Description

Technical Field

[0001] The present invention relates to the technical field of evaporators, and in particular to an ice-making evaporator. Background Art

[0002] The working principle of an ice evaporator is as follows: the compressor delivers high-temperature, high-pressure gaseous refrigerant to the condenser, which condenses it into a high-pressure liquid. The high-pressure liquid then throttles the expansion valve and reduces its pressure, becoming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant then flows through the evaporator tube into the ice evaporator. The compressor drives the refrigerant through the evaporator tube, exchanging heat with the condensed water in the ice evaporator, which in turn condenses the condensed water in the ice tray into ice. Traditional ice evaporators often use a straight tube structure with a single copper tube distribution inside the evaporator. This results in a limited contact area between the refrigerant in the copper tubes and the ice tray, resulting in low heat exchange efficiency and requiring extended cooling time to complete ice production. To address this issue, commercially available ice evaporators often use layered or complex copper tube designs to increase the contact area between the copper tubes and the ice tray, thereby improving the ice production efficiency of the ice evaporator. However, this design makes the ice evaporator difficult to assemble and hinders subsequent maintenance.

[0003] It can be seen that the existing technology still needs to be improved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an ice-making evaporator having the advantages of simple assembly and high heat exchange efficiency, so as to overcome the shortcomings of the prior art.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] An ice-making evaporator includes an evaporator body and an evaporator pipe, characterized in that four bosses are evenly arranged on the bottom of the evaporator body, a channel is provided inside the bosses, and the evaporator pipe is composed of two mutually staggered and inclined evaporation tubes and an inlet and outlet pipe. The evaporation tube is connected to the internal channel of the evaporator body to form a continuous flow channel.

[0007] Furthermore, the inlet and outlet pipes are both arranged on the same side of the evaporator body.

[0008] Furthermore, an ice making groove is provided in the evaporator body, and partitions are arranged at intervals in the ice making groove. A avoidance opening is provided on the top of the partition, and the partitions divide the ice making groove into several ice grids.

[0009] Furthermore, the cross section of the ice making groove is fan-shaped and centrally symmetrical.

[0010] Furthermore, the evaporator body is made of extruded profiles.

[0011] A method for preparing an ice-making evaporator comprises the following steps:

[0012] S1) pre-treating the blank, and extruding the blank into an evaporator body through an extrusion die;

[0013] S2) placing the extruded blank into a CNC machine tool, milling the evaporator to complete the processing of the ice tray and the avoidance port;

[0014] S3) drilling the blank processed in step 2 to complete the channel (3);

[0015] S4) welding an evaporator pipe at the outlet of the channel (3) of the evaporator body (1) so that the evaporator pipe is in communication with the internal channel (3) of the evaporator body (1).

[0016] The above technical solution has the following beneficial effects:

[0017] The present invention saves installation space by arranging the evaporator tubes in an inclined and staggered manner. Compared with evaporator tubes arranged vertically or horizontally in parallel, the inclined and staggered arrangement can arrange longer pipes in the same volume, extend the flow time of the refrigerant in the channel, allow the refrigerant to have a longer time to exchange heat in the channel, and improve the heat exchange efficiency per unit volume.

[0024] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0025] See also Figure 1-Figure 3 As shown, the present invention discloses an ice-making evaporator, including an evaporator body 1 and an evaporator pipe 2. Four bosses 14 are evenly arranged on the bottom of the evaporator body 1. The bosses reduce the weight of the evaporator body 1, and the arrangement of two horizontal bosses 14 enables the evaporator body 1 to be placed stably on a horizontal plane. A channel 3 is provided inside the boss 14, so that the refrigerant can circulate inside the evaporator body 1. The evaporator pipe 2 is two evaporation tubes 21 that are staggered and inclined with respect to each other. The evaporation tube 21 is connected to the internal channel 3 of the evaporator body 1 to form a continuous flow channel. When a user needs to make ice, the compressor delivers high-temperature, high-pressure gaseous refrigerant to the condenser. The condenser condenses the high-temperature, high-pressure gaseous refrigerant into a high-pressure liquid. The high-pressure liquid then throttles the expansion valve and reduces its pressure, becoming a low-temperature, low-pressure liquid refrigerant. This low-temperature, low-pressure liquid refrigerant then flows through the evaporator tube 21 into the internal channel 3 of the ice-making evaporator. The compressor drives the refrigerant to circulate within the evaporator tube 21, exchanging heat with the water in the ice-making evaporator. The refrigerant absorbs the water's heat and evaporates into a gas, causing the water in the evaporator body 1 to freeze upon cooling. Compared to vertical or horizontal parallel evaporator tubes 21, the staggered arrangement not only allows for longer pipes within the same volume, but also prolongs the refrigerant's flow time within channel 3, allowing the refrigerant to exchange heat there for a longer period of time, improving heat exchange efficiency and making ice more efficient. This layout also ensures a more uniform temperature across the evaporator body.

[0026] The inlet and outlet pipes 22 are arranged on the same side of the evaporator body 1 and the evaporation tube 21, which can effectively utilize limited space, improve the integration of the ice-making evaporator, make the entire device more compact, and reduce space occupancy.

[0027] The ice making groove 11 is provided in the evaporator body 1, and the compartment in the ice making groove 11 is provided with a partition 12. The partition 12 divides the space in the ice making groove 11 into a plurality of ice trays of the same size, so that the user can get ice cubes of the same size when making ice. The partition 12 is provided with an avoidance opening 13. When the ice making evaporator finishes ice making, the compressor reverses and enters the heating mode. By changing the flow direction of the refrigerant, the high-temperature and high-pressure gaseous refrigerant originally flowing from the compressor to the condenser is directly introduced into the channel 3 in the evaporator body 1 through the evaporation tube 21. The high-temperature and high-pressure gaseous refrigerant releases heat in the channel 3 of the evaporator body 1, causing the temperature of the evaporator body 1 to rise rapidly, forming a temperature difference gradient with the ice layer in the ice making groove 11, which facilitates the de-icing of the ice cubes in the ice tray. The paddle 4 can pass through the avoidance opening 13 provided on the partition 12, and the ice in the ice tray is pushed out by the paddle 5 provided on the paddle 4, thereby realizing the de-icing of the ice making evaporator.

[0028] The ice trough 11 has a fan-shaped cross-section and is symmetrically centered. When the evaporator heats and defrosts, ice melts simultaneously on both sides of the curved surface within the ice tray, promoting even ice shedding within the tray and increasing the evaporator's defrosting efficiency. Furthermore, compared to conventional "mouth"-shaped ice trays, the smooth U-shaped ice tray allows condensed water to flow naturally along the curved surface, reducing dead corners where ice forms.

[0029] The evaporator body is made of extruded profiles, with the evaporator body 1 and spacer 12 fused into a single component. This eliminates the traditional interface between the ice trough 11 and the evaporator that requires welding or mechanical connection, reducing assembly complexity and facilitating subsequent maintenance. Furthermore, the one-piece injection molding process ensures a perfect fit between the ice tray and the evaporator surface, eliminating the gap between the traditional ice trough 11 and the evaporator. This allows the refrigerant to directly contact the ice tray within the ice trough 11 through the channel 3 of the evaporator body 1, reducing the thermal resistance of the intermediate medium (such as water or air), improving heat exchange efficiency, and significantly shortening ice-making time.

[0030] In order to facilitate those skilled in the art to implement the present invention, a method for manufacturing the above-mentioned evaporator is also provided, comprising the following steps:

[0031] S1) pre-treating the blank, and extruding the blank into an evaporator body through an extrusion die;

[0032] S2) placing the extruded blank into a CNC machine tool, milling the evaporator to complete the processing of the ice tray and the avoidance port;

[0033] S3) drilling the blank processed in step S2 to complete the channel 3;

[0034] S4) Welding an evaporator pipe at the outlet of the channel 3 of the evaporator body so that the evaporator pipe is connected to the internal channel 3 of the evaporator body.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
