Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, and particularly relates to a new type of screw water chiller. Background Art

[0002] A screw water chiller is a water chiller with various forms of screw compressors as the main unit. It is an assembled refrigeration device composed of a screw refrigeration compressor, a condenser, an evaporator, a thermal expansion valve, an oil separator, and automatic control components and instruments.

[0003] A water chiller is a refrigeration device used to cool water to a certain temperature and recycle it. Its working principle is as follows: The refrigerating machine compresses the refrigerant into a liquid state through a compressor and then sends it to the evaporator for heat exchange with the chilled water, refrigerating the chilled water. The chilled water pump sends the chilled water to the cooling coils at the air outlets of each fan, and the fan blows to achieve the purpose of cooling. The refrigerant after evaporation releases heat in the condenser and becomes gaseous. The cooling water pump sends the cooling water to the cooling tower, and the water tower fan sprays and cools it to conduct heat exchange with the atmosphere and dissipate the heat into the atmosphere.

[0004] In the Chinese utility model patent with the publication number CN220453970U, a flooded screw chiller is disclosed, which includes a condenser, a flooded evaporator, a screw compressor, a control box, a first support frame, and a second support frame. The condenser and the flooded evaporator are both installed between the first support frame and the second support frame. The screw compressor and the control box are both arranged above the flooded evaporator. The condenser and the flooded evaporator are both provided with a water outlet pipe and a water inlet pipe. The water outlet pipe and the water inlet pipe are both arranged on the side of the flooded evaporator close to the first support frame. One ends of the water outlet pipe and the water inlet pipe far from the second support frame are both provided with connecting flanges. The connecting flanges are provided with guide blocks and connecting sleeves. The guide blocks are arranged on the outer surface of the connecting flanges. The connecting sleeves are connected to the guide blocks through grooves. The condenser, the flooded evaporator, and the screw compressor are all electrically connected through the control box.

[0005] Regarding the above related technologies, the inventor believes that there are the following defects: The condenser, the evaporator, and the screw compressor are all installed between the first support frame and the second support frame, and the structures between them are compact. The condenser, the evaporator, and the screw compressor will all generate heat during operation. The arrangement method in the above technologies is not conducive to the heat dissipation of the condenser, the evaporator, and the screw compressor. Therefore, it is necessary to improve and design the related technologies. Content of the Utility Model

[0006] In order to solve the above problems, the utility model provides a new type of screw water chiller.

[0007] The above technical object of the utility model is achieved by the following technical solutions: A new type of screw water chiller, including a base, and a mounting frame fixed on the top of the base. A condenser is arranged on the bottom crossbar of the mounting frame, an evaporator is arranged on the middle crossbar of the mounting frame, a screw compressor is arranged on the top of the mounting frame, a control box is arranged on one side of the mounting frame, and the condenser, the evaporator and the screw compressor are all electrically connected to the control box.

[0008] By adopting the above technical solutions, the condenser, the evaporator and the screw compressor are arranged in layers and are independent of each other, having a certain heat dissipation space, reducing the probability that the heat generated between them affects each other and is not conducive to the heat dissipation of the water chiller, and is beneficial to ensuring the normal operation of the water chiller.

[0009] Further, the condenser and the evaporator are parallel to each other and are staggeredly distributed, and the axis of the screw compressor is perpendicular to the axis of the condenser.

[0010] By adopting the above technical solutions, the condenser, the evaporator and the screw compressor are staggeredly distributed in layers, further reducing the probability that the heat generated between them affects each other during the working process and is not conducive to the heat dissipation of the equipment.

[0011] Further, a plurality of cushion blocks distributed in a rectangular array are fixed at the bottom of the base, a protective shell is fixed on the top of the base, the mounting frame, the condenser, the evaporator, the screw compressor and the control box are all located inside the protective shell, and a plurality of control switches electrically connected to the control box and used for controlling the condenser, the evaporator or the screw compressor are arranged on the protective shell.

[0012] By adopting the above technical solutions, the setting of the protective shell plays a good protective role, reducing the probability that others accidentally touch the relatively hot condenser, evaporator or screw compressor and get into danger.

[0013] Further, a plurality of detachable side plates and breathable mesh plates are arranged on the protective shell.

[0014] By adopting the above technical solutions, the setting of the side plates facilitates the installation or maintenance of the components of the screw water chiller by the staff, and the setting of the breathable mesh plates ensures the heat dissipation during the working process of the water chiller.

[0015] Further, a mounting cylinder is fixed on the top of the protective shell, an air inlet is opened at the position corresponding to the mounting cylinder on the top of the protective shell, a mounting rod is fixed on the inner wall of the mounting cylinder, a motor is fixed on the mounting rod, and a heat dissipation blade is fixed on the output end of the motor.

[0016] By adopting the above technical solution, after the motor works, it drives the cooling fins to rotate, thereby blowing air into the protective housing, so that an air convection cycle is formed between the inside and the outside of the protective housing, which is beneficial to accelerating the heat dissipation of the chiller.

[0017] Furthermore, a plurality of convection openings are provided at the bottom of the base.

[0018] In summary, the present utility model has the following beneficial effects:

[0019] 1. In this application, the condenser, the evaporator and the screw compressor are arranged in layers and are independent of each other, having a certain heat dissipation space, reducing the probability that the heat generated between them affects each other and is not conducive to the heat dissipation of the chiller, and is beneficial to ensuring the normal operation of the chiller;

[0027] The condenser 3, the evaporator 4 and the screw compressor 5 are arranged in layers and are independent of each other, having a certain heat dissipation space, reducing the probability that the heat generated between them affects each other and is not conducive to the heat dissipation of the water chiller, and is conducive to ensuring the normal operation of the water chiller.
