Description

Technical Field

[0001] This utility model belongs to the field of new energy vehicle technology, specifically, it relates to a novel integrated heating device for a compressor. Background Technology

[0002] With the rapid development of the new energy vehicle industry, in-vehicle heating in winter has become a core requirement affecting user experience. Traditional gasoline vehicles can utilize the waste heat from the engine to heat the passenger compartment, while new energy vehicles (especially pure electric vehicles) have no engine waste heat to utilize and must rely on electric heating devices to achieve in-vehicle heating. Membrane electric heating devices have become the core choice due to their unique advantages: fast heating speed, high safety, and stable provision of heating heat to the vehicle interior. In the air conditioning system of new energy vehicles, the compressor mainly undertakes the refrigerant compression function of the refrigeration cycle or heat pump system. However, in existing technologies, the compressor and PTC heating device are generally set up separately: they are designed independently and installed separately in the vehicle chassis or engine compartment, requiring dedicated mounting brackets, fluid delivery pipelines, and electrical control circuits, and each operates independently to achieve refrigeration / heat pump and heating functions. This design also has the following problems in use: The compressor and heater are designed and installed independently (usually in different locations on the chassis or in the engine compartment), each requiring dedicated mounting brackets and space, thus taking up valuable vehicle chassis / engine compartment space and increasing the complexity of the assembly layout. The separate design requires separate cooling fluid piping (inlet / outlet pipes) and high-voltage electrical wiring harnesses and control lines for the heater. This increases the number of parts, material costs (piping, wiring harnesses, connectors), assembly time, and complexity; the dispersed installation locations may increase the complexity and time required to inspect and replace any component (compressor or heater).

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0004] Therefore, in order to solve the above problems, this utility model provides a novel integrated heating device for a compressor. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a new type of integrated heating device for compressors.

[0006] The objective of this utility model can be achieved through the following technical solutions: A novel integrated heating device for a compressor includes a compressor, wherein a heating module is integrated on one side of the compressor; The heating module includes a housing with an irregularly shaped water channel inside.

[0019] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments: Please see Figure 1 According to an embodiment of the present utility model, a novel integrated heating device for a compressor includes a compressor 1, a heating module 2 integrated on one side of the compressor 1, the heating module 2 being an independent unit integrated on the compressor 1, responsible for electrically heating the coolant, achieving physical integration, and sharing installation, space, and some pipelines / lines; Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The heating module 2 includes a housing 201. Inside the housing 201 is a shaped water channel 203 with a serpentine, meandering structure to increase the water flow path length and improve the heat exchange area. The side wall of the housing 201 has an inlet 204 and an outlet 206, located at the inlet and outlet of the shaped water channel 203, respectively. The inlet 204 and outlet 206 connect to external coolant pipes, guiding coolant into / out of the shaped water channel 203, thus connecting to the vehicle's cooling circulation system. A heat transfer plate 208, made of stainless steel, is mounted above the shaped water channel 203 and fixedly connected to the housing 201 with screws. Several resistors 209 are fixedly installed above the heat transfer plate 208, evenly arranged along the length of the heat transfer plate 208 with equal spacing between adjacent resistors. The resistors are connected by conductors and covered with insulation on both sides. The membrane and heat transfer plate 208 are located above the irregular water channel 203, efficiently transferring the heat generated by the resistor 209 to the wall of the irregular water channel 203 and the coolant, thereby heating the coolant. The resistor 209 is the core heating element that converts electrical energy into heat energy. The electrothermal conversion speed is fast, achieving rapid heating. A control circuit board 213 is installed below the shell 201. An electrode 212 is also installed on the heat transfer plate 208. The electrode 212 consists of an electrode plastic coating and an electrode. The electrode plastic coating covers the non-connecting section of the electrode, achieving electrical insulation and sealing protection. One end of the electrode is connected to the resistor 209, and the other end of the electrode is connected to the control circuit board 213. The control circuit board 213 adjusts the heating power according to the demand and optimizes energy consumption. The electrode 212 is the electrical path connecting the resistor 209 and the control circuit board 213, which transmits current to the resistor 209, thereby causing the resistor 209 to heat up.

[0020] Please see Figure 1 , Figure 2 and Figure 4 An end cap 202 is installed on the housing 201. The end cap 202 can seal the housing 201, thereby protecting the structure inside the housing 201.

[0021] Please see Figure 5 One end of the inlet 204 is connected to the inlet pipe 205, and one end of the outlet 206 is connected to the outlet pipe 207. The inlet pipe 205 and the outlet pipe 207 are pipe sections directly connected to the inlet 204 and the outlet 206, which facilitates on-site installation or provides a specific route and simplifies the connection with the vehicle's piping.

[0022] Please see Figure 4The heat transfer plate 208 has a first mounting groove 210 and the housing 201 has a second mounting groove 211. The positions and shapes of the first mounting groove 210 and the second mounting groove 211 are matched. The electrode 212 is installed inside the first mounting groove 210 and the second mounting groove 211. The first mounting groove 210 and the second mounting groove 211 together form a cavity to accommodate the electrode 212, ensuring that the electrode 212 is installed in an accurate position and limiting the displacement of the electrode 212, thus ensuring the reliability of the connection.

[0023] Please see Figure 4 A first sealing ring 214 is provided at the connection between the housing 201 and the end cover 202. The first sealing ring 214 isolates the heating film device cavity from the outside world, ensuring the internal sealing of the heating module 2. A second sealing ring 215 is provided at the connection between the housing 201 and the outer shell of the compressor 1. The second sealing ring 215 isolates the control circuit board 213 from the outside world, ensuring the sealing of the integrated interface and preventing external corrosion of the compressor or electrical components. The first sealing ring 214 and the second sealing ring 215 are made of steel frame and NBR composite material.

[0024] Please see Figure 4 The end cap 202, the first sealing ring 214, the housing 201, the second sealing ring 215 and the outer shell of the compressor 1 are connected and fixed by multiple bolts 216. The bolts 216 fasten the end cap 202, the first sealing ring 214, the housing 201, the second sealing ring 215 and the outer shell of the compressor 1 into a whole, which is the key to achieving modular integration and reliable fixation. At the same time, they can press the sealing ring to ensure the sealing effect.

[0025] The working principle of a novel integrated heating device for a compressor is as follows: Low-temperature coolant from the vehicle's heating system enters the irregularly shaped water channel 203 of the heating module through the inlet pipe 205 and inlet 204. The control circuit board 213, according to instructions from the air conditioning control unit, supplies a controllable current to the electrode component 212. The current is transmitted through the electrode component 212 to the resistor 209, which efficiently converts electrical energy into heat energy. The heat generated by the resistor 209 is first transferred to the stainless steel heat transfer plate 208 in close contact with it. The heat transfer plate 208, with its good thermal conductivity and a certain area, rapidly diffuses the heat source, forming a relatively uniform surface heat source. The heat is transferred from the heat transfer plate 208... The heat plate 208 conducts heat to the wall of the irregular water channel 203. The low-temperature coolant flows in the irregular water channel 203. Its tortuous path prolongs the time it takes to flow through the heating area and enhances fluid turbulence. This allows the coolant to fully absorb the heat transferred from the water channel wall. The heated high-temperature coolant flows out of the heating module 2 through the outlet 206 and the outlet pipe 207 and is delivered to the vehicle's heater core. The high-temperature coolant flows through the heater core, and the fan blows air through the heater core. The air is heated and then sent into the cab to provide heating. The control circuit board 213 continuously monitors key parameters and precisely controls the water temperature by adjusting the power output to the resistor.
