Terminal novel fan of fixed point refrigeration furred ceiling overhauls structure

Technical Field

The utility model relates to a terminal novel fan of fixed point refrigeration furred ceiling overhauls structure belongs to furred ceiling end structure technical field.

Background

With the rapid development of IT technology, the application of high power density rack servers, blade servers, storage servers and small high-power machines is popularized, and the application of high-performance servers leads to the rapid increase of the heat load of a single cabinet. The problems of 'hot spots' and 'hot zones' of a high-heat-density machine room are increasingly prominent due to the fact that single under-floor air supply or air supply on an air duct and the like are difficult to simultaneously consider the upper portion and the lower portion of the cabinet. The fixed-point refrigerating unit can be matched with an air conditioner of a conventional machine room, and the heating problem of 5-30kW of a single machine cabinet is solved. The unit consists of a main machine and a tail end, wherein the main machine for refrigeration is divided into air cooling, water cooling, chilled water and the like, and the tail end is divided into a ceiling, a vertical type and a vertical installation above a cabinet and the like. The fixed-point refrigeration system consists of a direct refrigeration cycle and an indirect refrigeration cycle. The direct refrigeration cycle is that the plate exchange cooling secondary refrigerant returns to the liquid storage device, is conveyed to the refrigeration tail end by the fluorine pump, absorbs the heat discharged by the cabinet, and evaporates and returns to the plate exchange refrigeration cycle; in the indirect refrigeration cycle, a low-temperature refrigerant circulating in the main machine absorbs heat from secondary refrigerant gas at the refrigeration tail end through plate exchange, and then the heat is discharged through the outdoor unit to finish continuous cooling cycle of the secondary refrigerant.

At present, in the maintenance work to the terminal maintenance of furred ceiling, often need the maintainer to tear down the roof earlier, can overhaul or maintain, waste time and energy, work efficiency is low.

Disclosure of Invention

In order to solve the terminal problem of dismantling the roof of maintaining and needing to tear the roof of conventional furred ceiling, the utility model provides a terminal novel fan of fixed point refrigeration furred ceiling overhauls structure, its concrete technical scheme as follows:

a novel fan maintenance structure at the tail end of a fixed-point refrigeration suspended ceiling comprises a frame, a micro-channel heat exchanger arranged in the frame, an electrical appliance box, an electronic expansion valve, a pipeline, a controller and a fan penetrating the bottom of the frame,

the electric appliance box is arranged on the inner wall of the frame in a fitting manner, the pipeline is arranged on the opposite side of the electric appliance box, the pipeline and the electric appliance box are designed on two sides, the pipeline and the circuit are ensured not to be crossed, the maintenance is convenient,

the fan is provided with a wind guide ring mounting plate capable of driving the fan to rotate, one side of the wind guide ring mounting plate is rotatably connected with the frame, and four corners of the wind guide ring mounting plate are fixedly connected with the frame through fixing screws.

Furthermore, the wind-guiding circle mounting panel is through wearing two M8 screws and frame swivelling joint, and in the maintenance process of overhauing, only need loosen two M8 screws a little, lift off four fixed screws from the bottom again, can make the fan rotate 90 downwards, and the inner space is enough to let the maintainer health get into, and operates.

Furthermore, one end of the wind guide ring mounting plate, which is rotatably connected with the fan, is bent in multiple ways and is fully welded, and then is polished to be flat.

Further, in order to facilitate maintenance, the controller is arranged at the bottom of the frame, and the air guide ring mounting plate is provided with the avoiding hole of the controller, so that the controller is fixed in the frame and does not move in the downward rotation process of the fan, and the air guide ring mounting plate is not interfered with the frame.

The utility model has the advantages that:

the utility model provides a terminal maintenance of conventional furred ceiling need tear the problem of roof open, adopt rotatable fan structure, and the maintainer utilizes the space after the fan is unscrewed, can get into the unit inside very conveniently and maintain, has practiced thrift the time and the energy of on-the-spot solution unit trouble effectively, improves the work efficiency of overhauing and maintaining.

The design scheme of the utility model, structurally not complicated, only have certain requirement to the panel beating welding on, have characteristics such as simple structure, with low costs, installation maintenance convenience, design compact structure.
