Description

Technical Field

[0001] The present invention belongs to the technical field of laser chillers, and particularly relates to a post-laser water distribution structure of a laser chiller. Background Art

[0002] During the use of laser equipment, a large amount of heat is generated when the laser and the laser head are working, and a laser chiller is required to quickly dissipate the heat. Moreover, due to the different working temperatures and heat dissipation amounts of the laser and the laser head, the laser body needs to be cooled with low-temperature cooling water at a lower temperature, and the laser head needs to be cooled with normal-temperature cooling water at a higher temperature. The most commonly used to meet the above requirements is a single-unit dual-temperature laser chiller as Figure 1 shown. After the low-temperature cooling water is prepared, it is supplied to the laser and the laser head through two branches respectively. A normal-temperature heating device is also connected to the water pipe leading to the laser head. In this structure, the normal-temperature cooling water is prepared by heating the low-temperature cooling water. On the one hand, an additional electric heating device is required, resulting in a more complex structure and a larger volume of the chiller. On the other hand, the heating process causes additional consumption of the system's refrigeration capacity, generating ineffective refrigeration capacity. Therefore, the overall refrigeration efficiency of the equipment cannot be fully utilized, and there is also an internal energy consumption situation, increasing the energy consumption. Summary of the Invention

[0003] The purpose of the present invention is to provide a post-laser water distribution structure of a laser chiller that does not require a normal-temperature heating device, has a simpler and lighter structure, lower energy consumption, and a higher utilization rate of the system's refrigeration power.

One path of the water distribution pipe is connected to the low-temperature circuit L2, and the other path returns to the low-temperature water tank 1 after passing through the cooling circuit of the laser head to form a normal-temperature return water branch L3.

[0023] The present invention will be described in detail below in conjunction with specific embodiments.

[0024] The laser chiller's post-laser water distribution structure of the present invention is mainly used to provide an improved single-unit dual-temperature laser chiller structure. Its basic principle structure is as Figure 2 shown. Its main structure includes a low-temperature water tank 1, a water pump 2, an evaporator 3, a radiator 4, a compressor 5, a throttle pipe 6, and a water distribution pipe 7;

[0025] Among them, the compressor 5, the condenser 4, and the throttle pipe 6 are connected in sequence and communicate with the heat absorption side of the evaporator 3 to form a refrigeration cycle loop L1;

[0026] The refrigeration cycle loop L1 is filled with a cooling medium, which is used to take out the heat in the evaporator to achieve cooling on the refrigeration side.

[0027] Among them, the low-temperature water outlet of the low-temperature water tank 1 is connected to the laser radiator circuit through the water pump 2 and then forms a low-temperature water circulation loop through the heat dissipation side of the evaporator 3;

[0028] The water distribution pipe 7 is arranged on the water outlet side of the laser radiator circuit. One path of the water distribution pipe is connected to the low-temperature loop L2, and the other path returns to the low-temperature water tank 1 after passing through the heat dissipation circuit of the laser head to form a normal-temperature return water branch L3.

[0029] Among them, the low-temperature water circulation loop includes a low-temperature water outlet loop L20 connecting from the water pump 2 to the low-temperature water outlet, and a low-temperature water return loop L21 connecting from the low-temperature water return port to the evaporator 3.

[0030] The low-temperature water outlet loop L20 circulates the low-temperature cooling water flowing out from the low-temperature water tank. The low-temperature cooling water absorbs heat and warms up to become normal-temperature cooling water after passing through the laser. It is divided into two paths. One path passes through the low-temperature water return loop L21 and dissipates heat and cools down in the evaporator and then returns to the low-temperature water tank 1. The other path cools the laser head and then returns to the low-temperature water tank 1 through the normal-temperature return water branch L3; the low-temperature water return loop L21 carries the excess heat and dissipates it through the condenser.

[0031] To facilitate the control of the flow rate ratio of the normal temperature cooling water flowing through the laser head and returning to the evaporator, so as to achieve precise distribution control of the cooling water flow rate and refrigeration efficiency, a flow control valve is also provided on the water distribution pipe 7.

[0032] Specifically, in this embodiment, an installation box body 10 for installing the above structure is also provided. The installation box body 10 is a cuboid shell structure with air inlets opened on the left and right side shell surfaces; grid plates and filter structures are provided at the air inlets on the left and right sides.

[0033] An installation opening is provided on the rear side shell of the installation box body 10. Among them, the radiator 4 is arranged inside the installation opening, and a cooling fan 8 is arranged outside the installation opening.

[0034] The installation box body 10 further includes a bottom mounting plate 11, and a plurality of positioning mounting holes 11a are provided on the bottom mounting plate 11;

[0035] The low-temperature water tank 1 is installed on the front side of the bottom mounting plate 11. The water pump 2 and the compressor 5 are respectively located between the low-temperature water tank 1 and the radiator 4. The low-temperature water tank 1, the water pump 2 and the compressor 5 are fixed by a bolt group arranged in the positioning mounting holes 11a;

[0036] To facilitate the replenishment of the consumption of the cooling water, a water replenishing pipe 1a is installed above the front side of the low-temperature water tank 1. At the same time, to facilitate the cleaning of the low-temperature water tank, a drain pipe 1b is installed below the front side of the low-temperature water tank 1.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
