[0033] This invention provides a heat exchanger 1 for an ice-making device. The heat exchanger 1 includes at least one heat exchange unit 11, and each heat exchange unit 11 includes at least one heat exchange element 111. The heat exchange element 111 is sleeved on the ice-making component 2 of the ice-making device, thereby enabling the heat exchanger 1 to exchange heat with the ice-making component 2 through the heat exchange element 111, so as to cool the water in the ice-making component 2 and freeze it into ice. The number of heat exchange elements 111 in the heat exchange unit 11 corresponds to the number of ice-making components 2 in the ice-making device.

[0034] It should be noted that the number of heat exchange units 11 is not limited to one; it can be two, three, four, five, etc. The number of heat exchange components 111 is not limited to one; it can be two, three, four, five, etc.

[0035] Specifically, such as Figure 1 As shown, the heat exchanger 1 of the first construction method in the embodiment of the present invention includes a heat exchange unit 11, and the heat exchange unit 11 includes four heat exchange components 111.

[0036] In some specific embodiments, the heat exchanger 1 comprises a plurality of heat exchange units 11 and a connecting pipe 12, and two adjacent heat exchange units 11 are connected to each other through the connecting pipe 12.

[0037] Specifically, as shown in Figure 2 the second structure of the heat exchanger 1 in the embodiment of the utility model, the heat exchanger 1 comprises two heat exchange units 11 and a connecting pipe 12, the connecting pipe 12 is internally structured with a passage for the circulation of refrigerant, and the two heat exchange units 11 are communicated with each other through the connecting pipe 12.

[0038] Further illustrated is the heat exchanger 1 of the first structure in the embodiment of the utility model by taking the heat exchanger 1 of the first structure in the embodiment of the utility model as an example.

[0039] As shown in Figure 1 and Figure 3 , the heat exchanger 111 is internally structured with a refrigerant containing space 1113, and the refrigerant containing space 1113 is communicated with the compressor of the ice making device through a pipeline. In the case that the heat exchanger 111 is sleeved on the ice making component 2 of the ice making device, part of the ice making component 2 is placed in the refrigerant containing space 1113. Among them, the refrigerant containing spaces 1113 of two adjacent heat exchangers 111 in a single heat exchange unit 11 are communicated with each other, and the heat exchanger 111 located at one end of the heat exchange unit 11 is provided with a first port 112 communicated with the refrigerant containing space 1113, and the heat exchanger 111 located at the other end of the heat exchange unit 11 is provided with a second port 113 communicated with the refrigerant containing space 1113. Through the above-mentioned setting, under the driving action of the compressor, the refrigerant can enter the refrigerant containing space 1113 in the heat exchanger 111 through the first port 112 and flow out from the second port 113, or enter the refrigerant containing space 1113 in the heat exchanger 111 through the second port 113 and flow out from the first port 112, so that the refrigerant can be introduced into the refrigerant containing space 1113 and heat exchanged with the part of the ice making component 2 placed in the refrigerant containing space 1113.

[0040] Continuing to refer to Figure 1 and Figure 3 , the heat exchanger 111 is structured with a through hole 1111, and the upper opening and the lower opening of the through hole 1111 are located at the upper side and the lower side of the heat exchanger 111 respectively. The heat exchanger 111 can be sleeved on the ice making component 2 of the ice making device along the up-down direction through the through hole 1111.

[0041] In order to solve the problems of complex manufacturing process, long manufacturing time and high manufacturing cost of the heat exchanger 1 of the existing ice making device, as shown in Figure 4 and Figure 5As shown, the heat exchange member 111 includes a first part 111a and a second part 111b connected to each other and thus configured to form a refrigerant containing space 1113, and the first part 111a and the second part 111b are made by a stamping process.

[0042] With reference to Figure 4 and Figure 5 , the first part 111a and the second part 111b are welded into an integrated structure.

[0043] With reference to Figure 4 and Figure 5 , the first part 111a is provided with a first opening 1111a constituting an upper opening of the through hole 1111 by a stamping process, and the second part 111b is provided with a second opening 1111b constituting an upper opening of the through hole 1111 by a stamping process.

[0044] With reference to Figure 4 and Figure 5 , the first part 111a includes a first connecting site 1112a, and the second part 111b includes a second connecting site 1112b capable of being buckled with the first connecting site 1112a, and the radial dimension of the first connecting site 1112a is greater than the radial dimension of the second connecting site 1112b. Specifically, the inner diameter dimension of the first connecting site 1112a matches the outer diameter dimension of the second connecting site 1112b.

[0045] Through the above arrangement, when the first connecting site 1112a is buckled in the second connecting site 1112b, they can be closely matched to reduce the connection gap between the first part 111a and the second part 111b, and then fixedly connected by a welding process, thereby enhancing the sealing performance of the heat exchanger 1. In addition, the buckling design has a positioning function, so that the first part 111a and the second part 111b can be quickly aligned and fixed, not only saving the step of adjusting the position of the parts before welding, but also avoiding the risk of part deviation during the welding process, thereby improving the welding efficiency and effectively reducing the welding failure rate.

[0046] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the first part 111a and the second part 111b after connection are configured with an annular protrusion 1112 corresponding to the first connecting site 1112a and the second connecting site 1112b. Through the above arrangement, the part corresponding to the annular protrusion 1112 in the refrigerant containing space 1113 forms a flow channel structure for the flow of refrigerant, not only increasing the flow space of the refrigerant, but also optimizing the flow path of the refrigerant, thereby significantly improving the heat exchange efficiency.

[0047] In the technical scheme, the heat exchanger 1 is simplified in component composition through structure improvement, and the production efficiency is improved significantly compared with the scheme of preparing the related components by the casting process in the prior art. In addition, the technical scheme of the heat exchanger 1 does not need to manufacture the refrigerant inflow pipe and the refrigerant discharge pipe respectively, but directly forms the refrigerant containing space 1113 for the refrigerant circulation by connecting the first part 111a and the second part 111b. The design not only saves the step of welding the refrigerant inflow pipe and the refrigerant discharge pipe, further improves the production efficiency, reduces the welding position in the assembly process of the heat exchanger 1, enhances the sealing performance of the heat exchanger 1, improves the reliability and service life of the product, and reduces the manufacturing cost.

[0048] The utility model embodiment further provides an ice making assembly of an ice making equipment, and the ice making assembly comprises the heat exchanger 1 of the ice making equipment in any one of the above.

[0049] As Figure 6 and Figure 7 shown, the ice making assembly further comprises at least one ice making component 2, the ice making component 2 is in a hollow tubular structure, a flow channel 21 for water passing through is constructed in the ice making component 2, the ice making component 2 is arranged on the heat exchange piece 111 through the through hole 1111, so that part of the ice making component 2 is arranged in the refrigerant containing space 1113. Specifically, the ice making component 2 is welded with the heat exchange piece 111 as an integral structure. Through the above arrangement, when the ice making assembly executes the ice making program, under the driving action of the compressor, the low-temperature refrigerant is introduced into the refrigerant containing space 1113 and exchanges heat with the ice making component 2, so that the water in the flow channel 21 is cooled and frozen into ice on the inner side wall.

[0050] Alternatively, the heat exchanger 1 can further comprise a plurality of heat exchange units 11, each heat exchange unit 11 comprises at least one heat exchange piece 111, and adjacent heat exchange units 11 can be arranged in the vertical direction or arranged in parallel in the horizontal direction.

[0051] Specifically, as Figure 8 shown, the ice making assembly in the first structure of the utility model embodiment. In this embodiment, a plurality of ice making components 2 are arranged in the horizontal direction, the heat exchange units 11 are arranged in the vertical direction, and a plurality of heat exchange pieces 111 corresponding in the vertical direction are arranged on the same ice making component 2. Among them, the two adjacent heat exchange units 11 in the vertical direction are connected to each other through the connecting pipe 12.

[0052] In some specific embodiments, as Figure 9The ice making assembly in the second structure mode in the embodiment of the utility model is shown in the figure.

[0053] The utility model embodiment further provides a kind of ice making equipment, and ice making equipment includes the heat exchanger 1 of any one of above ice making equipment.

[0054] It can be understood that since the ice making equipment is configured with the heat exchanger 1 of the above ice making equipment, it has all the technical effects of the heat exchanger 1 of the above ice making equipment, which will not be repeated here.

[0055] In some specific embodiments, the ice making equipment includes the ice making assembly of any one of the above ice making equipment.

[0056] It can be understood that since the ice making equipment is configured with the ice making assembly of the above ice making equipment, it has all the technical effects of the ice making assembly of the above ice making equipment, which will not be repeated here.

Without deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical schemes after these changes or replacements will fall within the protection scope of the utility model.
