Description

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to a chiller circulation testing device. Background Technology

[0002] Chillers are widely used in injection molding, die casting, PCB / semiconductor processes, laser processing, lithium battery production, pharmaceuticals and chemicals, data centers, and building air conditioning, providing a cooling medium (usually water or a water / glycol mixture) at constant temperature, flow rate, and pressure. To verify the performance and reliability of chillers under factory and field conditions, dedicated cyclic testing equipment (test loops) are generally required in the R&D and production stages to conduct type testing, performance calibration, durability and extreme condition testing, and control function verification.

[0003] The aforementioned existing technical solutions have the following drawbacks: traditional testing devices cannot accurately test temperature / flow rate, which may cause damage to the workpiece during use. Utility Model Content

[0004] The purpose of this invention is to provide a chiller circulation testing device to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A chiller circulation testing device includes a first water tank, a second water tank, and a third water tank. A water pump is fixedly installed on the top of the first water tank. A first circular hole is provided at the bottom of the left end face of the first water tank, with the axis of the first circular hole oriented left-right. A temperature sensor is provided at the top of the front end face of the first water tank. The second water tank is fixedly installed at the rear end of the first water tank. There is a gap between the rear end face of the first water tank and the front end face of the second water tank. A second circular hole is provided at the bottom of the rear end face of the second water tank, with the axis of the second circular hole oriented front-back. A temperature sensor is provided at the top of the rear end face of the second water tank. The third water tank is fixedly installed on the right side of the first water tank. There is a gap between the left end face of the third water tank and the right end faces of the first and second water tanks. A heater is fixedly installed at the top of the third water tank. A temperature sensor is provided at the top of the front end face of the third water tank.

[0007] By adopting the above technical solution, the temperature of the cooling medium can be efficiently and accurately controlled through the setting of heater and temperature sensor. The top-mounted heater does not directly contact the sediment or impurities that may exist at the bottom or side wall of the water tank, reducing the damage to the heater caused by impurities or bottom corrosion. It also allows staff to easily access the heater to set relevant parameters and start / stop it, improving the convenience and safety of operation.

[0008] In a further embodiment, an output pipe is fixedly installed on the right side of the first water tank, and the axis of the output pipe is collinear with the axis of the first circular hole.

[0009] By adopting the above technical solution, the collinearity between the axis of the output pipe and the axis of the first circular hole can ensure a sealed connection between the pipe and the water tank, reduce the risk of leakage, and ensure the stability and reliability of the entire fluid transport system.

[0010] In a further embodiment, a throttle valve is fixedly installed at the right end of the output pipe, and the axis of the throttle valve is collinear with the axis of the output pipe.

[0011] By adopting the above technical solutions, more precise flow control can be achieved, and the installation, maintenance and repair of pipeline systems can be facilitated. This reduces the difficulty and workload of operation, helps to reduce equipment downtime for maintenance, and improves overall work efficiency.

[0012] In a further embodiment, an input pipe is fixedly installed on the rear side of the second water tank, and the axis of the input pipe is collinear with the axis of the second circular hole.

[0013] By adopting the above technical solution, the collinearity between the axis of the input pipe and the axis of the first circular hole can ensure a sealed connection between the pipe and the water tank, reduce the risk of leakage, and ensure the stability and reliability of the entire fluid transport system.

[0014] In a further embodiment, a throttle valve is fixedly installed at the tail end of the input pipe, and the axis of the throttle valve is collinear with the axis of the tail end of the input pipe.

[0015] By adopting the above technical solutions, more precise flow control can be achieved, and the installation, maintenance and repair of pipeline systems can be facilitated. This reduces the difficulty and workload of operation, helps to reduce equipment downtime for maintenance, and improves overall work efficiency.

[0016] In a further embodiment, a third circular hole is provided on the right end face of the first water tank, and the axis of the third circular hole is arranged horizontally. A fourth circular hole is provided at the front end of the left end face of the third water tank, and the axis of the fourth circular hole is collinear with the axis of the third circular hole. A fifth circular hole is provided on the right end face of the second water tank, and the axis of the fifth circular hole is arranged horizontally. A sixth circular hole is provided at the rear end of the left end face of the third water tank, and the axis of the sixth circular hole is collinear with the axis of the fifth circular hole.

[0017] By adopting the above technical solution, the circular holes opened on each water tank ensure that the water tanks can be interconnected, thereby forming a circulation of cooling medium between the water tanks.

[0018] In a further embodiment, a one-way valve is fixedly installed between the third and fourth circular holes, the axis of the one-way valve being collinear with the axis of the third circular hole; a one-way valve is fixedly installed between the fifth and sixth circular holes, the axis of the one-way valve being collinear with the fifth circular hole.

[0019] By adopting the above technical solution, the sealing between each water tank is ensured through the setting of one-way valves, thus avoiding problems such as liquid leakage.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By setting up a one-way valve, it is possible to control whether the first water tank, the second water tank, and the third water tank are connected or not connected, and to seal them.

[0022] 2. The heater at the top of the third water tank can raise the temperature of the cooling medium;

[0023] 3. By setting a throttle valve, the flow rate of the cooling medium entering and exiting the chiller can be controlled. Attached Figure Description
