Description

STATIC MPE CONDENSER

TECHNICAL FIELD

The present invention relates to static MPE condenser allowing for discharging the heat in the cooling room, that is used for house, store and industrial types of refrigerators and refrigerating systems.

The present invention relates to particularly static MPE condenser comprising a flat pipe and/or wide contact surface allowing shorter components to be used by contacting to side surface of the refrigerator in a wider area and ensuring more heat transfer.

STATE OF THE ART

A refrigerating cycle is the cycle carried out in a refrigerator, wherein changes resulting from that a refrigerant absorbs the heat and then emits it are defined.

Condenser is a device that allows the refrigeration vapor, of which pressure and temperature are increased by being compressed by a compressor in the refrigerating cycle to release heat to outside and thus the vapor to condense. Said device is also known as condenser.

The refrigeration process in refrigerating systems are carried out by condensing the refrigerating material after it is input as gas and emits its heat to medium.

It is facilitated that the condenser discharges the heat to air by way of increasing the number of the bends of flat pipes and thus, it ensured that the refrigerating material is turned to over-refrigerated liquid state. Cycle is a process, wherein a refrigerant at the low pressure is increased to the high pressure by the compressor and conveyed to condenser therefrom. Condensation is performed in the condenser and the refrigerant going through an expansion valve is brought in a low-pressure liquid state. Afterwards, refrigeration is carried out by means of an evaporator.

In application, storage volume or living environment is refrigerated by means of pumping the source with a lower temperature to the environment with a higher temperature. The heat normally exhibits an opposite direction under normal circumstances (higher temperature to lower temperature). In application, Insulation is of importance. Therefore, insulating materials with a low-heat transmission coefficient are employed. Insulating materials used nowadays are polyurethane. Insulation is necessary to reduce both energy and power required to maintain the lower temperature in the refrigerated medium and to reach down to the lower temperature.

In the present application, particularly in refrigerators and refrigerating systems, serpentine with steel pipe is used as a condenser. Condenser in the form of said serpentine allows the heat to spread at side portion of the refrigerator by contacting with metal sheet at the side surface of refrigerators. In the current case, condensers are formed in the round profile shape. Serpentine makes a linear contact with side metal sheet of the refrigerator and the heat transfer is ensured in this narrow spot. In this way, since the heat transfer spot is insufficient, it is necessary to use longer lengths of steel pipe. In static condensers in present applications, use of round profile pipes and therefore, insufficiency of the heat transfer surface contacting to side metal sheets of the refrigerator causes such applications to be inefficient.

In conclusion, the need for a novel, economical, useful static MPE condenser and insufficiency of the present solutions necessitate development in the related technical field so as to overcome the above-mentioned problems in the state of art. OBJECT OF THE INVENTION

The present invention relates to static MPE condenser allowing for discharging the heat in the cooling room, that is used for house, store and industrial types of refrigerators and refrigerating systems, which aims to bring solution to the above- mentioned drawbacks taking inspiration from the state of art.

Most important aim of the invention is to increase the refrigeration efficiency by comprising MPE (Multi Port Extruded) aluminum pipe. In other words, it increases the refrigeration efficiency by using micro-channel aluminum pipe. Characteristic of the aluminum pipe is that it is not a round profile, but it is flat and comprised of certain number of channels therein. Thus, flat profile MPE pipe used as condenser discharges the heat by contacting to side metal sheet of the refrigerator. Since more surface areas make contact, the heat transfer will be more efficient compared to the state of art. Further, since aluminum pipe is employed, the heat transfer increase more and more because heat transmission coefficient of the aluminum is higher than steel materials. Thus, less pipe will be used, i.e. less material will be used, and it will be possible to reach to desired condenser capacity.

Structural and characteristic specifications and all advantages of the invention will be understood more clearly by means of following figures and detailed description written by making references to these figures and therefore, assessment should be done by taking into consideration these figures and detailed description.

DETAILED DESCRIPTION OF THE INVENTION

The detailed description relates to static MPE condenser allowing for discharging the heat in the cooling room, that is used for house, store and industrial types of refrigerators and refrigerating systems.

As is known, the refrigerating system is comprised of four main components. Those are compressor, condenser, capillary pipe and evaporator. Evaporator absorbs the heat in interior portion of the refrigerator by means of the refrigerant and transmits it to condenser over compressor. The heat is discharged to environment by means of the condenser. The invention increases the amount of transferred heat by widening the heat transfer surface. Refrigerant increasing to the high pressure by compressor goes into condenser in gas form. Here, refrigerant has a high condensation because of its high pressure. Refrigerant engaging with the lower temperatures in the outer environment starts to condense by discharging heat to outside because of the temperature difference. Here, the heat transfer is carried out towards the air in the outer environment from the side surface (110) of refrigerator. Or the condenser is mounted to rear side of the refrigerator and thus, contacts directly with the air without any metal sheet and discharges the heat outside.

Figure 1 illustrates a prior art static condenser. Here, the condenser (300) in the form of classic type of serpentine allows the heat (100) to spread at side portion of the refrigerator by contacting with metal sheet at the side surface (110) of refrigerators. In the current case, classic types of condensers (300) are formed in the round profile shape. Serpentine makes a linear contact with the side surface (110) of the refrigerator and the heat transfer is ensured in this narrow spot. In this way, since the heat transfer spot is insufficient, it is necessary to use longer lengths of steel pipe. In classic type of condensers (300) in present applications, use of round profile pipes and therefore, insufficiency of the heat transfer surface contacting to side metal sheets of the refrigerator causes such applications to be inefficient.

Figure 2, 3 and 4 illustrates the inventive static MPE condenser. In the present invention, the contact surface (212), wherein the static MPE condenser (200) is engaged on the side surface of the refrigerator (100), is wider compared to the present application by means of use of flat pipe (210) with different profiles. Thus, the amount of heat transferred is increased and it is ensured to achieve the same capacity as condensers (300) used in the present application by means of use of shorter flat pipe (210). Further, that use of aluminum materials in the invention, of which heat transmission coefficient is greater than steel pipes, makes an advantageous contribution to the heat transfer. Due to use of the flat pipe (210) in the construction of static MPE condenser by forming it into serpentine shape in the invention and increase of the contact surface (212), the heat transfer surface also is increased and thus, the heat amount transferred through both transmission and natural convection is increased as well. Thus, it is ensured that classic type of condensers (BOO) used in the present applications performs the same function with less materials despite of reduction in the pipe length. Further, it is ensured that the refrigerant may flow more regularly and swiftly by means of dividing the interior portion of the flat pipe (210) by the micro channels. And this hastens the refrigeration process.

Protection scope of the application is determined in the claims and it is to be understood that it cannot be limited to the above-mentioned description for the purpose of illustration. It is clear that any innovation to be provided by a person skilled in the art by means of change in parts in form and use of similar embodiments can be applied in other areas for similar objects. Therefore, it is obvious that such embodiments will lack criteria of invention.
