Fig. 1 to 6 exemplarily show schematic structural views of an evaporator assembly and an evaporator stand thereof in the present application.

Wherein fig. 1 and 2 exemplarily show the structure of the evaporator assembly of the present application.

Referring to fig. 1 and 2, in the present application, an evaporator assembly 100, which is a constituent part of a refrigerating apparatus such as an air conditioner, includes an evaporator 20 and an evaporator stand 10. The evaporator 20 is provided on the evaporator stand 10 to be supported by the evaporator stand 10. And with continued reference to fig. 1 and 2, in some embodiments, the evaporator assembly 100 further includes a drip tray 30. The water pan 30 is used for receiving condensed water generated by the evaporator 20. Typically, the drip tray 30 is disposed below the evaporator 20 and in contact with the evaporator stand 10.

Fig. 3 to 6 further illustrate the structure of the evaporator stand in the present application.

Referring to fig. 3 to 6, and referring to fig. 1 and 2, in the present application, an evaporator stand 10 includes a base 1 and a stopper 2. The limiting part 2 is arranged on the base body 1 and comprises a limiting cavity 21, a first buckle 22 and a second buckle 23. The limiting cavity 21 is used for passing through the heat exchange tube 201 of the evaporator 20. The first buckle 22 and the second buckle 23 are arranged on the side walls of different limiting cavities 21 of the limiting part 2 and are used for being clamped with the heat exchange tubes 201 in the limiting cavities 21. The side wall of the limiting cavity 21 where the first buckle 22 is located is provided with two first notches 24, and the two first notches 24 are located at two sides of the first buckle 22 along the first direction. The side wall of the limiting cavity 21 where the second buckle 23 is located is provided with a second notch 25, and the second notch 25 is located on one side of the second buckle 23 along the first direction. The first direction is perpendicular to the depth direction of the spacing cavity 21.

In the above-mentioned scheme, because both sides along the first direction of the first buckle 22 are provided with the notch (i.e. the first notch 24), and only one side along the first direction of the second buckle 23 is provided with the notch (i.e. the second notch 25), therefore, the first buckle 22 may have a hardness smaller than that of the second buckle 23, that is, the first buckle 22 has a smaller hardness, a larger elasticity, and a larger hardness and a smaller elasticity of the second buckle 23, and the first buckle 22 has a smaller hardness and a larger elasticity than the second buckle 23, in this case, the evaporator bracket 10 does not only have the buckles with the same hardness, but also has the buckles with different hardness, and the evaporator bracket 10 can not only utilize the softer first buckle 22 to reduce the assembly difficulty, reduce the damage to the heat exchange tube 201, but also can utilize the harder second buckle 23 to realize the firmer combination with the heat exchange tube 201, and reliably limit, so the evaporator bracket 10 can have the convenience of assembly and the firm limit, which is favorable for improving the assembly efficiency of the evaporator assembly 100 and the refrigeration equipment, but also improving the reliability of the evaporator assembly 100 and the refrigeration equipment.

Wherein the first clasp 22 may be referred to as a weak clasp; the second clasp 23 may be referred to as a strong clasp.

In order to maximize the strength of the first clasp 22 while providing the first clasp 22 with less rigidity, referring to fig. 3, in some embodiments the first notch 24 is configured not to extend to the bottom end of the side wall of the spacing cavity 21 where the first clasp 22 is located. Under such circumstances, the first notch 24 may be made by removing material, but not going to the bottom (or drawing material, but not drawing bottom), and a distance exists between the first notch 24 and the bottom end of the side wall of the limiting cavity 21 where the first buckle 22 is located, and a portion of the side wall of the limiting cavity 21 is still left below the first notch 24, so that the first buckle 22 is prevented from being too soft, so that the first buckle 22 may have smaller hardness, but not too small hardness, but has a certain strength, so that on the basis of facilitating the assembly of the first buckle 22 and the heat exchange tube 201, the strength of the first buckle 22 is improved as much as possible, and the fastening firmness of the first buckle 22 and the heat exchange tube 201 is improved, so that the evaporator bracket 10 can better compromise the assembly convenience and the limiting firmness.

In addition, in order to maximize the flexibility of the second clasp 23 while providing greater rigidity to the second clasp 23, referring to FIG. 3, in some embodiments the second notch 25 is configured to extend to the bottom end of the side wall of the spacing cavity 21 where the second clasp 23 is located. Under such circumstances, the second notch 25 may be formed by removing material and going to the bottom (or taking out material and taking out bottom, taking out empty), and there is no longer a distance between the second notch 25 and the bottom end of the side wall of the limiting cavity 21 where the second buckle 23 is located, and no part of the side wall of the limiting cavity 21 is left below the second notch 25, so that the second buckle 23 is prevented from being too hard, so that the second buckle 23 may have larger hardness, but not too hard, but also has a certain elasticity, so that on the basis of realizing the firm engagement between the second buckle 23 and the heat exchange tube 201, the elasticity of the second buckle 23 is increased as much as possible, and the assembly convenience of the second buckle 23 and the heat exchange tube 201 is improved, so that the evaporator bracket 10 can better compromise the assembly convenience and the limiting firmness.

In the foregoing embodiments, the relative arrangement relationship between the first buckle 22 and the second buckle 23 in the limiting portion 2 may be varied.

For example, referring to fig. 3, in some embodiments, the first catches 22 and the second catches 23 in the limit portion 2 are alternately arranged in the first direction, that is, the first catches 22 and the second catches 23 are arranged in the first direction in such a manner that one first catch 22, one second catch 23, one further first catch 22, one further second catch 23, … …, and so on. By adopting the mode that the strong and weak buckles are alternately arranged along the first direction, the evaporator bracket 10 can better consider the assembly convenience and the limiting firmness, the assembly efficiency of the evaporator assembly 100 and the refrigeration equipment is more effectively improved, and the structural reliability of the evaporator assembly 100 and the refrigeration equipment is improved.

For another example, referring to fig. 3, in some embodiments, the first clasp 22 projects from a sidewall of the spacing cavity 21 toward a first side in a second direction, and the second clasp 23 projects from a sidewall of the spacing cavity 21 toward a second side opposite the first side in the second direction. Wherein the second direction is perpendicular to the first direction and the depth direction of the limiting cavity 21. If the first direction is referred to as the length direction of the spacing chamber 21, the second direction may be referred to as the width direction of the spacing chamber 21. This arrangement makes the protruding directions of the first catch 22 and the second catch 23 in the second direction opposite, that is, the first catch 22 and the second catch 23 protrude reversely in the second direction, so that the first catch 22 and the second catch 23 can lock the heat exchange tube 201 reversely, which is advantageous for increasing the fitting stability.

For another example, referring to fig. 3, in some embodiments, the spacing cavities 21 of the spacing portion 2 are divided into at least two groups, the at least two groups of spacing cavities 21 are sequentially arranged along the second direction, and the first buckle 22 and the second buckle 23 are disposed on sidewalls of the spacing cavities 21 of different groups. At this time, the first buckle 22 and the second buckle 23 in the same limiting part 2 are not collinear in the second direction, but are arranged in a staggered manner, if each group of limiting cavities 21 arranged in the second direction is called a row of limiting cavities 21, then at this time, the first buckle 22 and the second buckle 23 in the same limiting part 2 are positioned on the limiting cavities 21 in different rows, and under such a condition, the distribution of the first buckle 22 and the second buckle 23 is more reasonable, so that the assembly convenience and the limiting firmness can be better considered.

In the foregoing embodiments, the number of the first catches 22 and the second catches 23 in the limit portion 2 is not limited, and for example, the limit portion 2 may include one, two or more first catches 22 and one, two or more second catches 23. Wherein, when spacing portion 2 includes two at least first buckles 22 and at least one second buckle 23, make things convenient for evaporator support 10 to compromise convenient for the assembly better and spacing fastness.

In practice, it has been found that the evaporator stand 10 of the related art has the problems that the water is difficult to drain and the heat exchange tube 201 is easily corroded, in addition to the aforementioned problems that it is difficult to combine the convenience of assembly and the durability of limitation. Specifically, during the operation of the evaporator 20, condensed water is generated on the heat exchange tube 201, and the corresponding condensed water, especially water drops, is difficult to flow out by itself, is easy to be stored in the limiting cavity 21, corrodes the heat exchange tube 201, reduces the structural reliability, and shortens the service life.

To solve the above problem of difficult draining of the stored water, referring to fig. 3 to 4, in some embodiments, the limiting part 2 includes a drainage hole 26, and the drainage hole 26 is in communication with the limiting cavity 21 to guide the water in the limiting cavity 21 to flow out of the limiting cavity 21. The drainage holes 26 can guide water in the limiting cavity 21 to flow out timely and automatically, so that condensed water, particularly water drops, generated by the heat exchange tube 201 are effectively prevented from being corroded by the heat exchange tube 201 due to the fact that the water drops exist in the limiting cavity 21 for a long time, and further structural reliability is effectively improved, and service life is prolonged.

When the drainage holes 26 are provided, referring to fig. 3 and 4, the drainage holes 26 can be in one-to-one correspondence with the limiting cavities 21, so that water in each limiting cavity 21 can be timely discharged under the action of the corresponding drainage holes 26, and all heat exchange tubes 201 of the evaporator 20 are effectively prevented from being corroded.

In the foregoing embodiments, the number of the limiting portions 2 in the evaporator stand 10 may be one, two or more, for example, in some embodiments, the evaporator stand 10 may include at least two limiting portions 2, and in this case, the evaporator stand 10 may restrict at least two groups of heat exchange tubes 201 of the evaporator 20. Also, when the evaporator stand 10 includes at least two limiting portions 2, the relative positional relationship of the at least two limiting portions 2 may also be varied. For example, referring to fig. 3 and 4, in some embodiments, the evaporator stand 10 includes two limiting portions 2, and the two limiting portions 2 are connected in a V shape, where the evaporator stand 10 is particularly suitable for an evaporator 20 having two groups of heat exchange tubes 201 on one side and two groups of heat exchange tubes 201 on one side arranged in a V shape (which may be simply referred to as a V-shaped evaporator). Of course, when the evaporator 20 adopts other structures such as Z-type, C-type or G-type, the evaporator stand 10 can be designed accordingly.

In practice, it has been found that the related art evaporator stand 10 is also prone to generate abnormal noise due to friction with the water pan 30 and other parts due to expansion and contraction during the cooling or heating process. With respect to this, referring to fig. 3-4, and as can be seen in conjunction with fig. 1-2, in some embodiments, the outer side of the base 1 is provided with a bump 27, and the base 1 contacts the drip tray 30 via the bump 27. Due to the protruding points 27, the contact area between the evaporator support 10 and the water pan 30 can be reduced, friction is reduced, and therefore the problem that abnormal noise is generated due to mutual friction of the evaporator support 10 and the water pan 30 caused by thermal expansion and cold contraction can be effectively solved.

In the case where the bump 27 is provided on the outer side surface of the base 1, the bump 27 may be provided on only one of the upper and lower ends of the outer side surface of the base 1, or may be provided on the upper and lower ends of the outer side surface of the base 1, see fig. 6. Wherein, when the upper and lower both ends of the lateral surface of the base body 1 are all provided with the salient points 27, the two rows of salient points 27 at the upper and lower both ends can better support the evaporator support 10, so that the evaporator support 10 is more stable.

Further, in the embodiment where the upper and lower ends of the outer side surface of the base 1 are provided with the protruding points 27, referring to fig. 6, the protruding points 27 at the upper and lower ends of the outer side surface of the base 1 may be arranged in a staggered manner in the length direction of the outer side surface of the base 1, and at this time, the protruding points 27 at the upper and lower ends of the outer side surface of the base 1 are not vertically opposite, but are arranged in a staggered manner, which is beneficial in that the die opening is convenient and the processing is more convenient.

The evaporator stand 10 in the foregoing embodiments may be an injection molded evaporator stand, so that the evaporator stand 10 is less prone to rust than if the evaporator stand 10 were a sheet metal evaporator stand.

The application will be further described with reference to the embodiments shown in fig. 1-6.

As shown in fig. 1-6, in this embodiment, the evaporator assembly 100 includes an evaporator 20, a drip tray 30, and two evaporator brackets 10.

The evaporator 20 is a V-shaped evaporator, two groups of heat exchange tubes 201 are disposed on two sides of the length direction of the V-shaped evaporator, and V-shaped heat exchange tubes 201 are disposed between the two groups of heat exchange tubes 201 on each side. Each group of heat exchange tubes 201 includes three rows of heat exchange tubes 201, the three rows of heat exchange tubes 201 are sequentially arranged along the second direction, and each row of heat exchange tubes 201 includes three heat exchange tubes 201 sequentially arranged along the first direction, so that each group of heat exchange tubes 201 on a single side of the evaporator 20 has three rows and three columns, and 9 heat exchange tubes 201 are all arranged.

And, two rows of protruding points 27 are arranged on the outer side surface of the base body 1 facing the water receiving disc 30, the two rows of protruding points 27 are positioned at two ends (namely, upper and lower ends) of the base body 1 facing the height direction of the outer side surface of the water receiving disc 30, each row of protruding points 27 comprises at least two groups of protruding points 27 which are arranged at intervals along the length direction of the outer side surface of the base body 1 facing the water receiving disc 30, and meanwhile, the protruding points 27 in each group of protruding points 27 in the two rows are not opposite to each other up and down, but are arranged in a staggered manner. So, be equipped with two upper and lower rows of bump 27 that the position was arranged on the evaporimeter support 10, and these bump 27 constitute floating point bearing structure, both can steadily support evaporimeter support 10, effectively promote the structural stability of evaporimeter support 10, can realize the point contact between evaporimeter support 10 and the water collector 30 again, make can reduce the refrigeration or heat in-process through reducing the area of contact of evaporimeter support 10 and water collector 30, because of the expend with heat and contract with cold characteristic is different between evaporimeter support 10 and the water collector 30, the abnormal noise that the mutual friction produced.

The two limiting parts 2 are arranged on the base body 1, and the two limiting parts 2 are connected at an angle to form a V shape and correspond to the two groups of heat exchange tubes 201 on the single side of the evaporator 20 one by one so as to limit and restrain the two groups of heat exchange tubes 201 on the single side of the evaporator 20. As shown in fig. 1 to 6, in this embodiment, both of the stopper portions 2 protrude toward a direction away from the evaporator 20 from the base body 1, and each include three sets of stopper cavities 21, which are sequentially arranged along the second direction such that each stopper portion 2 includes three rows of stopper cavities 21, and wherein each row of stopper cavities 21 includes three stopper cavities 21 sequentially arranged along the first direction. Thus, each limiting portion 2 includes three rows and three columns, and the three rows and three columns include 9 limiting cavities 21, and the 9 limiting cavities 21 are in one-to-one correspondence with the three rows and three columns in each group of heat exchange tubes 201 on one side of the evaporator 20, and the 9 heat exchange tubes 201 can pass through the three rows and three columns in each group of heat exchange tubes 201 on one side of the evaporator 20 in one-to-one correspondence.

In this embodiment, as shown in fig. 3 to 6, each of the spacing cavities 21 has an oblong shape, the length direction and the width direction of which are along the first direction and the second direction, respectively, and which penetrates the evaporator stand 10 in the thickness direction of the evaporator stand 10, so that the depth direction of the spacing cavity 21 is along the thickness direction of the evaporator stand 10. When assembled with the evaporator 20, the U-shaped bent portion of the heat exchange tube 201 is inserted into the spacing cavity 21, and is restrained by the spacing cavity 21.

And, as shown in fig. 3 to 5, in this embodiment, each of the stopper portions 2 includes a first catch 22 and a second catch 23 for catching with the heat exchange tube 201, and the first catch 22 and the second catch 23 are provided on the side wall of the stopper cavity 21 in the two outermost sets of stopper cavities 21 along the second direction among the three sets of stopper cavities 21, in other words, the first catch 22 and the second catch 23 are provided on the side wall of the stopper cavity 21 in the two outermost sets of stopper cavities 21 along the second direction among the three sets of stopper cavities 21. In particular, as can be seen from fig. 3 to 5, in this embodiment, each stop portion 2 comprises two first catches 22 and one second catch 23. Wherein, two first buckles 22 all set up on the lateral wall of spacing chamber 21 in the spacing chamber 21 of first row along the second direction, and two first buckles 22 are located on the lateral wall of the spacing chamber 21 of first row along the different spacing chambers 21 that first direction arranged in proper order, are located on the lateral wall of the spacing chamber 21 of first row along the first direction first and the spacing chamber 21 of third in proper order. The second buckle 23 is disposed on a sidewall of the limiting cavity 21 in the third row of limiting cavities 21 along the second direction, and is specifically disposed on a sidewall of the second limiting cavity 21 in the first direction of the third row of limiting cavities 21. As such, the first snaps 22 and the second snaps 23 in each of the stopper portions 2 are alternately arranged in the first direction and are staggered in the second direction.

In this embodiment, as shown in fig. 3-4, the first buckle 22 and the second buckle 23 are disposed on one of two side walls of the corresponding limiting cavity 21, which are oppositely disposed along the second direction, and the first buckle 22 extends from the side wall of the corresponding limiting cavity 21 toward the first side of the second direction, and both sides of the first buckle 22 along the first direction are provided with first notches 24 which are not dug to the bottom, while the second buckle 23 extends from the side wall of the corresponding limiting cavity 21 toward the second side of the second direction, and only one side of the second buckle 23 along the first direction is provided with second notches 25 which are dug to the bottom. As such, the first and second catches 22 and 23 form weak and strong catches, respectively, and the first and second catches 22 and 23 are oppositely arranged in the second direction.

Through setting up spacing portion 2 to including weak buckle and strong buckle, and make weak buckle and the crisscross reverse arrangement of strong buckle, can effectively promote the assembly convenience and the combination fastness of evaporimeter support 10 and heat exchange tube 201 for evaporimeter support 10 can compromise assembly convenience and spacing fastness betterly.

Also, as shown in fig. 3 and 4, in this embodiment, one side of each of the limiting chambers 21 in the first direction is provided with a drainage hole 26. The drainage holes 26 penetrate through the evaporator stand 10 in the thickness direction of the evaporator stand 10 and communicate with the corresponding limiting chambers 21. In this way, the drainage hole 26 forms a drainage structure, so that water in the limiting cavity 21 can be led out, and condensed water generated by the heat exchange tube 201 is prevented from being stored in the limiting cavity 21 during refrigeration, so that the heat exchange tube 201 is prevented from being corroded.

It can be seen that, in this embodiment, the evaporator stand 10 is an injection molding evaporator stand, and has a strong and weak buckle structure (a first buckle 22 and a second buckle 23) and a drainage structure (a drainage hole 26) which are arranged in a staggered manner and a floating point support structure (a convex point 27), so that the problems that the evaporator stand is easy to rust, difficult to assemble and easy to fall off, a heat exchange tube is easy to corrode, and abnormal sound caused by expansion and contraction is easy to occur between the evaporator stand and a water receiving disc can be effectively solved, thus being beneficial to improving the assembly efficiency, improving the structural reliability, prolonging the service life, and further being beneficial to improving the product quality and improving the use experience of users.
