Description

Technical Field

[0001] This utility model relates to the manufacturing technology of refrigerator refrigeration components, and in particular to a PCM microcapsule encapsulation spraying and drying device for refrigerator condensers. Background Technology

[0002] The refrigerator condenser is a device that dissipates the heat from the high-pressure, high-temperature refrigerant gas delivered by the compressor to the outside space of the refrigerator. After being cooled by heat dissipation, the refrigerant gas liquefies, becoming a high-pressure, room-temperature refrigerant liquid. It is one of the important components of the refrigeration system. Phase change materials are a class of materials that can absorb, store, or release large amounts of heat within a specific temperature range. In refrigerators, they serve as heat energy storage media, absorbing and releasing heat to assist the refrigeration cycle, improving energy efficiency and temperature control stability.

[0003] Microencapsulation technology encapsulates PCM (phase change materials) within tiny capsules, forming a core-shell structure. This encapsulation effectively prevents PCM leakage, improving its performance and reliability in thermal energy storage and thermal management systems. Currently, while various processing methods exist for microencapsulation technology used in the refrigerator industry, they all require assembly line operations involving changes in workstations. This not only results in a large workload and extended product manufacturing time but also increases the risk of coating peeling during workstation changes, affecting product quality. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a PCM microcapsule encapsulation spraying and drying device for refrigerator condensers. It features simple operation, automatic control, no need to change workstations, and completion of the entire PCM microcapsule encapsulation spraying operation in one clamping.

[0006] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spray drying device, preferably, the tank is provided with a door that is hinged to the tank, and a proximity sensor is provided at the mating part between the door and the tank.

[0007] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spray drying device, preferably, a spray-stopping shielding mechanism is provided in conjunction with the spray nozzle. The spray-stopping shielding mechanism is provided with a shielding plate larger than the nozzle opening area of ​​the spray nozzle, and the shielding plate is driven by a rotating shaft.

[0008] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spray drying device, preferably, the nozzle and the anti-spray shielding mechanism are positioned on a servo guide rail, and the nozzle and the anti-spray shielding mechanism are adjustable in position along the guide rail.

[0009] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spraying and drying device, preferably, the tank is provided with a transparent observation window, the position of which is adapted to the position of the condenser to be sprayed suspended by the rotating disc.

[0010] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spray drying device, preferably, the dryer is an infrared dryer, an electromagnetic dryer, or a hot air dryer.

[0011] In the aforementioned refrigerator condenser PCM microcapsule encapsulation spray drying device, preferably, the rotating disk has a hollow or mesh structure, and at least two hooks are provided on the rotating disk, and the hooks are rigidly connected to the rotating disk and the condenser.

[0012] This technical solution addresses the problems of traditional PCM materials in practical applications, such as easy leakage, volume change, phase separation, and corrosion. It designs an integrated spraying and drying device, which not only improves the performance and reliability of PCM materials in thermal energy storage and thermal management systems by microencapsulating them, but also solves the risks of environmental pollution and equipment damage caused by PCM leakage due to product transfer, process complexity, and other reasons.

[0013] This device utilizes a rotating disk at a constant speed and controllable parameters such as rotation speed and spray volume to prepare uniformly distributed microcapsules, thereby enhancing the heat exchange efficiency and temperature control stability of refrigerator condensers, evaporators, and other products, reducing energy consumption, and improving the overall energy efficiency of the refrigerator.

[0014] The bottom of the tank is equipped with a collection tray to recycle the dropped PCM solution, saving materials. It is equipped with a spray stop and shielding mechanism in conjunction with the nozzle to prevent the sprayed PCM solution from affecting the operator or workpiece during pauses, adjustments or preparations. At the same time, it can block the dryer from directly irradiating the nozzle when the spraying is stopped, preventing the nozzle from clogging.

[0015] The servo guide rail design allows for adjustment of the nozzle height and also enables vertical movement during the spraying process, satisfying the spraying requirements of the workpiece in the height direction and the spraying of products of different heights.

[0016] In this device, the rotating disc has a hollow or grid frame structure to ensure that it does not obstruct the operation of the dryer.

In the rotating state, it does not affect the infrared drying and the fan blowing towards the workpiece to be sprayed. The rotating disk 9 is provided with at least two hooks, and the hooks are rigidly connected to the rotating disk 9 and the condenser 14 of the workpiece to be sprayed, that is, they cannot rotate with each other.

[0026] A nozzle 5 is positioned horizontally opposite the condenser 14 of the workpiece to be coated on the tank 1. A spray-stopping mechanism is also provided in conjunction with the nozzle 5. This mechanism includes a shielding plate 12 larger than the nozzle opening area. The shielding plate 12 is made of heat-insulating material, and the side facing the nozzle 5 is a smooth mirror surface. The shielding plate 12 is driven by a rotating shaft 7. Both the nozzle 5 and the spray-stopping mechanism are fixed to a servo guide rail 6. The servo guide rail 6 includes two vertically arranged rails. The nozzle 5 and the spray-stopping mechanism engage with the two rails via a slider. A linear motor is installed inside the slider, allowing the nozzle 5 and the spray-stopping mechanism to be adjusted and movable vertically along the guide rails. Limit switches are provided at both the top and bottom of the two rails.

[0027] The bottom of tank 1 is equipped with a collection tray 2, the bottom of which is conical to facilitate the collection of PCM solution. The bottom of the collection tray 2 is connected to a mixing tank 3 located outside tank 1 via a pipe. The mixing tank 3 is equipped with a pressure pump 4, which is connected to a nozzle 5 via a pipe. The mixing tank 3 is also equipped with a liquid inlet to replenish PCM solution and a level gauge.

[0028] The tank body 1 is also provided with a transparent observation window 8, the position of which is adapted to the position of the condenser 14 of the part to be sprayed suspended by the rotating disk 9.

[0029] This embodiment uses direct current and the control circuit is a conventional circuit, such as... Figure 3 As shown, it includes two proximity sensors on the door 11, a rotary motor that drives the rotating disk 9, a heating source for the dryer 10 at the top of the tank 1, a servo guide rail 6, and a pressure pump 3, etc.
