An evaporator assembly 1 according to an embodiment of the present invention is described below with reference to fig. 1 to 9.
As shown in fig. 1 to 9, an evaporator assembly 1 according to an embodiment of the first aspect of the present invention includes: an evaporator 11 and a drainage member 12.
Specifically, the evaporator 11 includes a fin body 114 and refrigerant tubes inserted into the fin body 114, the fin body 114 having opposite first and second ends in an insertion direction of the refrigerant tubes (refer to a left-right direction in fig. 1 to 3), portions of the refrigerant tubes adjacent to the first and second ends protruding outside the fin body 114, respectively, and being formed into bent tube segments 115. For example, in the example of fig. 1 to 3, the refrigerant tube is inserted into the fin body 114 in the left-right direction, the refrigerant tube forms the above-described bent tube segments 115 at both left and right side portions of the fin body 114, and the bent tube segments 115 are exposed to the outside of the fin body 114.
The flow director 12 is disposed on at least one of the first and second ends, the flow director 12 and the fin body 114 defining therebetween a receiving space adapted to receive the bend segment 115. Therefore, the drainage member 12 can be arranged at different positions of the evaporator 11 according to actual needs, so that the exposed bent pipe section 115 is accommodated in the accommodating space defined between the drainage member 12 and the fin body 114, and when the evaporator 11 is applied to equipment such as an air conditioner, condensed water generated by the bent pipe section 115 of the evaporator 11 can drop into the accommodating space defined between the drainage member 12 and the fin body 114 through the drainage effect of the drainage member 12 during refrigeration operation of the equipment such as the air conditioner, thereby preventing the problems of noise, water leakage, short circuit and the like caused by direct dropping of the condensed water onto other parts of the equipment such as the air conditioner, and improving the use reliability and safety of the equipment such as the air conditioner.
For example, the above-described flow guide 12 may be provided only at the first end of the fin body 114 to accommodate the bent pipe section 115 near the first end of the fin body 114 within the accommodation space defined by the flow guide 12 and the first end of the fin body 114; alternatively, the above-described flow guide 12 may be provided only at the second end of the fin body 114 to accommodate the bent pipe section 115 near the second end of the fin body 114 in the accommodation space defined by the flow guide 12 and the second end of the fin body 114; alternatively, the drainage member 12 may be disposed at the first end and the second end of the fin body 114, so as to accommodate the bent pipe sections 115 near the first end and the second end of the fin body 114 in the accommodating spaces defined by the drainage member 12 and the first end and the second end of the fin body 114, respectively.
The evaporator assembly 1 of the present invention will be described below by taking an example in which the evaporator 11 is used in an air conditioner.
It will be appreciated that a water tray is provided below the evaporator of the air conditioner, and typically, condensed water produced on the evaporator will flow down the evaporator into the water tray. However, since the above-mentioned bent pipe section portion of the evaporator is exposed to the outside of the fin body, the fin body is provided at both the first end and the second end with the above-mentioned plurality of bent pipe sections disposed at intervals. When the air conditioner works, condensed water generated on the pipe bending section is condensed to water drops with a certain diameter and then directly falls downwards, the water drops fall onto other parts, which are positioned nearby the evaporator, in the air conditioner, such as a motor cover of the motor, so that dripping noise can be generated, particularly, the condensed water generated on the pipe bending section with a higher evaporator position, due to the higher position, the water drops at the position are higher, so that splashing water is easy to generate when the water drops fall onto the motor cover and other parts, the water drops finally do not fall into a water receiving disc but are directly discharged from a shell gap of the air conditioner, the water leakage problem is caused, and even the splashed water drops are likely to splash onto the electrified part of the motor, so that potential safety hazards are caused by short circuits.
Therefore, in the invention, by arranging the drainage piece 12 on the evaporator 11, when the air conditioner performs refrigeration operation, condensed water generated by the bent pipe section 115 part of the evaporator 11 can drip into the accommodating space defined by the drainage piece 12 and the fin body 114 through the drainage effect of the drainage piece 12, the condensed water continues to flow downwards in the accommodating space through the drainage effect of the drainage piece 12, and finally the condensed water can be drained into the water receiving disc 4, so that the problems of noise, water leakage, short circuit and the like caused by the direct dripping of the condensed water onto the motor cover 3 can be prevented; or, the drainage member 12 may be disposed at the upper portion of the evaporator 11, so that the condensed water on the curved pipe section 115 with a higher position drops into the accommodating space defined by the drainage member 12 and the fin body 114 through the drainage function of the drainage member 12, and after the condensed water is drained through the drainage member 12, the condensed water drops onto the motor cover 3 from the lower side of the accommodating space, and then is guided into the water receiving tray 4 through the motor cover 3, thereby remarkably reducing the water drop level of the water drops, avoiding the water drops falling onto the motor cover 3 from forming splashed water, avoiding the problems of water leakage, short circuit and the like, and reducing the noise.
According to the evaporator assembly 1 of the embodiment of the invention, the drainage member 12 is arranged on the evaporator 11 so as to accommodate the bent pipe section 115 part of the refrigerant pipe extending out of the fin body 114 in the accommodating space defined by the drainage member 12 and the fin body 114, so that when the evaporator 11 is applied to equipment such as an air conditioner, condensed water generated by the bent pipe section 115 part of the evaporator 11 can drop into the accommodating space defined by the drainage member 12 and the fin body 114 through the drainage effect of the drainage member 12 during the refrigeration operation of the equipment such as the air conditioner, thereby preventing the problems of noise, water leakage, short circuit and the like caused by the direct drop of the condensed water onto other parts of the equipment such as the air conditioner, and improving the use reliability and safety of the equipment such as the air conditioner.
According to some alternative embodiments of the present invention, referring to fig. 3-8, the drainage member 12 comprises: the drainage member body 121 and the buckling part 122 define the accommodating space between the drainage member body 121 and the fin body 114, the buckling part 122 is arranged on the side wall of the drainage member body 121 facing the fin body 114, and the buckling part 122 is suitable for being matched with the bent pipe section 115 to connect the drainage member 12 to the evaporator 11. Thus, the drainage member 12 is engaged with the bent pipe section 115 of the evaporator 11 by the engaging portion 122, so that the drainage member 12 can be easily mounted and fixed on the evaporator 11.
The shape of the flow guide body 121 may be set according to the actual shape of the evaporator 11, or may be set according to the shape of the portion of the flow guide 12 where the evaporator 11 is required. For example, in the example of fig. 1 to 3, the portion of the flow guide 12 to be provided in the evaporator 11 is shaped like a V with a large opening angle, and the flow guide body 121 is also formed like a V matching therewith.
It will be appreciated that the evaporator 11 has a plurality of the above-described bend segments 115, and that the snap-fit portions 122 of the flow director 12 can cooperate with a portion of the bend segments 115 to secure the flow director 12 to the evaporator 11. For example, only one fastening portion 122 may be provided on the flow guide 12, and the flow guide 12 may be mounted and fixed on the evaporator 11 by the fastening portion 122 cooperating with one of the bent pipe sections 115; alternatively, a plurality of fastening portions 122 may be disposed on the drainage member 12, and the plurality of fastening portions 122 cooperate with a corresponding number of bent pipe segments 115 to fix the drainage member 12 to the evaporator 11.
Referring to fig. 1 to 9, the buckling part 122 is plural and the plurality of buckling parts 122 are arranged at intervals along the extending direction of the drainage body 121. Thus, a different number of the catching parts 122 can be provided according to the size of the drainage member 12, so that the drainage member 12 can be more firmly installed and fixed on the evaporator 11. For example, the number of the fastening parts 122 may be three, and the three fastening parts 122 are disposed adjacent to the upper, middle and lower ends of the flow guide body 121, respectively, so that the flow guide 12 is uniformly and stably coupled to the evaporator 11.
Further, referring to fig. 4, 6 and 8, the fastening portion 122 includes: the connecting plate 1221 and the clamping plate 1222, the connecting plate 1221 is arranged on the drainage piece body 121 and extends towards the fin body 114, the clamping plate 1222 is arranged at the free end of the connecting plate 1221, and the clamping plate 1222 and the connecting plate 1221 can be mutually perpendicular. When the bent pipe section 115 is fitted with the catching portion 122, the bent pipe section 115 is inserted into the space between the catching plate 1222 and the connecting plate 1221, and the side wall of the bent pipe section 115 facing the fin body 114 and the side wall of the catching plate 1222 away from the fin body 114 are brought into abutment with each other. Therefore, the drainage member 12 can be conveniently clamped on the evaporator 11 by the mutual abutting and clamping of the clamping part 122 and the bent pipe section 115, and the structure of the clamping part 122 is simple.
Alternatively, referring to fig. 4, 6 and 8, the side wall of the snap plate 1222 remote from the fin body 114 is formed into an arcuate surface that mates with the bend tube segment 115. Thus, when the bend pipe section 115 is engaged with the fastening portion 122, the bend pipe section 115 and the arcuate surface are engaged with each other, so that the fastening portion 122 is engaged with the bend pipe section 115 more firmly.
According to some alternative embodiments of the present invention, referring to fig. 6 and 8, the drainage member 12 further comprises: the limiting part 123 is arranged on the drainage piece body 121, the limiting part 123 is arranged adjacent to the buckling part 122 and is spaced apart from the buckling part 122, and when the buckling part 122 is matched with the bent pipe section 115, the bent pipe section 115 is accommodated between the limiting part 123 and the buckling part 122. Therefore, through the combined action of the limiting part 123 and the buckling part 122, the bent pipe section 115 can be better limited, so that the connection and the matching between the drainage piece 12 and the evaporator 11 are more stable and firm.
According to some alternative embodiments of the present invention, referring to fig. 1-6, the drainage member body 121 is provided with a relief opening 125 penetrating the drainage member body 121 in a thickness direction, and the fastening portion 122 is disposed adjacent to a peripheral edge of the relief opening 125, and when the fastening portion 122 is mated with the bend pipe section 115, the bend pipe section 115 is opposite to the relief opening 125. Therefore, more installation space can be avoided through the above-mentioned avoiding opening 125, and the problem that the installation difficulty is caused by interference or insufficient installation space with the drainage piece body 121 in the process of clamping and matching the bent pipe section 115 and the clamping part 122 when the drainage piece 12 is installed on the evaporator 11 is avoided, so that the installation and fixation of the drainage piece 12 are more convenient, quicker and easy to operate.
According to some alternative embodiments of the present invention, referring to fig. 1 to 3 and 5, the drain body 121 is formed in a plate shape, the opposite sides of the drain body 121 (referring to the front and rear sides of the drain body 121 in fig. 1 to 3 and 5) are formed with flange portions 124 extending toward the fin body 114, the flange portions 124 are abutted against the fin body 114, and the receiving space is defined between the drain body 121, the flange portions 124 and the fin body 114. Therefore, by the flange parts 124 formed on the two sides of the drainage member body 121, and the flange parts 124 are abutted against the fin body 114, the bent pipe section 115 of the refrigerant pipe can be better wrapped, the condensed water generated on the bent pipe section 115 flows along the containing space, the splash is further reduced, and meanwhile, the matching area of the drainage member 12 and the evaporator 11 can be increased, so that the drainage member 12 is more firmly connected to the evaporator 11.
