Description

Technical Field

[0001] This utility model belongs to the field of heat exchanger technology, specifically relating to a high-efficiency water-cooled unit. Background Technology

[0002] High-efficiency and environmentally friendly water-cooled units are core energy-saving devices that achieve cooling through water circulation. Their structure mainly includes a refrigeration cycle system, compressor, condenser, evaporator, water circulation auxiliary system, and intelligent control system. Through evaporation to absorb heat, compression to raise temperature, and condensation to release heat, the water circulation delivers the cooled water to the terminal equipment. The core advantages of this unit are high efficiency and energy saving, stability and reliability, environmental protection with low impact, and wide applicability.

[0003] Currently, the compressors in water-cooled units usually come with an oil separator. The oil separator is usually located at the compressor's exhaust port. After the airflow from the compressor's exhaust port passes through the oil separator, there will be a large pressure drop. The large pressure drop leads to low evaporation pressure, resulting in low evaporation temperature, and consequently, low energy efficiency. Utility Model Content

[0014] In one embodiment, a one-way valve is also included, and the other ends of the first and second air intake pipes are converged at one point and connected to the convergence pipe through the one-way valve.

[0015] By connecting a one-way valve between the end of the manifold and the two intake pipes, the exhaust resistance is greatly reduced compared to the previous exhaust shut-off valve, thereby improving the overall energy efficiency.

[0016] In one embodiment, an oil storage tank is also included, which is connected to the inner bottom of the oil separator and is used to store the oil separated by the oil storage tank.

[0017] The oil separated from the oil separator is sent to the oil storage tank to prevent the oil from re-entering the subsequent circulation system and to improve the efficiency of oil separation.

[0018] In one embodiment, the oil reservoir is also connected to an oil return line, the other end of which is connected to the compressor, and a dryer filter is connected in series in the oil return line.

[0034] Example

[0035] like Figure 1-2 As shown, the present invention provides a high-efficiency water-cooled unit, which includes: an evaporator 1, a condenser 2, a compressor 3, and an exhaust pipe assembly 4.

[0036] Evaporator 1 and condenser 2 are arranged side by side, with condenser 2 located on one side of evaporator 1. Both ends of condenser 2 and evaporator 1 include tube sheets 12, and base plates 13 are provided at the bottom of tube sheets 12 at both ends. Evaporator 1 and condenser 2 are fixed at the target position by the base plates 13.

[0037] The compressor 3 is installed on top of the condenser 2 or the evaporator 1. The bottom of the compressor 3 is fixed to the top of the evaporator 1 by the compressor 3 bracket. The air inlet of the compressor 3 is connected to the top of the evaporator 1 through the air inlet steel pipe.

[0038] The compressor 3 has two exhaust ports. The exhaust pipe group 4 includes a first intake pipe 401, a second intake pipe 402, and a collection pipe 403. One end of the first intake pipe 401 and the second intake pipe 402 are respectively connected to the two exhaust ports of the compressor 3. One end of the collection pipe 403 is connected to the other end of the first intake pipe 401 and the second intake pipe 402. The other end of the collection pipe 403 is connected to the condenser 2.

[0039] Specifically, the first intake pipe 401 and the second intake pipe 402 are connected to one end of the main pipe 403 via a tee fitting, ensuring that the airflow from the first intake pipe 401 and the second intake pipe 402 smoothly enters the main pipe 403 and then enters the subsequent condenser 2.

[0040] An oil separator is installed inside the condenser 2. The oil separator is connected to the other end of the collection pipe 403. The exhaust gas from the compressor 3 is sent into the oil separator inside the condenser 2 through the exhaust pipe group 4 to reduce the pressure drop at the exhaust port of the compressor 3.

[0041] By placing the oil separator inside the condenser 2, compared to the previous method of placing the oil separator at the exhaust port of the compressor 3, the exhaust resistance of the compressor 3 is reduced and the pressure drop is decreased. Similarly, by setting two exhaust ports for the compressor 3 and connecting them with two intake pipes, the resistance of the gas in the pipeline is reduced, thereby increasing the evaporation temperature, decreasing the condensation temperature, and thus improving the overall energy efficiency.

[0042] To further reduce pressure drop, a one-way valve is also provided. The other ends of the first intake pipe 401 and the second intake pipe 402 converge at one point and are connected to the convergence pipe 403 through the one-way valve. Specifically, the end of the tee is connected to the one-way valve, and one end of the convergence pipe 403 is connected to the other side of the one-way valve. By connecting the one-way valve between the convergence pipe 403 and the ends of the two intake pipes, the exhaust resistance is greatly reduced compared to the previous exhaust shut-off valve, thereby improving the overall energy efficiency.

[0043] like Figure 2 As shown, it also includes an oil storage tank 6, which is connected to the bottom of the oil separator and is used to store the oil separated by the oil storage tank 6. Specifically, a horizontal oil collection pipe is provided outside the condenser 2, and the return oil pipe is connected to the lowest point in the oil separator. The oil collection pipe is connected to the oil storage tank 6, so that the oil separated in the oil separator is sent into the oil storage tank 6 through the oil collection pipe, so as to avoid the oil from repeatedly entering the subsequent circulation system and improve the oil separation efficiency.

[0044] Furthermore, the oil storage tank 6 is located between the evaporator 1 and the condenser 2, which facilitates the connection of pipelines on the oil storage tank 6. Specifically, multiple support plates 11 are connected to the oil storage tank 6, and the support plates 11 are connected to the condenser 2 or the evaporator 1. The oil storage tank 6 is installed at a height lower than the bottom of the cylinder of the condenser 2 and the evaporator 1.

[0045] To enable the reuse of oil in the oil reservoir 6, an oil return line 7 is also connected to the oil reservoir 6. The other end of the oil return line 7 is connected to the compressor 3. A dryer filter 8 is connected in series in the oil return line 7, and a filter is installed in the oil return line 7 to filter the oil and then send it back to the compressor 3 for reuse.

[0046] To ensure that the oil level in the oil reservoir 6 is within a suitable range, neither too high nor too low, an oil level sensor 9 is installed on the oil reservoir 6 to control the amount of oil stored in the oil reservoir 6.

[0047] In this embodiment, the oil discharge port of the compressor 3 is also connected to an oil discharge pipe 10, and the other end of the oil discharge pipe 10 is connected to the oil storage tank 6.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
