You will need to keep the fin heat exchanger clean every once in a while. You will find that you are able to keep it clean and take care of it with proper maintenance and cleaning, the longer it will make it last longer, which will be the better job. Step 1 Open The first thing you will do is open the lid of the  air cooler . Due to the cooling process of the air cooler, fresh air from outside circulates throughout the office or home. Every air cooler is different, so unless you have to open it before, you may need to look at the instructions and check to see exactly how to do it. Improper doing so may cause damage to your evaporative air conditioner. Step 2 Check The air in your room will never be out of date. This even allows you to enjoy a free operating unit, even if the doors and windows are open. After the cooler has been turned on, it is a good idea to take the pad and double check. If they want to be in good condition without debris or molds, then they will have to be repla...

Finned tubes  are widely used in power, chemical and other industries. Many spiral heat transfer surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat exchange area and promoting turbulence, and it has a great effect on both single-phase-convection heat transfer and phase-change convective heat transfer. The structure of the finned tube heat exchanger is basically the same as the general shell and tube heat exchanger. Just use finned tubes instead of light tubes as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc. The finned tube has a wide range of materials, including stainless steel, carbon steel, titanium-copper alloy, etc. The corrosion resistance of the industry has greatly increased.

Murphy  heat exchanger is designed to provide maximum efficiency in transferring heat from one liquid to another or from steam to liquid. It consists of a series of gasketed, embossed metal plates arranged alternately and bolted together between end frames to form channels through which hot and cold media flow. The hot fluid flows on one side of the plate while the cold fluid flows on the other, with the plate itself providing the most effective means to transfer heat from one fluid to the other. Gaskets on the plates seal the channels and provide flow direction. As liquids flow counter-currently through the channels between the plates, the cold liquid becomes warmer and the hot liquid cooler.  www.murphyfinnedtubes.com Most units are designed for a one-pass/one-pass flow arrangement, resulting in all nozzles being installed on the stationary end frame, which facilitates simpler piping arrangements and easier disassembly. Due to its high efficiency, the Murphy ...

Working principle: The plate heat exchanger is composed of a set of corrugated metal plates with four corner holes for the passage of two liquids for heat transfer. The metal sheet is mounted in a frame having a fixed plate and a movable pressing plate on one side and clamped by a clamp bolt. A gasket is placed over the plate to seal the fluid passages and direct fluid flow alternately into the respective passages to form a heat exchange. The flow, physical properties, pressure drop and temperature difference of the fluid determine the number and size of the plates. The corrugation of the plate not only increases the degree of turbulence but also forms a number of support points sufficient to withstand the pressure difference between the media. The metal plate and the movable compression plate are suspended on the upper guide bar and positioned by the lower guide bar, while the rod end is fixed on the support. On the column, but if one or both of the liquids pass through the heat ...
