Description

A HEAT EXCHANGER
TECHNICAL FIELD
The invention relates to a heat exchanger for heat transfer by a single fluid circulation for heating and/or cooling.
BACKGROUND
Heat exchangers are generally used to transfer heat from one fluid to another in refrigeration, air conditioning, heating, power generation, and chemical processes. In the state of the art, heat exchangers are available in at least two different types, tubular and plate-shaped. In the said heat exchangers, two different fluids, the heater fluid, and the refrigerant must circulate within the heat exchanger body. In order to prevent the said fluids from mixing, there should be sections with different fluid paths inside the heat exchanger body. This increases the production cost of the heat exchanger.
In the state of the art, the said heat exchanger can be deformed over time due to fluids at different temperatures circulated in their bodies. If this deformation is in the sections separating the fluids from each other, the fluids may mix. This prevents effective heat transfer. The circulation of two different fluids from the said heat exchanger body causes solid matter to accumulate in the body over time, and thus obstructions in the body, especially in the inlet and outlet sections. This reduces the efficiency of the heat exchanger and may cause undesirable results in other systems where the heat exchanger is connected.
In the heat exchangers disclosed in the state of the art, to circulate two different fluids in the body, both fluids must be pressurized and driven. For this, systems that can pressurize and drive both fluids should be included in the heat exchanger. This increases the cost of the heat exchanger. Furthermore, more energy is used in the heat exchanger to pressurize and drive the two different fluids. This reduces productivity.
All the problems mentioned above have made it necessary to make an innovation in the relevant technical field as a result. BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a heat exchanger to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field.
The object of the present invention is to develop a heat exchanger to allow the circulation of a single fluid within the body. In this way, the mixing of different fluids within the body is prevented.
The object of the present invention is to develop a heat exchanger to transfer heat by circulating a single fluid within the body.
Another object of the present invention is to develop a heat exchanger to provide heat transfer to the fluid passing through the body through the heat pipe(s).
Another object of the present invention is to develop a heat exchanger to transfer heat by consuming minimum energy. Hence, the efficiency of the heat exchanger increases.
To achieve all the objects mentioned above and that will emerge from the following detailed description, the present invention is a heat exchanger comprising at least one body in which only a first fluid circulates and has at least one inlet section and at least one outlet section, performing heat transfer by a single fluid (first fluid) circulation for heating and/or cooling. Accordingly, its novelty comprises at least one heat pipe at least a part of which is connected to the body in such a way that it is located in the interior of the body. Thanks to the heat pipe, heat is transferred to the first fluid circulating in the body.
A possible embodiment of the invention is characterized in that it comprises at least one second fluid in which the other end of the heat pipe outside the body contacts (or is submerged in). The said second fluid is preferably in at least one chamber.
A possible embodiment of the invention is characterized in that the number of the said heat pipes is more than one to increase the surface area in contact with the first fluid circulated in the body. In this way, heat transfer is accelerated and the heating time of the said first fluid is shortened. Another possible embodiment of the invention is characterized in that it comprises at least one pipe body having two ends closed, at least one wick, and at least one heat pipe comprising at least one third fluid contained in the pipe body. The said third fluid is the fluid with a high evaporation rate in the vacuum environment such as water, ethanol, methanol, and ammonia. In this way, the heat energy given from one end of the heat pipe is transferred to the other end almost instantly very quickly.
Another possible embodiment of the invention is characterized in that it comprises at least one connection section on the body, which enables at least one heat pipe to be connected in such a way that at least a part of the at least one heat pipe remains within the body. The heat exchanger further comprises at least one sealing element for sealing between the heat pipe and the body. In this way, the first fluid is prevented from leaking from the area where the heat pipe is connected to the body or from the connection section.

The said heat exchanger (D) further comprises at least one heat pipe (2) at least a portion of which is connected with the body (1 ) in such a way that it is located in the interior of the body (1 ).

In an exemplary embodiment of the invention, the end of the said heat pipe (2) other than the body (1 ) is contacted/immersed in the second fluid. With the heat of the said second fluid, the third fluid in the heat pipe (2) passes into the vapor phase and transfers the heat very quickly (in other words, instantly) to the other part of the heat pipe (2) in the body (1 ). The heat transferred to the portion of the heat pipe (2) in the body (1 ) is transferred to the first fluid circulated in the body (1 ) in contact with this portion. Heat transfer is provided in this way.
In a preferred embodiment of the invention, the said heat exchanger (D) comprises at least one connection section (3) on the body (1 ), which allows at least one heat pipe (2) to be connected in such a way that at least a part of it remains within the body (1 ).
In a preferred embodiment of the invention, the said heat exchanger (D) comprises at least one sealing element for sealing between the heat pipe (2) and the body (1 ). In this way, the first fluid is prevented from leaking from the region where the heat pipe (2) is connected to the body (1 ) or from the said connection section (3).
In a preferred embodiment of the invention, the said inlet section (1 a) is the element in which the first fluid is introduced into the body (1 ). The said outlet section (1 b) is the element where the first fluid, which is heat transferred in the body (1 ), exits the body (1 ).
The scope of protection of the invention is specified in the attached claims and cannot be limited to those explained for sampling purposes in this detailed description. It is evident that a person skilled in the art may exhibit similar embodiments in light of the above-mentioned facts without drifting apart from the main theme of the invention.
