A cooling device for a laser thickness gauge according to a preferred embodiment of the present invention will be described in detail below with reference to fig. 1 to 3 of the specification, wherein the cooling device for a laser thickness gauge is used for cooling a laser sensor 10 of a laser thickness gauge, wherein the cooling device 30 includes a cooling block 40, and the cooling block 40 is attached to at least one side surface of the laser sensor 10. Since the laser sensor 10 is generally square in shape and has two side surfaces with relatively large areas, one of the side surfaces is used to be mounted on the adjusting block 20 of the laser thickness gauge so as to adjust the position of the laser sensor 10. When the cooling block 40 is attached to one side of the laser sensor 10, it is usually attached to the other side opposite to the adjusting block 20, so as to cool down the laser sensor 10 on the side with a larger surface area.

It is worth mentioning that, when ambient temperature is higher, in order to be better, faster right laser sensor 10 cools down, cooling block 40 also can be set up and paste simultaneously and establish a plurality of sides of laser sensor 10, for example surface, left and right sides and upper and lower surface etc. thereby the parcel laser sensor 10 can a plurality of sides of laser sensor 10 cool down simultaneously, further promote cooling efficiency.

A cooling duct 41 is disposed in the cooling block 40 in a direction parallel to the surface of the laser sensor 10, wherein the cooling duct 41 is provided with a duct inlet 411 and at least one duct outlet 412, so that a cooling medium circulates in the cooling duct 41 through the duct inlet 411 and the duct outlet 412, thereby removing heat of the laser sensor 10 through the continuous flow of the cooling medium.

It should be noted that, in the process of removing heat by the flow of the cooling medium in the cooling block 40, the cooling medium absorbs more and more heat as it flows. If the cooling pipe 41 is wound in the cooling block 40 for a plurality of turns and then flows out of the cooling block 40 through the pipe outlet 412, the amount of heat taken away when the cooling pipe 40 flows to a position close to the pipe outlet 412 is necessarily reduced, which is likely to cause uneven cooling of the laser sensor 10. Therefore, whether the cooling block 40 is attached to one side of the laser sensor 10 or to multiple sides of the laser sensor 10 at the same time, the duct outlets 412 are preferably provided in multiple numbers, and the duct outlets 412 face different directions or are distributed on different sides on the same side. That is to say, the cooling medium enters through the pipe inlet 411 and flows out through the different pipe outlets 412 in the cooling pipe 41, so that the retention time of the cooling medium in the cooling block 40 can be effectively reduced, instead of flowing out of the cooling block 40 through the pipe outlet 412 after being wound for multiple turns, and the heat generated by the laser sensor 10 can be taken away as soon as possible.

In one possible embodiment, the cooling medium is embodied as air cooling, which is preferably embodied as cold air, or liquid cooling, which is preferably embodied as water cooling, so that the heat of the cooling block 40 is removed by direct contact of the cold air or water with the cooling line 41, thereby achieving rapid cooling of the laser sensor 10.

As a preferred embodiment of the present invention, the cooling block 40 is kept away from the side of the laser sensor 10 is provided with the heat conducting groove 42, the cooling pipeline 41 is set in the heat conducting groove 42, and the heat conducting groove 42 is filled with the heat conducting member, wherein the heat conducting member is preferably implemented as the heat conducting glue, wherein the heat conducting glue is organic silica gel as the main body, and silica gel formed by mixing polymer materials such as filler, heat conducting material and the like is added, so that the heat conducting glue has better heat conducting and electrical insulating properties, and is widely used for electronic components. The heat-conducting glue is also called as: heat conductive silica gel, heat conductive silicone rubber, heat conductive silica gel, heat conductive silicone. The heat of the cooling block 40 is quickly conducted into the cooling pipeline 41 through the heat conducting glue, so that the heat is taken away through the cooling medium in the cooling pipeline 41, and the purpose of quickly cooling the laser sensor 10 is achieved. It is obvious that the implementation of the heat conducting member in the thermal conduction groove 42 as a heat conducting glue is only an exemplary illustration, and those skilled in the art will easily think of the relevant equivalent alternatives, which are not listed here, and are within the protection scope of the present application.

Further preferably, the pressing member 43 is implemented as a pressing plate, a pressing block or a pressing bar to be able to press the cooling pipe 41 in the temperature guiding groove 42 according to the shape, size and the like of the cooling block 40 and the shape, size and the like of the temperature guiding groove 42.

In general, the control device can set a fixed delivery parameter of the cooling medium, such as the flow rate and the flow rate of the cooling medium, according to the operating parameters of the laser sensor 10, the ambient temperature, and other factors, so as to achieve the purpose of controlling the automatic cooling. However, if some abnormal conditions occur, which results in a sudden increase of the heat generation of the laser sensor 10, it will easily affect the normal operation of the laser sensor 10. Therefore, as a preferred embodiment of the present invention, the cooling block 40 is provided with a temperature sensor 50, such as a thermal patch attached to the cooling block 40, to monitor the temperature of the cooling block 40 in real time, so as to be able to reversely deduce the current temperature of the laser sensor 10;
