Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically to a heating, ventilation and air conditioning energy-saving heat exchange device. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is a component of a building, encompassing heating, ventilation, and air conditioning. The term HVAC is a combination of these three functions. Heat exchange refers to the transfer of heat between two fluids, and is a unit operation within the heat transfer process. In traditional heat exchange devices, most are plate heat exchangers. During the heat exchange process, some heat exchangers require power, which increases operating costs.

[0003] In response, announcement number CN218723352U discloses a high-efficiency HVAC energy-saving and environmentally friendly heat exchange device, including a liquid injection tank, a coolant injection tank, a heat exchange tank, a coolant discharge tank, and a liquid discharge tank. These tanks are fixedly connected from top to bottom. The liquid injection tank has a liquid injection port at its top center and a coolant injection port on its top left side. A coolant injection pipe is fixedly connected inside the liquid injection tank directly below the coolant injection port. Multiple liquid injection pipes are also fixedly connected inside the coolant injection tank. This high-efficiency HVAC energy-saving and environmentally friendly heat exchange device features threaded plates and cooling pipes, enhancing heat dissipation and providing high strength. It does not contain electronic components, requires no power supply, and saves costs.

[0004] While the existing power-free heat exchange devices mentioned above achieve good energy-saving effects, they still have the following shortcomings in use: Although multiple cooling pipes are set up for heat exchange, there are inevitably large gaps between adjacent cooling pipes. The cold water flowing spirally downward between two adjacent cooling pipes cannot effectively achieve uniform contact for heat absorption and exchange. When used in a state where both water and high-temperature medium are flowing, the heat exchange uniformity and efficiency are poor. In view of this, this application proposes a heating and ventilation energy-saving heat exchange device to solve the above-mentioned problems. Utility Model Content

The multiple heat dissipation fins effectively increase the contact area and reduce dead zones. Combined with the automatic rotational and scattered spraying method when cold water is supplied, this facilitates effective and uniform heating of water over a large area during dual-medium flow applications, achieving uniform and efficient heat exchange.

[0033] The round box 2 has its bottom set as an outlet and is embedded and fixed to the top of the heat exchange box 1;

[0034] The water jet drive assembly is connected and fixed to the top of the round box 2, and a water inlet pipe 301 is connected and fixed to the front side of its top.

[0035] The swirling spray assembly is sealed and rotated inside the round box 2 and fixedly connected to the water jet swirling drive assembly. The water jet swirling drive assembly is used to automatically drive the swirling spray assembly to rotate when water is supplied through the water inlet pipe 301. The swirling spray assembly is used to swirlingly spray the supplied water downwards when rotating. The scattered spraying method formed by the swirling spray further enhances the contact effect and uniformity with multiple heat dissipation fins 105.

[0036] In this embodiment, a drain valve is fixedly connected to the bottom left side of the heat exchange box 1, and a water outlet pipe is fixedly connected to the left end of the drain valve for connecting to an external discharge pipe to allow the water for heat exchange to flow outward. The heat exchange box 1 consists of a box body with an open top and a top cover fixedly installed on its top by four bolts. A round box 2 is embedded and fixed on the top of the top cover, wherein the top of the top cover has a circular mounting hole that is fixedly connected to the outside of the round box 2.

[0037] Furthermore, such as Figure 2 and 3 As shown, the water jetting drive assembly includes a rectangular box 3, a baffle 4, a rotating shaft 403, multiple water turbine blades 404, a small bevel gear 402, and a large bevel gear 401.

The left side and bottom of the baffle 4 are both set as openings and are fixedly connected to the right side of the rectangular box 3 and the top of the circular box 2, respectively. The rotating shaft 403 is rotatably embedded in the inner wall of the right side of the rectangular box 3. Multiple water turbine blades 404 are fixedly connected to the outside of the rotating shaft 403 in a ring with equal spacing. The right end of the rotating shaft 403 extends into the baffle 4 and is fixedly connected to the left side of the small bevel gear 402. The large bevel gear 401 meshes with the top of the small bevel gear 402. The water inlet pipe 301 is fixedly connected to the front side of the top of the rectangular box 3 and is vertically aligned with the front water turbine blades 404.

[0038] In this embodiment, a circular through hole is provided on the right inner wall of the rectangular box 3, and a first sealing bearing is fixedly fitted inside the circular through hole. A first bearing is fixedly connected to the left inner wall of the rectangular box 3. The inner ring of the first bearing and the inner ring of the first sealing bearing are both fixedly fitted to the outer side of the rotating shaft 403, so as to achieve the effect of sealing and rotating the rotating shaft 403. A rectangular fitting hole is provided on the top left side of the circular box 2, which is fixedly connected to the outer side of the rectangular box 3.

[0039] In this embodiment, through the cooperation of rectangular box 3, protective cover 4, rotating shaft 403, multiple water turbine blades 404, small bevel gear 402 and large bevel gear 401, when water is supplied by connecting the water inlet pipe 301 to the external water supply pipe, the water impacts the front water turbine blades 404 downwards. Under the impact force, the front water turbine blades 404 rotate downwards and drive the rotating shaft 403 to rotate. The rotating shaft 403 drives the other multiple water turbine blades 404 to rotate in sequence to the front to be impacted and continue to rotate. The water then enters the circular box 2 downwards. The rotation of the rotating shaft 403 drives the small bevel gear 402 to rotate, and the small bevel gear 402 drives the large bevel gear 401 to rotate.

[0040] Furthermore, such as Figure 2 and 3 As shown, the swirling spray assembly includes a connecting shaft 203 and a rotating box 201. The rotating box 201 is sealed and rotatably fitted inside the round box 2. Three drain pipes 202 are connected and fixed on both sides of the bottom of the rotating box 201. The top of the rotating box 201 is set as an opening. The bottom end of the connecting shaft 203 is fixedly connected to the middle of the bottom inner wall of the rotating box 201. The round box 2 is sealed and rotatably fitted on the connecting shaft 203. The top end of the connecting shaft 203 is fixedly connected to the bottom of the large bevel gear 401.

[0041] In this embodiment, all six drain pipes 202 are located above multiple heat dissipation fins 105; a second sealing bearing is fixedly fitted inside the circular box 2, and the inner ring of the second sealing bearing is fixedly fitted to the outer side of the rotating box 201, which achieves the effect of sealing and rotating the rotating box 201; a circular hole is opened at the top of the circular box 2, and a third sealing bearing is fixedly fitted inside the circular hole, and the inner ring of the third sealing bearing is fixedly fitted to the outer side of the connecting shaft 203, which achieves the effect of sealing and rotating the connecting shaft 203.

[0042] In this implementation scheme, the connecting shaft 203, rotating box 201, and six drain pipes 202 work together. When the large bevel gear 401 rotates, the connecting shaft 203 drives the rotating box 201 to rotate. The rotating box 201 drives the six drain pipes 202 to rotate. Water entering the circular box 2 flows downward into the rotating box 201, and then is dispersed downward through the rotating six drain pipes 202. The dispersed spraying method formed by the rotating and dispersed spraying further enhances the contact effect and uniformity with the multiple heat dissipation fins 105, thereby further improving the heat exchange uniformity and efficiency, and improving the heat exchange effect. In addition, the method of using hydraulic power to automatically realize the rotating and dispersed spraying to enhance the heat exchange efficiency and uniformity does not require a separate electric rotary drive device, which has good energy-saving application advantages.

[0043] It should be noted that: the heat conduction coil 104 is preferably made of copper; the heat dissipation fins 105 are preferably made of aluminum; the rectangular box 3, the rotating shaft 403, the water wheel blade 404, the round box 2, the connecting shaft 203, the rotating box 201 and the drain pipe 202 are all preferably made of stainless steel.

[0044] The usage method of this embodiment is as follows: When using the HVAC energy-saving heat exchange device, the high-temperature HVAC fluid medium enters the left-side aggregation box 103 through the heat medium inlet pipe 101, then flows into multiple heat-conducting coils 104, and then gathers to the right in the right-side aggregation box 103. It then flows through the heat medium outlet pipe 102 to the externally connected heat medium delivery pipeline, achieving the effect of the heat medium being divided into multiple streams within the multiple heat-conducting coils 104. These multiple streams of heat medium heat the multiple heat-conducting coils 104, and the multiple heat-conducting coils 104 heat the multiple heat dissipation fins 105. The inlet pipe 301 connects to the external... When water is supplied through the water supply pipe, the water impacts the front water impeller 404 downwards. Under the impact force, the front water impeller 404 rotates downwards, driving the rotating shaft 403 to rotate. The rotating shaft 403 drives multiple other water impellers 404 to rotate sequentially to the front, where they are continuously impacted and rotated. The water then flows downwards into the circular box 2. The rotation of the rotating shaft 403 drives the small bevel gear 402 to rotate, which in turn drives the large bevel gear 401 to rotate. When the large bevel gear 401 rotates, it drives the rotating box 201 to rotate via the connecting shaft 203. The rotating box 201 then drives the six drain pipes 202 to rotate. Water entering the circular box 2 flows downwards into the rotating box 201, and then is dispersed downwards through six rotating drain pipes 202. This dispersed spraying method evenly and effectively distributes cold water onto multiple heat dissipation fins 105 and multiple heat-conducting coils 104. The heat dissipation effect of the multiple heat dissipation fins 105 is further enhanced during heat exchange with the heat-conducting coils 104. Furthermore, the effective dispersed contact between the heat dissipation fins 105 and the dispersed water allows heat to be rapidly dissipated over a larger area of ​​the multiple heat dissipation fins 105. The water is quickly dispersed and mixed into the water, enhancing heat exchange efficiency and further improving the contact effect and uniformity with multiple heat dissipation fins 105. The multiple heat dissipation fins 105 effectively increase the contact area and reduce dead zones. Combined with the water-powered automatic rotating and scattering spraying method when cold water is supplied, it facilitates effective and uniform heating of water over a large area during dual-medium flow applications, achieving uniform and efficient heat exchange and improving heat exchange uniformity and efficiency. In addition, the water-powered automatic rotating and scattering spraying method enhances heat exchange efficiency and uniformity without the need for a separate electric rotary drive device, which has good energy-saving application advantages.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
