A new type of air-cooled box-type water chiller unit

Abstract

This utility model discloses a novel air-cooled box-type chiller unit, relating to the field of chiller technology. It includes a chiller casing with a cooling fan at the top and ventilation windows on the outer side. The novel air-cooled box-type chiller unit incorporates a cleaning component on the outer side of the filter screen. During filter cleaning, the control panel controls the outputs of two drive motors to rotate a threaded rod along the inside of a threaded seat, thereby driving a support frame and cleaning brush to clean the filter screen along its inner and outer sides. The suction motor is activated, drawing dust into the suction pipe from the suction head, then through a three-way pipe into the connecting box, and finally through the exhaust pipe, discharging the dust away from the filter screen. This prevents dust from re-entering the filter screen during chiller cooling, further improving heat dissipation efficiency.

Technical Field

[0001] This utility model relates to the field of chiller technology, and in particular to a novel air-cooled box-type chiller unit. Background Technology

[0002] A chiller is a water-cooling device that provides cooling water at constant temperature, constant flow, and constant pressure. It is widely used in air conditioning systems, industrial cooling, and various other applications requiring cooling. There are many types of chillers, including air-cooled box-type chillers, which are refrigeration devices that provide chilled water. They use air cooling to dissipate heat without the need for additional cooling media, making installation and maintenance more convenient.

[0003] Existing air-cooled box-type chillers are equipped with filters to prevent external dust from entering the machine through the heat dissipation windows. However, these filters are prone to clogging after prolonged use, which affects heat dissipation efficiency. They also require manual cleaning, which is time-consuming and labor-intensive, thus impacting the efficiency of air-cooled heat dissipation in the chiller casing. Therefore, this utility model proposes a novel air-cooled box-type chiller unit. Utility Model Content

[0009] As a further technical solution of this utility model, the number of drive motors is two sets and they are symmetrically distributed. The drive motors are connected to the chiller box by bolts. The number of sliding holes is two sets and they are symmetrically distributed. The output end of the drive motor is fixedly connected to the threaded rod. A bearing seat is provided at the connection between the threaded rod and the sliding hole.

[0013] Beneficial effects:

[0014] This design introduces a novel air-cooled box-type chiller unit. By installing a cleaning component on the outside of the filter screen, during the filter cleaning process, the control panel controls the output ends of two sets of drive motors to rotate the threaded rod along the inside of the threaded seat. This, in turn, drives the support frame and cleaning brush to clean the filter screen along both the inside and outside. The suction motor is activated, and dust enters the suction pipe from the suction head, then flows through the T-connector into the connecting box, and finally is exhausted through the exhaust pipe, discharging the dust away from the filter screen. This prevents dust from re-entering the filter screen during the chiller's cooling process, further improving heat dissipation efficiency. Attached Figure Description

The heat dissipation window and the filter screen 3 are connected by bolts. A control panel is installed on the outside of the chiller casing 1. The control panel has control buttons and a display screen on the outside. The control panel has a control circuit board and a battery inside, which facilitates the control of the cleaning component 4 to clean the filter screen 3.

[0024] like Figure 2-4 As shown, there are two sets of drive motors 41, which are symmetrically distributed. The drive motors 41 are connected to the chiller casing 1 by bolts.
