Heat dissipation plate for pump laser

Technical Field

The utility model relates to a laser instrument heat dissipation technical field especially relates to a heating panel for pumping laser instrument.

Background

Pumping refers to the process of energizing the laser working substance to form a population inversion. Pump lasers are very widely used. Along with the improvement of laser power, in the pumping solid laser, a pumping module can dissipate a large amount of heat in the process of improving the power, the heat consumption must be exhausted as soon as possible to ensure the normal operation of the laser, otherwise, the laser quality is reduced.

For example, in the technical scheme of 976nm pumping, the absorption peak of 976nm is very narrow, so that the central wavelength of a pumping source is drifted when the working environment temperature changes, and the performance index of the whole fiber laser is fluctuated. Therefore, the heat dissipation plate for dissipating heat of the pump source is very important, in order to achieve a good heat dissipation effect and meet the temperature uniformity of the surface of the heat dissipation plate, the temperature uniformity of the surface of the cold plate is mainly achieved through structures such as a micro-channel and a vacuum cavity soaking plate at the present stage, and the processing requirements on the heat dissipation plate are high at that time, so that the processing cost is increased rapidly.

Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 shows a heat dissipation plate for a pump laser according to an embodiment of the present invention, which includes a body 11, and the body 11 includes an upper end surface 111 and a lower end surface 112 that are oppositely disposed.

The upper end surface 111 of the body 11 is used for placing a plurality of pump lasers 30 thereon, the pump lasers 30 are usually fixed on the upper end surface 111 of the body 11 through a heat conducting glue, and the body 11 is made of a material with high heat conductivity, so that the heat of the pump lasers 30 can be efficiently conducted to the body 11.

A plurality of heat dissipation fins 50 are disposed on the lower end surface 112, referring to fig. 2, in the present embodiment, the heat dissipation fins 50 have the same height and are disposed on a plane, so as to support the heat dissipation plate on a plane; referring to fig. 3, in other embodiments, the heat dissipation fins 50 may be disposed higher and lower according to the shape of the supporting surface on which the heat dissipation plate is disposed, for example, the supporting surface is stepped, so as to be disposed on the stepped supporting surface; it can thus be seen that the fins 50 are provided at different heights to accommodate differently shaped support surfaces so that the heat sink plate can be placed on differently shaped support surfaces.

Six terminal surfaces of body 11 (including up end 111, lower terminal surface 112) and the surface of each fin 50 on lower terminal surface 112 all scribble and are equipped with graphite alkene layer, because graphite alkene layer has fabulous heat conductivility to can the efficient conduct the heat of pump laser 30 on the body 11 scribbles on the surface of graphite alkene layer, thereby can the efficient distribute away the heat of pump laser 30.

Referring to fig. 1, in order to efficiently take away heat from the body 11, a water inlet 115 and a water outlet (not shown) are respectively disposed at the left end and the right end of the body 11, a water channel (not shown) communicating the water inlet 115 and the water outlet is disposed in the body 11, and a coolant enters the water channel through the water inlet 115, absorbs heat conducted to the body 11 by the pump laser 30, and then flows out from the water outlet.

Referring to fig. 4, a heat dissipation fan 70 may be disposed at a corresponding position of the heat dissipation plate 50, so as to accelerate the airflow at the heat dissipation plate 50 and rapidly dissipate the heat at the heat dissipation plate 50.
