Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically an evaporator used in a cold storage refrigeration system. Background Technology

[0002] A cold storage evaporator is an evaporator used in refrigeration equipment such as cold storage rooms. It is a type of indirect heat exchange device. Its principle is that a low-temperature, low-pressure liquid refrigerant vaporizes and absorbs heat on one side of the heat transfer wall of the evaporator, thereby cooling the medium on the other side of the heat transfer wall. The medium being cooled is usually water or air.

[0003] Chinese patent CN208832780U discloses an evaporator for a cold storage refrigeration system. This device heats a heat-conducting plate via an electric heater, and the plate moves outside the evaporator tube to melt frost. However, due to factors such as airflow, differences in surface characteristics, and uneven temperature distribution, the thickness of frost solidification varies across different parts of the evaporator tube. Since the diameter of the through-holes in the heat-conducting plate is fixed, when it moves to a recessed area of ​​frost, it cannot contact the frost, and heat is transferred to the frost via airflow, reducing the melting effect. When it moves to a raised area of ​​frost, it collides with the heat-conducting plate, hindering its movement. If the obstruction is significant, it can easily cause damage to the heat-conducting plate. This force, when transmitted to the cylinder, can also affect the cylinder, resulting in low practicality of the device.

[0004] Based on this, the present invention proposes an evaporator for a cold storage refrigeration system. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes an evaporator for a cold storage refrigeration system. The hemispherical structure of the contact portion decomposes the impact force of frost, allowing the push rod to slide into the mounting hole, thus buffering the impact and preventing damage to the heat-conducting plate and electric push rod from excessive impact. Furthermore, the contact portion automatically avoids protrusions and extends under spring action when encountering depressions, always remaining in close contact with the frost surface. Combined with continuous heat conduction, this achieves efficient melting of uneven frost, thereby improving its practicality.

[0006] The technical solution to achieve the purpose of this utility model is: an evaporator for a cold storage refrigeration system, including a base, a movable plate slidably connected to the base, a heat-conducting plate fixedly connected to the movable plate, and further comprising;

[0007] The heat-conducting plate has multiple mounting holes, and multiple heat-conducting pipes are slidably connected to each of the multiple mounting holes. Multiple springs are fixedly connected to each of the multiple heat-conducting pipes, and the multiple springs are fixedly connected to the multiple mounting holes.

[0008] Preferably, the heat pipe includes a rod portion and a contact portion, wherein multiple rod portions are fixedly connected to multiple springs, and multiple contact portions are fixedly connected to multiple rod portions.

[0010] Preferably, two housings are fixedly connected to the base, and two connecting pipes are fixedly connected to each of the two housings, with the connecting pipes communicating with the interior of the housing.

[0012] Preferably, an electric heater is fixedly connected to the movable plate, and the electric heater is electrically connected to the heat-conducting plate.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] In this invention, the hemispherical structure of the contact part can decompose the impact force of frost, push the rod part into the mounting hole, buffer the impact force, and avoid the heat conduction plate and electric push rod from being subjected to large impact force and causing damage. Secondly, the contact part automatically avoids protrusions and extends under the action of springs when encountering depressions, always sticking to the surface of frost. With continuous heat conduction, it can achieve efficient melting of uneven frost, thereby improving its practicality. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved evaporator for a cold storage refrigeration system. The technical solution of this utility model is as follows:

[0025] like Figures 1-5 As shown, an evaporator for a cold storage refrigeration system includes a base 1, a movable plate 2 slidably connected to the base 1, a heat-conducting plate 7 fixedly connected to the movable plate 2, and further includes;

[0026] Multiple mounting holes 8 are provided inside the heat-conducting plate 7. The mounting holes 8 are arranged in a linear array on the heat-conducting plate 7. Multiple heat-conducting pipes are slidably connected to the multiple mounting holes 8. Multiple springs 11 are fixedly connected to the multiple heat-conducting pipes. The multiple springs 11 are fixedly connected to the multiple mounting holes 8. The hemispherical structure of the contact part 10 can decompose the impact force of frost. The push rod part 9 slides into the mounting hole 8 to buffer the impact force and avoid the heat-conducting plate 7 and electric push rod 14 from being subjected to large impact forces and causing damage. In addition, the contact part 10 automatically avoids protrusions and extends under the action of springs 11 when encountering depressions, always sticking to the surface of frost. With continuous heat conduction, it can achieve efficient melting of uneven frost.

[0027] Furthermore, such as Figures 2-5 As shown, the heat pipe includes rods 9 and contact parts 10. Multiple rods 9 are fixedly connected to multiple springs 11, and multiple contact parts 10 are fixedly connected to multiple rods 9. The cross-section of the contact part 10 is semi-circular.

[0028] Furthermore, such as Figure 1 As shown, a sliding groove 12 is provided on the base 1, and a slider 13 is slidably connected in the sliding groove 12. The slider 13 is fixedly connected to the moving plate 2. The sliding groove 12 and the slider 13 cooperate to make the moving plate 2 move more stably. An electric push rod 14 is fixed on the base 1 by bolts, and the output shaft of the electric push rod 14 is fixed on the moving plate 2 by bolts.

[0029] Furthermore, such as Figure 1 As shown, two housings 3 are fixedly connected to the base 1, and two connecting pipes 4 are fixedly connected to the two housings 3 respectively. The connecting pipes 4 are connected to the inside of the housings 3, and steam is input into the housings 3 through the connecting pipes 4.

[0030] Furthermore, such as Figures 1-5 As shown, multiple evaporation tubes 5 are fixedly connected between the two shells 3. The evaporation tubes 5 are connected to the inside of the shells 3 and are arranged in a linear array on the shells 3.

[0031] Furthermore, such as Figure 1 As shown, an electric heater 6 is fixedly connected to the movable plate 2. The electric heater 6 is electrically connected to the heat-conducting plate 7. The electric heater 6 converts electrical energy into heat energy to heat the heat-conducting plate 7.

[0032] The specific working method is as follows: When in use, the electric push rod 14 is turned on, and the electric push rod 14 extends or retracts, pushing the moving plate 2 to move along the slide groove 12. At the same time, the electric heater 6 is turned on. After the electric heater 6 is powered on, it starts to work, converting electrical energy into heat energy. Since the electric heater 6 is electrically connected to the heat-conducting plate 7, the electric heater 6 heats the heat-conducting plate 7, causing the temperature of the heat-conducting plate 7 to gradually rise. The heat is conducted to the contact part 10 through the rod part 9, which is in close contact with the inner wall of the mounting hole 8. The contact part 10 is used to heat and melt the frost. When the moving plate 2 moves the heat-conducting plate 7 and the heat-conducting pipe, the contact part 10 first contacts the frost on the surface of the evaporating pipe 5. If it encounters a raised frost, the hemispherical curved surface of the contact part 10 will generate a reaction force along the normal direction of the hemispherical surface at that point and pointing towards the center of the sphere. This reaction force can be decomposed into a component force inclined towards the mounting hole 8, pushing the rod part 9 to overcome the elastic force of the spring 11 and slide into the mounting hole 8. Inside hole 8, during this process, the contact part 10, with its own spherical structure, converts the force applied by the frost into a tendency to move towards the mounting hole 8, precisely adjusting the contact position with the frost. When the contact part 10 moves past the protruding frost to the recessed frost, the originally compressed spring 11 loses the obstruction of the frost and begins to release elastic potential energy. The spring 11 pushes the rod part 9 to slide out of the mounting hole 8, causing the contact part 10 to extend to the recessed area, ensuring that the contact part 10 always maintains contact with the frost surface and continuously heats the frost. During the movement of the contact part 10 on the uneven frost surface, the contact part 10 absorbs the heat transferred by the heat-conducting rod and conducts the heat to the frost surface through direct contact with the frost. Under the heating and squeezing action of the contact part 10, the protruding frost gradually melts, and the frost in the recessed area also melts rapidly under the continuous heating of the contact part 10. After melting is complete, the heater and electric push rod 14 can be turned off.
