Description

Technical Field

[0001] This invention relates to the field of screw compressor cooling technology, and more specifically to an integrated evaporative cooling unit for screw compressors. Background Technology

[0002] As the core power component of a refrigeration system, the compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It undertakes the key functions of refrigerant circulation and pressurization and heat transfer. It is widely used in many fields such as industrial refrigeration, HVAC, chemical processes, and food cold chain, and is an indispensable core equipment of modern refrigeration and heat exchange systems.

[0003] Screw compressors, also known as spiral compressors, are mainly divided into screw air compressors and screw process compressors (such as vinyl chloride compressors). They employ a positive displacement twin-screw oil-injected structure and are mostly designed as integrated, skid-mounted units. With advantages such as stable operation, low vibration and noise, high volumetric efficiency, long service life, and convenient maintenance, they have gradually become the preferred type of compressor for medium and large-scale refrigeration systems. Compared to other compressor types, screw compressors can adapt to continuous high-load operation conditions, with a continuous and stable compression process and excellent gas-liquid separation. They can meet both conventional refrigeration and cooling needs and are suitable for special process compression scenarios in industries such as chemical and pharmaceutical, continuously expanding their application scope. Currently, traditional screw refrigeration units mostly use independent air-cooling or water-cooling methods, which have problems such as insufficient heat dissipation margin and low temperature control accuracy, making them difficult to meet the actual requirements of modern enterprises.

[0004] Therefore, we propose an integrated screw compressor evaporative cooling unit. Summary of the Invention

[0005] The main objective of this invention is to provide an integrated evaporative cooling unit for screw compressors. The compressed gas generated by the screw compressor body undergoes initial heat exchange and cooling in a horizontal shell-and-tube heat exchanger. A top fan starts simultaneously to accelerate heat dissipation. The evaporative cooler and auxiliary air-cooling module work together to perform secondary cooling on the heat-exchanged medium, forming a dual cooling structure. The unit adopts a box-type skid-mounted integrated form, with all components integrated and assembled on the frame and mounting base. It has a compact structure, small footprint, and can be fixedly installed as a whole using the mounting base, facilitating transportation and on-site deployment. This effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An integrated screw compressor evaporative cooling unit includes a horizontal shell-and-tube heat exchanger, an evaporative cooler, an electrical control box, a screw compressor body, an auxiliary air-cooling module, a liquid storage tank, columns, a frame, and a mounting base. The horizontal shell-and-tube heat exchanger is fixedly installed on one side of the upper end face of the frame. A top fan is provided at the top of the horizontal shell-and-tube heat exchanger. Support rods for installing a canopy are vertically welded at the four corners of the top of the horizontal shell-and-tube heat exchanger. The canopy is located directly above the horizontal shell-and-tube heat exchanger. Four sets of relatively parallel columns are vertically welded on the upper end face of the frame away from the horizontal shell-and-tube heat exchanger. The evaporative cooler is fixedly installed between the four sets of relatively parallel columns. A liquid storage tank and an auxiliary air-cooling module are also installed below the evaporative cooler. Protective nets are provided at both ends of the evaporative cooler. The evaporative cooler and the auxiliary air-cooling module are both located on one side of the horizontal shell-and-tube heat exchanger. The electrical control box and the screw compressor body are respectively installed at the top of the horizontal shell-and-tube heat exchanger. The frame is mounted on a mounting base. A baffle for defining the position of the horizontal shell-and-tube heat exchanger is vertically connected to one side of the upper end face of the mounting base. A protective mechanism for protecting the horizontal shell-and-tube heat exchanger, the electrical control box, and the screw compressor body is slidably connected to the side of the upper end face of the frame away from the baffle. The protective mechanism includes a positioning plate, a crossbar, side mesh plates, a protective cover, and a top beam. The protective cover has side mesh plates vertically connected to both ends. Two side mesh plates are arranged in parallel to each other. The protective cover and the two opposing side mesh plates together enclose a storage cavity on the upper surface of the frame.

[0007] By adopting the above technical solution, the entire unit can be fixed in a designated position using the mounting base. The protection mechanism can be slid along the slide to the closed position and fixed using the positioning plate and fasteners. After the electrical control box is set with parameters, it can operate normally. The entire operation is simple and easy to understand. During maintenance, simply loosen the bolts on the positioning plate and fasteners and slide the protection mechanism to the open position to conveniently inspect and maintain core components such as the horizontal shell-and-tube heat exchanger, electrical control box, and screw compressor body. This effectively reduces maintenance time and the workload of maintenance personnel. When the unit is running, the compressed gas generated by the screw compressor body undergoes initial heat exchange and cooling in the horizontal shell-and-tube heat exchanger. The top fan starts simultaneously to accelerate heat dissipation. The evaporative cooler and the auxiliary air-cooling module work together to perform secondary cooling on the heat-exchanged medium, forming a dual cooling structure. Compared with traditional independent air-cooling or water-cooling methods, the heat dissipation margin is sufficient, and the medium temperature can be accurately controlled within the set range. This solves the problems of insufficient heat dissipation and low temperature control accuracy of traditional screw chiller units.

[0008] Specifically, two protective nets are arranged in parallel. The bottom of the protective nets is fixedly connected to both ends of the upper surface of the frame, and the protective nets are located between two adjacent columns. The bottom of the auxiliary air-cooling module is fixedly connected to the upper surface of the frame. The auxiliary air-cooling module and the horizontal shell-and-tube heat exchanger are both located between the two protective nets.

[0009] Specifically, the protective cover is an inverted L-shaped structure. A top beam is fixedly connected to the top of the protective cover near the side of the horizontal shell and tube heat exchanger. Both ends of the top beam are fixedly snapped to the upper part of one side of the side mesh plate. A crossbar is fixedly connected to the bottom of the protective cover. The crossbar is located above the frame. A third groove that matches the top of the fastener is provided at the center of the bottom of the crossbar.

[0010] Specifically, both ends of the crossbar are vertically inserted into the lower part of one side of the side mesh plate. The side mesh plate is set parallel to the protective net. A positioning plate is fixedly inserted into the lower part of the side mesh plate near the protective net. The end of the positioning plate away from the side mesh plate is fixedly connected to the upper end face of the mounting base by a positioning bolt.

[0011] By adopting the above technical solutions, the unit adopts a box-type skid-mounted integrated form, with all components integrated and assembled on the frame and mounting base. The structure is compact and occupies a small area. It can be fixedly installed as a whole through the mounting base, which is convenient for transportation and on-site deployment and can adapt to the needs of different installation scenarios. At the same time, the screw compressor body adopts a positive displacement twin-screw oil injection structure, which runs smoothly and has low vibration and noise. Combined with a complete cooling and protection structure, the whole unit can meet the needs of modern enterprises for efficient, stable and convenient use of screw compressors.

[0012] Specifically, the bottom end of the side mesh plate is provided with a sliding strip, and the upper end face of the mounting base is provided with sliding grooves on both sides that are adapted to the sliding strip. The upper end face of the mounting base is also provided with second grooves on both sides for installing fasteners. The fasteners are fastened to both ends of the frame from top to bottom, and the bottom end of the fasteners is fixedly connected to the mounting base by second bolts.

[0013] Specifically, the mounting base has a through hole at the center of its upper end face, and a crossbeam for supporting the frame is fixedly connected to the through hole at the upper end face of the mounting base. The mounting base has a first groove for installing fasteners at the center of the end away from the baffle. The bottom end of the fastener is located in the first groove and is fixedly connected to the mounting base by a first bolt. The top end of the fastener is engaged with the side of the frame away from the baffle.

[0014] Specifically, the upper end face of the mounting base near the baffle is provided with positioning grooves for installing positioning components at both ends. The mounting base is provided with drainage holes at both ends of the positioning grooves, which are connected to the positioning grooves. The bottom end of the positioning component is fixedly connected to the mounting base by a third bolt, and the top end of the positioning component is fixedly connected to the lower part of the column by a fourth bolt.

[0015] Specifically, a protective cavity is provided between the horizontal shell-and-tube heat exchanger and the roof, and multiple sets of top fans are arranged in parallel with each other, with all sets of top fans located inside the protective cavity.

[0016] The beneficial effects of this invention are: The screw compressor evaporative cooling integrated unit described in this invention can be fixed in a designated position using a mounting base. The protection mechanism is slid along the slide groove to the closed position and secured using a positioning plate and fasteners. After setting the parameters in the electrical control box, it can operate normally. The entire operation is simple and easy to understand. During maintenance, simply loosen the bolts on the positioning plate and fasteners, and slide the protection mechanism to the open position for convenient maintenance of core components such as the horizontal shell-and-tube heat exchanger, electrical control box, and screw compressor body, effectively reducing maintenance time. This reduces the workload of maintenance personnel. When the unit is running, the compressed gas generated by the screw compressor body undergoes initial heat exchange and cooling through a horizontal shell and tube heat exchanger. The top fan starts simultaneously to accelerate heat dissipation. The evaporative cooler and the auxiliary air-cooling module work together to perform secondary cooling on the medium after heat exchange, forming a dual cooling structure. Compared with traditional independent air-cooling or water-cooling methods, the heat dissipation margin is sufficient, and the medium temperature can be accurately controlled within the set range. This solves the problems of insufficient heat dissipation and low temperature control accuracy of traditional screw chiller units, ensuring that the unit can operate stably under high load conditions. This invention discloses an integrated screw compressor evaporative cooling unit. During operation, the roof effectively shields the unit from rain and dust, the protective net prevents foreign objects from entering core components such as the evaporative cooler, and the protective mechanism provides comprehensive protection for critical components such as the horizontal shell-and-tube heat exchanger and electrical control box. These three elements work together to prevent damage to the unit components from external factors. Simultaneously, the drainage holes on the mounting base allow for timely drainage of accumulated water, preventing corrosion of the unit components. Auxiliary structures such as crossbeams and positioning components further enhance the overall stability of the unit, reduce vibration during operation, effectively extend the unit's service life, and lower equipment replacement costs. The unit adopts a box-type skid-mounted integrated form, with all components integrated and assembled on the frame and mounting base. This compact structure occupies a small area and can be fixedly installed via the mounting base, facilitating transportation and on-site deployment, and adapting to the needs of different installation scenarios. Furthermore, the screw compressor body adopts a volumetric twin-screw oil-injection structure, ensuring smooth operation and low vibration and noise. Combined with the comprehensive cooling and protection structure, the unit meets the modern enterprise's requirements for efficient, stable, and convenient use of screw compressors.
