Description

Technical Field

[0001] The utility model relates to the field of vehicle air conditioners, in particular to a side-by-side evaporator. Background Art

[0002] An evaporator is a device used to turn liquid into gas. Its main principle is that liquid turns into gas while absorbing heat. Inside the evaporator, after the input of fluid, due to the high temperature of the outside world, the low-temperature liquid inside absorbs heat and turns into steam. Such steam can be freely transferred in the atmosphere, thus completing the entire evaporation process.

[0003] The traditional evaporator is composed of two front and rear heat dissipation modules, so the length of each heat dissipation module is relatively long. When the liquid refrigerant enters the heat dissipation fins from the inlet, the flow length is relatively long, resulting in inconsistent flow of each fin, which in turn leads to different heat dissipation effects; at the same time, the integrated design is not conducive to maintenance and replacement, which increases the cost for users. Utility Model Content

[0004] The utility model aims to provide a side-by-side evaporator with good refrigeration effect and independent division.

[0005] The purpose of the utility model is achieved as follows: a side-by-side evaporator comprises a right heat dissipation module and a left heat dissipation module, the right heat dissipation module is composed of a first heat dissipation module and a second heat dissipation module arranged in parallel; the left heat dissipation module is composed of a third heat dissipation module and a fourth heat dissipation module arranged in parallel; the first heat dissipation module and the second heat dissipation module are provided with a first upper collecting tube on the top and a first lower collecting tube on the bottom; the third heat dissipation module and the fourth heat dissipation module are provided with a second upper collecting tube on the top and a second lower collecting tube on the bottom; the first upper collecting tube, the first lower collecting tube and the second lower collecting tube are all provided with partitions along the long side direction to divide the interior into two front and rear collecting cavities; the end of the first upper collecting tube is provided with two groups of interfaces respectively connected with the two collecting cavities inside; the two groups of interfaces are connected with a liquid distributor; a connecting pipe is provided between the first lower collecting tube and the second lower collecting tube; an air outlet is provided at one end of the outer side of the second upper collecting tube.

[0006] Preferably, protective side panels are provided on both sides of the first heat dissipation module, the second heat dissipation module, the third heat dissipation module and the fourth heat dissipation module, and connecting bridges are respectively provided at the upper and lower ends of the inner protective side panels opposite to the first heat dissipation module and the third heat dissipation module, and the second heat dissipation module and the fourth heat dissipation module, and the connecting bridges are connected to the protective side panels by bolts.

[0007] Preferably, a heat insulation plate is provided between the upper and lower groups of connecting bridges.

[0008] Preferably, fixing plates are provided on both sides of the connection bridge, a slot is provided between the fixing plates on both sides, the slot is integrally connected to the connection bridge, and the heat insulation plate is inserted into the slot and fixed by bolts.

[0009] Preferably, there are two groups of connecting pipes, which respectively connect the collecting cavities corresponding to the first lower collecting pipe and the second lower collecting pipe.

[0010] Compared with the prior art, the utility model is beneficial in that:

[0011] 1. The evaporator is divided into two groups of cooling modules, the left and right. The right cooling module turns the liquid refrigerant into mist, and the mist refrigerant turns into gas under low pressure. The gas is driven to the left cooling module by the compressor to achieve secondary heat absorption during the rising process of the gas. The left and right modules operate independently and are highly efficient. The middle is separated by a heat insulation board to ensure the balance of hot air between the left and right modules, preventing one side from absorbing too much hot air, resulting in insufficient temperature of the surrounding environment of the other side, and unable to provide heat that can be absorbed by the evaporator, so as to improve the refrigeration efficiency.

[0012] 2. The liquid refrigerant is evenly distributed to the first heat dissipation module and the second heat dissipation module of the right heat dissipation module through a distributor, and the vaporization effect can be achieved at the same time. The lengths of the first heat dissipation module and the second heat dissipation module are respectively shorter than the length of the traditional evaporator. Therefore, the flow rate of the liquid refrigerant flowing into the fins in each heat dissipation module is more balanced, which is conducive to improving the vaporization heat absorption effect.

In addition, the terms "first", "second", "third" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. Terms such as "horizontal", "vertical", and "overhanging" do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-5As shown, a side-by-side evaporator comprises a right heat dissipation module 1 and a left heat dissipation module 2, wherein the right heat dissipation module 1 is composed of a first heat dissipation module 3 and a second heat dissipation module 4 arranged in parallel; the left heat dissipation module 2 is composed of a third heat dissipation module 5 and a fourth heat dissipation module 6 arranged in parallel; the first heat dissipation module 3 and the second heat dissipation module 4 are provided with a first upper header 7 on the top and a first lower header 8 on the bottom; the third heat dissipation module 5 and the fourth heat dissipation module 6 are provided with a second upper header 9 on the top and a second lower header 10 on the bottom; the first upper header 7, the first lower header 8 and the second lower header 10 are provided with a partition 11 along the long side direction to divide the interior into two front and rear header cavities; the end of the first upper header 7 is provided with two groups of interfaces respectively connected to the two internal header cavities; the two groups of interfaces are connected to a liquid distributor 12, and the liquid distributor has a total inlet on the outside; a connecting pipe 13 is provided between the first lower header 7 and the second lower header 8; an air outlet 14 is provided at one end of the outer side of the second upper header 9.

[0023] like Figure 1-2 As shown, protective side panels 15 are provided on both sides of the first heat dissipation module 3, the second heat dissipation module 4, the third heat dissipation module 5, and the fourth heat dissipation module 6. Connecting bridges 16 are provided at the upper and lower ends of the inner protective side panels 15 opposite to the first heat dissipation module 3 and the third heat dissipation module 5, and the second heat dissipation module 4 and the fourth heat dissipation module 6, respectively. The connecting bridges are connected to the protective side panels by bolts. The protective side panels can protect the evaporator body and serve as a mounting base for the connecting bridges. Further installation of the connecting bridges can provide higher stability.

[0024] like Figure 2 As shown, a heat insulation board 17 is provided between the upper and lower groups of connecting bridges 16, and the heat insulation board is detachable, so the installation is convenient and quick.

[0025] like Figure 3 As shown, fixing plates 1601 are provided on both sides of the connecting bridge 16, and a slot 1602 is provided between the fixing plates 1601 on both sides. The slot is integrally connected to the connecting bridge. The heat insulation plate 17 is inserted into the slot 1602 and fixed by bolts. The heat insulation is mainly used to divide a space into two areas to ensure the ambient temperature in each space to improve the vaporization heat absorption effect.

[0026] like Figure 1-2 As shown, there are two groups of connecting pipes 13, which respectively connect the collecting cavities opposite to the first lower collecting pipe 7 and the second lower collecting pipe 8. The first lower collecting pipe and the second lower collecting pipe are respectively provided with two collecting cavities. The collecting cavities transmit the vaporized gas to the left heat dissipation module through the connecting pipes to realize secondary heat absorption.

[0027] The working principle of the present invention is explained as follows: the length of the first heat dissipation module and the second heat dissipation module is equivalent to the length of the front heat dissipation module of the traditional structure; the length of the third heat dissipation module and the fourth heat dissipation module is equivalent to the length of the rear heat dissipation module of the traditional structure. The length of each heat dissipation module in the present application is relatively small, and the liquid refrigerant does not need to go through a long journey to be distributed to each heat dissipation fin. Furthermore, the flow rate of the heat dissipation fins in each heat dissipation module is more uniform and the effect is better. At the same time, the left and right modules can be disassembled separately and replaced, which is lower in cost and is conducive to market promotion.
