Technical Field

[0001] The utility model relates to the technical field of refrigeration units, in particular to an improved refrigeration unit. Background Art

[0002] There is a kind of cooling unit in foreign countries as shown in the instruction manual Figure 4 As shown, the box is rectangular in shape, and the middle of the box is divided into an electrical compartment and a mechanical compartment by a partition. The mechanical compartment contains inverters, controllers, fuses, relays, terminal blocks, and air switches. The mechanical compartment is equipped with three major components, namely, a compressor, a liquid storage tank, and a plate heat exchanger, and other pipes. The compressor, liquid storage tank, and plate heat exchanger are arranged in parallel. The existing cold-carrying unit is relatively large in size, with a length, width, and height of 1200mm, 460mm, and 250mm, occupying a large area and space, and having great limitations in adapting to the site. Utility Model Content

[0003] The purpose of the utility model is to provide an improved refrigeration unit, which divides a square box into a rectangular mechanical compartment and an "L"-shaped electrical compartment by L-shaped plate ribs, and can greatly reduce the occupied area and space of the refrigeration unit by optimizing and reasonably arranging the large-volume components of the refrigeration unit, so that it can be adapted to more usage sites.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] An improved cooling unit comprises a square box body, wherein an L-shaped plate rib is fixed in the square box body, and the L-shaped plate rib separates the square box body into a rectangular mechanical compartment and an L-shaped electrical compartment;

[0006] A compressor, a liquid storage tank and a plate heat exchanger are fixed in the mechanical compartment;

[0007] The electrical compartment is fixed with a frequency converter, a controller, a fuse, a relay, a terminal block group and an air switch.

[0008] Through the above technical solution, the square box is divided into a mechanical compartment and an electrical compartment by L-shaped rib plates instead of the existing mechanical compartment and electrical compartment being arranged side by side on the left and right. This can greatly reduce the volume and occupied space of the square box, making the layout of the cooling unit more compact and reasonable.

[0009] The length, height and width of the square box of this improved refrigeration unit are 700mm, 600mm and 300mm respectively. The unit occupies a flat area of ​​0.42㎡ and a space volume of 0.126 m³, which are much smaller than the existing foreign refrigeration units in terms of occupied area and volume.

[0010] The compressor and the liquid storage tank are cylindrical, the compressor and the liquid storage tank are horizontally placed and arranged in parallel, and the plate heat exchanger is placed on the front side of the liquid storage tank.

[0011] By arranging the compressor and liquid storage tank left and right and the liquid storage tank and plate heat exchanger front and back instead of the existing foreign compressor, liquid storage tank, plate heat exchanger parallel arrangement, the layout rationality of several large mechanical parts of the refrigeration unit in the machinery compartment can be further improved, thereby further reducing the size of the machinery compartment.

[0012] The frequency converter and the air switch are placed in the longitudinal compartment of the electrical compartment, and the controller, the fuse, the relay and the terminal block are placed in the transverse compartment of the electrical compartment.

[0013] Further layout is carried out based on the sizes of several large electrical components, making full use of the horizontal and vertical compartments of the electrical warehouse to further improve the rationality of the layout and reduce the space occupied by each large electrical component.

[0014] The controller is arranged vertically and fixed on the L-shaped plate rib;

[0015] The fuse and relay are arranged up and down and fixed on the L-shaped plate rib, and the fuse and relay are arranged in parallel on one side of the controller;

[0016] The wiring terminal group is fixed on the L-shaped plate rib.

[0017] By arranging the controller, fuse, relay and terminal block vertically, this arrangement can fully take into account the height of the L-shaped plate rib and occupy less space than horizontal arrangement, thereby further reducing the size of the electrical compartment.

[0018] The right-angle end of the L-shaped plate rib is fixedly connected to a side wall of the square box body through a supporting strip.

[0019] The structural stability of the L-shaped plate ribs can be increased by supporting the slats, thereby further ensuring the stability of the electrical compartment and the mechanical compartment.

[0020] The outstanding effects of the utility model are:

[0021] Compared with the existing technology, the square box is divided into a rectangular mechanical compartment and an "L"-shaped electrical compartment by L-shaped plate ribs. By optimizing and reasonably arranging the large-volume components of the refrigeration unit, the occupied area and space of the refrigeration unit can be greatly reduced, and it can be adapted to more usage sites.
