[0016] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figures 1 to 3As shown, the present embodiment provides an adjustable integrated heat exchanger, including a heat exchanger body 1, wherein the heat exchanger body includes a plurality of water pipes 11 and a plurality of refrigerant pipes 12, wherein the water pipe 11 is located in the refrigerant pipe 12, and a gap for the flow of refrigerant is left between the water pipe 11 and the refrigerant pipe 12, and the refrigerant flows between the water pipe 11 and the refrigerant pipe 12 to perform heat exchange on the water in the water pipe, and a refrigerant central pipe 121 is provided at both ends of the refrigerant pipe 12, wherein the refrigerant central pipe 121 is connected to the plurality of refrigerant pipes 12, and a refrigerant inlet and outlet pipe 122 is provided on the refrigerant central pipe 121, and the refrigerant enters the refrigerant central pipe 121 through the refrigerant inlet and outlet pipe at one end, and then flows through each refrigerant pipe 12, and is concentrated at the refrigerant central pipe 121 at the other end, and is discharged from the refrigerant inlet and outlet pipe 122 at the other end, and the refrigerant at both ends of the water pipe 11 is connected to the refrigerant central pipe 121. The end portion passes through the refrigerant central tube 121, and the refrigerant central tube 121 is used for unified water inlet and outlet. The water pipe 11 extends out of the refrigerant central tube 121, and each water pipe 11 is in contact with and fixed to the refrigerant central tube 121, so that the whole will be stronger, and resonance and vibration caused by friction between the pipes can be avoided. Water central tubes 111 are provided at both ends of the water pipe 11. The water central tube 111 is used to store water and then divert it to each water pipe 11. Several water pipes 11 are connected to the water central tube 111. A water inlet and outlet pipe 112 is provided on the water central tube 111, and a regulating valve 13 for adjusting the size of the refrigerant is provided on the refrigerant inlet and outlet pipe 122. The refrigerant enters the refrigerant uniformly through the refrigerant inlet and outlet pipe 122 through the refrigerant central tube 121, and the flow rate of the refrigerant is controlled by the regulating valve 13 according to different application scenarios.

[0018] When using ordinary heat exchangers, the inlet and outlet flow rates of the refrigerant are set in advance, and then installed on the machine for use. With such a setting, when the use environment changes, the refrigerant size cannot be adjusted, and it cannot adapt to different scenarios. At the same time, when the heat exchanger is used at high power, multiple heat exchangers will be bundled together, and each heat exchanger has an independent hot water inlet and outlet, an independent refrigerant inlet and refrigerant outlet. Due to the independent design, each also requires an independent booster pump. Such a design is complex to install, costly, and unstable, so a refrigerant central pipe 121 is required for centralization, and then the refrigerant enters through the refrigerant inlet and outlet pipes 122, and a regulating valve 13 that can adjust the refrigerant size is set on the refrigerant inlet and outlet pipes 122.

[0019] Preferably, the water pipe 11 and the refrigerant pipe 12 are straight structures, and a plurality of the refrigerant pipes 12 are arranged in parallel.

[0020] Preferably, the water pipe 11 is a threaded structure, which can increase the heat exchange area of ​​the inner pipe, thereby improving the heat exchange effect. The straight pipe structure can make the water flow faster and improve the heat exchange rate.

[0021] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are included in the protection scope of the present invention.
