Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation and cooling, and specifically relates to a cooling and heat dissipation system structure with isolated cooling water, a circulating air path and electrical components. Background Art

[0002] At present, the methods used to solve the on-site operating environment of the inverter include direct exhaust, indoor air conditioning, air-water cooling, water source unit heat dissipation, pure water cooling, etc. Among them, direct exhaust and indoor air conditioning are rarely used, and air-water cooling, water source unit, pure water cooling, etc. are mainly used. Pure water cooling passes cooling water into the power devices of the inverter cabinet unit to achieve the effect of heat exchange with the power devices to cool the power devices. However, leakage of the internal circulation pipes and connectors that transport cooling water can easily cause major failures, which greatly threatens the operating safety of electrical equipment.

[0003] The air-water cooling and water source units use air ducts to connect the hot air from the inverter cabinet to the equipment for cooling. The treated cold air is blown out from the equipment outlet and sent back to the room for cooling. The on-site cooling water is sent to the air-water cooling radiator or the condenser of the water source unit for cooling and heat exchange, and the outlet water is sent to the on-site cooling water tower for cooling.

[0004] The air-to-water-cooled radiator and the condenser of the water source unit that are supplied with cooling water are in contact with the circulating air duct and are not isolated. The heat exchange tubes and connectors that are in contact with the cooling water leak. The circulating air duct is in contact with water and will carry some cooling water into the electrical room. On the other hand, the air-to-water-cooled radiator and the condenser of the water source unit that are supplied with cooling water are at risk of leakage. Based on the above, if the cooling water comes into contact with the electrical components of the cooling equipment, an electrical accident will occur, affecting the operation of the cooling equipment and the inverter, causing a safety hazard. Utility Model Content

[0005] The utility model aims to provide a cooling and heat dissipation system structure with cooling water, circulating air path and electrical components isolated, so as to solve the technical problems existing in the prior art.

[0008] Furthermore, the cooling unit shell is a water source unit shell, the hot air chamber and the cold air circulation chamber are isolated by a vertical plate, and the hot air chamber and the condenser chamber are isolated by a combined partition.

[0009] Furthermore, the combined partition includes a first transverse partition having one end connected to the left end of the water source unit shell and located on the upper part of the control box protection structure, a second transverse partition having one end connected to the vertical plate, and an inclined partition connecting the first transverse partition and the second transverse partition.

[0010] Furthermore, the oblique partition is provided with a through hole for the pipeline to pass through.

[0011] Furthermore, it also includes an auxiliary drainage structure located in front of the cold air circulation chamber and connected to the drainage pan.

[0012] In another embodiment, the cooling unit shell is an air-water cooling unit, the hot air chamber and the cold air circulation chamber are isolated by a frame-type partition, and the cold air circulation chamber and the condenser chamber are isolated by a partition-type partition.

[0013] Furthermore, the partition-type partition includes a first partition, a second partition and a third partition that are horizontally arranged, and there is a gap between the first partition and the second partition, and there is a gap between the second partition and the third partition.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

The hot air inlet is connected to the hot air chamber, and the condenser chamber is located at the lower part of the hot air chamber.

[0032] The isolation structure of the hot air chamber, the condenser chamber and the cold air circulation chamber is as follows: the hot air chamber and the cold air circulation chamber are isolated by a vertical plate, and the hot air chamber and the condenser chamber are isolated by a combined partition, wherein the combined partition includes a first transverse partition having one end connected to the left end of the water source unit shell and located on the upper part of the control box protection structure, a second transverse partition having one end connected to the vertical plate, and an oblique partition connecting the first transverse partition and the second transverse partition, wherein the first transverse partition is located above the second transverse partition; further, a through hole for the pipeline to pass through is provided on the oblique partition; in a further preferred embodiment, the control box protection structure adopts sealed protection, and its physical structure adopts a box structure, and the control box is placed in the control box protection structure.

Before the cooled cold air enters the cold air chamber, the cold air and cooling water are separated at the countercurrent waterproof louvers to prevent cooling water from following the cold air into the electrical room and affecting the operation of electrical components.

[0034] In this embodiment, a drain pan is provided at the bottom of the water source unit shell, a part of the drain pan is located below the condenser chamber, and the other part is located below the cold air circulation chamber, and a drainage structure for guiding the leaked cooling water to the drain pan is provided in the condenser chamber; on this basis, in this embodiment, an auxiliary drainage structure is also provided in front of the cold air circulation chamber, and both the drainage structure and the auxiliary drainage structure can adopt a water diversion pipe structure, wherein the drainage structure is used to guide the cooling water leaked in the condenser chamber to the drain pan, and the auxiliary drainage structure is used to guide the cooling water at the separation point of the countercurrent waterproof louver to the drain pan, and then discharged to the outside of the unit through the drain pan.
