Specific embodiment
In order to which the purpose of the present invention, technical solution and advantage is more clearly understood, below in conjunction with drawings and examples,
The present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used for explaining this hair
It is bright, it is not intended to limit the present invention.
As shown in Figure 1, the present invention end cover type cooled plate include a mainboard 1, the mainboard 1 be square or cuboid,
The mainboard 1 has the first surface 101 that is oppositely arranged and second surface 102, in the present embodiment, the first surface 101 and the
Two surfaces 102 are two relatively parallel planes, and are formed by the height and length or width of the mainboard 1.
In order to reduce the amount of machining in process, to improve production efficiency and to reduce cost, squeezed on mainboard 1
The molded multiple through holes having through first surface 101 and second surface 102, the plurality of through hole are used to circulate for current, use
When the through hole on mainboard 1 need to only be penetrated through successively and both ends seal, and it is of the prior art up and down knockdown water cooling
Plate can increase the difficulty of sealing and have the hidden danger of leak, it is necessary to the sealing of large area, and cooled plate of the invention is profile extrusion
Shaping, solve the problems, such as it is of the prior art this, the area that seals of end cover type cooled plate of the invention needs is small, and sealing is simple
And do not have the hidden danger of leak.
The cooled plate further includes to seal 2 He of the first end cap for the port that multiple through holes are located on first surface 101
For sealing the second end cap 3 of the port that multiple through holes are located on second surface 102.It, can be in order to enhance sealing intensity
First sealing ring 4 between one end cap 2 and multiple through holes is set, the second sealing ring is set between the second end cap 3 and multiple through holes
5, wherein, the first sealing ring 4 and the second sealing ring 5 are fluorubber product.In order to reduce sealing area as much as possible, first
The total length of 4 and second sealing ring 5 of sealing ring is small as much as possible.
Further, in order to enhance the ability to bear of cooled plate, 2 and second end cap 3 of the first end cap passes through spiral shell respectively
Nail 6 is locked on mainboard 1.Specifically, threaded hole, screw 6 are correspondingly opened up on the first end cap 2, the second end cap 3 and mainboard 1
The tight fit so as to fulfill the first end cap 2 and the second end cap 3 and mainboard 1 is fitted close with threaded hole.
Further, it is circular hole mostly to solve perforate of the prior art, causes to dissipate since heat dissipation area is limited
The problem of thermal energy power is limited, the multiple through holes opened up in end cover type cooled plate of the invention penetrate through the S so as to fulfill current successively
Type flows, and multiple through holes include the first circular hole 103 and the second circular hole 104 and positioned at the first circular hole 103 and the second circular hole
At least one throughbore between 104.Specifically, throughbore can be included main aperture and extend at least along main aperture periphery
One elongated hole.It is understood that set the first circular hole 103 and the second circular hole 104 purpose be to provide for water inlet and
Water outlet, circular hole are conducive to the installation of inlet channel and outlet conduit, and are set between the first circular hole 103 and the second circular hole 104
The purpose for putting at least one throughbore is in order to increase the contact area of current and cooled plate, so as to increase current and heat source
Contact area, to improve the radiating efficiency of cooled plate.Wherein, the quantity of throughbore is decided according to the actual requirements, such as basis
The quantity of the real area selection throughbore of heat source, when the area of heat source is larger, opens up more throughbore.In this reality
It applies in example, multiple through holes are in one line, in order to which smooth in water flow flows and reduces the total volume of mainboard.It is understood that
In other embodiments, multiple through holes can also be just arranged at intervals, and need to only ensure that throughbore is located at the first circular hole 103 and the
Between two circular holes 104.
