The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

In the description of the present invention, several means one or more.

In the description of the present invention, unless otherwise explicitly limited, terms such as set, formed, and the like should be broadly construed, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the detailed contents of the technical solutions.

Referring to fig. 2 to 4, the present invention discloses an integrated evaporator including a heat exchange tube 100 and a mesh-shaped heat exchange body 200.

The heat exchange tube 100 has a refrigerant input port 120 and a refrigerant output port 130, the mesh-shaped heat exchange body 200 is a three-dimensional mesh structure and at least wraps a part of the heat exchange tube 100, the refrigerant input port and the refrigerant output port are located outside the mesh-shaped heat exchange body 200, and the mesh-shaped heat exchange body 200 is formed on the heat exchange tube 100 and forms an integrated structure with the heat exchange tube 100.

It can be understood that, in the heat exchange process of the evaporator, the refrigerant may enter the heat exchange tube 100 through the refrigerant input port 120 and be output from the refrigerant output port 130, and in the circulation process of the refrigerant in the heat exchange tube 100, the cold or heat of the refrigerant may sequentially pass through the heat exchange tube 100 and the mesh heat exchanger 200 to exchange heat with the outside, thereby implementing refrigeration or heating. The net-shaped heat exchange body 200 is integrally of a three-dimensional net structure and at least wraps part of the heat exchange tubes 100, so that the heat exchange area of the heat exchange tubes 100 can be obviously increased, the heat exchange efficiency of the evaporator can be improved, and the power consumption can be reduced. In addition, since the mesh-shaped heat exchange body 200 is formed on the heat exchange tube 100 and has an integrated structure with the heat exchange tube 100, the heat exchange efficiency of the evaporator can be further improved, and the power consumption can be reduced.

It should be noted that in some heat exchange devices, the functions of the condenser and the evaporator can be interchanged according to different cooling or heating requirements, and therefore, those skilled in the art can easily understand that the evaporator mentioned in the present invention is also referred to as a condenser.

The evaporator and the condenser in the utility model not only refer to the evaporator and the condenser in the traditional sense commonly seen in production and life, but also include the variants of the evaporator and the condenser in the forms of a radiating water tank of a similar automobile engine and the like; the refrigerant in the present invention is not limited to a refrigerant commonly used for Freon and the like, and includes water.

Specifically, current heat exchange tube 100 is split type structure with heat exchanger fin 300, needs the manual work to install and weld both, and the cost of labor is higher, and manual welding hardly guarantees size and leakproofness, more can't satisfy the variety of heat exchanger fin 300 appearance, and the current condenser or the evaporimeter of different appearances need different machinery flow water automatic production line to produce, and manufacturing cost is higher. The net-shaped heat exchange body 200 is formed on the heat exchange tube 100 and is in an integrated structure with the heat exchange tube 100, welding of the net-shaped heat exchange body and the heat exchange tube 100 is not needed, product quality can be improved, the appearance profile of the net-shaped heat exchange body 200 manufactured through a forming process is easy to control, and requirements of condensers or evaporators with different specifications or shapes can be met.

It should be noted that, referring to fig. 2 and 3, the three-dimensional mesh structure is a more three-dimensional shape compared to the sheet structure of the conventional heat exchanger 300, the three-dimensional mesh heat exchanger 200 can wrap the heat exchange tube 100 in a three-dimensional space, when the heat exchange tube 100 is in a curved shape, the mesh heat exchanger 200 can also be filled between each section of curved pipe on the heat exchange tube 100, and the shape of the mesh heat exchanger 200 can be controlled by changing the shape of the mold, and can also be adjusted by a trimming process after molding.

The heat exchange tube 100 of the existing evaporator or condenser is made of copper, the heat exchange fins 300 are made of aluminum, the copper heat exchange tube 100 and the aluminum heat exchange fins 300 are made of different materials, and the copper heat exchange tube 100 and the aluminum heat exchange fins 300 need to be made into a split structure and connected, which can reduce the heat exchange efficiency of the evaporator or condenser. In subsequent use, the surface of the aluminum is easily oxidized, and the heat exchange efficiency of the evaporator or the condenser is also affected. In addition, the copper heat exchange tube 100 is connected to the aluminum heat exchange fins 300 to generate an electrical corrosion effect, thereby accelerating the oxidation of the aluminum material. In some embodiments of the present invention, both the mesh-shaped heat exchanger 200 and the heat exchange tube 100 can be made of copper, which has a higher thermal conductivity and a better oxidation resistance than aluminum, so as to prolong the service life of the mesh-shaped heat exchanger 200. The copper mesh heat exchanger 200 can be better attached to or wrapped around the copper heat exchanger tube 100, so that the evaporator or condenser has a more stable structure and does not suffer from electrical corrosion.

In some embodiments of the present invention, the mesh-type heat exchanger 200 has a capillary structure, and specifically, the mesh-type heat exchanger 200 may be composed of a plurality of substantially tubular capillary tubes, i.e., hollow and thin tubular bodies. The capillary structure is more favorable for improving the heat exchange area of the reticular heat exchange body 200 and the heat exchange efficiency.

In some embodiments of the present invention, the mesh-shaped heat exchanger 200 is formed on the heat exchange tube 100 by electroplating or chemical plating, so that there is no gap at the connection position between the mesh-shaped heat exchanger 200 and the heat exchange tube 100, thereby improving the heat exchange efficiency.

Referring to fig. 4, in some embodiments of the present invention, the heat exchange tube 100 includes a heat exchange tube body 110, a refrigerant input port 120 and a refrigerant output port 130 are respectively disposed at two ends of the heat exchange tube 100, and the heat exchange tube body 110 is integrally formed. The heat exchange tube 100 of the existing evaporator or condenser is formed by sections, and the joints of the sections are welded with elbows, so that the process is complex, and the welding effect and the sealing property are difficult to ensure. The heat exchange tube body 110 of the present invention is integrally formed, so that the process of segmented welding can be omitted, and the quality of the heat exchange tube 100 can be improved.

In some embodiments of the present invention, the refrigerant input port 120 and the refrigerant output port 130 are located at the same side of the mesh-shaped heat exchanger 200, which facilitates the molding process of the mesh-shaped heat exchanger 200 by placing the heat exchange tube 100 in a mold, simplifies the mold structure, and improves the processing efficiency of the mesh-shaped heat exchanger 200.

The specific manufacturing method of the integrated evaporator is as follows:

s1, preparing a heat exchange tube 100;

s2, placing the heat exchange tube 100 in a mould, adding a foaming material into the mould, and foaming the foaming material to form a foaming body with a three-dimensional net structure;

s3, taking the heat exchange tube 100 and the foaming body out of the die together, and carrying out chemical plating to enable the surface of the foaming body to be plated with a metal layer, wherein the metal layer forms a net-shaped heat exchange body 200 with a three-dimensional net-shaped structure, and the net-shaped heat exchange body 200 and the heat exchange tube 100 are of an integrated structure and form a semi-finished product together with the foaming body;

and S4, placing the semi-finished product in a heating container for heating, taking out the heated semi-finished product, and cleaning to remove the foaming body in the net-shaped heat exchange body 200, so that the net-shaped heat exchange body 200 is in a capillary structure.

Step S1 may further include the following steps: a pipe body having a desired length is prepared, and the pipe body is bent into a heat exchange pipe 100 having a desired shape by integral molding, and a refrigerant input port 120 and a refrigerant output port 130 are respectively sleeved at both ends of the heat exchange pipe 100. This can prevent the interference of the molded mesh heat exchanger 200 when the refrigerant inlet port 120 and the refrigerant outlet port 130 are installed. The sleeving of the refrigerant input port 120 and the refrigerant output port 130 specifically includes the processes of nut sleeving, tapping, hole expanding and the like.

If the mesh-shaped heat exchanger 200 is made of copper, the metal layer in step S3 is a copper layer, and the process of plating the copper layer on the foam is a copper deposition process, which can be completed by an automatic copper deposition line. It is understood that the present invention can also be made into the mesh heat exchanger 200 by nickel plating.

The foaming material in step S2 may be polyurethane, which is one of the commonly used foaming materials, and the polyurethane can be foamed into polyurethane wool with a three-dimensional net structure under a certain foaming process, i.e. the foaming body mentioned in the above step, which is a foaming process well known to those skilled in the art. The foamed body can be cleaned off by means of a corresponding cleaning agent, for example a polyurethane cleaning agent. It will be appreciated that other foamed materials may be used to achieve the objectives of the present invention.

The specific manufacturing method of the heat exchange structure can further comprise at least one of the following steps:

s5, electroplating the cleaned heat exchange tube 100 and the net-shaped heat exchange body 200 to thicken the whole wall; s6, silver precipitation treatment is carried out on the cleaned heat exchange tube and the mesh heat exchange body, and washing and drying are carried out; s7, the mesh heat exchanger 200 is perforated.

The silver deposition treatment can perform the disinfection and sterilization effects on the heat exchange tube 100 and the mesh heat exchange body 200, so that the evaporator and the condenser can not generate peculiar smell in the state of working for a long time or not working for a long time, and the silver deposition treatment can also perform the heat exchange and corrosion prevention effects.

Regarding step S7, in some usage environments, if the mesh structure of the mesh-shaped heat exchanger 200 is too dense, the wind power may be too weak, and the heat exchange efficiency of the condenser or the evaporator may be reduced. It is understood that the steps S6 and S7 can be processed according to the actual use environment, and are not essential process elements.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
