Description

Technical Field

[0001] This application relates to the field of automotive heating equipment technology, specifically to an automotive liquid heater. Background Technology

[0002] Existing vehicles generally suffer from several problems in low winter temperatures. Among these, gasoline-powered vehicles experience difficulty starting in cold weather, while the precipitous drop in range for new energy vehicles in winter is a major industry pain point. Heating energy consumption accounts for a significant proportion of this winter range loss, approximately 30%. Other issues include high power consumption for parking heaters. Traditional heating products are ineffective and have limited applications, only suitable for gasoline-powered vehicles. While traditional PTC heaters are used, they suffer from drawbacks such as small heating area, low efficiency, high energy consumption, and large size. Summary of the Invention

A circuit board 18 is installed at the bottom of the fan assembly 2, and a motor, fan, etc. are installed inside. The fan is controlled by the circuit board 18 to blow air. An end cap 4 is inserted into one end of the heating chamber 1, and a flow cavity 3 is formed between the heating chamber 1 and the end cap 4. The fan assembly 2 is connected to the flow cavity 3. Heating components are arranged around the inner walls of the heating chamber 1 and the end cap 4. A heating cavity 5 is arranged around the flow cavity 3 inside the heating chamber 1. A water inlet pipe 6 and a water outlet pipe 7 are connected to the top of the heating chamber 1. Both the water inlet pipe 6 and the water outlet pipe 7 are connected to the heating cavity 5. The fan assembly 2 blows air to send the externally introduced hot air into the flow cavity 3 for circulation. After the heating components come into contact with the hot air, they heat the entire heating chamber 1, thereby heating the external heating cavity 5. The cold water sent in by the water inlet pipe 6 is circulated and heated in the heating cavity 5 and then flows out from the water outlet pipe 7, thus achieving the heating purpose.

The first heating plate 8, the second heating plate 9, and the third heating plate 10 are staggered and arranged in a stepped manner. The lengths of the first heating plate 8, the second heating plate 9, and the third heating plate 10 increase sequentially. The staggered and stepped arrangement maximizes the contact area of ​​each heating plate, thereby improving the heating effect. The bottom of the heating chamber 1 is provided with an air inlet pipe 20 and an air outlet pipe 11, which are connected to the flow chamber 3. The air inlet pipe 20 is also connected to an external heating system. The external heating system can send steam from the air inlet pipe 20 into the heating chamber 1, and then blow it into the flow chamber 3 through the fan assembly 2. The fan assembly 2 is provided with a wind pressure hole 12 on one side. After the air enters the flow chamber 3, it is discharged from the air outlet pipe 11.

[0030] In some embodiments, such as Figures 6-8 As shown, the heating chamber 1 has an opening on one side with an insertion slot 13, and the end cover 4 has an insertion part 14 corresponding to the insertion slot 13. The heating chamber 1 and the top of the fan assembly 2 are equipped with an upper cover 15. Below the upper cover 15, on one side of the end cover 4, a sealing cover 19 is installed. The heating chamber 1 has multiple positioning holes 16, and the sealing cover 19 has multiple positioning seats 17. The sealing cover 19 is fixed to the heating chamber 1 by the positioning seats 17 and the positioning pins, and the top is fixed to the upper cover 15 by a buckle.
