Description
Technical Field
[0001] This utility model belongs to the field of vehicle air conditioning technology, and in particular relates to a dual-system air conditioning assembly. Background Technology
[0002] Currently, the air conditioners used in long vehicles such as buses and coaches are conventional vehicle air conditioners. Due to the long length and large space of the vehicles, they cannot quickly achieve a comfortable temperature inside the vehicle in the hot summer or the cold winter. If a comfortable temperature is to be achieved quickly, the vehicle air conditioner needs to be overloaded, which seriously affects the safety and service life of the vehicle. Utility Model Content
[0003] This utility model provides a dual-system air conditioning assembly to quickly achieve a comfortable temperature inside the vehicle and solve the problem of overload operation affecting safety and service life.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-system air conditioning assembly, including an outer shell with vent holes, an evaporator box inside the outer shell, a partition inside the evaporator box, fans mirror-installed in the evaporator boxes on both sides of the partition, a cooling core, a heating core and an air outlet chamber sequentially arranged in the evaporator boxes downstream of the two fans, and a condenser and a compressor on the outer shell outside the evaporator box;
[0005] The evaporator housing corresponding to the cooling core and the heating core is provided with a centralized condensate drainage structure;
[0006] It also includes an air inlet / outlet panel connected to the outer casing. The air inlet / outlet panel has multiple air inlets and multiple air outlets on both sides of the air inlets. The air inlets are also corresponding to the installation positions of the two fans. The air outlets are corresponding to the air outlet chambers, and an air outlet pipe is provided between the air outlets and the air outlet chambers.
[0007] As an improvement, the centralized condensate discharge structure includes two base plates disposed at the bottom of the evaporator housing, each base plate corresponding to a cooling core and a heating core;
[0008] A water collection trough is formed by bending on the bottom plate. A first baffle plate is formed by bending on the bottom plate on one side of the water collection trough toward the fan. A second baffle plate is formed by bending on the bottom plate on the other side of the water collection trough toward the air outlet chamber.
[0009] Each of the water collection tanks is equipped with a drain pipe at both ends, and the two drain pipes at each end are connected by a T-junction.
[0010] As a further improvement, the water collection tank is provided with a hollow pad, the bottom of the cooling core abuts against the pad, and water holes are provided around the perimeter of the pad;
[0011] The medium flow pipe on the cooling core is arranged vertically.
[0012] As a further improvement, both the first and second water-blocking plates are formed by multiple bending processes.
[0013] The second baffle plate extends at an angle away from the heating core, and the second baffle plate is also provided with a baffle plate that folds back towards the heating core.
[0014] As an improvement, a positioning plate is provided on the inner wall of the evaporator box located at both ends of each of the refrigeration cores, and the positioning plate is provided with a positioning groove for positioning the refrigeration cores;
[0015] The heating core is provided with an installation plate, and the inner wall of the evaporator box at both ends of each heating core is provided with an insertion plate. The insertion plate at the corresponding position of the installation plate is provided with an insertion slot for positioning the installation plate.
[0016] As a further improvement, the bottom of the mounting plate is provided with a bent connecting plate, the connecting plate abutting against the bottom plate, and the length of the connecting plate is less than the distance between the two insert plates. The mounting plate located at both ends of the connecting plate is provided with a return groove.
[0017] As a further improvement, a dustproof net is provided on the air inlet / outlet panel at the position corresponding to the air inlet hole.
[0018] As an improvement, a hanger is provided inside the housing, and the hanger is provided with lugs extending to the outside of the housing.
[0019] As an improvement, the condenser is located downstream of the outlet chamber and arranged in sequence.
[0020] As an improvement, the compressors are distributed on both sides of the evaporator housing.
[0021] After adopting the above technical solution, the effect of this utility model is:
[0022] The dual-system air conditioning assembly includes an outer casing with vents, an evaporator housing inside the casing, a partition inside the evaporator housing, and fans mirror-mounted inside the evaporator housings on both sides of the partition. Downstream of the two fans, each evaporator housing sequentially contains a cooling core, a heating core, and an air outlet chamber. A condenser and a compressor are mounted on the outer casing outside the evaporator housings. A centralized condensate drainage structure is provided on the evaporator housings corresponding to the cooling and heating cores. It also includes an air inlet / outlet panel connected to the outer casing, with multiple air inlets on the panel. The air inlet and outlet panels on both sides of the air inlet are equipped with multiple air outlets. The air inlet is also set to correspond to the installation position of the two fans. The air outlet is set to correspond to the air outlet chamber, and an air outlet pipe is provided between the air outlet and the air outlet chamber. When this dual-system air conditioning assembly is in use, it works through two sets of air conditioning systems on both sides of the partition (each set of systems includes a fan, a cooling core, a heating core, an air outlet chamber, a condenser, and a compressor). If a large amount of cooling or heating is required, both sets of air conditioning systems work at the same time. Otherwise, only one set of air conditioning system needs to be selected.
[0023] In summary, the adoption of this dual-system air conditioning assembly significantly increases the cooling or heating capacity, achieving a rapid attainment of a comfortable in-vehicle temperature. Furthermore, the dual systems can be used simultaneously or individually, ensuring high reliability and effectively solving the problem of overload operation affecting safety and service life.
[0024] The centralized condensate drainage structure includes two base plates located at the bottom of the evaporator housing, each corresponding to a cooling core and a heating core. A water collection trough is formed by bending on each base plate. A first baffle plate is formed on one side of the water collection trough, bent towards the fan, and a second baffle plate is formed on the other side of the water collection trough, bent towards the air outlet chamber. Each water collection trough has drain pipes at both ends, connected by a T-junction. This allows the condensate generated by the cooling core during operation to be collected centrally in the water collection trough and then drained to other locations via the drain pipes and T-junction. Since the cooled or heated gas is blown by the fan, there is a possibility that condensate may be carried away simultaneously. Therefore, the first and second baffle plates prevent condensate from being blown into the air outlet chamber and the vehicle interior.
[0025] Because the water collection tank has a hollow pad, the bottom of the refrigeration core rests against the pad, and water holes are provided around the perimeter of the pad; the medium flow pipe on the refrigeration core is set vertically, so that the condensate can flow downward naturally to the water collection tank through the vertical medium flow pipe, which helps to reduce the probability of the condensate being blown away at the same time; the water holes on the pad make it easy for the flowing water to enter the water collection tank for discharge. The structure is simple and effectively improves the drainage effect.
[0026] Because both the first and second baffles are formed by multiple bending processes, and the second baffle extends at an angle away from the heating core, and also has a baffle that folds back towards the heating core, the multiple bending processes not only improve the structural strength of the base plate, but also increase the coverage area of the base plate for receiving condensate, thus further preventing condensate from being blown into the air outlet chamber. The angled extension of the second baffle facilitates the sliding of condensate blocked by it, and in conjunction with the baffle, it acts as a buffer to block or buffer cold or hot air, allowing cold or hot air to enter the vehicle evenly and gently, thus improving comfort.
[0027] Because each evaporator casing at both ends of the refrigeration core has a positioning plate with a positioning groove for positioning the refrigeration core; and the heating core has an installation plate, and each evaporator casing at both ends of the heating core has an insertion plate with an insertion groove for positioning the installation plate, the refrigeration core can be inserted and removed by insertion through the positioning plate with the positioning groove, and the installation plate on the heating core can be inserted and removed by insertion through the insertion plate with the insertion groove. The structure is simple, and the disassembly and assembly are convenient and efficient.
[0028] Because the bottom of the mounting plate is provided with a bent connecting plate, the connecting plate abuts against the bottom plate and the length of the connecting plate is less than the distance between the two insert plates. The mounting plates at both ends of the connecting plate are provided with return grooves, thereby improving the stability of the mounting plate and the heating core on it by the abutting between the connecting plate and the bottom plate. At the same time, the short length of the connecting plate will not affect the insertion fit between the mounting plate and the insert plate. The return groove facilitates the flow of condensate blocked by the second baffle plate towards the water collection tank.
[0029] Because the air inlet and outlet panels corresponding to the air inlet are equipped with dust filters, the gas entering the evaporator housing through the air inlet is filtered by the dust filters.
[0030] Because a hanger is located inside the housing, and the hanger has lugs that extend to the outside of the housing, the installation and removal of the dual-system air conditioning assembly is facilitated by the cooperation of the lugs and the hanger (because the dual-system air conditioning assembly is heavy), saving time and effort.
[0031] Because the condensers are located downstream of the outlet chamber and arranged sequentially, the distribution is reasonable and compact, and the space occupied is small.
[0032] Because the compressors are located on both sides of the evaporator housing, they are symmetrically and rationally distributed, resulting in more even force distribution. Attached Figure Description
