DETAILED DESCRIPTION OF THE INVENTION

[0027] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that orientation terms such as upper, lower, left, right, front, rear, inner side, outer side, top and bottom mentioned or possibly mentioned in this specification are defined relative to the configurations illustrated in the respective drawings. They are relative concepts, so they may change accordingly according to their different locations and different states of use. Therefore, these and other orientation terms shall not be construed as restrictive terms.

[0028] As shown in FIG. 3, it schematically illustrates the structure of an embodiment of the water chamber structure for a condenser according to the present invention in general. As can be clearly seen from FIG. 3, a water chamber structure 100 for a condenser is composed of an orifice plate 110, a water cover 120, a partition plate assembly 130 and other components. Wherein, the orifice plate 110 is arranged on one end of the condenser, and the water cover 120 is fixed to the orifice plate 110 in a sealed manner to form a water storage space. The main function of the partition plate assembly 130 is to divide the water storage space into a water inlet chamber 140 and a water outlet chamber 150 in a sealed manner. Specifically, the partition plate assembly 130 comprises a first partition plate 131 and a second partition plate 132. Wherein, the top and side walls of the first partition plate 131 are fixed to the inner walls of the water cover 120, and the second partition plate 132 is located below the first partition plate 131. Wherein, the bottom of the second partition plate 132 is fixed to the orifice plate 110, and the side walls of the second partition plate 132 are connected with the inner walls of the water cover 120 in a sealed manner. For example, the side walls of the second partition plate 132 can be closely fitted with the inner walls of the water cover 120 or be closely connected with the inner walls of the water cover 120 by means of rubber pads (not shown). The top of the second partition plate 132 is fixedly connected with the bottom of the first partition plate 131 by bolts, for example. In the partition plate assembly 130, the number and positions of the bolts can be designed according to actual requirements, as long as the tightness of the connection between the first partition plate 131 and the second partition plate 132 is ensured.

[0029] It can be appreciated that, the water chamber structure in the aforementioned embodiment can improve the integrity of the water chamber structure while ensuring the tightness. Compared with the prior art, such a water chamber structure can use a water cover and/or an orifice plate with a thinner wall thickness, thereby helping to reduce the weight of the water chamber structure and thus the overall weight of the condenser. On the other hand, such a water chamber structure can make the water flow evenly distributed, so that the heat exchange performance is greatly improved.

[0030] In a preferred embodiment of the present invention, the first partition plate 131 is provided with a convex portion 133 protruding toward the water inlet chamber 140, that is, the first partition plate 131 has a concave portion in the water outlet chamber 150 to achieve a relatively high structural rigidity. It should be pointed out that the cross-sectional shape of the convex portion 133 can be designed into a regular shape, such as arc, circle, ellipse or square, or can be designed into an irregular shape, such as a special shape. Use of the aforementioned convex portion can effectively change the flow direction of the water flow, so that the water flow entering the water storage space is more evenly distributed, thereby reducing the pressure loss. As an alternative embodiment, the convex portion of the first partition plate 131 may also be configured to protrude toward the water outlet chamber 150, that is, the first partition plate 131 has a concave portion in the water inlet chamber 140.

[0031] Those skilled in the art can appreciate that, the first partition plate 131 and the second partition plate 132 can be arranged to be parallel with each other (refer to FIG. 3), so as to facilitate the operator to assemble.

[0032] In addition, in order to ensure the tightness of the water inlet chamber 140 and the water outlet chamber 150, the top and side walls of the first partition plate 131 can be fixed to the inner walls of the water cover 120 by welding. Furthermore, the bottom of the second partition plate 132 can be fixed to the orifice plate 110 by welding. It should be noted that the partition plate assembly 130 is assembled in the water chamber structure 100 by welding, so that the integrity of the water chamber structure 100 is enhanced, and thus the deformation of the water chamber structure 100 is further restrained.

[0033] As an example, the water cover 120 is provided with a water inlet 121 on one side of the water inlet chamber 140, and is provided with a water outlet 122 on one side of the water outlet chamber 150, as shown in FIG. 3.

[0034] To sum up, compared with the prior art, the water chamber structure for a condenser according to the present invention can achieve better tightness under0 the same pressure difference. In addition, since the integrity of the partition plate assembly is enhanced, the water chamber structure is more strongly constrained, so that thinner water cover and/or orifice plate can be used, thereby reducing the overall weight of the water chamber structure.

[0035] In addition, the present invention provides a condenser provided with the aforementioned water chamber structure for a condenser. Since the water chamber structure is arranged inside the condenser, the water flow inside the condenser is more uniform. Verified by the engineering simulation software CFD (Computational Fluid Dynamics), the water chamber structure can reduce the overall pressure drop and improve the uniformity of the flow velocity between the heat exchange pipes, thus achieving better heat exchange performance.

[0036] In addition, the present invention also provides a refrigeration system equipped with the aforementioned condenser. The refrigeration system comprises a cooling tower, a water chiller, a pumping device and the like that are connected by pipelines, wherein, the water chiller is composed of components such as compressor, condenser, throttling device and evaporator. As mentioned above, the condenser provided with the aforementioned water chamber structure helps to improve the heat exchange performance, so it is highly recommended to apply the aforementioned condenser to various refrigeration systems.

[0037] Some specific embodiments are listed above to illustrate in detail a water chamber structure for a condenser, a condenser provided with the water chamber structure for a condenser and a refrigeration system equipped with the condenser according to the present invention. These individual examples are only used to illustrate the principle of the present invention and the implementations thereof, but not to limit the present invention. Those skilled in the art may, without departing from the spirit and scope of the present invention, make various modifications and improvements. For example, for the purpose of manufacturing convenience, the first partition plate 131 and the second partition plate 132 can use the same material, for example, the first partition plate 131 and the second partition plate 132 can both be made of high-strength steel or other materials. Therefore, all equivalent technical solutions shall belong to the scope of the present invention and be defined by the respective claims of the present invention.
