Description

Technical Field

[0001] This utility model belongs to the field of vehicle-mounted water heater technology, specifically relating to a vehicle-mounted solar water heater. Background Technology

[0002] Traditional vehicle-mounted water heaters primarily use electric or diesel heating. Electric water heaters consume a large amount of electricity, requiring a high-powered vehicle generator for continuous power supply. Furthermore, they cannot provide a continuous hot water supply when multiple people are showering consecutively. Diesel-heated water heaters require a separate diesel tank or draw fuel from the vehicle's fuel tank, necessitating a continuous fuel supply during operation. Additionally, diesel-heated water heaters produce a significant amount of smoke during heating, causing environmental pollution.

[0003] Given the aforementioned existing technologies, it is necessary to change the traditional heating method of vehicle-mounted water heaters, and adopting an energy-saving and environmentally friendly hot water heating system is particularly important and urgent. To this end, the applicant has made beneficial designs, and the technical solution described below arose from this background. Utility Model Content

[0004] The objective of this utility model is to provide a vehicle-mounted solar water heater that changes the traditional heating method of vehicle-mounted water heaters. It adopts a water heater that obtains hot water through solar heating, and has advantages such as economy, convenience, safety, and environmental protection.

[0005] The present invention accomplishes its objective as follows: a vehicle-mounted solar water heater includes a solar panel, a heat exchange component, an insulated water tank, a controller, and a water supply component. The heat exchange component includes a coolant tank and a heat exchange pump. The coolant tank stores coolant, and the coolant tank and the heat exchange pump are connected by pipes. The key feature is that the heat exchange pump is connected to the solar panel via pipes, and the solar panel is connected to the insulated water tank via pipes. The insulated water tank is connected to the coolant tank and the water supply component via pipes. The controller is electrically connected to the heat exchange component and the insulated water tank. The controller controls the heat exchange pump to pump the coolant from the coolant tank into the heat exchange pipes inside the solar panel. After the solar panel collects heat, the heat from the solar panel is transferred to the insulated water tank. When showering, the water supply component is turned on to use the hot water from the insulated water tank.

[0006] In a specific embodiment of this utility model, multiple solar panels are provided. The solar panels are covered with aluminum alloy profiles and tempered glass on the outside and have heat exchange pipes inside. The reserved pipe interfaces are four-point copper tube optical ports.

[0007] In another specific embodiment of this utility model, the angle between the solar panel and the roof surface is adjusted by extending and retracting an electric push rod.

[0008] In another specific embodiment of this utility model, the capacity of the coolant tank is set to be no less than 2L.

[0009] In another specific embodiment of this utility model, the wall thickness of the insulated water tank is no more than 20mm.

[0010] In another specific embodiment of this utility model, the controller includes a water temperature detection component and a water temperature display component, wherein the water temperature detection component detects the temperature T0 of the solar panel and the temperature T1 of the insulated water tank 3.

[0011] In a further specific embodiment of this utility model, the water supply component is equipped with a self-priming pump, a shower valve, and a spray head. One end of the self-priming pump is connected to a pipe in an insulated water tank, and the other end is connected to a spray head via a pipe. A shower valve and a pressure switch are installed on the pipe connecting the self-priming pump and the spray head, and the start and stop of the self-priming pump are controlled by the pressure switch.

[0012] Due to the aforementioned structure, this utility model has the following beneficial effects: First, this water heater collects solar energy through a solar panel to heat the shower water in the insulated water tank, providing hot water for showering. This heating method overcomes the drawbacks of high power consumption in electric heating and environmental pollution from diesel heating, giving it advantages such as economy, convenience, safety, and environmental friendliness. Second, this water heater has a water temperature detection and display function. When the temperature difference between the solar panel and the insulated water tank reaches ∆T1, heat transfer is initiated; when the temperature difference is lower than ∆T2, heat collection is initiated, enabling automatic circulation and heat preservation. Third, this water heater also has a high-temperature protection function; when the temperature of the insulated water tank is too high, the automatic circulation and heat preservation function stops.

However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0018] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the positions shown in the corresponding figures. They are merely for the purpose of describing the technical solution provided by this utility model in conjunction with the figures and simplifying the description. Therefore, they should not be construed as a special limitation on the technical solution provided by this utility model.

[0019] Please see Figure 1 This utility model relates to a vehicle-mounted solar water heater, including a solar panel 1, a heat exchange component 2, an insulated water tank 3, a controller 4, and a water supply component 5. The heat exchange component 2 includes a coolant tank 21 and a heat pump 22. The coolant tank 21 stores coolant. The coolant tank 21 and the heat pump 22 are connected by pipes. The heat pump 22 is connected to the solar panel 1 through pipes. The solar panel 1 is connected to the insulated water tank 3 through pipes. One end of the insulated water tank 3 is connected to the coolant tank 21 through a pipe, and the other end is connected to the water supply component 5 through a pipe. The controller 4 is electrically connected to the solar panel 1, the heat exchange component 2, and the insulated water tank 3. The controller 4 controls the solar water heater to heat the shower water in the insulated water tank 3 during the day and to provide hot water for showering during showering.

[0020] Specifically, multiple solar panels 1 are provided; in this embodiment, four solar panels 1 are provided, such as... Figure 3 As shown. The solar panel 1 is externally covered with aluminum alloy profiles and tempered glass, and internally contains heat exchange pipes made of copper, with reserved pipe interfaces being 1 / 4-point copper tube ports. Figure 2 As shown, the angle between the solar panel 1 and the roof surface is adjusted by the extension and retraction of the electric push rod 11. Figure 2 In the middle, solar panel 1 is flipped to an angle of 12° with the roof surface, which can collect heat more effectively.

[0021] In this embodiment, the coolant tank 21 has a capacity of not less than 2L and is made of stainless steel. The heat exchange pump 22 has an operating pressure greater than or equal to 1.0 kg and a flow rate of 30 L / min. The coolant used is ethylene glycol, and the main body of the pipe is made of stainless steel corrugated pipe. During the circulation process, the coolant continuously carries the heat from the solar panel 1 into the insulated water tank 3.

[0022] The main body of the insulated water tank 3 is made of 06Cr19Ni10, i.e., 304 stainless steel, and the wall thickness of the tank is no more than 20mm.

[0023] The controller 4 includes a water temperature detection component and a water temperature display component. The water temperature detection component can detect the temperature T0 of the solar panel 1 and the temperature T1 of the insulated water tank 3. When the detected temperature difference between the solar panel 1 and the insulated water tank 3 is greater than or equal to ∆T1, for example, ∆T1=8℃, the controller 4 controls the heat exchange pump 22 to start automatically, carrying the heat from the solar panel 1 into the insulated water tank 3. When the detected temperature difference between the solar panel 1 and the insulated water tank 3 is less than or equal to ∆T2, for example, ∆T2=4℃, the controller 4 controls the heat exchange pump 22 to shut down automatically, waiting for the solar panel 1 to collect heat. In this embodiment, the structure of the controller 4 is not specifically limited; any controller in the prior art that can achieve the functions described in this case can be used.

[0024] The insulated water tank 3 also has a high temperature protection function: when the temperature of the insulated water tank 3 is higher than the set value, the controller 4 controls the automatic circulation insulation function to stop, and the circulation will be restarted only after the temperature of the insulated water tank 3 drops.

[0025] The water supply component 5 is equipped with a self-priming pump 51, a shower water valve 52, and a spray head 53. One end of the self-priming pump 51 is connected to the insulated water tank 3 via a pipe, and the other end is connected to the spray head 53 via a pipe. The pipe connecting the self-priming pump 51 and the spray head 53 is equipped with a shower water valve 52 and a pressure switch. The pressure switch controls the start and stop of the self-priming pump 51. When the temperature in the insulated water tank 3 is suitable, the shower water valve 52 can be opened for showering.

[0026] The entire working process of the vehicle-mounted solar water heater is as follows: The controller 4 controls the heat exchange pump 22 to pump the coolant in the coolant tank 21 into the heat exchange pipe inside the solar panel 1. After the solar panel 1 collects heat, the heat in the solar panel 1 is carried into the insulated water tank 3. When showering, the shower water valve 52 is opened to use the hot water in the insulated water tank 3.
