The cooling body 10 is provided with a cold inlet channel 11 and a cold outlet channel 12 on both sides along the length direction of the plate surface. The cold inlet channel 11 and the cold outlet channel 12 are respectively provided with a cold inlet 111 and a cold outlet 121 for respectively introducing a cooling medium and flowing out the cooling medium, wherein the cold inlet 111 and the cold outlet 121 can be arranged on the same side of the left side and the right side as required, or can be arranged in opposite directions as required, so as to realize cold inlet and cold outlet of the cooling plate in the same direction or different directions; the cooling medium is generally implemented as cooling water, and may also be implemented as other refrigerants or refrigeration gases as long as the heat of the cooled object can be taken away by the circulation flow of the cold. The cooling body 10 is further provided with a plurality of cooling channels 13 in parallel along the length direction, and the cooling channels 13 are communicated with the cooling inlet channel 11 and the cooling outlet channel 12, so that the cooling medium circulates in the cooling channels 13 to cool the object on the surface of the cooling plate, for example, to cool the laser in operation.
It is worth mentioning that the cooling channels 13 are generally implemented in a curved shape, such as a zigzag shape, in order to effectively remove heat while increasing the cooling area as much as possible. Other shapes, such as circular or polygonal, will also occur to those skilled in the art depending on the particular cooling needs. The specific shape of the cooling channel 13 is not limited in detail herein, and is within the scope of the present invention.
The sealing plate 20 is covered on the cooling body 10 to seal the cooling passage 13.
As a preferred embodiment of the present invention, the cooling body 10, the cold inlet channel 11, the cold outlet channel 12 and the cooling channel 13 are integrally formed, so that the structural stability of the cooling body 10 can be effectively increased, and the cooling body 10 can be conveniently manufactured.
In a possible embodiment, several cooling channels 13 are disposed on the top or bottom surface of the cooling body 10, such as digging or chiseling the cooling channels 13 with a predetermined track on the surface of the cooling body 10, and the sealing plate 20 is correspondingly covered on the top or bottom surface of the cooling body 10, so as to effectively solve the problems of dust prevention and condensation. The cooling channel 13 is manufactured by processing the top surface or the bottom surface of the cooling body 10, which is determined by the processing depth of the cooling channel 13, so that the molding of the cooling body 10 is facilitated, and the working time can be saved. Depending on this distance, a corresponding cooling rate can be generated at the top or bottom side of the cooling plate by the cooling medium in the cooling channel 13.
Thus, according to the actual need, the utility model provides in one particular embodiment: the distances between the cooling channel 13 and the top surface of the cooling plate and the bottom surface of the cooling plate are equal, so that the same cooling speed is provided at the top surface and the bottom surface by the cooling medium in the cooling channel 13. In a particular application, cooled targets having the same heat generation may be placed on the top and bottom surfaces, thereby cooling two identical targets simultaneously.
In addition, the present invention provides, according to actual needs, in another embodiment: the cooling channel 13 and the top surface of the cooling plate and the bottom surface of the cooling plate have a predetermined thickness difference, for example, the distance between the cooling channel 13 and the top surface is greater than the distance between the cooling channel 13 and the bottom surface, that is, the cooling channel 13 can provide more cooling capacity at the bottom surface. Therefore, in a specific application, a target object with larger heat generation quantity can be placed on the bottom surface, and a target object with smaller heat generation quantity is placed on the top surface, so that the cooling plate provided by the utility model can be used for cooling two different target objects simultaneously, and has a wider application range.
It is to be noted how, according to the needs of some special cases, for example, how cooling energy with the same cooling rate can be provided on the top surface and the bottom surface by simply providing the cooling channels 13 on a thicker plate, for example, how the inherent structural stability of the cooling body 10 can be maintained as much as possible when providing the cooling channels 13. Therefore, the utility model also provides a possible implementation: two adjacent cooling passages 13 of the plurality of cooling passages 13 are respectively disposed on the top surface and the bottom surface of the cooling main body 10, that is, the cooling main body 10 is implemented as a sandwich plate, and the cooling passages 13 are sequentially disposed on the top surface and the bottom surface in a staggered manner, wherein the sealing plate 20 includes a top sealing plate and a bottom sealing plate respectively covering the top surface and the bottom surface of the cooling main body 10, so as to simultaneously seal the cooling passages 13 on the top surface and the cooling passages 13 on the bottom surface.
Thus, when the cooling plate is thick, the cooling channels 13 with a shallow depth can be respectively machined on the top surface and the bottom surface of the cooling plate, so that not only is machining convenient, but also the same cooling speed can be provided on the top surface and the bottom surface at the same time; in addition, the depths of the cooling channels 13 at the top and bottom surfaces may also be unequal, i.e., the distances between the cooling channels 13 and the top and bottom surfaces are unequal, thereby providing different cooling rates at the top and bottom surfaces; thirdly, since the cooling passages 13 on the top surface and the bottom surface are arranged in a staggered manner, a small amount of processing can be performed on the cooling body 10 in a longitudinal direction perpendicular to the plate surface of the cooling plate, and the cooling body 10 can be protected as much as possible.
In addition, regardless of whether the cooling channels 13 are disposed on the top surface or the bottom surface of the cooling body 10, or are disposed on the top surface and the bottom surface of the cooling body 10 at intervals, cooling areas with different cooling effects can be formed on the surface of the cooling plate by controlling the depth of the cooling channels 13 in the cooling plate, so that objects to be cooled can be correspondingly placed on the different cooling areas on the surface. In specific application, a certain laser instrument probably has different work effect under different ambient temperature, or need place multiple laser instrument that has different heat production specifications simultaneously, these demands can all be satisfied to the cooling plate that this application provided.
As a preferred embodiment of the present invention, a plurality of the cooling channels 13 have a predetermined arrangement of pipe cross-sectional areas along the length direction. At the same pressure, the larger the cross-sectional area of the pipe, the greater the amount of cooling medium that can be circulated at the same time, and thus more heat can be removed. Therefore, the distribution of the pipeline cross-sectional areas with the predetermined arrangement rule in the plurality of cooling channels 13 can realize the cooling speed with the predetermined arrangement rule, for example, realize the situation that the local cooling speed is fast, for example, realize the situation that the cooling speed is gradually increased or decreased from the left end to the right end of the cooling plate, for example, realize the situation that the cooling speed is gradually increased or decreased from the two ends to the middle of the cooling plate. All can correspond the setting according to actual need above.

Threaded holes 15 are also uniformly distributed in the circumferential direction of the sealing plate 20 and the cooling body 10, so that the sealing plate 20 can be detachably connected to the cooling body 10 by screws.
It should be noted that, in order to improve the sealing reliability of the sealing plate 20 to the cooling channel 13, a sealing ring is further disposed between the positioning protrusion and the limiting groove 14.
It should be noted that the present description only provides some exemplary illustrations of the distribution of the cross-sectional area of the pipe according to the predetermined arrangement rule, and other distribution rules that can occur to those skilled in the art under certain specific needs should be within the scope of the present invention.
It is worth mentioning that in the process of long-term cooling, some impurities such as rust, dissolved substances, and colloid in the cooling medium are easily attached to the cooling inlet channel 11 and the cooling outlet channel 12 of the cooling plate, so as to affect the circulation of the cooling medium in the cooling plate, and further affect the cooling efficiency of the cooling plate. Therefore, the cold inlet pipe 112 and the cold outlet pipe 122 are detachably disposed in the cold inlet passage 11 and the cold outlet passage 12, respectively.
