Description

Technical Field

[0001] The utility model relates to the field of optoelectronic components, in particular to a water-cooled laser crystal seat. Background Art

[0002] The laser cavity is the cavity that generates the laser light path. The laser crystal seat in the laser cavity is the location where the laser crystal is installed in the laser.

Therefore, the laser crystal seat is required to have good heat dissipation. However, in the existing technology, it is usually adopted to add water channels to the base where the laser crystal seat is installed for heat dissipation. Not only is the heat dissipation effect poor, but it also causes problems such as uneven heat dissipation and susceptibility to changes in ambient temperature. Utility Model Content

[0044] The present invention is described in detail below through exemplary implementations. It can be understood that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "inside", "outside", "up", "down", "front", "back", "left", "right", "bottom", "top", etc. indicate directions or positional relationships based on the positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0046] Terms such as "head end", "tail end", "first end", and "second end" do not limit the order and direction, but are only used to distinguish the two ends of a waterway.

[0047] The words "first", "second", "third" and so on are only used to distinguish components or structures with different positions or functions, and do not indicate the order or priority of the components or structures. However, "first" does not mean that the components are exactly the same. For example, multiple "vertical waterways" do not mean that each vertical waterway is exactly the same. For example, the directions of the first vertical waterway and the second vertical waterway can be different. Accordingly, the "vertical" in this article is not limited to the direction perpendicular to the bottom surface. As long as it is a direction connecting any point on the bottom surface to any point on the top surface, it is "vertical".

[0048] The terms "fluid communication" and "fluid communication with..." applied between different waterways and different openings mean that a fluid can flow from one waterway to another waterway, or that a fluid flows from one opening to another opening; in some embodiments, the fluid communication between different openings can be achieved by connecting two openings via a waterway to achieve fluid communication, or by contacting two openings and connecting them via a pipe connection component to achieve fluid communication. "Fluid communication" herein particularly means that a liquid can easily flow from one waterway to another waterway, for example, the liquid is water.

[0049] Herein, "plurality" means two or more, for example, two, three, four, five, six or more.

[0050] In this article, "each" means all without exception; for example, "each vertical water channel" refers to all vertical water channels that are set up, such as the first vertical water channel and the second vertical water channel.

[0051] like Figures 1 to 10 As shown, this embodiment provides a water-cooled laser crystal holder, including a base and a cover plate.

[0052] The base includes a bottom surface and a top surface, and a base body sandwiched between the bottom surface and the top surface;

[0053] The cover plate comprises an upper surface and a lower surface, and a cover plate body sandwiched between the upper surface and the lower surface;

[0054] The cover plate and the base are detachably mounted so that the lower surface of the cover plate contacts and is fixed to the top surface of the base. The shape of the lower surface of the cover plate is adapted to the shape of the top surface of the base and can fit and seal with each other. Figure 2 As shown;

[0055] A crystal receiving slot is provided on the base;

[0056] A plurality of first water channels are arranged in the base, and each vertical water channel has a first direction extending from any point of the bottom surface to any point of the top surface; in other words, the vertical water channel extends along the height direction of the base.

[0057] A plurality of circulating water channels are arranged in the cover plate, each of the circulating water channels has a second direction, and each of the second directions has an angle greater than 0° and less than or equal to 90° with any of the first directions; in other words, the circulating water channel only needs to not extend in the same direction as the vertical water channel; thereby, a staggered water channel distribution can be formed inside the base and the cover plate, surrounding the crystal receiving tank from different sides and directions;

[0058] Each of the vertical water channels is fluidly connected to at least one of the circulating water channels, and the multiple circulating water channels intersect with each other and are fluidly connected at the intersections; thereby, the water channels staggered inside the base and the cover plate can be connected to form a network, thereby dissipating heat and cooling the crystal from different sides and directions.

[0059] In some specific embodiments, the vertical water channel may be perpendicular to the bottom surface at an angle of 90°; the vertical water channel may also have an angle less than 90° with the bottom surface, that is, the vertical water channel may be inclined at a certain angle in any direction relative to the vertical line of the bottom surface, as long as it can connect any point on the bottom surface with any point on the top surface. The first direction of each vertical water channel may be the same or different; for example, a first vertical water channel and a second vertical water channel are provided, the first vertical water channel has a first direction perpendicular to the bottom surface, and the second vertical water channel has a first direction with an angle less than 90° with the bottom surface, for example, with an angle of 75° with the bottom surface.

[0060] Each circulating water channel may also have a different second direction, as long as the circulating water channels are fluidically connected to each other.

[0061] Each vertical water channel is provided with a bottom opening and a top opening at both ends, the bottom opening is opened on the bottom surface of the base, and the top opening is opened on the top surface of the base;

[0062] Each circulating water channel is provided with a first end opening and a second end opening at both ends, wherein the first end opening is provided on the side wall of the cover body, so that the circulating water channel extends horizontally, forming an extension direction different from that of the vertical water channel, thereby realizing multi-angle circulating cooling of the crystal holding tank, such as Figure 3 shown.

[0063] In one embodiment, the number of vertical water channels is the same as that of circulating water channels, and the second end opening of the circulating water channel is disposed on the lower surface of the cover plate. Figure 4As shown. The second section opening directly contacts and is fluidically connected with the top opening of the vertical water channel in a one-to-one correspondence. For example, the top opening of the first vertical water channel is arranged on the top surface, and a second end opening of the circulating water channel is arranged on the lower surface of the cover plate at a position corresponding to the top opening, and the top opening is connected to the second end opening to achieve fluid communication. The connection method of the two openings can adopt a pipeline connection method known in the art, such as providing a pipeline interface and a sealing ring that can cooperate with each other. When the cover plate is installed to the top surface of the base, the top opening contacts and matches with the corresponding second end opening, and the sealing ring is used to prevent fluid from overflowing.

[0064] In another embodiment, the second end opening of the circulating water channel is also disposed on the side wall of the cover body. Figure 5 As shown, at this time, the circulating water channel runs through different side walls of the cover body in a transverse distribution manner, and is not directly connected to the vertical water channel. A plurality of connecting water channels can be arranged in the cover, and the number is the same as or different from the number of vertical water channels. One end of each connecting water channel is a connecting port arranged on the lower surface of the cover, and the connecting port corresponds to the top opening of the vertical water channel one by one, and they are in contact with each other and fluidly connected; the other end of the connecting water channel is connected to any circulating water channel and is fluidically connected; specifically, the connecting water channel is connected to any position between the two ends of the circulating water channel. It can be understood that in this embodiment, the vertical water channel and the circulating water channel are fluidically connected and circulated through the connecting water channel. In some specific embodiments, a circulating water channel connecting strip connects the water channels; in other specific embodiments, a plurality of connecting water channels are connected to a circulating water channel.

[0065] In one embodiment, the first end opening and the second end opening of each circulating water channel are respectively arranged on opposite side walls. Figure 1 Taking the shown orientation as an example, the first end opening of the first circulating water channel can be set on the left side wall of the cover body, and the second end opening is set on the right side wall of the cover body. The first end opening of the second circulating water channel can be set on the front side wall of the cover body, and the second end opening is set on the rear side wall of the cover body. The first circulating water channel and the second circulating water channel intersect and penetrate at the intersection.

[0066] As a specific example, Figures 5 to 8 As shown, a water-cooled laser crystal base has two vertical water channels arranged on the base perpendicular to the bottom surface of the base: a first vertical water channel and a second vertical water channel, respectively having a first top opening, a first bottom opening, a second top opening, and a second bottom opening, each top opening and bottom opening being provided with a sealing ring installation position, and a sealing gasket being installed;

[0067] A first circulating water channel and a second circulating water channel are arranged in the cover plate in a direction parallel to the upper surface of the cover plate (for example, in a horizontal direction). The first end opening of the first circulating water channel is arranged on the left side wall of the cover plate body, and the second end opening is arranged on the right side wall of the cover plate body. The first end opening of the second circulating water channel is arranged on the front side wall of the cover plate body, and the second end opening is arranged on the rear side wall of the cover plate body. The first circulating water channel and the second circulating water channel intersect vertically and penetrate at the intersection, thereby realizing internal fluid communication. Each first end opening and the second end opening are provided with a sealing plug to prevent cooling water from overflowing. In addition, two connecting water channels are arranged in the cover plate: a first connecting water channel and a second connecting water channel. The connecting port of the first connecting water channel corresponds to and is connected to the position of the first top opening, and the other end extends to be connected to the first circulating water channel. The connecting port of the second connecting water channel corresponds to and is connected to the position of the second top opening, and the other end extends to be connected to the second circulating water channel.

[0068] When the water-cooled crystal seat is working, cooling water can be introduced through the first bottom opening of the bottom surface, and the cooling water flows into the first circulating water channel through the first vertical water channel and the first connecting water channel. The first circulating water channel and the second circulating water channel intersect and fluid flows, so the cooling water then flows into the second circulating water channel, circulates inside the circulating water channel, and then flows out from the second bottom opening through the second connecting water channel and the second vertical water channel, completing water circulation cooling and heat dissipation.

[0069] Cooling water may also be introduced from the first bottom opening and the second bottom opening at the same time, and after the cooling water circulates in the water channel for a certain period of time, the cooling water is discharged from the first bottom opening and the second bottom opening.

[0070] In other embodiments, the direction and position of any one or more water channels can be changed, as long as each water channel can achieve multi-directional fluid communication between the cover plate and the base. For example, the first circulating water channel intersects with the second circulating water channel, but an angle is less than 90°. For another example, the vertical water channel is at an angle of 75° to the vertical line of the bottom surface. For another example, the circulating water channels are distributed on a plane that is at an angle of 15° to the upper surface of the cover plate. Any expected changes in the direction and position of the water channels are included in the scope of this application.

[0071] In other embodiments, the number of vertical water channels, connecting water channels and circulating water channels can be changed, and can be 2, 3, 4 or more respectively, as long as each top opening of the vertical water channel is connected to a connecting port of the connecting water channel and is connected to the circulating water channel fluid.

[0072] In some embodiments, the crystal receiving groove is provided with an opening on the top surface facing the base, and the lower surface of the cover plate contacts the top surface and covers the opening to form a crystal receiving cavity.

[0073] In all the above embodiments, the vertical water channel and the circulating water channel are arranged around the crystal holding tank. In some cases, the vertical water channel and the circulating water channel are not connected to the crystal holding tank.

[0074] The above water-cooled laser crystal seat can be prepared by a molding process known in the art, such as an injection molding process or a 3D printing process.

[0075] The water-cooled laser crystal seat provided in the embodiment of the present application forms a water channel heat dissipation circulation network by simultaneously arranging multiple water channels in different directions and connected by fluid in the base and the cover plate, thereby increasing the heat dissipation area, improving the heat dissipation efficiency, and maintaining the original crystal accommodation structure of the crystal seat. The overall external structure changes little, the cost is low, and the heat dissipation effect can be improved without changing the original basic design of the crystal seat.

[0076] In the above embodiments, all technical solutions under the concept of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
