Description

Casing structure of vertical centrifugal heat pump {CASING ASSEMBLY FOR UPRIGHT CENTRIFUGAL HEAT PUMP}

The present invention relates to a casing structure of a vertical centrifugal heat pump, and more specifically, it is optimized for a vertical heat pump to sufficiently cool down the operating heat, facilitate the connection work of various pipes (wiring), and It relates to a casing structure of a vertical centrifugal heat pump which can protect the device and significantly reduce operating noise.

In general, a boiler is widely used as a supply device for heating or hot water. These boilers heat water for a period of time and supply it to the water supply or heating facility through piping. Here, as a means for heating the water, it is common to provide a separate combustion chamber to heat the water.

In recent years, boilers have improved performance due to the development of technology, while handling is simplified, but the structure is complicated, which requires a high level of technology in the process cost and maintenance. In addition, the burden on the supply and demand of fuel according to the cost and high costs associated with boiler handling is increasing.

In order to solve this problem, various types of energy-saving boilers have been proposed.

However, these energy-saving boilers, like conventional boilers, have to face some limitations in saving energy in a way of heating water by burning fuel such as oil, gas, and coal.

In particular, in the reality that the energy resources are exhausted and the total amount of energy is imported from abroad, the necessity of alternative energy means to solve such long-term high oil price burden is increasing.

In addition, security of energy resources, such as enactment of national energy conservation laws, is more important than ever due to the entry into force of the climate convention. Therefore, the development of the heating / hot water supply facilities through the use of non-fossil fuel is urgently required.

There is a centrifugal heat pump that does not use such fossil fuel, that is, to make a low-temperature fluid high temperature by using kinetic energy through axial rotational force without heat generation by combustion products.

The centrifugal heat pump rotates a disk at high speed through a shaft in a housing having a constant enclosed space, so that fluid molecules flowing along the inside of the housing collide with each other, so-called cavitation phenomenon (the flow is accelerated in the fluid and the pressure is low. When it occurs, the gas in the water is separated and bubbles are generated) so that a low temperature fluid is changed into a high temperature fluid.

However, in the conventional centrifugal heat pump, as shown in FIG. 1, the rotating shaft 61 is exposed to the side of the motor 60, and the first body 10 and the second body 20 connected to the rotating shaft 61 have a flange portion ( 11) to achieve a fixed state. Here, a perforated disc (not shown) is mounted on the first body 10 and the second body 20 so that the cold water introduced into the cold water inlet pipe 2 is introduced through the inlet pipe 15 so that Centrifugal heat inside to switch to hot water. The converted hot water is discharged to the hot water outlet pipe 3 through the outlet pipe 16.

Conventional centrifugal heat pump having such a configuration has a disadvantage in that the installation space is largely required because the motor and the flange portion 11 is disposed in the state lying on the side.

In addition, the rotating shaft 61 is connected to the flange portion 11 in an exposed state, which is vulnerable to external shock and may be damaged by external factors. Furthermore, mechanical connections are made via the rotary shaft 61 and the perforated discs inside the flange 11 and couplings (e.g. universal joints) and mechanical seals on these connecting shafts. Such a sealing means is required, and thus the connection part is exposed to the outside, which is vulnerable to external impact and requires a large installation space.

The installation space is consumed by installing the motor and the centrifugal heating part of the conventional centrifugal heat pump lying down, and the connection part of the motor and the centrifugal heating part is connected to the coupling and exposed to the outside, which is vulnerable to external shock and greatly consumes the installation space. In order to solve the problem, the applicant has proposed a centrifugal heat pump of the vertical type through Patent Application No. 2011-0117072.

However, in the conventional vertical heating pump, a dedicated casing (air cooling circulation structure corresponding to the vertical cooling) has not been proposed, which solves problems such as heat generation, operation noise, and external shocks when the heating pump is operated. Could not.

The present invention was devised to solve the above problems, and is optimized for the vertical heating pump to sufficiently reduce the operating heat of the motor, facilitate the connection of various pipes (wiring), and protect the device from external shocks. It is an object of the present invention to provide a casing structure of a vertical centrifugal heat pump capable of reducing operating noise.

According to an embodiment of the present invention for achieving the above object, a casing structure for receiving a vertical centrifugal heat pump that is vertically arranged a drive unit and a heat generating unit, the casing body accommodating the drive unit and the heat generating unit; An inlet formed in an upper portion of the casing main body and formed as a passage through which external air is sucked in various directions, and a suction unit provided therein with a fan for introducing the external air into the casing main body; A door part installed at a side of the casing body and opened in one direction and having a grip for holding on the front surface thereof; And an exhaust part formed under the casing main body and circulating the external air introduced into the casing main body to the outside again. The casing structure of the vertical centrifugal heat pump is provided.

The casing body may further include a plurality of auxiliary door parts which are opened in different directions and may be wired or piped around the casing main body and facilitate maintenance.

The casing body has a flat cross section so as to form a hexagon, and the door portion and the auxiliary door portion may be hinged to the casing body, one side of each of which is formed in the form of each of the two sides of the hexagon.

The fan may be formed inside the suction port.

The drive unit and the heat generating unit may be vertically connected via a plate, and the air introduced through the suction port may hit the plate and be exhausted in a perpendicular direction through the exhaust unit.

According to the present invention, it is possible to efficiently lower the operating heat by introducing a circulation structure that introduces the outside air from the upper suction portion to the inside to cool the driving portion and exhaust the heated air to the outside by using the temperature difference between the inside and the outside. By applying the casing structure optimized for the heat pump, there is an effect that can protect the device from the internal noise and external impact factors.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention before the description, terms referring to components of the present invention have been named in consideration of the functions of the respective components, and therefore, it should be understood that the technical components of the present invention are not to be construed as limiting Will be.

Figure 2 is an exemplary view of the vertical centrifugal heat pump installed in the casing structure of the vertical centrifugal heat pump according to an embodiment of the present invention, a brief look at the structure of the vertical centrifugal heat pump applied to the casing structure of the present invention first Same as

The vertical centrifugal heat pump includes a motor 100, a fixed plate 130, a housing 210, a disk 251, and a drive shaft 250.

The motor 100 is installed so that the rotating shaft 110 is positioned below, the motor 100 is coupled to the fixing plate 130 and the rotating shaft 110 is penetrated through the fixing plate 130. The fixing plate 130 may be composed of a first plate 131 integrally formed on one side of the motor 100 and a second plate 132 screwed to the first plate 131. In addition, the second plate 132 may be equipped with a first bearing 120 to facilitate the rotational movement of the front end of the drive shaft 250 (action to reduce friction).

On the other hand, a plurality of support 230 is installed around the fixing plate 130 serves to support this when the motor 100 is installed in a standing state. In addition, the inside of the housing 210 is provided with a guide plate 240, the guide plate 240 is installed in close proximity to the inflow path 150, the supply water supplied to the inflow path 150 of the uppermost disk 251a Guide to the through hole (H1). In detail, the guide plate 240 is divided into a first plate 241 and a second plate 242 so that the supply water introduced into the housing 210 is not filled in the housing 210. When the shaft is rotated, idling occurs to guide the supply water to the flow path of the uppermost disk 251a to prevent the smooth collision and guidance of the fluid.

 The drive shaft 250 is coaxially connected to the rotation shaft 120 of the motor 100. That is, a spline (or a key groove method) may be formed on the rotation shaft 120, and a spline groove may be formed on the driving shaft 250 to be directly connected on the coaxial line. In addition, since the tip is fixed through the first bearing 120 mounted on the fixing plate 130, power transmission can be easily performed without a separate coupling. Can be miniaturized.

The disk 251 has a structure in which a plurality of disks 251 are installed at predetermined intervals. The disk 251 is formed with the inlet hole (H3) and the induction hole (H2) vertically communicated in the inlet groove (H3). Accordingly, the fluid introduced into the disk 251 forms a flow path discharged into the guide hole H2 through the inflow groove H3. Accordingly, the induced fluid is finely pulverized (impacts with water molecules) in the first inlet groove H3, and is secondly pulverized in the induction hole H2 and collided with the inner surface of the housing 210 to be tertiarily pulverized. .

In this process, water molecules collide with each other to cause a phase change in which a low temperature fluid becomes a high temperature fluid. In this case, a closing plate 220 for sealing is installed at the end of the housing 210, and the finishing plate 220 may be formed through the outlet passage 160 through which the high temperature fluid is discharged. In addition, the inflow path 150 is formed at the front end (fixing plate; 130) inside the housing 210 to receive the supply water, thereby causing a collision of water molecules through the disk 251 inside the housing 210, thereby closing. It has a structure to discharge through the outlet path 160 of the plate 220.

Hereinafter, the casing structure of the vertical centrifugal heat pump of the present invention will be described in detail with reference to FIGS. 3 to 6.

Figure 3 is a perspective view showing an open state of the door portion of the casing structure of the vertical centrifugal heat pump according to an embodiment of the present invention, Figure 4 is a perspective view showing the appearance of the casing structure of the vertical centrifugal heat pump according to an embodiment of the present invention 5 is a cross-sectional view showing the internal structure of the casing structure of the vertical centrifugal heat pump according to an embodiment of the present invention, and FIG. 6 is a planar cross section of the casing structure of the vertical centrifugal heat pump according to an embodiment of the present invention. It is a cross section.

As shown in FIG. 3, the casing structure of the vertical centrifugal heat pump according to the present invention includes an intake part 320 at an upper portion of the casing body 300, and an exhaust portion 335, 336, and 337 at the lower portion of the casing body 300.

Specifically, the front of the casing body 300 has a structure in which the door portion 330 is hinged and open to one side. In addition, the door 330 is preferably provided with a handle 338 so that the user can easily grip, and in some cases lock setting.

On the other hand, inside the casing main body 300, the vertical centrifugal heat pump described above is installed, and the upper driving part 410 is installed perpendicular to the lower heating part (centrifugal heating part) 420. Here, it is also preferable to form the support 450 in preparation for the left and right flow of the vertical centrifugal heat pump as shown in FIG.

In order to efficiently cool the vertical centrifugal heat pump, the suction part 320 is formed at the upper end of the casing main body 300. The suction part 320 has a shape protruding upward and has a structure in which a plurality of suction ports 321 and 322 are formed around the suction part 320.

In addition, as shown in FIG. 5, the fan F may be mounted in the suction part 320 to forcibly suck external air. Accordingly, it is possible to cool the driving unit 410 by the outside air by supplying the outside air with the fan F and blowing the inside of the casing main body 300. Here, the fan F may be formed separately in the suction unit 320 as shown in FIG. 5, or the fan F2 formed in the driving unit 410 without the fan F and conventionally introduces external air. It may be applied as a means to.

Meanwhile, a plurality of exhaust parts 335, 336, and 337 are formed under the casing body 300. Accordingly, the outside air sucked from the outside is introduced into the inside through the suction unit 320 to cool the driving unit 410. The outside air heated in this process has a circulation structure which is led back to the outside through the exhaust parts 335, 336 and 337 due to the temperature difference between the inside and the outside (casing body). In particular, the plate 460 is mounted between the driving unit 410 and the heat generating unit 420 so that the air introduced by the fan F cools the driving unit 410 and collides with the plate 460 at approximately right angles. It has a circulation structure discharged to the base (335, 336, 337). That is, the outside air is introduced into the casing and exhausted through the exhaust parts 335, 336, and 337 without moving to the heat generating part 420, thereby improving circulation efficiency and cooling efficiency.

Through this series of actions can significantly lower the operating heat of the drive unit 410 inside. In addition, a centrifugal heat pump may be installed inside the casing main body 300, and a suction material (not shown) may be attached to the inner wall of the casing main body 300 to attenuate the leakage of operating noise to the outside and to reduce external potential impact. There is an advantage to protect the heat pump from the factor.

Meanwhile, an auxiliary door 310 (FIG. 3) may be formed around the door 330 of the casing main body 300 to open in different directions. Specifically, as shown in FIG. 6, the auxiliary door part 310 includes a second door part 330b and a third door part 330c on both sides of the first door part 330a. In addition, the casing main body 300 may have a flat cross section having a regular hexagon, and the door parts 330a, 330b, and 330c may be hinged based on two sides of the hexagon. In addition, although not shown is not limited to the hexagon, the sound can be transformed into a polygon, of course. In addition, the opening direction of the door parts 330a, 330b, and 330c may be variously changed according to the construction situation.

Thus, the side of the casing main body 300 can be opened, respectively, and it is easy to manage and repair a desired part at the time of maintenance. In addition, there is an advantage that the piping work of each pipe (L1 (supply water pipe, hot water supply pipe, etc.)) is easy, and the work of the wiring L2 for electrically connecting the control panel is also easy.

While the present invention has been shown and described with respect to certain embodiments thereof, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, And various modifications may be made without departing from the gist of the technical idea of the invention.
