Description

Technical Field

[0001] The utility model relates to the technical field of electric control box cooling, in particular to a high-efficiency cooling device for an electric control box. Background Art

[0002] In current commercial refrigeration and freezing industry projects, electrical components in the electrical control boxes used by compressors, condensers, evaporators and other equipment will emit heat when working. If this heat cannot be discharged in time, the heat will accumulate in the electrical box over time, causing aging of components and wires and cables, and reduction in component capacity and cable current carrying capacity, leading to safety accidents. Therefore, necessary ventilation and heat reduction measures must be taken for the electrical box.

[0003] The traditional form is to use cooling fans or water cooling: 1. Ordinary cooling fans have no obvious cooling effect on components with large heat generation; 2. Water cooling requires water circulation, which requires additional water channels to dissipate heat, and ensures the insulation level of the water system and electrical components. The equipment cost is high and the safety requirements are high. The above traditional methods of achieving heat exchange between the outside world and the electrical box are inefficient. In the field of commercial refrigeration and freezing, the electrical box and control cabinet are in the same computer room as compressors, water pumps and other equipment with large heat dissipation. The electrical box is in a high temperature environment for a long time, and the heat exchange efficiency between the electrical box and the outside world will be lower. Although the installation of air conditioning and ventilation systems in the computer room can solve this problem, the installation cost and later energy consumption are high. Based on the above pain points, and combined with the characteristics of the refrigeration and freezing industry, a low-cost and efficient cooling device for electrical control boxes is introduced. Utility Model Content

[0004] The purpose of the utility model is to provide an efficient cooling device for an electric control box to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient cooling device for an electric control box, comprising a compressor room, a condenser arranged outdoors, and a terminal evaporator device arranged on one side of the compressor room, wherein a refrigeration cycle component is arranged between the compressor room, the condenser and the terminal evaporator device.

[0006] Preferably, the refrigeration cycle components include: an electrical control box, arranged inside the compressor room; a liquid storage tank, arranged inside the compressor room; a compressor unit, arranged inside the compressor room; and a terminal evaporator device, arranged on the end customer side away from the compressor room.

[0007] Preferably, the electric control box is equipped with an evaporator, an expansion valve and a fan. A liquid supply branch is taken from the compressor unit to the electric control box, which is equipped with an evaporator, an expansion valve and a fan. The air cooled by the evaporator circulates in the heat dissipation duct to take away the heat emitted by the components.

[0008] Preferably, the liquid storage tank is connected to the terminal evaporator device through a terminal expansion valve pipeline, and a terminal expansion valve is provided on the terminal expansion valve pipeline. Liquid refrigerant is supplied from the liquid storage tank to the terminal evaporator device along the pipeline, and refrigerated through the terminal expansion valve throttling device. The liquid refrigerant evaporates from liquid to gaseous state, taking away heat, and realizing refrigeration of the terminal device, i.e., the cold storage evaporator, the freezer evaporator, and the ice maker.

[0009] Preferably, the liquid storage tank is connected to the compressor unit through a pipeline; the compressor unit is connected to the condenser through a pipeline; the condenser is connected to the liquid storage tank through a pipeline. After the gaseous refrigerant is recovered and compressed by the compressor unit, it is fed to the outdoor condenser, and the high-temperature gas is liquefied and recovered to the liquid storage tank in the machine room to realize the cooling cycle.

[0010] Preferably, the terminal evaporator equipment includes a cold storage evaporator, a freezer evaporator, and an ice maker.

[0011] The utility model provides a high-efficiency cooling device for an electric control box, which has the following beneficial effects:

[0012] (1) The utility model supplies liquid refrigerant from a liquid storage tank to a terminal evaporator device along a pipeline, and refrigerates the device through a terminal expansion valve throttling device. The liquid refrigerant evaporates from a liquid state to a gas state, taking away heat, thereby achieving refrigeration of the terminal device, i.e., a cold storage evaporator, a refrigerator evaporator, and an ice maker; the gaseous refrigerant is recovered and compressed by a compressor unit and then supplied to an outdoor condenser, where the high-temperature gas is liquefied and recovered to the liquid storage tank in the machine room, thereby achieving a cooling cycle and achieving a circulating cooling effect.

[0013] (2) The utility model combines the characteristics of the commercial refrigeration industry with the original refrigeration cycle equipment to bring efficient cooling effect to the electric control box on the basis of relatively small investment and energy consumption, and can be widely used in new projects or renovation projects in the commercial refrigeration industry.

[0014] (3) The utility model takes a liquid supply branch from the compressor unit to the electric control box, which is equipped with an evaporator, an expansion valve and a fan. The air cooled by the evaporator circulates in the heat dissipation duct to take away the heat emitted by the components, thus avoiding the traditional heat dissipation of the electric box, which only uses ventilation such as fans to achieve heat exchange between the outside and the electric box, and has low efficiency.
