Further, first header 11 and second header 12 close to 13 side of the flat tube surface according to Sequence offers the first groove 100 to match with the upper side plate 14, the flat tube 13 and 15 both ends of lower side plate, and described One groove 100 is connected to corresponding first header 11 and second header 12 respectively.In practical applications, first will It is recessed that the upper side plate 14, the flat tube 13 and described 15 one end of lower side plate correspond to first be arranged on first header 11 In slot 100, then the flat tube 13 and 15 other end of lower side plate are corresponded to the first groove being arranged on the second header 12 In 100, will finally be welded at engaging, to improve the upper side plate 14, the flat tube 13 and the lower side plate 15 with First header 11 and the overall stability of second header 12 connection.
The upper side plate 14 is upward including one the oneth I shapes fixed plate 141 and set on 141 both sides of the first I shapes fixed plate The first extension plate 142 extended, the length of first extension plate 142 are less than the length of the first I shapes plate 141, and described the One extension plate 142 is used to increase the integral strength of the first I shapes fixed plate 141.
The mounting bracket 20 is two, and two mounting brackets 20 are set to the first I shapes fixed plate 141 and institute The first extension plate 142 is stated to enclose in the receiving space set.Wherein each mounting bracket 20 respectively include a mounting plate 21 and The mounting post 22 being detachably connected with the mounting plate 21.The mounting plate 21 is continuously bent by a metallic plate, the peace Loading board 21 is substantially L-shaped.The bottom end of 21 first end of the mounting plate is fixedly connected with the first I fixed plates 141, the peace The opposite sides of 21 first end of loading board leans with first extension plate 142 respectively, wherein 21 first end of the mounting plate The bottom in portion is further opened with one second groove 211, second groove 211 for avoid 21 first end of the mounting plate due to It expands with heat and contract with cold and first extension plate 142 to lean is made crimp occur while reduce the entirety of the mounting plate 21 Quality.The mounting plate 21 is equipped with a mounting hole 212 close to the surface of 21 the second end side of the mounting plate.The installation Column 22 is hollow structure, and the mounting post 22 includes the first fixed part 221 and is fixedly connected with first fixed part 221 Second fixed part 222, second fixed part 222 are detachably connected with the mounting hole 212, second fixed part 222 Sectional dimension is less than the described first sectional dimension for fixing 221.
The lower side plate 15 is downward including one the 2nd I shapes fixed plate 151 and set on 151 both sides of the 2nd I shapes fixed plate The second extension plate 152 extended, the length of second extension plate 152 are less than the length of the 2nd I shapes fixed plate 151, institute State integral strength of second extension plate 152 for increasing the 2nd I shapes plate 151.
The mounting base 30 is two, and two mounting bases 30 are set to the 2nd I shapes fixed plate 151 and described the In the receiving space that two extension plates 152 are surrounded, each mounting base 30 is including a mounting blocks 31 and is sheathed on the installation The installation set 32 of 31 periphery of block.For the mounting blocks 31 for fastening with external equipment, the mounting blocks 31 are a rectangle die casting Part, the mounting blocks 31 be fixedly arranged on the top of the 2nd I shapes fixed plate 151 and both sides respectively with one second extension plate, 152 phase Against.The material of the installation set 32 is rubber, due to collision when directly engaging with external equipment to avoid the mounting blocks 31 And generate noise and damage.
This should be noted that first header, 11 side far from the flat tube 13 is equipped with a drying bottle again 16, the drying bottle 16 is for absorbing moisture and impurity that may be present in refrigerant.The drying bottle 16 is close to described flat Connector 161 described in 3 connectors 161 is arranged on the surface of 13 side of pipe in I-shaped, the connector 161 be used for First header 11 is clamped.In addition, being equipped with a corrugated radiating fin 131, institute between the two neighboring flat tube 13 State heat dissipation performance of the radiating fin 131 for improving condenser pipe described in the condenser.
When needing using the condenser 30, first diversion pipe 111 and second diversion pipe 121 are distinguished It is connect with first header 11 and second header 12, by several flat tubes 13, the upper side plate 14 and described Lower side plate 15 is correspondingly connected with the first groove 100 on first header, 11 and second header 12 respectively, and is being connected Place is welded and fixed, to improve the stability of the condenser entirety, the institute being located between the two neighboring flat tube 13 The heat dissipation performance that radiating fin 131 has increased the flat tube 13 is stated, fixes connect with the upper side plate 14 and the lower side plate 15 respectively The mounting bracket 20 and the mounting base 30 connect is convenient for the condenser and is directly fixedly connected with body of a motor car, and institute is worked as When stating condenser working, cooling flow is entered after first header 11 by first diversion pipe 111 along the flat tube 13 enter second headers 12, and by described the on second header 12 after being recycled according to preset path Two diversion pipes 121 are discharged.Since the condensation vessel volume is small and heat dissipation performance is good, practical application request is met.
Referring to Fig. 7, the structural schematic diagram for the condenser showing in the utility model second embodiment, in the present embodiment Condenser and first embodiment in condenser it is more or less the same, the difference is that condenser in the present embodiment is real first On the basis of applying example, the surface of the radiating fin 131 is equipped with several heat dissipation convex blocks 132, the opposite of convex block 132 of radiating Both sides offer heat dissipation seam (not marked in figure).The heat dissipation convex block 132 stitches (not marked in figure) mating reaction with the heat dissipation, To improve the heat dissipation performance of the radiating fin, practical application request is met.
Above example only expresses the several embodiments of the utility model, the description thereof is more specific and detailed, but simultaneously Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that for the ordinary skill of this field For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
