Description

Technical Field

[0001] The utility model relates to a heat dissipation device, in particular to a heat dissipation device of a water heater, belonging to the technical field of water heaters. Background Art

[0002] A water heater is a device specially used to heat water. Its main components include: furnace body, heating furnace, burner, flue, water pump, controller, etc. Among them, the furnace body is the most basic component of the water heater. It is usually made of steel plate, and a special coating is used inside to prevent corrosion.

[0003] After searching, a Chinese patent with publication number CN211503216U discloses a water heater, including: a first heat exchanger, the inlet end of which is connected to a first return pipe; a domestic hot water heat exchange system, the inlet end of which is connected to the outlet end of the first heat exchanger; and a shunt controller, which is arranged at the outlet end of the domestic hot water heat exchange system and is suitable for dividing the outlet end of the domestic hot water heat exchange system into two paths and controlling the flow of the two paths respectively, wherein the outlet end of one path is connected to the first return pipe, and the outlet end of the other path and the first return pipe are connected to the heating circuit. The domestic hot water heat exchange system is connected in series with the heating circuit, and the shunt controller can realize the simultaneous supply of domestic hot water and heating hot water without using a three-way regulating valve, thereby reducing costs. At the same time, when the water heater provides the heating function, the domestic hot water system is in standby mode. When the domestic hot water function is used, there is no need to adjust the flow direction of the hot water pipe, which reduces the regulation of the shunt controller, thereby reducing the failure rate of the shunt controller.

[0004] Although the above solution does not require adjustment of the flow direction of the hot water pipe, reducing the regulation of the shunt controller, thereby reducing the failure rate of the shunt controller, the hot water boiler in the above patent is difficult to dissipate heat effectively, and excessive temperature will cause the electronic control motherboard to malfunction; for this reason, we provide a heat dissipation device for a hot water boiler to solve the above problems.

[0025] The embodiment of the utility model provides a heat dissipation device for a water heater.

[0026] See also Figure 1 , including an electronic control mainboard body 1 and a component protection shell 2, one side of the component protection shell 2 is fixedly connected to one side of an external mounting plate 14, and an expansion screw hole is opened on the external mounting plate 14. The setting of the external mounting plate 14 can directly install the heat dissipation device through the expansion screws, thereby shortening the time required for the installation of the heat dissipation device and improving the installation efficiency.

[0027] See also Figure 1 The electric control main board body 1 is welded with a coil body 9. Both the electric control main board body 1 and the coil body 9 are prior arts and will not be described in detail. The setting of the coil body 9 can effectively heat the water body, and under the control of the electric control main board body 1, the degree of heating can be freely adjusted.

[0028] See also Figure 1 The coil body 9 is sleeved on the outer circumference of the glass water-blocking tube 10. The setting of the glass water-blocking tube 10 can effectively transfer heat and ensure that the water body is not easily polluted by the outside world, which is convenient for observing the water condition.

[0029] See also Figure 1 , Figure 2 and Figure 4 The glass water-blocking tube 10 is inserted into the top of the bottom position-controlling shell 11, and a silicone sealing pad 15 is arranged between the bottom position-controlling shell 11 and the glass water-blocking tube 10. The silicone sealing pad 15 has the same specifications as the silicone sealing pad 2 18. The arrangement of the silicone sealing pad 15 and the silicone sealing pad 2 18 avoids water seepage at the junction between the glass water-blocking tube 10 and other components, thereby enhancing the flow effect of the water body.

[0030] See also Figure 2 The top of the bottom control shell 11 is fixedly connected to one end of the internal water pipe 12, and the outer circumferential surface of the internal water pipe 12 is sleeved with an external water pipe 13. The tight fit between the internal water pipe 12 and the external water pipe 13 can effectively lengthen the path of water flow, thereby ensuring that the water is heated and avoiding the situation where the water is not hot.

[0031] See also Figure 2 The top of the external water pipe 13 is fixedly connected to the bottom of the water control module 16, and the top of the water control module 16 is fixedly connected to the bottom of the top control shell 17. The setting of the water control module 16 can effectively guide the water body and ensure that the water body flows along a predetermined route, thereby ensuring that the water body is not easily blocked.

[0032] See also Figure 1 and Figure 2 A glass water-blocking tube 10 is inserted into the bottom of the top position-controlling shell 17, and a silicone sealing gasket 18 is arranged between the glass water-blocking tube 10 and the top position-controlling shell 17. The bottom of the external water pipe 13 is fixedly connected to the top of the bottom position-controlling shell 11. The arrangement of the bottom position-controlling shell 11 can effectively ensure the stability of the external water pipe 13, so that the external water pipe 13 is not prone to tilt.

[0033] See also Figure 1 and Figure 3 A cooler body 3 is plugged into the interior of the component protection shell 2. The cooler body 3 is a prior art and will not be described in detail. The cooler body 3 can effectively take away the heat emitted by the electronic control motherboard body 1 through its own thermal conductivity when the water flows through the body. An external telescopic tube 4 is welded to the bottom of the cooler body 3. The setting of the external telescopic tube 4 can rotate the direction of the water outlet when connected to the external water pipe, which is more practical.

[0034] See also Figure 1 and Figure 3 The cooler body 3 and the electronic control main board body 1 are fixedly connected, which can effectively fix the cooler body 3 and prevent the cooler body 3 from sliding and falling off.

[0035] Working principle: By controlling the main body 1 of the electronic control motherboard, the coil body 9 can be gradually heated to heat the glass water-blocking tube 10. At this time, the water enters the cooler body 3 from the external telescopic tube 4, and then enters the bottom control shell 11 from the cooler body 3, so that the water flows from the bottom to the top in the internal water pipe 12. When the water reaches the highest point of the internal water pipe 12, it will flow from the top to the bottom in the external water pipe 13. The water enters the glass water-blocking tube 10 from the water hole reserved at the bottom of the external water pipe 13. At this time, the water flows from the bottom to the top through the water control module 16 and flows out from the water outlet at the top of the top control shell 17. The internal water pipe 12 and the external water pipe 13 are both located in the glass water-blocking tube 10. When the temperature in the glass water-blocking tube 10 rises, the water in the glass water-blocking tube 10, the internal water pipe 12 and the external water pipe 13 can be heated at the same time. At this time, the electronic control main board body 1 itself will also generate heat, and the heat will be conducted to the cooler body 3 itself. The unheated water will continuously flow in the cooler body 3, taking away the heat inside the cooler body 3, thereby effectively dissipating the heat of the electronic control main board body 1, avoiding the problem that the electronic control main board body 1 is in a high temperature state for a long time, which is prone to malfunctions.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
