Detailed Description

The technical scheme of the utility model is further specifically described below through specific embodiments and with reference to the accompanying drawings.

Example 1: as shown in fig. 1-2, the aluminum-based film heater with the runner is mainly formed by integrally extruding a rectangular aluminum heating substrate 1 with the runner, and an insulating layer 2, a heating layer 3 and a protective layer 4 are sequentially printed and sintered on two sides of the substrate 1 from the surface to the outside. The insulating layer 2 can prevent the aluminum heating substrate 1 from being electrified when the heater is powered on; the heating layer 3 is used for heating the substrate 1, so that water in the substrate 1 is heated through heat transfer; the protective layer 4 is mainly used for protecting the heating layer 3 from being damaged by external factors, prolonging the service life of the heating layer 3, and simultaneously playing a certain role in protecting the insulating layer 2. One side of the base plate 1 is provided with a water inlet hole 7 and a water outlet hole 8, and an S-shaped runner 9 is arranged inside the base plate 1 to communicate the water inlet hole 7 with the water outlet hole 8.

Particularly, the heating layer 3 is in an S-shaped strip shape, and the S-shaped flow channel 9 in the substrate 1 is correspondingly arranged with the S shape of the heating layer 3, so that the heat generated by the heating layer 3 can be maximally transferred into the flow channel, the heat utilization rate is higher, and the heating efficiency of the heater is increased; the electrode plates 5 are arranged at two ends of the S-shaped heating layer 3 and used for being connected with an external heating power supply, and in the actual heating process, the resistance of the bending part of the S-shaped heating layer 3 is higher than that of the straight section, so that after the heating layer 3 is electrified, the bending part of the heating layer 3 is easily overheated locally, and the heating layer 3 is burnt out, therefore, a conductive sheet 6 is required to be added at the bending part of the heating layer 3 and used for shorting the bending part of the heating layer 3, so that the local overheating is eliminated, meanwhile, the water in the substrate 1 is heated more uniformly, and the heating effect is better. In order to achieve better heating, the initial section of the heating layer 3 (i.e. at one end of the water inlet 7) is designed to be a certain distance from the water inlet 7, so that a larger buffer flow is given to cold water, the deformation of the heating substrate 1 caused by cold and hot impact is prevented, and each heater can work in a single-sided or double-sided heating mode according to practical situations because the heating plates and the electrodes on the two sides of the substrate 1 are independent.

In the use process, the temperature of the heater cannot be controlled, so that a temperature measuring area 10 can be further arranged at the middle bending part of the S-shaped heating layer 3, the temperature measuring area 10 can be provided with a temperature control NTC thermistor 11, the heating substrate 1 is monitored in real time, and the user can take measures in time when the temperature is abnormal.

Finally, the water inlet 7 and the water outlet 8 of the heater are connected with the water pipe 17 through the pagoda joint 16, the pagoda joint 16 can be connected with the heating substrate 1 by threads, the disassembly of the water pipe 17 and the pagoda joint 16 is convenient, and the water inlet 7 and the water outlet 8 of the heater can be cleaned regularly. Meanwhile, according to actual requirements, a water adhesive tape is added at the joint, or other modes such as welding are adopted, so that the phenomenon of water leakage is prevented.

Example 2: the difference between the aluminum-based film heater with the flow channel and the embodiment 1 is that the S-shaped flow channel 9 in the base plate 1 is replaced by a linear flow channel 13, two ends of the flow channel are connected by a collecting pipe 14, wherein one collecting pipe 14 is provided with a water inlet 7, and the other collecting pipe 14 is provided with a water outlet 8; in the scheme, after the S-shaped flow channel 9 is replaced by the linear flow channel 13, the water flowing path is shortened, and under the condition of the same water flow rate and the same volume of water, the heating time length is shortened, so that more needed hot water can be obtained more quickly; in addition, due to the change of the flow channel, namely the S-shaped flow channel 9 is changed into the linear flow channel 13, the flow hole processing procedure at the bending position in the S-shaped flow channel 9 is reduced, and the production cost is reduced.

Example 3: a double-sided heated aluminum-based film heater with flow channels as shown in FIG. 4 is a combination of the applications of examples 1-3. The difference from embodiment 3 is that a single heating substrate 1 is added to a plurality of heating substrates 1, meanwhile, the collecting pipe 14 is replaced by a collecting plate 15 with higher height, a plurality of heating substrates 1 are arranged between two collecting plates 15 in a stacked manner, the two collecting plates 15 are communicated through flow channels inside the substrate 1, and finally, water inlet holes 7 and water outlet holes 8 are respectively arranged on the two collecting plates 15 in a diagonal up-down manner, wherein the water inlet holes 7 are required to be arranged at the bottom of one collecting plate 15, and the water outlet holes 8 are required to be arranged at the top of the other collecting plate 15. The water outlet 7 and the water inlet 8 can be arranged on the same side or on opposite sides.

The following two schemes were produced in combination with the differences of examples 1 and 2.

Scheme one: the flow channels in the plurality of substrates adopt S-shaped flow channels 9. When water enters the water inlet holes 7, the water level gradually rises and sequentially passes through the heating substrates 1 from low to high, air in the heating substrates 1 is discharged from the water outlet holes 8, and finally hot water is output from the water outlet holes 8. The scheme ensures the time length of enough heating due to longer water flow path, so that smaller power can be adopted, the number of heaters is increased, the purpose of large-flow heating is realized, and the energy consumption is greatly saved.

Scheme II: the flow channels in the plurality of substrates adopt the straight-line flow channel 13. When the water inlet holes 7 are filled with water, the water level gradually rises and sequentially passes through the heating substrates 8 from low to high, air in the heating substrates 1 is discharged from the water outlet holes 8, and in the heating process, all parallel straight flow channels 13 of the same heating substrate 1 simultaneously flow water and heat the water, and finally the water is output from the water outlet holes 8. This solution allows more hot water to be obtained faster because the water flow path is shorter.
