Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum flat plate evaporators, in particular to a novel aluminum flat plate evaporator for quick freezing. Background Art

[0002] Aluminum heat exchange plate tube is a kind of efficient heat exchange equipment, made of aluminum alloy material, with good thermal conductivity, light weight, corrosion resistance and other characteristics. In quick freezing equipment, aluminum heat exchange plate tube is often used for quick freezing and cooling of food. The refrigerant flows in the tube to exchange heat with the food, so as to achieve rapid cooling of the food.

[0003] For example, a Chinese patent with publication number CN212914558U discloses an energy-saving aluminum flat plate evaporator structure, including an evaporator body, the lower end of which is connected to an inlet pipe, and the upper end of which is connected to a straight pipe. The utility model installs a round seat at the lower end of an upper aluminum plate, and a fastening screw passes through the outer end of the upper aluminum plate, and a round groove embedded in the round seat is provided at the upper end of the lower aluminum plate, and a fastening nut is connected to one end of the fastening screw passing through the threaded hole. This structure can easily separate the upper aluminum plate and the lower aluminum plate by loosening the fastening nut and then moving the round seat out of the round groove.

[0004] Although the above-mentioned aluminum flat plate evaporator solves the problem of replacing the evaporator tube, the tube wall of the existing evaporator tube is usually a smooth surface. Due to the surface characteristics of the smooth surface, there is a large resistance during heat transfer, resulting in poor heat exchange effect, and thus the overall heat exchange efficiency cannot be fully guaranteed, which not only affects the operating efficiency of the equipment, but may also increase energy consumption to a certain extent. In addition, when laid on a longer frame, adjacent aluminum flat plate evaporators are not easy to combine and connect, and are prone to deviation, which is not conducive to the refrigeration of food. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a novel aluminum flat plate evaporator for quick freezing to solve the problems in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A novel aluminum flat plate evaporator for quick freezing comprises an aluminum plate body, a heat exchange tube is fixedly connected to the inside of the aluminum plate body, the inner wall of the heat exchange tube is provided with heat exchange tooth patterns, a heat exchange tooth plate is fixedly connected to the lower side of the aluminum plate body, a first fixed block is fixedly connected to one end of the aluminum plate body, a slide groove is provided on one side of the first fixed block, a second fixed block is fixedly connected to the other end of the aluminum plate body, a slider is fixedly connected to one side of the second fixed block, the slider is slidably connected to the slide groove, and a clamping assembly is provided between the slider and the slide groove.

[0008] As a preferred technical solution, the clamping assembly includes a spring, which is installed on both sides of the inner part of the slide groove. One end of the spring is fixedly connected to a clamping block, and clamping holes are opened on both sides of the upper end of the slider, and the clamping block is movably connected to the clamping hole.

[0009] As a preferred technical solution, one end of the clamping hole is fixedly connected to a sliding rod, and a spring is sleeved on the sliding rod, and the sliding rod is slidably connected to one side of the inner part of the sliding groove.

[0010] As a preferred technical solution, a guide block is fixedly connected to the lower side of the clamping block in the slide groove, a guide groove is provided on the lower side of the clamping hole of the sliding block, and the guide block is slidably connected to the guide groove.

[0011] In summary, the utility model mainly has the following beneficial effects:

[0012] First, quick-frozen food is placed on an aluminum plate, with heat exchange teeth arranged inside and heat exchange fins arranged on the outer wall. When the heated refrigerant flows in the heat exchange tube, it will contact the heat exchange teeth to transfer cold. The heat exchange teeth increase the contact area between the inner wall of the heat exchange tube and the refrigerant, and improve the cold transfer efficiency. At the same time, the heat exchange teeth will also disturb the refrigerant flowing in the tube to form turbulence, so that the refrigerant can be fully mixed and fully contacted with the inner wall, thereby improving the heat exchange coefficient of the evaporator and improving the problem of low heat exchange efficiency of the evaporator.

[0013] Second, a first fixed block and a second fixed block are respectively fixed on both sides of the aluminum plate body, a slide groove is provided on the first fixed block, a slider is fixed on the second fixed block, the slider slides into the slide groove, so that adjacent aluminum plates are conveniently connected, and the slider is fixed to the slide groove through a clamping assembly to fix the adjacent aluminum plates, thereby preventing the aluminum plates from being displaced during installation, which is conducive to the placement of quick-frozen foods.

Through the above arrangement, the heat exchange coefficient of the evaporator is improved, the problem of low heat exchange efficiency of the evaporator is improved, and the cold in the refrigerant can be quickly transferred to the food to achieve rapid cooling of the food. Placing quick-frozen goods on the upper side of the aluminum heat exchange plate tube can make full use of the heat exchange efficiency of the aluminum heat exchange plate tube and improve the quick freezing efficiency.

[0020] With reference to 2-3, the clamping assembly 13 includes a spring 132, which is installed on both sides of the interior of the slide slot 10, one end of the spring 132 is fixedly connected to a clamping block 131, and clamping holes 134 are provided on both sides of the upper end of the slider 12, the clamping block 131 is movably connected to the clamping hole 134, one end of the clamping hole 134 is fixedly connected to a sliding rod 133, and the spring 132 is sleeved on the sliding rod 133, and the sliding rod 133 is slidably connected to one side of the interior of the slide slot 10; by setting the clamping assembly 13, when the slider 12 is connected to the slide slot 10, the clamping block 131 is squeezed and the spring 132 is deformed, and when the clamping block 131 is aligned with the clamping hole 134, the spring 132 recovers its deformation, and the clamping block 131 enters the clamping hole 134, so that the slider 12 is fixed to the slide slot 10, thereby fixing the adjacent aluminum plates, and setting the sliding rod 133 so that the clamping block 131 can move stably without deviation under the action of the spring 132.

[0021] refer to Figure 1-2 A guide block 15 is fixedly connected to the lower side of the clamping block 131 in the slide groove 10, and a guide groove 14 is opened on the lower side of the clamping hole 134 of the slider 12, and the guide block 15 is slidably connected to the guide groove 14; by providing the guide block 15 and the guide groove 14, it is used to guide the clamping block 131 to clamp with the clamping hole 134, thereby facilitating the connection between the slider 12 and the slide groove 10.
