Description

Technical Field

[0001] This application relates to the field of heat exchange, and in particular to a hybrid heater. Background Technology

[0002] The steam-water mixing heater is a new type of heating device that directly mixes steam and water, using steam to directly heat the water. Compared with other indirect heat exchange equipment, the steam-water mixing heater has the advantages of high heat exchange efficiency, simple installation, and low cost. It is the most ideal steam heating equipment for bath water supply, domestic and industrial hot water supply, and hot water heating systems.

[0003] Existing mixing heaters typically introduce cold water at one end and steam at the other, resulting in a simple mixing process with limited contact between the steam and water. Especially during instantaneous mixing, insufficient turbulence prevents the two from fully diffusing and merging. This manifests as steam condensing into clumps in localized areas or water penetrating the mixing zone, reducing the effective heat transfer area. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and improve the mixing effect of water and steam, thereby providing a mixing heater.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A mixing heater includes a mixing tube, a steam pipe and a water inlet pipe connected to the mixing tube, and a water outlet pipe connected to the other end of the mixing tube; a hollow mixing cylinder is provided inside the mixing tube, the steam pipe is connected to the interior of the mixing cylinder, and the mixing cylinder is also provided with a plurality of vents, the vents being connected to the interior of the mixing tube and the interior of the mixing cylinder respectively.

[0007] Preferably, the vent is provided with a guide plate, which is inclined and extends upward into the mixing pipe to form an inner extension.

[0008] Preferably, the lower end of the guide plate extends downward beyond the mixing tube to form an outer extension.

[0009] Preferably, the mixing cylinder is rotatably connected to the steam pipe, and the mixing cylinder is fixed with a horizontal vent rod, which is provided with vent holes.

[0010] Preferably, all the vent holes are located on one side of the horizontal vent rod.

[0011] Preferably, the rotating cylinder has an inverted conical structure.

[0012] Preferably, the surface of the steam pipe is provided with a heat insulation layer.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] 1. By utilizing the multiple vents in the mixing tube, the steam can be dispersed, allowing it to mix better with water and thus improve the heat exchange effect.

[0015] 2. By stirring with a horizontal venting rod, the mixing effect of steam and water is improved on the one hand, and the contact surface between the mixing pipe and water is increased to increase the heat exchange rate on the other hand. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0022] This application discloses a hybrid heater.

[0023] A mixing heater includes a mixing tube 1 with a water inlet pipe 3 connected to one side, allowing water to be heated to enter the mixing tube 1 through the water inlet pipe 3. A steam pipe 2 is connected to the upper end of the mixing tube 1, allowing steam to be introduced into the mixing tube 1. A mixing cylinder 5 is installed inside the mixing tube 1. An outlet pipe 4 is connected to the end of the mixing tube 1 furthest from the water inlet pipe 3. When water and steam are mixed in the mixing cylinder 5, hot water is formed and exits through the outlet pipe 4 for use. A heat insulation layer is provided on the surface of the steam pipe 2 to reduce heat loss and allow steam to enter the mixing tube 1 at a higher temperature.

[0024] The mixing tube 1 is hollow inside, and the steam pipe 2 is connected to the interior of the mixing cylinder 5. The mixing cylinder 5 is also provided with multiple vents 51, which are connected to the interior of the mixing tube 1 and the interior of the mixing cylinder 5, respectively. After the steam enters the mixing cylinder 5, it exits from the vents 51. The multiple vents 51 can disperse the steam, allowing it to fully mix with the water in the mixing tube 1, thereby improving the heat exchange efficiency.

[0025] A guide plate 52 is provided at the bottom of the vent 51, and the guide plate 52 is inclined outward from top to bottom. The upper end of the guide plate 52 extends upward into the mixing tube 1 to form an inner extension 53. The inner extension 53 can guide the steam, allowing the steam to exit from the vent 51 more easily. The lower end of the guide plate 52 extends downward out of the mixing tube 1 to form an outer extension 54. The outer extension 54 can contact the water inside the mixing cylinder 5. The guide plate 52 is preferably made of a material with good heat transfer effect, thereby further improving the heat exchange effect.

[0026] A horizontal vent rod 6 is fixed to the mixing cylinder 5, and the horizontal vent rod 6 is provided with vent holes 61. All vent holes 61 are located on one side of the horizontal vent rod 6. The mixing cylinder 5 is rotatably connected to the steam pipe 2, and steam will exit through the vent holes 61 on the horizontal vent rod 6. Since the vent holes 61 are located on one side of the horizontal vent rod 6, the reaction force generated by the steam exiting through the vent holes 61 causes the mixing cylinder 5 to rotate. This gives the horizontal vent rod 6 a stirring effect, improving the mixing of steam and water for better heat exchange. Furthermore, the horizontal vent rod 6 can also be made of a material with a high heat transfer coefficient, allowing for heat exchange between the water and the horizontal vent rod 6 during the stirring process. This further enhances the heat exchange effect.

[0027] The rotating cylinder has an inverted conical structure, which allows steam to easily exit from the vent 51.

[0028] The implementation principle of the embodiment is as follows: by utilizing the rotation of the mixing tube 1 and the dispersion of steam, the steam can be further mixed with water to improve the heat exchange effect.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
