The temperature control kettle module of this patent has four schemes in total, as follows:

The first option:

As shown in Figure 1, it includes a hot water tank 1, a cooling water tank 2, a heat exchange device, a pumping mechanism and a temperature control mechanism;

Wherein the heat exchange device is provided with a water outlet 3, a first flow channel 4 and a second flow channel 5, and a heat exchange part is arranged between the first flow channel 4 and the second flow channel 5, and the heat exchange part connects the first flow channel 4 The first flow channel 4 is connected to the water outlet 3 and the hot water tank 1 respectively, the second flow channel 5 is connected to the cooling water tank 2, and the cooling water tank 2 is connected to the cooling water tank 2. A first waterway pipe 8 and a second waterway pipe 9 are respectively arranged between the second flowways 5, the first waterway pipe 8 is connected to the water inlet end of the second flowway 5, and the second waterway pipe 9 is connected to The water outlet 3 of the second flow channel 5 and the water inlet of the cooling water tank 2, and the water inlet and the water outlet 3 of the cooling water tank 2 are respectively arranged on the top and bottom of the cooling water tank 2, and the first pump The body 6 is arranged in the first waterway pipeline 8, and the above-mentioned structures are connected to form a temperature-controlled waterway;

Wherein the pumping mechanism is used to control the water flow rate and the water flow direction of the temperature-controlled waterway, specifically, the pumping mechanism includes a first pump for controlling the water flow rate and the water flow direction of the waterway between the cooling water tank 2 and the second flow channel 5 body 6, and a second pump body 7 for controlling the water flow rate and direction of water flow in the waterway between the hot water tank 1 and the first flow channel 4; wherein, the first pump body 6 and the second pump body 7 are two-way water pump structures . With the structure of two-way water pump, the first pump body 6 and the second pump body 7 can pump the residual water in the heat exchange device back to the hot water tank 1 and cooling water tank 2, preventing the residual water from affecting the temperature detection of the temperature control mechanism , but also can improve water utilization.

The temperature control mechanism is used to monitor the water flow temperature of the temperature control waterway. Specifically, the temperature control mechanism may be an NTC temperature sensor distributed in the temperature control waterway.

In this solution, the hot water tank 1 can be any element capable of providing hot water such as a kettle, a hot tank, and a heat pipe. The cooling water tank 2 is a container or element capable of water cooling.

In this solution, the water inlet and outlet 3 of the cooling water tank 2 are respectively arranged on the top and bottom of the cooling water tank 2. Since the density of the hot water is smaller than that of the cold water, the cooling water passes through the second channel 5. It is heated and returns to the top of the cooling water tank 2. At this time, the top water temperature of the cooling water tank 2 is high and the bottom water temperature is low, which will form stratification, which can avoid the mixing of water temperatures and affect the follow-up work effect.

By adopting the above structure, the water with high water temperature at the top of the cooling water tank 2 can be extracted and cooled by the water cooling fan 10, and at the same time, the stratification of the water inside the cooling water tank 2 can be ensured, and the mixing of water temperatures can be avoided to affect the follow-up work effect.

The fourth option:

As shown in Figure 4, based on the improvement of the first solution, a third water pipe 11 is provided between the first flow channel 4 and the water outlet 3, and an instant heat module 12 for heating is provided on the third water pipe 11 . Through the provided instant heating module 12, heat can be supplemented to the water at the water outlet 3, and the temperature of the outlet water can be further accurately controlled.
