Advantages of Immersed Thick Film Liquid Heaters (HVCH)
and Single-Sided Thick Film Liquid Heaters
| No. | Type | Single-Sided Thick Film Liquid Heater | Immersion Thick Film Liquid Heater | Immersion Advantages |
| 1 | Thermal efficiency | 90% of the heat on the heating plate is transferred to the coolant from one side, resulting in heat loss. | ≥98% of the heating plate is immersed in coolant, eliminating heat loss. | Energy-saving, improved mileage |
| 2 | Heating plate operating temperature | 230°C | 170°C | The heating plate operates at a low temperature and offers high reliability. |
| 3 | operating temperature | The electrical and water chambers are connected, which can easily cause condensation and insulation failure. | Complete isolation between the electrical and water chambers prevents condensation. | No condensation, eliminating insulation issues. |
| 4 | Eliminates air bleed valve | Equipped with a breather valve. | No vent valve required. | No vent valve required. |
| 5 | Eliminates fins | Heating plate + brazed fins, U-shaped flow channel. | S-shaped flow channel on the heating plate. | Reduced cost by approximately 40 yuan per unit. |
| 6 | Sealed | Large sealing rings are prone to aging and cracking. | Laser welding. | Mitigates the risk of water leaks. |
| 7 | Patented | BorgWarner patent | Independent patent. | Can be exported overseas without concerns about patent infringement. |
