Description

Interlayer cooling cabinet

Technical Field

The utility model relates to an industry rack, especially an intermediate layer refrigerated rack for IT and electronic equipment.

Background

With the rapid development of electronic technology, the integration level of electronic devices is higher and higher, and the total heat generation amount and the heat generation density per unit volume are also higher and higher. Especially in the IT and electronics field, the heat generation of the equipment inside a cabinet can reach or even exceed 50 KW. Such as IT cabinets for servers and network equipment and electronic cabinets with electronic bays mounted therein. According to the formed industry standard, the installation mode of the internal equipment of the two cabinets is front-back plugging, the heat dissipation mode is that cold air enters the equipment from the front of the equipment, and hot air is discharged from the rear of the equipment. In large-scale applications, such as IDC rooms, the IT and electronic cabinets that have air flowing in and out are usually designed to suck cold air from the front through an indoor environment or a specially constructed cold channel, and then discharge the hot air from the rear into the indoor environment or a specially constructed hot channel. There are also small and medium sized applications where an IT cabinet or an electronics cabinet is flanked by a cooling unit as disclosed in chinese patent 201020602950.9. At this time, the cabinet and the cooling unit are closed to the outside and the inside is communicated. The flow process of the internal air flow and heat is as follows: hot air at the rear part of the cabinet enters the rear part of the cooling unit, becomes cold air through the heat exchanger at the middle part of the cooling unit, enters the front part of the cabinet from the front part of the cooling unit, and the cold air at the front part of the cabinet passes through the inside of equipment to take away the heat inside the equipment and then sends the hot air to the rear part of the cabinet. In short, the air flow and heat flow inside the IT cabinet and the electronic cabinet are both in the horizontal direction, and the equipment inside the cabinet and at different heights can be uniformly cooled by the shortest air flow path.

For some small-sized applications, the total heat productivity inside an IT cabinet or an electronic cabinet is 2-4KW, the temperature, humidity and cleanliness of the external environment cannot meet the requirements, and the cabinet must be closed. Side mounted cooling units increase cost and take up more space. Therefore, a need exists for a sealed cabinet with better heat dissipation capabilities.

arrows

18, 19, 20, 21, 22 and 23 indicating the airflow direction, the hot air at the rear part of the cabinet enters the rear parts of the interlayers at the left and right sides under the suction effect of the rear fan 11, passes through the ventilation openings 16 on the air partition plate 15 after being cooled by the heat exchanger 12, enters the front parts of the interlayers at the left and right sides, and enters the cabinet under the blowing effect of the front fan 17 to become cold air at the front part of the cabinet; the cold air absorbs the heat in the cabinet to reach the rear part of the cabinet and then becomes hot air at the rear part of the cabinet;

specifically, the rear fans 11 on both sides of the cabinet suck the hot air at the rear of the cabinet in the direction indicated by the arrow 18 indicating the direction of airflow to the rear of the interlayer formed by the outer panel 2 and the rear fan mounting panel 7, the inner panel 9 and the front fan mounting panel 10 on both sides of the cabinet, then the hot air passes through the heat exchanger 12 in the direction indicated by the arrow 19 indicating the direction of airflow to become cold air, then passes through the vents 16 on the air barrier 15, the cold air reaches the front of the interlayer formed by the outer panel 2 and the rear fan mounting panel 7, the inner panel 9 and the front fan mounting panel 10 on both sides of the cabinet, the front fans 17 blow the cold air into the inside of the cabinet in the direction indicated by the arrow 20 indicating the direction of airflow and reaches the front of the cabinet in the direction indicated by the arrow 21 indicating the direction of airflow, and the cold air at the front of the cabinet passes through the inside of the cabinet in the direction indicated by the arrow 22 indicating the direction of airflow to become hot air in the direction indicated by the arrow 23 indicating the direction of airflow to reach the rear of the cabinet Circulating in this way, the heat inside the cabinet is absorbed by the cooling medium inside the exchanger 12 and taken outside the cabinet.

Example 2

Fig. 2 is another embodiment of the present invention in various embodiments of a cabinet with a cooling jacket. The rear door 1, the outer side plate 2, the front door 3, the top cover 4, the bottom plate 5, the frame 6 and the angle gauge 8 are all basic configurations of an IT cabinet and an electronic cabinet standard, and form a common IT cabinet or electronic cabinet with the height of 1600 mm. When the cabinet needs to be sealed and has heat dissipation requirements, three rear fan mounting plates 7, an inner side plate 9 and four front fan mounting plates 10 are respectively added on two sides of the utility model, and form a front and back ventilation interlayer together with each outer side plate 2; the interiors of the interlayers at the two sides are symmetrically distributed; each wind-shield plate 15 and each heat exchanger 12 divide an interlayer into a front part and a rear part, and the air of the front part and the rear part is communicated with the ventilation opening 16 on the wind-shield plate 15 through the clearance between the heat exchange fins of the heat exchanger 12;
