Counter Top Cooler can be mainly divided into three types: tube type, corrugated plate type and air-cooled type. Among them, the tube-and-tube heat exchanger can be divided into double tube type, vertical type, horizontal type, floating head type, etc. The characteristic of the tube-and-tube heat exchanger is that the water used for cooling flows through the inside of the tube, while the oil is Flowing through the distance of the tube, the centrally arranged folding plate allows the oil to baffle, and the two-way or even four-way movement method it uses makes its cooling effect more intense; the corrugated plate heat exchanger can also be divided into herringbone and oblique corrugation It mainly uses the contact points placed in the corrugated structure, which allows the fluid to form turbulent flow when the flow rate is not high, which greatly improves the heat dissipation effect; the air-cooled heat exchanger can be divided into direct type and fixed type. It has the characteristics of simple structure, small size, light weight and convenient use. Next, we will take the tubular heat exchanger as an example to explain the working principle of the heat exchanger.
The tubular Counter Top Cooler is mainly composed of two parts: the outer shell and the inner heat exchanger body. The outer shell includes a cylinder, a water divider cover and a water return cover. There are oil inlet pipes, oil outlet pipes, water inlet pipes, and water outlet pipes, and are attached with oil drain, drain, exhaust screw plugs, and zinc rod device holes. Thermometer interface, etc. The heat exchanger body includes heat exchanger tubes, fixed orifice disks, movable orifice disks, baffles, etc. The two ends of the heat exchanger tube are connected with the fixed and movable orifice disks, and the fixed orifice disk is connected with the outer body flange. The movable orifice disk can be freely elastic in the outer body to eliminate the influence of temperature on the heat exchanger tube due to thermal expansion and contraction. . The baffle can enhance the heat transfer and support the heat exchanger tube.
The heat medium of the tube-and-tube Counter Top Cooler flows from the receiving inlet on the cylinder to the receiving outlet in a zigzag manner through the baffle channels. The heat exchanger medium adopts double-pipe-pass activity, that is, the heat exchanger medium enters half of the heat exchanger tubes from the water inlet through the water divider cover, and then flows from the return water cover into the other half of the heat exchanger tubes, and enters the other side of the branch. Water cover and outlet pipe. In the process of double-pipe pass flow of the cold medium, the waste heat released by the absorbing heat medium is discharged from the water outlet, so that the working medium maintains the rated working temperature.
