrode 1, which is lower than the water outlet or the water inlet, is flush or slightly lower, and the installation of the radiator electrode 1 is completed. Next, the radiator water joint 3 is installed, the process can form primary positioning through the water joint installation guide section 13 and the water joint connection section 21, the risk of local damage caused by cross interference is reduced, then the installation connection is carried out on the radiator water joint 3 through threads, and the installation of the radiator water joint 3 can be completed by adopting the sealing piece 4 to carry out sealing matching with the outer end face of the water inlet or the water outlet, and the radiator water joint 3 and the radiator electrode 1 form cross clearance fit at the moment.
The radiator electrode 1 adopts a compression joint installation form, has a simple structure, reduces the difficulty of design and model selection, adopts a limiting and guiding structure in the application structure in the installation matching with the water inlet and the water outlet of the radiator and the water connector 3 of the radiator, improves the installation operability, reduces a passive sealing structure, reduces the operation leakage risk, and has stable and reliable integral operation and strong economical efficiency.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
