Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management system technology, specifically a quick-installation fast-heating electronic water pump. Background Technology

[0002] Because of the extremely low temperatures in winter, it is difficult for the batteries of new energy pure electric vehicles to be fully charged or discharged, resulting in a decrease in the driving range of new energy pure electric vehicles in low-temperature environments. New energy pure electric vehicles can generally solve the problem of reduced driving range by installing heaters to preheat the battery pack and bring it to the normal operating temperature. This also avoids damage to the battery pack caused by low-temperature charging. The battery pack heating system of new energy pure electric vehicles mainly uses PTC or thick film heaters, and the heat generated is transferred to the electric vehicle battery pack through antifreeze via an electronic water pump to preheat it and bring it to the normal operating temperature.

[0003] Currently, the commonly used thermal management solution is a heater + electric water pump. The heater is further divided into PTC route and HIC route. The advantages of PTC heater are stable temperature, high safety performance and low cost. The disadvantages are low energy efficiency, slow heat conduction, relatively low temperature control accuracy and large size. The advantages of HIC heater are high energy efficiency, fast heat conduction, precise temperature control and small size. The disadvantages are high manufacturing cost and the need for additional circuit protection measures to prevent overheating and short circuit. Regardless of the solution, the whole system has many components. Since the heater and electric water pump are two independent components, they need to be connected by pipelines. This not only increases the installation space requirements and manufacturing costs, but also increases the risk of leakage. The high cost and large space occupation do not conform to the development trend of energy conservation, emission reduction and lightweighting.

[0004] Therefore, we propose a quick-installation, rapid-heating electronic water pump to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this utility model is to provide a quick-installation, fast-heating electronic water pump to solve the problems mentioned in the background art, such as increased installation space requirements and manufacturing costs, increased leakage risks, high cost, large space occupation, and failure to meet the development trends of energy conservation, emission reduction, and lightweighting.

[0010] The motor stator assembly is installed inside the internal and external heating flow channel assembly.

[0011] The top outer ring of the motor stator assembly is equipped with a heating cylinder welding wire assembly.

[0012] Preferably, the control room assembly includes a rear cover sealing ring fitted to the bottom of the inner and outer heating channel assembly. A high-pressure connector body is installed on the top front surface of the inner and outer heating channel assembly, and a low-pressure connector body is installed on the right side of the inner and outer heating channel assembly.

[0014] The above-mentioned structural design facilitates effective sealing of the component connections through the rear cover sealing ring, high-pressure connector sealing ring, and low-pressure connector sealing ring. This effectively prevents water ingress that could damage the circuit and cause short circuits, thus improving the waterproof sealing effect. The waterproof vent cap effectively prevents condensation and frost from forming in the control room and balances pressure to reduce stress on the casing sealing strip.

[0015] Preferably, the pump head assembly includes a volute body mounted on top of the inner and outer heating flow channel assembly. An impeller rotor assembly is rotatably mounted inside the volute body. A wear-resistant gasket assembly is installed at the connection between the top of the impeller rotor assembly and the volute body. A volute sealing ring is installed at the connection between the bottom of the volute body and the inner and outer heating flow channel assembly. An isolation sleeve body is wrapped around the outer ring of the impeller rotor assembly. The top of the isolation sleeve body is fixedly connected to the top of the inner ring of the volute body.

[0016] The above-mentioned structural design facilitates effective isolation through the pump head assembly components, thereby improving the internal isolation effect and sealing performance of this quick-installation rapid heating electronic water pump.

[0017] Preferably, the heating cylinder wire bonding assembly includes a heating cylinder screen printing assembly fixedly installed on the top of the inner and outer heating flow channel assembly. A second screw is installed on the front side of the heating cylinder screen printing assembly. A waterproof cover is fitted around the outer ring of the second screw.

[0019] The design of the above structure enables the heating cylinder wire bonding assembly to heat the fluid over a large area, thereby achieving rapid temperature rise and improving the heating efficiency of the quick-installation rapid heating electronic water pump. At the same time, the sealing structure in the heating cylinder wire bonding assembly can effectively prevent liquid intrusion from causing short circuits and damage, thus improving the performance.

[0020] Preferably, the motor stator assembly includes a motor housing fixedly mounted on the top of the inner and outer heating flow channel assembly. The motor housing is located in the inner ring of the heating cylinder screen printing assembly, and the stator assembly is installed inside the motor housing.

[0021] The design of the above structure enables the stator assembly to limit the direction of rotation of the stator assembly, preventing radial rotation of the stator assembly and improving drive stability.

[0022] Preferably, the gap between the motor housing and the heating cylinder screen printing assembly forms an inner heating channel, and the gap between the heating cylinder screen printing assembly and the volute body forms an outer heating channel.

[0023] Preferably, the internal layout of the internal heating flow channel has three sets of downward spiral blades, and the inclination angle of the three sets of spiral blades is 120 degrees.

[0024] Preferably, the internal layout of the external heating flow channel has three sets of upward spiral blades, and the inclination angle of the three sets of spiral blades is 120 degrees.

[0025] The design of the above structure allows the fluid to be heated over a large area in conjunction with the internal and external heating channels, thereby improving heating efficiency. The spiral blades guide the fluid in a spiral manner, which helps the fluid to be heated evenly during the spiral flow process, thus improving heating uniformity.

[0026] Compared with the prior art, the beneficial effects of this utility model are: the quick-installation rapid heating electronic water pump combines the electronic water pump and the heater into a complete unit, which can not only reduce the installation size but also reduce the installation difficulty. At the same time, it can reduce manufacturing costs and reduce the use of intermediate transition pipes. The water pump inlet and outlet adopt quick-connect interface, which improves production efficiency compared with the traditional clamp installation.

[0027] 1. The control room assembly components can improve the connection and sealing between the high and low pressure plug body. The waterproof vent cap in the control room assembly components can prevent condensation and frost in the control room, balance the pressure and reduce the stress of the housing sealing strip. The pump head assembly components can effectively improve the wear resistance and help extend the service life.

[0028] 2. The internal and external heating flow channel assembly facilitates the stable installation of the heating flow channel body. The heating flow channel body, together with the heating cylinder welding assembly, can heat the fluid inside the heating flow channel body over a large area, improving heating efficiency. Furthermore, the heating cylinder welding assembly can effectively prevent short circuits caused by contact between exposed parts and liquid, and also prevent liquid from entering the control room and damaging the control circuit.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-8This utility model provides a technical solution: a quick-installation, rapid-heating electronic water pump, including a control chamber assembly 1100, a pump head assembly 1200 installed inside the control chamber assembly 1100, a rear cover sealing ring 1103 fitted to the bottom of an inner and outer heating channel assembly 1300, a high-pressure connector body 1105 installed on the front top surface of the inner and outer heating channel assembly 1300, and a low-pressure connector body 1106 installed on the right side of the inner and outer heating channel assembly 1300. The rear cover body 1102, the high-pressure connector body 1105, and the low-pressure connector body 1106 are also present. The crimp connector body 1106 is fixedly connected to the inner and outer heating channel assembly 1300 by the first screw 1101. The control room assembly 1100 also includes a rear cover sealing ring 1103 installed at the connection between the rear cover body 1102 and the inner and outer heating channel assembly 1300. A high-pressure connector sealing ring 1104 is installed at the connection between the high-pressure connector body 1105 and the inner and outer heating channel assembly 1300. A low-pressure connector sealing ring 1107 is installed at the connection between the low-pressure connector body 1106 and the inner and outer heating channel assembly 1300. The right front side of the inner and outer heating channel assembly 1300... A waterproof vent cap 1108 is installed. The pump head assembly 1200 includes a volute body 1220 mounted on top of the inner and outer heating flow channel assembly 1300. An impeller rotor assembly 1203 is rotatably mounted inside the volute body 1220. A wear-resistant gasket assembly 1201 is installed at the connection between the top of the impeller rotor assembly 1203 and the volute body 1220. A volute sealing ring 1202 is installed at the connection between the bottom of the volute body 1220 and the inner and outer heating flow channel assembly 1300. An isolation sleeve body 1204 is wrapped around the outer ring of the impeller rotor assembly 1203. The top of the isolation sleeve body 1204 is flush with the volute body. The top of the inner ring of the body 1220 is fixedly connected, and the top outer ring of the isolation sleeve body 1204 is fitted with an isolation sleeve sealing ring 1205. The bottom end of the pump head assembly 1200 is fixedly installed with an inner and outer heating flow channel assembly 1300. The inner and outer heating flow channel assembly 1300 is installed with a motor stator assembly 1600. The motor stator assembly 1600 includes a motor housing 1601 fixedly installed on the top of the inner and outer heating flow channel assembly 1300. The motor housing 1601 is located in the inner ring of the heating cylinder screen printing assembly 1510. The stator assembly 1602 is installed inside the motor housing 1601.

[0040] The above structural design allows the volute body 1220 and the inner and outer heating channel assembly 1300 to be fixedly connected by bolts. When the rear cover body 1102 is connected to the inner and outer heating channel assembly 1300 by the first screw 1101, a rear cover sealing ring 1103 can be provided at the connection point, thereby improving the sealing performance of the rear cover body 1102. Similarly, when the high-pressure connector body 1105 is connected to the inner and outer heating channel assembly 1300 by the first screw 1101, a high-pressure connector sealing ring 1104 can be provided at the connection point, thereby ensuring high... The installation sealing of the press-fit plug body 1105 is ensured by the low-pressure plug body 1106 being connected to the inner and outer heating flow channel assembly 1300 via the first screw 1101. A low-pressure plug sealing ring 1107 is provided at the connection point to ensure the installation sealing of the low-pressure plug body 1106. The above-mentioned sealing installation can effectively prevent liquid from entering the interior and causing short circuits and damage, thus improving the sealing effect. The waterproof vent cap 1108 enables internal ventilation, avoids condensation and frost, and balances pressure to reduce the stress on the housing sealing strip.

[0041] The wear-resistant gasket assembly 1201 improves the wear resistance at the connection between the impeller rotor assembly 1203 and the volute body 1220. The volute sealing ring 1202 effectively seals the connection between the volute body 1220 and the internal and external heating flow channel assembly 1300. The fixed connection between the isolation sleeve body 1204 and the inner top wall of the volute body 1220 effectively isolates the internal impeller rotor assembly 1203. The isolation sleeve sealing ring 1205 on the outer top ring of the isolation sleeve body 1204 improves the sealing between the isolation sleeve body 1204 and the motor housing 1601, further enhancing the isolation effect. The stator assembly 1602 drives the impeller rotor assembly 1203 to rotate stably, achieving the driving operation of fluid flow.

[0042] A heating cylinder welding assembly 1500 is mounted on the top outer ring of the motor stator assembly 1600. The heating cylinder welding assembly 1500 includes a heating cylinder screen printing assembly 1510 fixedly mounted on the top of the inner and outer heating flow channel assembly 1300. A second screw 1520 is mounted on the front side of the heating cylinder screen printing assembly 1510. A waterproof cover 1540 is fitted around the outer ring of the second screw 1520. A nut 1560 is threaded onto the outer ring of the second screw 1520 located outside the waterproof cover 1540. An inner sealing ring 1530 is installed inside the waterproof cover 1540, and a sealing gasket 1550 is fixedly mounted on the bottom of the waterproof cover 1540. The heating cylinder screen printing assembly... A lead wire 1570 is installed on the bottom front side of 1510. The lead wire 1570 is connected to the sealing gasket 1550. The heating cylinder screen printing assembly 1510 includes a mounting lug 1516 fixedly installed on the top of the inner and outer heating flow channel assembly 1300. A heating substrate 1515 is fixedly connected to the inner ring of the mounting lug 1516. An insulating layer 1514 is connected to the inner ring of the heating substrate 1515. A heating resistance layer 1512 is installed on the inner ring of the insulating layer 1514. A conductor layer 1513 is installed on the bottom front side of the heating resistance layer 1512. The conductor layer 1513 is connected to the lead wire 1570. A protective layer 1511 is connected to the inner ring of the heating resistance layer 1512.

[0043] The above-described structure allows the sealing gasket 1550 to be fixedly connected to the bottom of the waterproof cover 1540. The waterproof cover 1540 can be fixedly installed on the bottom front side of the heating cylinder screen printing assembly 1510 by the second screw 1520 and the nut 1560. The waterproof cover 1540 uses the inner sealing ring 1530 to effectively seal and protect the lead wire 1570 at the bottom of the heating cylinder screen printing assembly 1510, preventing liquid from contacting the lead wire 1570 and causing a short circuit. The heating resistor layer 1512 avoids the installation position of the waterproof cover 1540, which can prevent local high temperature from causing the waterproof cover 1540, the inner sealing ring 1530 and the sealing gasket 1550 to age and fail after long-term operation.

[0044] Both the heating substrate 1515 and the mounting lug 1516 are made of corrosion-resistant metal and are welded together as a whole. This allows the heating substrate 1515 to be fixedly connected to the inner and outer heating flow channel assembly 1300 with the mounting lug 1516 and bolts, ensuring installation stability. Printing an insulating layer 1514 on the heating substrate 1515 can effectively improve the insulation effect. Printing a heating resistor layer 1512 on the insulating layer 1514, the heating resistor layers 1512 are connected by a conductor layer 1513 so that the lead wire 1570 can supply power to the heating resistor layer 1512 with the conductor layer 1513 when energized, so that the heating resistor layer 1512 can achieve heating. A protective layer 1511 is placed outside the heating resistor layer 1512 and the conductor layer 1513 to effectively improve the protection effect.

[0045] The top of the inner and outer heating flow channel assembly 1300 is connected to a spiral blade 1400. The gap between the motor housing 1601 and the heating cylinder screen printing assembly 1510 forms the inner heating flow channel, and the gap between the heating cylinder screen printing assembly 1510 and the volute body 1220 forms the outer heating flow channel. The inner heating flow channel has three sets of downward spiral blades 1400 with an inclination angle of 120 degrees. The outer heating flow channel has three sets of upward spiral blades 1400 with an inclination angle of 120 degrees.

[0046] The above-described structure design results in three sets of downward spiral blades 1400A, B, and C arranged in the inner heating channel, with the three sets of blades distributed at approximately 120 degrees, dividing the entire inner heating channel into three downward-extending heating channels A, B, and C; and three sets of upward spiral blades 1400D, E, and F arranged in the outer heating channel, with the three sets of blades distributed at approximately 120 degrees, dividing the entire outer heating channel into three upward-extending heating channels D, E, and F.

[0047] The bottom of the motor housing 1601 has three grooves that are blocked by the retaining edge, which connect the inner and outer heating channels. Specifically, the flow channel formed by AB and the flow channel formed by DF are connected at the groove, the flow channel formed by BC and the flow channel formed by DE are connected at the groove, and the flow channel formed by AC and the flow channel formed by EF are connected at the groove.

[0048] The pressurization chamber is formed by the volute body 1220 and the isolation sleeve body 1204. The volute body 1220 has one internal outlet, one outlet and two grooves. The internal outlet of the volute body 1220 is connected to any one of the flow channels formed by AB, BC or AC. Taking the connection between the internal outlet of the volute body 1220 and the flow channel formed by AB as an example: The internal outlet of the volute body 1220 is connected to the flow channel formed by AB. A water-blocking edge is set at the connection between the flow channel formed by AB and the flow channel formed by EF, so that the fluid can only flow out from the flow channel formed by AB. One groove connects the flow channel formed by AC and the flow channel formed by DE, the other groove connects the flow channel formed by BC and the flow channel formed by DF, and the outlet connects the flow channel formed by EF.

[0049] Liquid flows into the pressurization chamber from the inlet, passes through the aforementioned flow channel, and flows around the heating cylinder screen printing assembly 1510 in a spiral lifting and rotating manner for about two revolutions before flowing out through the outlet. This process fully heats the fluid. At the same time, the fluid temperature can be monitored and fed back in real time by the inlet and outlet temperature sensors on the motor housing 1601. The controller will adjust the temperature of the heater or the flow rate according to the PID algorithm to meet the actual working conditions.

[0050] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
