Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to an electric heating evaporator. Background Technology

[0002] In existing technologies, most evaporators with electric heating incorporate heating elements and refrigerant pipes within an oil cylinder containing heat transfer oil. Heat is transferred from the heating elements to the heat transfer oil, which in turn transfers heat to the refrigerant pipes for refrigerant heating. However, using heat transfer oil presents several drawbacks: the oil needs replacement when it expires, and thermal expansion and contraction of the oil affects the cylinder's lifespan. To ensure safety, numerous accessories such as safety valves, drain valves, and monitoring probes are required, resulting in a complex structure and increased costs. Furthermore, the heating elements, constantly immersed in liquid, are prone to leaks and potential safety hazards. Another approach involves casting the heating elements and refrigerant pipes within an aluminum block, preventing direct contact and allowing heat exchange through the aluminum block. However, the heating elements and refrigerant pipes are not removable or replaceable, and the limited refrigerant piping area leads to low efficiency. High-power evaporators are also bulky and expensive.

[0003] Therefore, it is necessary to provide an electrically heated evaporator to overcome the defects mentioned above. Utility Model Content

[0033] In order to more clearly illustrate the technical scheme in the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application, and those skilled in the art can obtain other drawings and other embodiments according to these drawings without creating any creative labor.

[0034] Referring to Figure 1 and Figure 2 , the embodiment provides an electric heating evaporator, which comprises a heating plate 10, a spoiler fin 20 and a cover plate 30 arranged in sequence along a first direction X. The heating plate 10 is provided with a heating channel 103, and the heating channel 103 is provided with an electric heating pipe. The surface of the heating plate 10 facing the first direction X is inwardly recessed to be provided with a flow channel groove 1022, and the spoiler fin 20 is arranged in the flow channel groove 1022. The cover plate 30 is arranged on the heating plate 10 in a lamination manner, the flow channel groove 1022 and the cover plate 30 are sealed to form a flow channel 40 for the refrigerant, and the spoiler fin 20 is located in the flow channel 40.

[0035] Referring to Figure 4 and Figure 5 , the heating plate 10 comprises a first base plate 101 and a second base plate 102 arranged in a lamination manner. The first base plate 101 and the second base plate 102 are fixedly connected by bolts and can be disassembled. The second base plate 102 is arranged on the first direction X side of the first base plate 101. The first base plate 101 is provided with a first pipe groove 1011, and the second base plate 102 is provided with a second pipe groove 1021 corresponding to the first pipe groove 1011. After the first base plate 101 and the second base plate 102 are laminated, the first pipe groove 1011 and the second pipe groove 1021 jointly form a heating channel 103 for mounting the electric heating pipe. When the electric heating pipe is damaged, it can be disassembled and replaced, which is convenient and fast and saves cost. The heating channel 103 is distributed in a serpentine shape along the length direction of the heating plate 10.

[0036] Referring to Figure 3The second substrate 102 is provided with a flow channel groove 1022, which is located at opposite sides of the second substrate 102 respectively with the second pipeline groove 1021. The flow channel groove 1022 extends along the length direction of the heating plate 10 and is distributed in a serpentine shape along the width direction of the heating plate 10. The second substrate 102 is provided with a liquid inlet 1023 for the refrigerant to enter the flow channel groove 1022 and a liquid outlet 1024 for the refrigerant to flow out of the flow channel groove 1022. The liquid inlet 1023 and the liquid outlet 1024 both penetrate the second substrate 102 along the first direction, i.e., along the thickness direction of the second substrate 102.

[0037] The liquid inlet 1023 and the liquid outlet 1024 are arranged at two end portions of the flow channel groove 1022 respectively. The flow channel groove 1022 gradually increases in width from the liquid inlet 1023 to the liquid outlet 1024. The refrigerant enters the heating plate 10 from the liquid inlet 1023, continuously absorbs heat and vaporizes in the process of flowing to the liquid outlet 1024, and in this process, the volume continuously increases, and a larger passage is needed to reduce the resistance in the flow. Therefore, the width of the flow channel groove 1022 needs to be gradually widened to ensure the pressure and flow rate of the refrigerant. The distribution direction of the flow channel groove 1022 is perpendicular to the distribution direction of the heating channel 103, which can make the refrigerant in the flow channel groove 1022 uniformly heated and the heating efficiency higher.

[0038] Referring to Figure 2 and Figure 5 The electric heating evaporator of the embodiment further includes a liquid inlet connector 50 connected with the liquid inlet 1023 and a liquid outlet connector 60 connected with the liquid outlet 1024. The first substrate 101 is provided with a first avoiding opening 1012 and a second avoiding opening 1013 for avoiding the installation of the liquid inlet connector 50 and the liquid outlet connector 60.

[0039] Referring to Figure 6 The turbulence fin 20 includes a plurality of fin units 201, each of which includes a base 2011 and two fin portions 2012 protruding from the base 2011. The two fin portions 2012 are arranged along the length direction of the first substrate 101, and the two fin portions 2012 are arranged in a staggered manner along the width direction of the first substrate 101. Each fin portion 2012 includes a top plate 2012a and first and second side walls 2012b and 2012c located at opposite sides of the top plate 2012a, and the two ends of the first and second side walls 2012b and 2012c are connected with the top plate 2012a and the base respectively.

[0040] The first side walls 2012b of two fin parts 2012 adjacent along the length direction of the first substrate 101 are staggered along the width direction of the first substrate 101, and a first window 2013 is formed between the first side walls 2012b of the two fin parts.

[0041] Working principle: After the electric heating tube is powered on, heat is transmitted to the heating plate 10, and then transmitted to the cover plate 30 and the spoiler fin 20 through the heating plate 10, that is, the entire evaporator is heated, when the evaporator is heated to a set temperature, the refrigerant is input, the refrigerant enters from the liquid inlet 1023, under the disturbance of the spoiler fin 20, fully absorbs heat, and the refrigerant changes from a liquid or gas-liquid two-phase state to a gas state, and is discharged from the liquid outlet 1024.

[0042] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present application without departing from the spirit and scope of the present application. Therefore, it is intended to cover modifications and variations of the present application that fall within the scope of the appended claims and their equivalents.
