[0016] As an improvement, mounting bases are provided at both ends of the housing; the blower is a brushless blower.
[0017] After adopting the above technical solution, the effect of this utility model is:
[0018] The evaporator assembly includes a housing with an installation chamber inside. One side of the housing has multiple air inlets communicating with the installation chamber, and the other side has a blower. The blower's inlet connects to the installation chamber, and its outlet connects to an air hood with an outlet pipe. Positioning seats are located on both sides of the housing within the installation chamber. A cooling core is inserted into one side of the housing, and a heating core is inserted into the other. The housing also has a drainage structure. The evaporator assembly is quickly assembled by inserting and removing the cooling and heating cores. During operation, the blower generates suction, drawing air into the housing through the air inlets. Simultaneously, the cold or hot air generated by the cooling or heating cores is drawn into the blower and then sent into the air hood. From there, the cold or hot air is delivered into the driver's cab via a branch pipe. Condensate generated during the cooling process is centrally discharged through the drainage structure.
[0019] In summary, the use of this evaporator assembly simplifies the assembly and disassembly process by inserting the cooling and heating cores. The simple structure and high ease of assembly and disassembly help improve assembly and disassembly efficiency. Moreover, the use of a blower to connect and transition between the housing and the air outlet hood improves the structural compactness, resulting in a small size and low space occupancy.
[0020] Since the heating core is equipped with insertion positioning plates on both sides, the insertion positioning plates are inserted into the positioning slots, and the positioning slots are opened on the positioning seats. Thus, through the cooperation of the insertion positioning plates and the positioning slots, not only is the quick disassembly and assembly of the heating core not affected, but the positioning is also reliable and accurate. At the same time, it plays a protective role, avoiding damage caused by collision with the box and positioning seats when shaking.
[0021] Because the housing has a clearance groove, the water inlet and outlet pipes of the heating core pass through the clearance groove and extend to the outside of the housing. A connecting plate is provided between the water inlet and outlet pipes. The housing has a sealing structure at the position corresponding to the clearance groove, which facilitates the arrangement of the water inlet and outlet pipes through the clearance groove. The connecting plate increases the structural strength and also plays a role in preventing torsion. The sealing structure seals the clearance groove to prevent a large amount of cold or hot air from leaking out, so as to ensure the cooling or heating effect in the cab.
[0022] The sealing structure includes a sealing plate installed on the outer wall of the housing. The sealing plate passes through the inlet and outlet pipes and covers the clearance groove. The sealing plate is bent into a folded plate, which is fixedly connected to the connecting plate. Thus, the clearance groove is sealed by the sealing plate. The connection between the folded plate and the connecting plate ensures the positional stability of the inlet and outlet pipes, preventing shaking during vehicle movement and affecting the reliability of the connection between the inlet and outlet pipes and the heating core.
[0023] The drainage structure includes a water collection trough located at the bottom of the housing and protruding from it. The water collection trough has an inclined plate corresponding to the refrigeration core, and a drain pipe is installed on the inclined plate. The drain pipe is located at the lower part of the water collection trough, so that the condensate is collected in a concentrated manner through the water collection trough, and the condensate is guided and discharged towards the drain pipe through the inclined plate. The structure is simple and has a good drainage effect.
[0024] The refrigeration core includes an upper water chamber and a lower water chamber, with multiple vertically arranged connecting pipes between them. The outer wall of the lower water chamber has multiple abutting protrusions that abut against the bottom of the housing. Thus, during the operation of the refrigeration core, the condensate generated flows downward naturally through the vertically arranged connecting pipes and enters the water collection tank. The abutting protrusions create a connection between the refrigeration core and the bottom of the housing, allowing the flowing condensate to smoothly enter the water collection tank, which helps to improve the condensate drainage rate.
[0025] Because there are multiple air outlet ducts distributed at the ends and sides of the air outlet hood, it helps to quickly and evenly distribute cold or hot air in the cab.
[0026] Because the air outlet duct and the blower's air outlet are staggered, and the air outlet hood corresponding to the blower's air outlet is equipped with an inclined guide plate, the staggered arrangement avoids the large impact force of the cold or hot air coming out of the blower, which could cause discomfort in the cab. The inclined guide plate buffers the cold or hot air coming out of the blower, so that the cold or hot air can enter the cab evenly through the air outlet duct.
[0027] The housing with the air inlet is provided with first heat insulation cotton; the inner wall of the housing and the positioning seat are provided with second heat insulation cotton between them and the cooling core; and the heating core is provided with insulation cotton below it. Thus, the first heat insulation cotton, the second heat insulation cotton and the insulation cotton can play the roles of heat insulation, heat preservation, shock absorption and sealing.
[0028] Since there are mounting bases at both ends of the housing, the evaporator assembly can be directly installed through the mounting bases without the need for other auxiliary installation structures; since the blower is a brushless blower, there is no mechanical contact wear, resulting in more stable operation and a longer service life.
