Description

Technical Field

[0001] The present application relates to the field of pipeline machines, and in particular to a VC heat exchanger. Background Art

[0002] Pipeline water coolers are typically used in conjunction with water purification equipment. Currently, they are broadly categorized into wall-mounted hot and cold pipeline water coolers and vertical models. These water coolers can deliver hot, room temperature, cold, or warm water. Currently, the warm water delivered by conventional pipeline water coolers is adjusted to the desired temperature by adjusting the machine's heating temperature.

[0003] Current heat exchangers absorb heat by introducing a heat-absorbing liquid into the heat exchanger and then draining it out. This results in a short contact time between the heating source and the heated fluid, wasting a significant amount of heat and leading to long heating wait times. Summary of the Invention

[0004] In order to shorten the heating waiting time of the pipeline machine, the present application provides a VC heat exchanger.

[0005] The VC heat exchanger provided in this application adopts the following technical solution:

[0006] A VC heat exchanger includes a shell and a heat-equalizing coil;

[0007] A heat exchange chamber is provided inside the shell, and the heat exchange chamber is filled with a heat exchange fluid;

[0008] A heating element is provided inside the heat exchange chamber, and the heating element is used to heat the heat exchange fluid;

[0009] The soaking coil is located in the heat exchange chamber and immersed in the heat exchange fluid. The water inlet and the water outlet of the soaking coil are both located outside the shell.

[0010] Optionally, a water supply pipe and an exhaust pipe are further provided on the shell, and both the water supply pipe and the exhaust pipe are connected to the interior of the heat exchange chamber.

[0011] Optionally, the water outlet end of the water supply pipe extends to the bottom end of the heat exchange chamber.

[0012] Optionally, a water level magnetic float and a water level access switch are installed at the inner top of the heat exchange chamber.

[0013] Optionally, the housing is also equipped with a plurality of temperature-controlled switches with different set temperature values, and the temperature-controlled switches are used to monitor the temperature of the heat exchange fluid in the heat exchange chamber. The temperature-controlled switches are electrically connected to the heating element and can control the opening and closing of the heating element.

[0014] Optionally, the heat equalizing coil includes a water inlet section, a water outlet section, and a coiled section located between the water inlet section and the water outlet section, and the water inlet section, the water outlet section, and the coiled section are internally connected.

[0015] This application includes at least one of the following beneficial technical effects:

[0016] 1. Since the soaking coil is immersed in the heat exchange fluid, when the fluid to be heated flows through the soaking coil, the heat exchange fluid can fully cover the fluid to be heated, so that the fluid to be heated flowing in the soaking coil can more comprehensively exchange heat with the heat exchange fluid, thereby accelerating the heat exchange efficiency between the heat exchange fluid and the fluid to be heated, so that the fluid to be heated in the soaking coil can heat up more quickly, shortening the time required for heat exchange.

[0017] 2. By setting up multiple temperature control switches, when a temperature control switch fails, other temperature control switches can also stop the heating element from continuing to heat, thereby preventing the temperature of the heat exchange fluid from exceeding the set temperature and affecting the temperature of the fluid to be heated.

[0021] The following is combined with Figure 1-2 This application is described in further detail.

[0022] The embodiment of the present application discloses a VC heat exchanger.

[0023] Reference Figure 1 、 Figure 2 The VC heat exchanger includes a housing 1, the interior of which is hollow, forming a heat exchange chamber 11. Heat exchange chamber 11 is filled with a heat exchange fluid, which is non-potable water. A heating element 2 is disposed within housing 1 for heating the heat exchange fluid within chamber 11, thereby increasing the temperature of the heat exchange fluid.

[0024] A water supply pipe 3 and an exhaust pipe 4 are installed on the top of the shell 1, which are connected to the interior of the heat exchange chamber 11. The water supply pipe 3 and the exhaust pipe 4 are both connected to the heat exchange chamber 11 inside the shell 1. The water supply pipe 3 and the exhaust pipe 4 are sealed and fixed to the shell 1. The water outlet end of the water supply pipe 3 extends to the bottom end of the heat exchange chamber 11. When the heat exchange fluid inside the heat exchange chamber 11 is short of water, new heat exchange fluid can be added to the interior of the heat exchange chamber 11 through the water supply pipe 3. Since the heat exchange fluid inside the heat exchange chamber 11 is heated by the action of the heating element 2, the steam generated as the temperature of the heat exchange fluid increases is discharged through the exhaust pipe 4.

[0025] A soaking coil 5 is fixedly installed within the heat exchange chamber 11. Both the water inlet and outlet of the soaking coil 5 extend through the shell 1, extending to the outside of the shell 1. The inner hole of the soaking coil 5 is used to carry the fluid to be heated, which is drinking water. The soaking coil 5 is immersed in the heat exchange fluid within the heat exchange chamber 11. After the drinking water flows through the soaking coil 5, heat is exchanged between the drinking water and the heat exchange fluid within the heat exchange chamber 11, raising the drinking water's temperature to the desired level before it is discharged through the outlet of the soaking coil 5.

[0026] The soaking coil 5 includes an inlet section 501 fixedly connected to the housing 1, a water outlet section 502 fixedly connected to the housing 1, and a coiled section 503 located between the inlet section 501 and the outlet section 502. The inlet section 501, the coiled section 503, and the outlet section 502 are interconnected. The inlet section 501, the coiled section 503, and the outlet section 502 are integrally formed or welded.

[0027] Reference Figure 2 A water level access switch 6 and a water level magnetic float 7 are installed at the top of the heat exchange chamber 11. These are used to monitor the level of the heat exchange fluid within the chamber 11. When heat exchange fluid is added to the chamber 11 through the water supply pipe 3, the float of the water level magnetic float 7 gradually rises as the liquid level within the chamber 11. When it approaches the water level access switch 6, it signals to stop water inflow. As the level of the heat exchange fluid within the chamber 11 decreases, the water level magnetic float 7 descends, signaling a water supply.

[0028] Reference Figure 1 、 Figure 2 Multiple temperature-controlled switches 8 are mounted on the lateral walls of the housing 1 to detect the temperature of the heat exchange fluid within the heat exchange chamber 11. The temperature-controlled switches 8 are electrically connected to the heating element 2 and are used to control the on / off operation of the heating element 2. The two temperature-controlled switches 8 are set to monitor different temperatures. For example, one temperature-controlled switch 8 is set to a desired normal temperature, while the other temperature-controlled switch is set to a temperature higher than the desired normal temperature.

[0029] When the temperature of the heat exchange fluid in the heat exchange chamber 11 reaches the normal required temperature value, the temperature control switch 8 set to the normal required temperature value controls the heating element 2 to turn off, thereby stopping heating the heat exchange fluid. If the temperature of the heat exchange fluid in the heat exchange chamber 11 reaches the normal required temperature value, but the temperature control switch 8 set to the normal required temperature value does not turn off the heating element 2, it can be determined that the temperature control switch 8 set to the normal required temperature value is damaged. When the temperature of the heat exchange fluid continues to rise and reaches the temperature set by another temperature control switch 8, the temperature control switch 8 with the higher temperature setting value controls the heating element 2 to turn off. By providing multiple temperature control switches 8 with different temperature settings, a protective effect can be achieved, preventing the temperature of the heat exchange fluid from continuing to rise, thereby affecting the outlet temperature of the drinking water.

[0030] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
