Description

Technical Field

[0001] This utility model relates to a numerical control liquid cooling system, belonging to the technical field of welding machine auxiliary equipment. Background Technology

[0002] In the welding industry, cooling systems are typically used to cool components such as welding torches to handle high-current welding operations. Currently, common liquid cooling systems on the market have the following structural and functional defects:

[0003] 1. If the water pump is located in a non-dustproof chamber, it can easily damage the water pump motor.

[0004] 2. The water bucket is directly fixed to the base. When the liquid level is low, the water supply pressure to the water pump is insufficient.

[0005] 3. External filters weaken the effective protection of the water pump.

[0006] 4. The water level in the tank needs to be checked regularly through the observation window. If the water level in the tank is too low and is not detected, it will lead to reduced cooling performance and, in severe cases, damage to the water pump due to dry running.

[0007] 5. The lack of water quality detection and alarm function can lead to high-temperature scaling when the water quality is poor, which can damage water pumps, welding torches, etc.

[0008] 6. The lack of a high-pressure relief circuit means that if the water pump continues to run after the external pipeline is disconnected, the pressure in the pump outlet pipe will increase, which can easily cause damage to the pump and leakage in the pipeline.

[0009] Therefore, those skilled in the art urgently need to improve existing liquid cooling systems. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The present invention will be further described below with reference to specific embodiments.

[0032] Example 1:

[0033] This embodiment describes a numerically controlled liquid cooling system, such as... Figure 1 , 2 As shown, the device includes: a housing 1, which contains: partition A101, partition B102, partition C103, and partition D104. Partition B102 is connected to partition C103, isolating the interior of the housing into a left cavity and a right cavity. Partition D104 is disposed within the left cavity, isolating the left cavity into an upper left cavity and a lower left cavity. Partition A101 is disposed within the right cavity, isolating the right cavity into an upper right cavity and a lower right cavity.

[0034] A water tank 2 is installed in the upper right cavity. A water pump 3 is installed in the lower right cavity.

[0035] This utility model adopts a multi-dustproof chamber structure, in which the water bucket is installed above the water pump, which increases the water supply pressure to the water pump and effectively improves the success rate of water pump priming.

[0036] Furthermore, a transformer 4 and a control PCB board 5 are installed in the upper left cavity. A fan 6 and a heat sink 7 are installed in the lower left cavity. This arrangement disperses the main components, improving the dustproof performance of the transformer, control PCB board, and water pump.

[0037] Furthermore, a side door panel 8 is provided on the shell 1 corresponding to the upper right cavity to facilitate adding water to the bucket.

[0038] Furthermore, a filter 9 is installed at the outlet of the water tank 2 via a quick-connect fitting. This effectively protects the water quality entering the water pump and welding torch from the source.

[0039] Furthermore, such as Figure 3 As shown, the filter 9 includes a mounting part 901, an inlet 902 and an outlet 903, and quick-connect fittings 904 on both the inlet 902 and the outlet 903. A removable filter element 905 is installed inside the mounting part 901, and a protective shell 906 is installed outside the filter element 905. This facilitates installation and regular cleaning.

[0040] Furthermore, such as Figure 4 As shown, a liquid level sensor 10 is installed on the partition B102 on one side of the water tank 2. It is used to collect the liquid level signal of the water tank in real time.

[0041] Furthermore, such as Figure 5 , 6 As shown, the water outlet of the water tank is connected to the water inlet pipe 12 of the water pump, the water outlet pipe 13 of the water pump is connected to the water outlet connector 14, the return water connector 15 is connected to the water inlet pipe 17 of the radiator through the first return water pipe 16, and the water outlet pipe 18 of the radiator is connected to the water inlet of the water tank through the second return water pipe 19. A pressure relief pipe 20 is connected between the water outlet connector 14 and the return water connector 15. This is used so that when the external pipeline is blocked or disconnected, part of the high-pressure coolant coming out of the water pump can return to the water tank through the pressure relief circuit, avoiding damage to the water pump and rupture of the water pipe.

[0042] Furthermore, a water quality sensor 21 is installed on the first return water pipe for real-time measurement of the return water quality.

[0043] Furthermore, a flow sensor 22 is installed on the first return water pipe to measure the flow rate of the return water in real time.

[0044] Furthermore, the housing 1 includes: a front panel 105, on which a power switch 23, a display panel 24, and an air outlet 25 are provided.

[0045] Furthermore, the control PCB board is connected to the display board, water quality sensor, flow sensor and liquid level sensor respectively.

[0046] Furthermore, the radiator 7 adopts an integrated radiator structure.

[0047] Example 2:

[0048] This embodiment describes the working principle of a CNC liquid cooling system. During use, the power is turned on, activating the control PCB board and transformer. The transformer supplies power to the water pump and fan. The water pump draws water from the tank, which is then filtered to ensure the quality of the cooling water entering the pump and welding torch. The filtered cooling water is sent to the welding torch through the outlet connector. The return water from the welding torch enters the first return water pipe 16 through the return water connector. At this time, the water quality and flow rate of the return water are detected, and the data are sent to the control PCB board. The control PCB board determines whether the water quality and flow rate are within control thresholds. If they are not within the control thresholds, the control PCB board issues an alarm message, which is displayed on the display panel. The detected return water passes through the radiator and returns to the tank.

[0049] When the external pipeline is blocked or disconnected, some of the high-pressure coolant coming out of the water pump can return to the water tank through the pressure relief circuit.

[0050] The liquid level sensor collects the liquid level in the water tank in real time and sends it to the control PCB board. The control PCB board determines whether the liquid level in the water tank is within the control threshold. If it is not within the control threshold, the control PCB board issues an alarm message, which is displayed on the display board.

[0051] Additionally, the water tank can be refilled and the filter replaced via the side door panel.

[0052] The liquid cooling system adopts a multi-dustproof chamber structure. The water pump is installed in the lower rear dustproof chamber, while the control PCB board and electrical components are installed in the upper front dustproof chamber, which improves the overall dustproof capability of the product.

[0053] The water tank is installed above the water pump, which increases the water supply pressure to the pump and effectively improves the success rate of water priming. The water tank is connected to the water pipe with a quick-connect coupling, which makes it easy to remove the water tank and facilitates regular replacement of the coolant and cleaning of the water tank.

[0054] The filter is installed at the outlet of the water tank, and the filtered cooling liquid is then delivered to the water pump and welding torch. Compared with an external filter, it effectively protects the water pump and welding torch from the source. The filter adopts a quick-connect installation method, which is convenient for regular cleaning.

[0055] A non-contact liquid level sensor is installed on the sheet metal of the water tank's exterior to collect signals of the water level in real time, enabling intelligent detection of the water level and saving manpower.

[0056] A water quality monitoring sensor is installed on the return water pipe joint to monitor the coolant water quality in real time. When the water quality parameters exceed the set value, an alarm will be triggered through the display panel.

[0057] A pressure relief circuit is installed between the water outlet and the water return outlet. When the external pipeline is blocked or disconnected, part of the high-pressure coolant coming out of the water pump can return to the water tank through the pressure relief circuit, thus avoiding damage to the water pump and rupture of the water pipe.

[0058] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
