Description

Technical Field

[0001] This utility model relates to the field of ice-making technology, and in particular to a cube ice evaporator. Background Technology

[0002] Evaporators, as an important heat exchange device, play a key role in refrigeration and industrial production. Their efficient and stable operation is of great significance for ensuring production efficiency and product quality.

[0003] Evaporator working principle: The evaporator uses the vaporization process of refrigerant liquid to absorb heat from the object being cooled, thereby achieving the effect of lowering the temperature.

[0004] It belongs to the indirect heat exchanger type. The heat of the cooled medium is transferred to the refrigerant through the pipe wall or plate wall. The refrigerant evaporates at low temperature, carrying away the heat.

[0005] The current ice mold uses welded copper pipes at the bottom of the back. The refrigerant transfers heat through the copper pipe walls to the bottom of the ice mold, resulting in a loss of heat exchange efficiency and a relatively low efficiency.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a square ice evaporator that would have greater industrial application value. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a square ice evaporator.

[0008] The present invention relates to a square ice evaporator, comprising an ice grid plate, on which multiple baffles are arranged in an array to form ice-making troughs. The back of the ice grid plate has an integrally formed back plate, inside which there is a spiral flow channel, with raised partitions between the flow channels. The back plate is welded and fixed to the ice grid plate.

[0009] This type of ice evaporator replaces the refrigerant flow pipes with a one-piece molded back plate. The flow channels are used for refrigerant flow, allowing the refrigerant to directly contact the ice grid, thus improving heat exchange efficiency.

[0010] Furthermore, the outer side panel and partition of the back panel are sealed to the back of the ice grid by welding.

[0011] The outer side panel of the back panel and the middle partition are welded to the ice grid plate to seal them, so that the flow channel inside the back panel is in direct contact with the ice grid plate, ensuring heat exchange efficiency.

[0012] Furthermore, adapter pipes are fixed at both ends of the flow channel.

[0013] The connecting pipes at both ends of the flow channel are used for connection, facilitating the inflow and outflow of refrigerant.

[0014] Furthermore, the baffle on one side of the ice-making tank is inclined.

[0015] The primary baffle of the ice-making tank is inclined to facilitate the demolding of ice blocks.

[0016] Furthermore, the cross-section of the flow channel is semi-circular.

[0017] The cross-section of the flow channel is semi-circular, which increases the contact area between the refrigerant and the ice grid, thereby improving the ice-making efficiency.

[0018] Furthermore, the ice grid includes side panels around the perimeter and cross-shaped horizontal and vertical panels in the center. The side panels are extensions of the base plate and fold upwards to form a frame structure. The horizontal and vertical panels have inclined slots, which are used to connect the horizontal and vertical panels. After connection, a gap is formed between the horizontal and vertical panels at the connection point, and there is a gap between the two ends of the horizontal and vertical panels and the side panels.

[0019] Ice cube trays are formed by splicing together side panels, horizontal panels, and vertical panels, with gaps at the joints of the horizontal and vertical panels, as well as gaps between the horizontal and vertical panels and the side panels. These gaps facilitate air recirculation and make it easy to demold the ice cubes.

[0020] Furthermore, there is a gap at the connection between the side panels.

[0021] The gaps between the side panels are also for air recirculation, making it easier for ice cubes to be demolded.

[0022] There are through holes at the intersection of the bottom of the vertical and horizontal plates, and the through holes are located on both sides of the horizontal plate.

[0023] The through holes at the bottom of the vertical and horizontal plates are also to improve demolding efficiency.

[0024] By means of the above solution, the present invention has at least the following advantages: This square ice evaporator replaces the tubular structure for refrigerant flow with an integrally molded back plate, and the flow channel in the back plate can directly contact the ice grid plate, which improves the heat exchange efficiency and thus also improves the ice making efficiency.

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] See Figure 1 and Figure 2 The preferred embodiment of this utility model describes a square ice evaporator, which includes an ice grid plate 1, an ice-making tank 2 formed by multiple baffles arranged in an array on the ice grid plate 1, an integrally formed back plate 3 on the back of the ice grid plate 1, a spiral flow channel 4 inside the back plate 3, and raised partitions 5 between the flow channels 4. The back plate 3 is welded and fixed to the ice grid plate 1.

[0036] See Figure 1-3 This type of ice evaporator has multiple intersecting baffles on its ice grid plate 1. These baffles are spliced ​​together to form an array of ice-making tanks 2. An integrally formed back plate 3 is welded to the back of the ice grid plate 1. After the back plate 3 is welded, the refrigerant swirls and flows in the flow channel 4. The refrigerant directly contacts the back of the ice grid plate 1, improving the heat exchange efficiency and making ice faster.

[0037] Furthermore, the outer side panel 6 of the back panel 3 and the partition 5 are sealed to the back of the ice grid 1 by welding.

[0038] See Figure 2 The outer side of the back plate 3 is the surrounding plate 6, and the partition 5 is located between adjacent flow channel 4 segments. The surrounding plate 6 and the partition 5 are used for welding. The back plate 3 is completely welded to the ice grid plate 1, and the fixing effect is stable.

[0039] Furthermore, both ends of the flow channel 4 are fixed with adapter pipes 7.

[0040] The fixed transfer pipe 7 on the flow channel 4 is used for the inflow and outflow of refrigerant, forming a flow circulation.

[0041] Furthermore, the baffle on one side of the ice-making tank 2 is inclined.

[0042] One side baffle of the ice-making tank 2 is inclined. After the ice is formed, the inclination of one side makes it easy to demold the ice blocks and improves the demolding efficiency.

[0043] Furthermore, the cross-section of flow channel 4 is semi-circular.

[0044] The cross-section of the flow channel 4 is semi-circular with an open top. When the refrigerant fills the flow channel, the contact area between the refrigerant and the ice plate 1 is maximized, thereby improving the heat exchange efficiency.

[0045] See Figures 4-6 The interior of the ice tray 1 consists of multiple horizontal plates 9 and vertical plates 10 joined together. Each horizontal plate 9 and vertical plate 10 has a splicing slot 12. The spliced ​​internal panels are fixed to the base plate 11 by welding. The width of the slot 12 is slightly greater than the thickness of the horizontal plates 9 and vertical plates 10. Therefore, after splicing, there is a gap between the horizontal plates 9 and vertical plates 10, and there is also a gap between the ends of the horizontal plates 9 and vertical plates 10 and the side plates 8. These gaps facilitate air recirculation and make it easier for the ice to melt between the ice and the base plate 11 during the demolding operation, thus facilitating the demolding operation.

[0046] The side plate 8 is formed by folding the outside of the base plate 11 upwards. There is a gap between the two ends of the folded side plate 8, which is to facilitate the entry of air and improve the efficiency of ice block demolding.

[0047] The through holes at the bottom of the vertical plate 10 and the horizontal plate 9 span across both sides of the horizontal plate 9 at the junction, which improves the efficiency of water flow when the ice is demolded and facilitates the demolding operation.

[0048] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

[0050] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
