Cover side coupling flange surfaces 134 and 144 are also formed at the shell 110 side coupling ends of the covers 130 and 140. At this time, each of the shell-side coupling flange surface 114 and the cover-side coupling flange surface (134, 144) is formed with a bolt fastening hole corresponding to each other to fasten the fastening members 170, such as bolts and nuts.

On the other hand, the size of the above-described upper and lower plates 120, 120a is made of the same size as the circle formed by the shell-side coupling flange surface 114 and the cover-side coupling flange surface (134, 144), the upper and lower plates 120 configured as described above , 120a is positioned between the shell-side coupling flange surface 114 and the cover-side coupling flange surface 134, 144 in each of the upper and lower portions of the shell 110 to be fixed by the fastening member 170 fastened through the bolt fastening hole.

In the configuration of the cylindrical tubular heat exchanger 100 of the present invention configured as described above, the shell 110 is introduced through the shell inlet 112 from the raw water and the hot water to be heat exchanged from the internal combustion engine therein. In order to exchange heat between the fluids of the cold water to be heat-exchanged, such a shell 110 is made of a cylindrical shape with the upper and lower open, but the shell inlet 112, the other cylinder in which the fluid of the cold water to be heat-exchanged to the lower portion of one cylindrical surface flows in The upper surface of the heat exchange is made of a shell outlet 112a through which the fluid in the warmed state flows out and consists of a shell-side coupling flange surface 114 extending at each of the upper and lower ends.

The upper and lower plates 120 and 120a separate the upper and lower space portions 160 and 160a formed by the inside of the shell 110 and the upper and lower shell covers 130 and 140, and then transfer the heat transfer pipes through the upper space portion 160 from the internal combustion engine. To prevent the fluid of the cold water to be heat-exchanged flowing through the shell inlet 112 from the hot water to be heat-exchanged to the lower space 160a and the shell outlet 112a to be directly mixed. For this purpose, the upper and lower plates 120 and 120a are formed in a size formed by the shell side coupling flange surface 114 and are positioned at the upper and lower portions of each of the shell side coupling flange surfaces 114.

The upper and lower plates 120 and 120a are formed such that the plurality of through holes 122 and 122a for connecting the heat transfer pipes 150 to correspond to each other. At this time, the fluid of the hot water to be heat exchanged introduced from the internal combustion engine via the upper space 160 into the through hole 122 of the upper side flows in, and the heat transfer tube 150 into the through hole 122a of the lower side. In the process of flowing the heat exchange is made to flow out of the cold water fluid.

The upper and lower shell covers 130 and 140 are installed at upper and lower sides of the shell 110 to exchange heat in the process of flowing the upper space part 160 and the heat pipe 150 in which the fluid of the hot water to be exchanged from the internal combustion engine is stored. This is to form a lower space portion (160a) for storing the fluid in the cold water state, the fluid inlet tube 132 is introduced into one side of the upper shell cover 130, the fluid in the hot water to be heat-exchanged from the internal combustion engine ) Is provided, and the lower shell cover 140 is provided with a fluid outlet tube 142 through which heat exchange is performed during the flow of the heat transfer tube 150 to allow the fluid of the cold water stored in the lower space 160a to flow out. do.

Meanwhile, cover side coupling flange surfaces 134 and 144 corresponding to shell side coupling flange surfaces 114 are formed at the shell 110 coupling ends of the upper and lower shell covers 130 and 140 as described above. The upper and lower shell covers 130 and 140 configured as described above are fixed to upper and lower portions of the shell 110 by fastening members 170 fastened through a plurality of bolt fastening holes formed on the cover side coupling flange surfaces 134 and 144.

The heat transfer pipe 150 is a cold water state to be heat-exchanged flowing through the shell inlet 112 in the process of flowing the fluid of the hot water to be heat-exchanged and stored in the upper space 160 from the internal combustion engine to the lower space 160a. Heat exchange with the fluid of the heat transfer tube 150, the upper and lower ends of the heat pipe 150, through the through holes 122, 122a formed to correspond to each of the upper and lower plates (120, 120a) through the upper space portion 160 and the lower The space portions 160a communicate with each other.

The heat transfer pipe 150 configured as described above is configured to stand upright inside the shell 110 between the upper and lower plates 120 and 120a so as to be in direct contact with the fluid in the cold water to be heat exchanged introduced through the shell inlet 112. . Therefore, the fluid of the hot water to be heat exchanged flowing inside the heat transfer tube 150 may be said to be heat-exchanged with the fluid of the cold water to be heat exchanged introduced into the shell inlet 112 through the heat transfer tube 150.

The heat dissipation fin 200 is for maximizing the heat exchange efficiency between the fluid in the hot water to be heat exchanged flowing inside the heat transfer tube 150 and the fluid in the cold water to be heat-exchanged introduced into the shell inlet 112, the heat dissipation fin 200 is The through holes 210 through which the heat transfer tubes 150 pass are formed to correspond to the through holes 122 and 122a of the upper and lower plates 120 and 120a, and the shell inlets are formed around the adjacent holes of the through holes 210. The fluid ejection hole 212 ejected upward by the pressure in which the fluid of the cold water to be heat-exchanged introduced into the shell 110 from the inside of the shell 110 is formed. At this time, the size of the heat radiation fin 200 is formed in relation to the inner diameter of the shell (110).

The heat dissipation fin 200 configured as described above is installed at regular intervals up and down so that its edge is in close contact with the inner circumferential surface of the shell 110 between the upper and lower plates 120 and 120a. At this time, a plurality of heat pipe 150 is passed through each through hole 210, the four sides of the through hole 210 adjacent to the heat pipe 150 from the shell inlet 112 to the inside of the shell 110. The fluid ejection hole 212 is ejected upward by the pressure in which the fluid in the cold water to be introduced heat exchange is introduced. At this time, the fluid ejection hole 212 is formed to communicate with the through-hole 210 of the heat radiation fin 200 side through which the heat pipe 150 passes.

On the other hand, the above-described heat dissipation fin 200 is made of a copper plate or a galvalume steel plate so that the heat transfer is better, the shape of the above-described fluid ejection hole 212 may be formed in a rectangular shape as shown in Figs. As shown in FIG. 7, the shape of the fluid jet hole 212a may be in the form of a triangle, and as shown in FIG. 8, the shape of the fluid jet hole 212b may be in the form of a semicircle.

The heat dissipation fin 200 configured as described above has an upper space portion from the internal combustion engine or the like because the heat transfer tube 150 penetrates through the through hole 210 and is in surface contact with the inner circumferential surface of the heat transfer tube 150 and the through hole 210. The heat of the fluid of the hot water to be heat-exchanged flowing into the heat transfer pipe 150 flows into the heat transfer pipe 150 is heat-dissipating fin 200 which is in surface contact with the heat transfer pipe 150 via the heat transfer pipe 150 during the flow of the heat transfer pipe 150. Heats up).

As described above, the heat of the fluid in the hot water to be heat exchanged by the heat radiation fins 200 is eventually transferred to the fluid of the cold water to be heat exchanged introduced into the shell 110 through the shell inlet 112. At this time, the heat transfer is made of the fluid of the cold water to be heat-exchanged introduced into the shell 110 from each heat pipe 150.

Therefore, the cylindrical tube heat exchanger 100 according to the present invention can be seen that the heat exchange is made in a short time compared to the cylindrical tube heat exchanger 10 according to the prior art as shown in Figs. .

Looking at the heat exchange process of the cylindrical tubular heat exchanger 100 according to the present invention configured as described above are as follows. First, in order to cool the internal combustion engine, the fluid in the hot water to be heat-exchanged while the coolant is heated by the internal combustion engine is introduced into the upper space 160 through the fluid inlet pipe 132 of the upper shell cover 130. When the fluid flows through the heat pipe 150 to the lower space 160a, the heat of the fluid of the hot water to be heat exchanged to flow the heat pipe 150 is transferred to the heat pipe 150, and thus, to the heat pipe 150 The heat is transferred to the heat radiation fins 200 which are in surface contact with the heat transfer pipe 150 and the through-hole 210.

On the other hand, as described above, as the fluid in the hot water to be heat-exchanged while being heated by an internal combustion engine or the like flows through the heat-transfer tube 150, the heat of the fluid in the hot water to be heat-exchanged is transferred to the heat-transfer tube 150 and the radiating fin 200. During the process, the cold water fluid (heated fluid to be heat-exchanged with the hot water fluid to be heat-exchanged to obtain hot water for heating or other intended use) through the shell inlet 112 to the inside of the shell 110 When the heat is introduced from the lower portion to the upper portion, the heat transferred by the heat transfer pipe 150 and the heat dissipation fin 200 is a fluid in the cold water to heat exchange inside the shell 110 in direct contact with the heat transfer tube 150 and the heat dissipation fin 200. Electric heat is made.

Therefore, the heat transfer pipe 150 and the heat dissipation fin 200 are rapidly cooled, and thus the fluid in the hot water to be heat exchanged flowing inside the heat transfer pipe 150 is also cooled and cold watered. As a result, the fluid of the hot water to be heat-exchanged flowing through the heat pipe 150 is heat-translated by the fluid of the cold water to be heat-exchanged in which heat is introduced into the shell 110 during the flow of the heat pipe 150. After the water flows into the lower space portion 160a, the water flows out through the fluid outlet pipe 142 and circulates with the coolant such as an internal combustion engine.

On the other hand, the fluid of the cold water to be heat-exchanged introduced into the shell 110 is heated by the heat transfer tube 150 and the heat radiation fins 200 in a process of directly contacting the heat transfer tube 150 and the heat radiation fins 200 to be heated. As such, after the hot water is heated in the process of contacting the heat pipe 150 and the heat dissipation fin 200, the cold water inside the shell 110 gradually leaks into the shell 110 and flows out through the shell outlet 112a to heat or the like. It is used as the desired hot water.

On the other hand, when the fluid in the cold water to be heat-exchanged into the shell 110 through the shell inlet 112 is filled, the fluid inside the shell 110 is formed by the pressure inlet fluid discharge hole formed in the heat radiation fins 200 thereon It is ejected to the upper side through the 212 is filled with the upper heat radiation fin 200 of the upper side. In this case, the fluid ejected through the fluid ejection hole 212 is sprayed on the outer circumferential surface of the upper heat transfer tube 150 and the lower surface of the upper heat dissipation fin 200 to be heated faster by the heat transfer tube 150 and the heat dissipation fin 200. do. When the fluid is filled to the top of the heat dissipation fin 200 on the uppermost side through this process, it is already in the hot water state, and flows out through the shell outlet 112a.

As shown in FIG. 7, the fluid ejection hole 212a has a triangular shape, and FIG. 8 configures the shape of the fluid ejection hole 212b in a semicircular shape. Thus, by forming the shape of the fluid ejection holes (212a, 212b) in a triangle or semi-circle to change the shape of the fluid ejected through the fluid ejection holes (212a, 212b) it is possible to further reduce the time for heat exchange.

9 to 11 are configurations for increasing heat of the heat dissipation fin 200 and the heat dissipation tube 150 to heat the heat transfer tube 150 to the heat dissipation fin 200 more quickly, as shown in FIG. According to another embodiment of the present invention, the heat dissipation fin 200 has a structure in which an electrothermal contact piece 220 is further formed on one surface of the upper and lower surfaces of the heat dissipation fin 200 at an inner circumference of the through hole 210 of the heat dissipation fin 200. .

As described above, in the case where the heat transfer tube 150 is connected to the through-hole 210 through a configuration in which the heat transfer contact piece 220 is formed to protrude, the contact area between the heat transfer tube 150 and the heat dissipation fin 200 becomes larger and the heat transfer tube 150 becomes larger. Heat transfer from the heat sink to the heat sink fin 200 is made faster, that is, the heat transfer efficiency is improved.

Meanwhile, as described above, each of the fluid ejection holes 212c, 212d, and 212e in the heat dissipation fin 200 shown in FIGS. 9 to 11 may be formed through all around the outer circumferential surface of the heat transfer contact piece 220. It is formed so as not to communicate with 210. At this time, the fluid ejection holes (212c, 212d, 212e) may be formed in the shape of a rectangle as shown in Figure 9, may be made in the shape of a triangle as shown in Figure 10, made in the shape of a semi-circle as shown in FIG. It may be.

As described above, according to the present invention, a plurality of heat dissipation fins 200 having a structure in which the fluid ejection holes 212 are formed around the through-holes 210 are installed inside the shell 110 to heat dissipation fins through the heat pipes 150. By allowing the heat of the fluid of the hot water to be heat-exchanged to 200 to be transferred, heat exchange may be performed at a faster time.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the technical idea of the present invention.
