In addition, the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

In addition, it should be noted that, in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixed or fixed. It is a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication between two components. For those skilled in the art, the specific meaning of the above-mentioned terms in the present invention can be understood according to specific circumstances.

First, referring to Figure 1, in the prior art, affected by the irregular shape of the heat exchanger 2 and uneven stress distribution after the heat exchanger 2 is installed, the bottom plane of the heat exchanger 2 is not completely parallel to the horizontal plane after installation. It shows an irregular twist. Because the supporting boss 1 in the prior art is fixed, the plane of the supporting boss 1 and the bottom plane of the heat exchanger 2 show a certain clip after the heat exchanger 2 is installed. Angle a. In this case, the supporting force of the support boss 1 to the heat exchanger 2 is concentrated at the apex of the included angle a. During long-distance bumpy transportation, it is easy to cause the heat exchanger 2 to be worn out by the support boss 1. The phenomenon appears.

As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, in order to solve the problem that the bottom plane of the heat exchanger 2 of the existing air conditioner and the supporting boss 1 of the chassis 3 are eccentrically worn due to the angle, the heat exchanger 2 The problem of abrasion and leakage of the boss 1 supported by the chassis 3. The movable support assembly 4 of the present invention includes a supporting member 41 and a supporting protrusion 42. The supporting member 41 is provided with a supporting portion 412 and a movable portion. The supporting portion 412 is a flat surface. The heat exchanger 2 is pressed on the supporting part 412, the chassis 3 is provided with a supporting protrusion 42, the movable part is provided with an arc-shaped groove 413, and the supporting protrusion 42 is provided with an arc-shaped protrusion 422, an arc-shaped protrusion 422 Compatible with the arc-shaped groove 413, the arc-shaped groove 413 can be movably pressed on the arc-shaped protrusion 422.

As a preferred embodiment, the support member 41 is a steel product, and is cast or die-cast at one time. Of course, the support member 41 can also be a weather-resistant high-strength composite material or a special plastic.

The movable support assembly 4 is used as a load-bearing component to combine the heat exchanger 2 and the chassis 3 together. The support portion 412 of the support member 41 is used as a support plane to directly contact the heat exchanger 2 to provide supporting force, that is, the heat exchanger 2 relies on gravity. It is directly pressed on the support plane; the arc-shaped groove 413 is used as the sliding plane of the movable part, which coincides with the arc of the arc-shaped protrusion 422 of the support protrusion 42, so that the support member 41 can be adjusted adaptively through relative sliding. In order to keep the support plane always in contact with the bottom plane of the heat exchanger 2, that is, when the total force transmitted by the heat exchanger 2 to the support member 41 does not pass through the arc center of the arc-shaped protrusion 422, it can be in the heat exchanger 2 Under the action of gravity, a small circular sliding is made along the arc center of the arc-shaped convex portion 422, so that the heat exchanger 2 is uniformly stressed and the occurrence of eccentric wear is avoided. As a preferred embodiment, the chassis 3 and The supporting protrusion 42 is integrally formed.

In addition, in order to improve the eccentric wear phenomenon of the support boss 1 on the heat exchanger 2 and the chassis 3, the industry generally adopts the method of widening the support boss 1 or adding a welding auxiliary support platform, by increasing the heat exchanger 2 and the chassis 3 Support the contact area of the boss 1 to reduce the probability of eccentric wear. This method is based on the premise of sacrificing the anti-icing ability of the bottom of the heat exchanger 2 when the product is heated in winter. This case does not increase the support area At the same time, it can also achieve the purpose of reducing the occurrence of eccentric wear.

Continuing to refer to FIGS. 2, 3, 4, and 5, in a possible embodiment, a deformable cavity 4221 is provided in the arc-shaped protrusion 422, and/or; in the radial direction of the arc-shaped groove 413 Above, the end of the arc-shaped groove 413 and the support portion 412 form a transition end surface 411, and the transition end surface 411 is inclined toward the side of the arc center away from the arc-shaped groove 413. The support protrusion 42 is provided with a contact groove 421, which is The groove 421 is provided with the arc-shaped protrusion 422, the contact groove 421 is matched with the arc-shaped groove 413 and the transition end surface 411, and/or; the support member 41 is provided with a deformation cavity 4221 or a deformation groove. Those skilled in the art can understand that the arc-shaped groove 413 and the arc-shaped convex portion 422 of the present invention may be arc-shaped parts of a cylinder or an ellipse.

The advantage of the above arrangement is that the arrangement of the deformation cavity 4221 in the arc-shaped convex portion 422 and/or the deformation cavity or the deformation groove on the support member 41 can prolong the action time of the force through its own deformation, and can buffer the heat exchange. The impact force received by the heat exchanger 2 and kinetic energy are absorbed, so that damage to the pipeline caused by the heat exchanger 2 during a bumping process or a sudden drop can be avoided.

In addition, this arrangement can also increase the movable contact area between the supporting member 41 and the supporting protrusion 42. The movable contact area is the contact between the arc-shaped groove 413 on the supporting member 41, the transition end surface 411 and the supporting protrusion 42 The contact area between the grooves 421, in addition, the contact surface as a whole is roughly in a smooth transition W-shape, and the contact grooves 421 corresponding to the arc-shaped groove 413 and the transition end surface 411 can all play a certain limiting role. The supporting member 41 only slides in the contact groove 421, and the relative movement of the supporting member 41 with respect to the supporting protrusion 42 is restricted, thereby helping to maintain the stability between the supporting member 41 and the heat exchanger 2.

As shown in Figures 6 and 8, in a possible implementation, the arc-shaped protrusion 422 includes an arc-shaped protrusion body 4222 and a tile-shaped elastic member 4223. In the axial direction of the arc-shaped protrusion 422, the arc-shaped protrusion The two ends of the convex body 4222 are provided with installation grooves 4227, and the tile-shaped elastic member 4223 is arranged in the installation groove 4227.

The advantage of the above arrangement is that the tile-shaped elastic member 4223 is detachably installed in the installation groove 4227 on the arc-shaped convex body 4222, and it supports the supporting member 41 in a static state. In addition, when the box body falls Or when subjected to a sudden downward acceleration, the tile-shaped elastic member 4223 can release part of the stress through its own deformation, thereby slowing down the reaction force of the chassis 3 on the heat exchanger 2 and achieving the purpose of protecting the heat exchanger 2. In a preferred embodiment, the tile-shaped elastic member 4223 is made of high manganese steel.

Continuing to refer to FIG. 6, in a possible embodiment, a hollow portion 4228 is provided at the arc-shaped convex body 4222 corresponding to the tile-shaped elastic member 4223.

The advantage of the above arrangement is that the arrangement of the hollow part 4228 can drain the condensed water to the outside of the chassis 3, so as to prevent the condensed water of the heat exchanger 2 from collecting there, which will cause the phenomenon of freezing in winter; in addition, this arrangement The method has a simple structure, is easy to produce, and can reduce production costs.

As shown in Fig. 7 and with continued reference to Figs. 6 and 8, in a possible embodiment, in the radial direction of the arc-shaped convex portion 422, there is a second recess at both ends of the arc-shaped convex portion body 4222. A deformation gap 4224, and/or; a second deformation gap 4225 is left at the fitting position of the tile-shaped elastic member 4223 and the arc-shaped groove 413.

The advantage of the above arrangement is that when the tile-shaped elastic member 4223 is subjected to an external force, it will be elastically deformed, and the relative position of each part will change. When force is applied, the arc of the tile-shaped elastic member 4223 will become larger, and its two ends have a tendency to extend outward, and the height has a tendency to be compressed. Therefore, the setting of the first deformation gap 4224 and the second deformation gap 4225 can be It satisfies the deformation of the height and the length of the two ends of the tile-shaped elastic member 4223, provides a deformation space for it, thereby prolongs the action time of the force, and slows down the force that the heat exchanger 2 bears, so as to protect the heat exchanger 2 In addition, the first deformation gap 4224 can also limit the position of the tile-shaped elastic member 4223.

As shown in FIG. 8, in a possible implementation manner, in the axial direction of the arc-shaped protrusion 422, the two ends of the arc-shaped protrusion 422 are further provided with limiting protrusions 4226.

The advantage of the above arrangement is that the arrangement of the limiting protrusions 4226 at both ends of the arc-shaped protrusion 422 can limit the support member 41 and prevent the support member 41 from opposing the arc-shaped protrusion 422 along its axial direction. By moving, the stability between the movable support assembly 4 and the heat exchanger 2 can be improved.

In another possible implementation (not shown in the detailed drawings below), in the radial direction of the arc-shaped protrusion 422, the arc-shaped protrusion 422 is provided with a sliding rail, and the arc-shaped groove 413 is provided with a sliding rail. Sliding grooves adapted to the sliding rail; or, along the radial direction of the arc-shaped protrusion 422, both the arc-shaped protrusion 422 and the arc-shaped groove 413 are provided with protrusions, and the protrusions on the arc-shaped protrusion 422 and The convex strips on the arc-shaped groove 413 are interlaced with each other.

The advantage of the above arrangement is that the arrangement of the sliding groove and the sliding rail limits the support member 41 and restricts the stroke of the sliding path between the arc-shaped convex portion 422 and the arc-shaped groove 413, so that it is kept at Within a reasonable range, that is, the stroke can meet the sliding stroke of the supporting member 41 for adaptive adjustment of the force borne by the heat exchanger 2. In addition, the arc-shaped convex portion 422 and the arc-shaped groove 413 have mutually staggered protrusions. The arrangement of, can restrict the movement of the support member 41 along its axial direction, so as to improve the stability between the movable support assembly 4 and the heat exchanger 2.

In a possible embodiment, the movable part further includes a spring, which is connected between the arc-shaped groove 413 and the arc-shaped protrusion 422, or; the movable part further includes a universal ball, which is fixed to the arc-shaped protrusion On the part 422, and slidingly connected with the arc-shaped groove 413, or; the arc-shaped groove 413 and the arc-shaped convex part 422 are coated with lubricant.

By applying lubricant or setting universal balls between the arc-shaped groove 413 and the arc-shaped protrusion 422, the friction coefficient between the arc-shaped groove 413 and the arc-shaped protrusion 422 can be reduced, so that the support member 41 is When the heat exchanger 2 is installed for the first time, the adaptive self-adjustment is completed smoothly. As a preferred embodiment, the lubricant can be silicone oil, lubricating oil, lubricating powder or even water. In addition, as another embodiment, The spring can be deformed to achieve the adaptive self-adjustment effect of the supporting member 41.

In a possible implementation, as shown in FIG. 9, the cross section of the heat exchanger 2 is elongated, and the supporting member 41 is provided in the middle of the elongated heat exchanger 2; or, as shown in FIG. 10 , The cross section of the heat exchanger 2 is L-shaped, the long side length of the L-shaped cross section is L1, the supporting member 41 is arranged on the long side, and the distance to the bend of the L-shaped cross section is 1/5L1 -2/5L1; or, as shown in Figure 11, the cross section of the heat exchanger 2 is U-shaped, the length of the middle bending section of the U-shaped cross section is L2, and the two supporting members 41 are arranged in the middle bending section And the distance to both ends of the middle bending section is 1/6L2-1/5L2; or, as shown in Figure 12, the cross section of the heat exchanger 2 is a quadrilateral with a missing bending section, and the quadrilateral cross-section includes One complete long side and one complete short side. The length of the complete long side is L3, and the length of the complete short side is L4. The two supporting members 41 are arranged on the complete long side and reach two ends of the complete long side. The distance between the ends is 1/6L3-1/5L3, the supporting member 41 is also arranged on the complete short side, and the distance to the inflection point of the incomplete long side is 1/6L4-1/5L4, where the supporting member is arranged The position can refer to the circle in Figure 9 to Figure 12.

The advantage of the above setting method is that for different types of heat exchangers 2, the relative positions of the movable support assembly 4 of the chassis 3 are different, that is, according to the specific type of heat exchanger 2, according to the force analysis and specific wear and leakage cases, analysis Draw out the area prone to wear and leakage, and use the minimum number of movable support components 4 to be set in this area, and the rest of the area uses the fixed support boss 1 in the prior art, so that the bottom plane of the heat exchanger 2 and the support portion 412 The plane is in full contact to prevent partial wear of the support state, reduce the wear and leakage of the heat exchanger 2 pipeline, and also reduce the production process and cost. Of course, the remaining areas can also be used with more than the minimum number of movable support components 4 , And even completely replace the movable support assembly 4 of the invention, so as to achieve a better anti-eccentric wear effect.

The operation mode of the present invention includes: the chassis 3 is positioned horizontally during in-line production, and when the supporting member 41 is installed for the first time, a brush is used on the sliding surface between the supporting member 41 and the supporting protrusion 42 to apply a layer of lubricant to reduce the coefficient of friction, for example Silicon oil is then placed on the support protrusion 42 of the chassis 3. At this time, the support member 41 is in a natural state by gravity; when the heat exchanger 2 is hoisted to the chassis 3 for the first time, certain stress concentration is likely to produce a fixed type of partial wear.
