Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration unit equipment, and in particular relates to an evaporator tube bundle slideway. Background Art

[0002] The evaporator is the main component of the refrigeration unit. In the evaporator, the heat in the indoor air is absorbed into the refrigerant, and the refrigerant changes from liquid to gas. The compressor compresses the low-pressure refrigerant gas into high-pressure gas, which is then condensed into high-pressure medium-temperature refrigerant liquid through the condenser. The liquid refrigerant is depressurized by the expansion valve and returns to the evaporator to complete the cycle.

[0003] Problems and disadvantages of the existing evaporator slide structure:

[0004] 1. The evaporator tube bundle is heavy, some weighing as much as 40 or 50 tons. Some evaporators have a high tube layout rate, and the space below the tube bundle is small. The conventional roller slide takes up a large space and has a complex structure. It cannot meet installation requirements when there is insufficient space below.

[0005] 2. The contact surface of the round steel slide and the plate slide is too small and the strength is insufficient. The slide itself will be directly worn away during pulling, resulting in wear to the support plate, making extraction difficult and even scratching the heat exchange tube in severe cases.

[0015] In one embodiment of the present invention, the tube bundle support plate is arranged outside the extractable tube bundle, and the tube bundle support plate and the extractable tube bundle are detachably connected.

[0016] In an embodiment of the present invention, the material of the slideway reinforcing rib plate is reinforcing ribs.

[0017] In an embodiment of the present invention, the slide support is welded on the evaporator shell.

[0018] In an embodiment of the present invention, the slideway is welded to the slideway reinforcing rib plate.

[0019] The beneficial effects of the utility model are:

[0020] First, the present application develops an evaporator tube bundle slideway with a simple structure, a small space occupied at the bottom, and an easily adjustable slideway size, which can be assembled based on existing plates.

[0021] Second, the present application increases the contact surface between the slide and the slide support, so that the slide is not easily damaged and can play a role in stabilizing the tube bundle support plate.

[0022] Third, the present application evenly adds slideway reinforcement ribs in the middle of the slideway, which can effectively ensure the strength of the slideway and prevent it from deforming or breaking due to its heavy weight.

[0023] Fourth, based on the previous points, the slide of the present application has lower labor and material costs, the slide size is more flexible, and the production cost can be reduced by 10%.

[0024] In summary, the evaporator tube bundle slideway of the present application has a simple structure and high strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1

[0030] Reference Figure 1 The evaporator tube bundle slide is applied to the evaporator. The evaporator includes an evaporator shell 3. An evaporator tube box 1 is installed at the left end of the evaporator shell 3. A transversely placed extractable tube bundle 2 is arranged in the evaporator shell 3. The extractable tube bundle 2 is a heat exchange tube bundle. The evaporator tube box 1 and the evaporator shell 3 clamp or fix the extractable tube bundle 2 by bolts.

[0031] Reference Figure 2 A plurality of slide supports 7 are symmetrically welded inside the bottom of the evaporator shell 3. The slide support 7 is L-shaped or right-angled. The slide support 7 has a short side and a long side. The short side is vertically welded inside the evaporator shell 3, and the long side is obliquely installed inside the evaporator shell. A slide 6 is installed on the long side. The slide is U-shaped, and the U-shaped bottom is connected to the long side of the slide support.

[0032] Reference Figure 2 The slideway 6 is welded with the slideway reinforcement rib plate 5, which is a reinforcement rib to enhance the strength of the slideway 6. The slideway reinforcement rib plate 5 does not affect the sliding performance of the slideway 6. The slideway 6 is welded with the tube bundle support plate 4, and the tube bundle support plate 4 and the slideway 6 are welded into one. The slideway 6 is connected to the extractable tube bundle 2 in a sliding manner, for example, the extractable tube bundle 2 is provided with a slide bar, and the slide bar can slide in the slideway 6, but is not limited to this sliding connection method.

[0033] The working process of the evaporator tube bundle slide is: when the extractable tube bundle 2 is extracted, the evaporator tube box 1 needs to be removed first, and then the extractable tube bundle 2 is extracted from the left side to the outside of the evaporator shell 3 through the slide 6.

[0034] Example 2

[0035] Different from Example 1, refer to Figure 2 The slideway support 7 is also symmetrically installed at the lower part of the extractable tube bundle 2. Figure 2 In the cross section, a circle is constructed with the center point of the extractable tube bundle 2 as the center of the circle and the distance from the center point to the bottom of the slideway 6 as the radius. The angle formed by the midpoint of the two left-right symmetrical slideway reinforcing ribs 5 and the line connecting the center of the circle is 54°. The rest is the same as in Example 1.

[0036] Example 3

[0037] Different from Example 1 or Example 2, the tube bundle support plate 4 is outside the extractable tube bundle 2 and is detachably connected to the extractable tube bundle 2, further improving the stability of the extractable tube bundle 2 in the evaporator. When the extractable tube bundle 2 is extracted, the connector between the extractable tube bundle 2 and the tube bundle support plate 4 is disassembled. The rest is the same as Example 1 or Example 2.
