Background
To ensure a sufficiently large heat exchange area, the heat exchanger elements (e.g. condenser elements) are usually provided with a bent shape, e.g. a U-shape, and an inlet and an outlet are provided in a side plate at one end of the U-shape. Depending on the particular environment of use, the heat exchanger components may be placed vertically (i.e., the U-shape is in a vertical plane with the U-shaped opening upward) or horizontally (i.e., the U-shape is in a horizontal plane).
In particular, in container refrigeration units, the condenser components thereof are typically placed in a vertical position, as shown in fig. 1, subject to space constraints. The structure has the advantage of ensuring that a larger heat exchange area can be realized in a limited unit space. However, in practice, both the inlet and outlet of the condenser element are provided at a higher end position, for example at the upper right end of the condenser element as shown, which results in a more pronounced liquid accumulation problem in the condenser element: when the unit is in a stop state, liquid refrigerant positioned at the middle lower part of the U-shaped condenser part cannot be discharged through the liquid outlet due to gravity and is accumulated at the lower part of the U-shaped condenser. Liquid accumulation in the condenser part causes at least the following two problems: (1) The accumulated liquid can cause sudden pressure increase when the compressor is started, and the service life and the use reliability of the compressor are affected; (2) The accumulated liquid can also cause the initial heat exchange area of the condenser part to be reduced, and the heat exchange performance of the unit is affected.

Detailed Description
In combination with the problem of liquid accumulation of the condenser component of the container refrigeration unit in the prior art, the first aspect of the invention provides a novel heat exchanger component, which not only can ensure that the heat exchange area is not affected (namely, the U-shaped structure of the heat exchanger component is reserved), but also can ensure that liquid accumulation is not easy to occur when the heat exchanger component is used as a condenser and is vertically placed, thereby protecting the compressor in the starting process of the compressor and ensuring that the initial heat exchange area of the heat exchanger is not reduced, and further particularly meeting the use requirement of the container refrigeration unit.
Fig. 2 schematically shows the structure of a heat exchanger element according to a preferred embodiment of the present invention. As shown, the heat exchanger element of the present invention is generally U-shaped in configuration, for example, comprising a bottom section and two side sections, preferably arranged in a generally parallel manner and joined together with a smooth transition between the bottom sections. The structure can keep the shape of the main body of the container to the greatest extent, thereby providing the maximum heat exchange area in a limited space, and being particularly suitable for the container refrigerating unit. Of course, the heat exchanger components of the present invention are not limited to use in a container refrigeration unit, but may be used in any other suitable application.
The main difference with the prior art is that in the heat exchanger element according to the invention a header assembly 4 is provided in the bottom section of the U-shaped structure, and preferably with the opening of the header assembly 4 downwards or obliquely downwards, so that when the heat exchanger element is used as a condenser, the liquid refrigerant therein is automatically discharged under the influence of gravity. It is obvious that the heat exchanger element according to the present invention should further comprise a heat exchanger coil and a gas distribution pipe assembly 3, said gas distribution pipe assembly 3 and said liquid collection pipe assembly 4 being in communication with said heat exchanger coil, respectively, so as to facilitate the entry of high temperature and high pressure gaseous refrigerant into the heat exchanger coil through the gas distribution pipe assembly 3 and the exit of liquid refrigerant after heat release by condensation in the heat exchanger coil through the liquid collection pipe assembly 4, for example into a downstream liquid storage device.
Because the liquid collecting pipe assembly 4 is arranged at the bottom section of the U-shaped structure of the heat exchanger component, when the heat exchanger component is vertically placed, the bottom section of the U-shaped structure is positioned at the lowest position, and liquid refrigerant easily flows out through the liquid collecting pipe assembly 4 under the action of gravity, so that liquid accumulation is prevented.
On the other hand, even if the heat exchanger element of the present invention is placed horizontally, i.e. the U-shaped structure is placed in a horizontal plane, the bottom section is at the same height as the two side sections, and the liquid refrigerant in the heat exchanger coil can flow out through the header assembly 4 under the action of gravity as well, which is substantially the same as the effect of the prior art in which the liquid outlet is provided at one end of the side sections.
In the above solution, the heat exchanger coils on both sides of the header assembly 4 may be independent from each other or may be consecutive to each other, as long as communication with the header assembly 4 is ensured.
In the above-mentioned scheme, the position of the gas-distributing pipe assembly 3 can be set at will, for example, can set up at two free ends of U-shaped structure, also can set up any position department between two free ends, as long as guarantee that the gas that the compressor discharged can get into the heat exchanger coil smoothly. Preferably, however, the gas distribution tube assembly 3 is likewise arranged in the bottom section of the U-shaped structure and preferably beside, above or below the liquid collection tube assembly 4, so that the overall shape of the heat exchanger components is simplified and the arrangement of the tubes is facilitated.
As a preferred structure, as shown in fig. 2, the heat exchanger component of the present invention may include a first heat exchanger assembly 1 and a second heat exchanger assembly 2, at least one of the first heat exchanger assembly 1 and the second heat exchanger assembly 2 has an L-shaped structure, the first heat exchanger assembly 1 and the second heat exchanger assembly 2 are spliced to form the U-shaped structure, and the gas distribution pipe assembly 3 and the liquid collection pipe assembly 4 are disposed at a splicing position.
That is, the heat exchanger element of the present invention may comprise two relatively independent heat exchanger assemblies which are joined to form the aforementioned U-shaped structure and which ensure that the gas distribution pipe assembly 3 and the liquid collecting pipe assembly 4 are positioned at the bottom section of the U-shaped structure, wherein the coils of the two heat exchanger assemblies may communicate at the joining location or with the gas distribution pipe assembly 3 and the liquid collecting pipe assembly 4, respectively, at the joining location.
The first heat exchanger assembly 1 and the second heat exchanger assembly 2 may be both L-shaped structures, or may be only one of the L-shaped structures, and the other may be, for example, an I-shaped structure, so long as they can be spliced to form a substantially U-shaped structure.
It is easily conceivable that the first heat exchanger assembly 1 and the second heat exchanger assembly 2 each comprise two side plates, and that in the splicing position one side plate of the first heat exchanger assembly 1 and one side plate of the second heat exchanger assembly 2 are arranged opposite each other, and that the gas distribution pipe assembly 3 and the liquid collecting pipe assembly 4 are arranged between the two side plates arranged opposite each other.
Of course, the heat exchanger element of the present invention may also comprise more than three heat exchanger assemblies, which are spliced together to form the U-shaped structure, as long as a splice position at the bottom section is ensured for facilitating the arrangement of the gas distribution pipe assembly 3 and the liquid collection pipe assembly 4.
It is particularly preferred that the first heat exchanger assembly 1 and the second heat exchanger assembly 2 are symmetrical L-shaped structures, i.e. the bottom sections of the two L-shaped structures are of equal length and the side sections are of equal length. The structure can simplify the manufacturing process of the heat exchanger component and reduce the cost. In addition, when such a structure is employed, the gas distribution pipe assembly 3 and the liquid collecting pipe assembly 4 are located at the intermediate position of the bottom section of the U-shaped structure, and it is also convenient to arrange pipes and other components such as a liquid storage device and the like.
Preferably, the gas distribution pipe assembly 3 is respectively communicated with the coil pipe of the first heat exchanger assembly 1 and the coil pipe of the second heat exchanger assembly 2, and the liquid collecting pipe assembly 4 is respectively communicated with the coil pipe of the first heat exchanger assembly 1 and the coil pipe of the second heat exchanger assembly 2.
For example, as shown in fig. 3 to 4, the gas distribution pipe assembly 3 may include a plurality of gas distribution branch pipes 32, and the gas distribution branch pipes 32 respectively communicate the coil pipes of the first heat exchanger assembly 1 and the coil pipes of the second heat exchanger assembly 2 on the left and right sides; preferably, the gas distribution pipe assembly 3 may further include a first manifold 31, and a plurality of gas distribution branch pipes 32 are commonly connected to the first manifold 31. Likewise, the header assembly 4 may also include a plurality of header branches 42, and these header branches 42 respectively communicate with the coil of the first heat exchanger assembly 1 and the coil of the second heat exchanger assembly 2 on the left and right sides; preferably, the header assembly 4 may further comprise a second manifold 41, and a plurality of header branches 42 are commonly connected to the second manifold 41.
The gas distribution pipe assembly 3 and the liquid collecting pipe assembly 4 are both communicated with the coils of the two heat exchanger assemblies at the same time, namely, the two heat exchanger assemblies are in parallel connection, and the obvious advantage is also achieved that the paths of the gaseous refrigerant reaching the liquid collecting pipe assembly 4 after entering the coils of the two heat exchanger assemblies can keep good consistency, so that the heat exchange efficiency of the two heat exchanger assemblies is basically consistent.
Alternatively, the gas-distributing pipe assembly 3 can be directly communicated with only one of the coil pipes of the first heat exchanger assembly 1 and the coil pipes of the second heat exchanger assembly 2, and the coil pipes of the first heat exchanger assembly 1 and the coil pipes of the second heat exchanger assembly 2 are communicated through another gas-distributing pipe; likewise, the header assembly 4 may be in direct communication with only one of the coils of the first heat exchanger assembly 1 and the coils of the second heat exchanger assembly 2, while the coils of the first heat exchanger assembly 1 and the coils of the second heat exchanger assembly 2 remain in communication through additional liquid passing tubes. This structure also achieves the object of the invention.
Preferably, the first heat exchanger assembly 1 and the second heat exchanger assembly 2 are connected together by welding, thereby forming a stable U-shaped structure. And when the first heat exchanger component 1 and the second heat exchanger component 2 are welded, the gas distribution pipe component 3 and the liquid collecting pipe component 4 are also respectively welded with the corresponding gas inlet pipe and the corresponding liquid outlet pipe, so that the connection strength and the tightness are ensured.
Alternatively, the first heat exchanger assembly 1 and the second heat exchanger assembly 2 may be connected together by screwing or riveting or the like.
Preferably, a reinforcing connection structure is provided at the splice location of the first heat exchanger assembly 1 and the second heat exchanger assembly 2 to improve the strength at the splice location and prevent loosening during transportation.
Preferably, as shown in fig. 3 and 4, the reinforcing connection structure includes an upper connection plate 5 and a lower connection plate 6, which are respectively disposed above and below the splice location, and are fixed, for example, by means of threaded fasteners or welding, to secure the strength at the splice location.
Preferably, as shown in fig. 3 and 4, said upper connection plate 5 may comprise a zigzag frame structure, which is for example directly connected at the upper edges of the oppositely arranged side plates of the two heat exchanger assemblies. The middle of the upper connecting plate 5 is hollowed into a shape like a Chinese character 'hui', so that a space can be reserved for welding operation, and a welding gun can be operated when two heat exchanger assemblies are welded. The lower connection plate 6 may then comprise a plurality of parallel arranged bar members connected at spaced apart relation to each other at the lower edges of the oppositely arranged side plates of the two heat exchanger assemblies. Likewise, the parallel arrangement of the strip members may also be allowed to flow out of the welding operation space to facilitate operation of the welding gun. The nozzles of the gas distribution tube assembly 3 and the liquid collection tube assembly 4 may, for example, be led out from the sides of or between the strip-shaped members of the lower connecting plate 6.
Preferably, the heat exchanger coil may comprise a plurality of rows of U-tubes, and the header assembly 4 may be connected to the heat exchanger coil at the level of the lowest row of U-tubes, which ensures that liquid accumulation is still effectively prevented in the case of a plurality of rows of U-tubes.
In addition, as shown in fig. 3 to 4, the gas distribution pipe assembly 3 and the liquid collection pipe assembly 4 are arranged in the same vertical plane, the gas distribution pipe assembly 3 is arranged on the upper side, and the liquid collection pipe assembly 4 is arranged on the lower side, so that the gap between the first heat exchanger assembly 1 and the second heat exchanger assembly 2 can be minimized, and the maximum heat exchange area can be ensured.
Due to the limited thickness of the heat exchanger components, when the gas distribution pipe assembly 3 and the liquid collection pipe assembly 4 are arranged up and down, the liquid collection pipe assembly 4 may be biased downward so as not to exceed the upper surface of the bottom section of the U-shaped structure, so that its second manifold 41 is lower than the lower surface of the bottom section of the U-shaped structure, as shown in fig. 3. In this case, each bar-shaped member of the lower connection plate 6 is provided in a U-shape so as to accommodate the second manifold 41 between the upper connection plate 5 and the lower connection plate 6.
While the heat exchanger element of the present invention can provide unique advantages when used as a condenser, it will be apparent to those skilled in the art that the heat exchanger element of the present invention can also be used as an evaporator.
On the basis of the above work, a second aspect of the invention provides a container refrigeration unit comprising the heat exchanger component described above, wherein the heat exchanger component acts as a condenser and is arranged with its U-shaped structure opening upwards.
When the container refrigeration unit is in a shutdown state, the liquid refrigerant in the heat exchanger component of the present invention does not stay in the lower portion of the heat exchanger component to form liquid accumulation, but flows out through the liquid collection tube assembly under the action of gravity, for example, is stored in a downstream liquid storage device. For example, in the refrigeration unit, after the compressor is exhausted, the high-temperature and high-pressure gaseous refrigerant enters the heat exchanger component through the gas distribution pipe component, is condensed by the heat exchanger, enters the liquid collection pipe component under the action of gravity, and then falls into a liquid storage device (which is communicated with the liquid collection pipe component) below (also downstream).
Meanwhile, the structure of the heat exchanger component can ensure that the container refrigerating unit is in a limited space, so that the heat exchanger component reaches the maximum heat exchange area.
It should be noted that, in the present invention, terms such as "upper" and "lower" are used, and when these terms are specific to structural features of the heat exchanger component, they are described in the case where the U-shaped structure is placed vertically.
It is easy to understand by those skilled in the art that the above preferred embodiments can be freely combined and overlapped without conflict.
It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
