[0159] Embodiment 9:

[0160] This embodiment provides a tempering residual heat exchange system with the above-mentioned heat exchange device, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0161] include:

[0162] Heat exchange device;

[0163] Tempering water cooling tank 100;

[0164] A cleaning tank assembly 101, wherein a temperature sensor and an electric heating device are arranged in the cleaning tank assembly 101;

[0165] A first circulation pipe 102, the first circulation pipe 102 connects the tempering water cooling tank 100 and the heat exchange device to form a first circulation water circuit;

[0166] A second circulation pipe 103, the second circulation pipe 103 connects the cleaning tank assembly 101 and the heat exchange device to form a second circulation water circuit;

[0167] A first circulation pump, wherein the first circulation pipe 102 is provided with a first circulation pump;

[0168] A second circulation pump: the second circulation pipe 103 is provided with a second circulation pump;

[0169] Filters: Filters are provided on the first circulation pipe 102 and the second circulation pipe 103 .

[0170] In this embodiment, the water in the tempering water cooling tank 100 is cold water. When the metal parts are tempered, the water in the initial tempering water cooling tank 100 will be heated up to form a first fluid medium. The cleaning tank assembly 101 includes a cleaning tank and a receiving tank. The receiving tank and the cleaning tank are connected by a pipeline. The temperature sensor and the electric heating device are arranged in the receiving tank. The receiving tank provides the cleaning tank with heated water for cleaning the metal parts.

[0171] The first circulation pipe 102 connects the inlet and outlet of the tempering water cooling tank 100 and the first medium pipes 6 at both ends of the heat exchange device, so that the heated water in the tempering water cooling tank 100 circulates in the first medium space; one section of the second circulation pipe 103 connects the water outlet of the cleaning tank and the second medium pipe 7 on one side of the heat exchange device, and the other section of the second circulation pipe 103 connects the water inlet of the heating tank and the second medium pipe 7 on the other side of the heat exchange device, so that the cleaning water in the cleaning tank assembly 101 circulates in the second medium pipe 7; that is, the water in the tempering water cooling tank 100 is a high-temperature medium, and the high-temperature medium circulates in the first medium space to transfer or exchange heat to the low-temperature medium in the second medium space, and the low-temperature medium is the cleaning water that has washed the metal parts and flows out of the cleaning tank. Since the water temperature of the cleaning water will drop after washing the metal parts, a low-temperature medium is formed, which is input into the second medium space through the low-temperature medium, and then heat exchange is performed to form heated cleaning water. After the cleaning water enters the receiving tank, if the cleaning water temperature is not enough, it will be further heated by the point heater to reach the water temperature for washing the metal parts.

[0172] Since the water in the return water cooling water tank and the cleaning tank assembly 101 do not interfere with each other, they will not contaminate each other. At the same time, the water temperature in the return water cooling water tank is used to clean the metal parts in the cleaning tank assembly 101, thereby reducing the heating frequency and output power of the motor thermal device in the cleaning tank assembly 101, better saving energy input in production, and achieving energy saving effects. At the same time, a filter is set to perform preliminary filtering on the medium entering the heat exchange device, thereby reducing the speed of dirt accumulation in the heat exchange device, thereby reducing the frequency of cleaning the heat exchange device.

[0173] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
