Description

Technical Field

[0001] The utility model relates to the technical field of cold water plate evaporators, in particular to a cold water plate evaporator with an antifreeze function. Background Art

[0002] An evaporator is a type of heat exchange device with phase change, which is a device that concentrates a solution or precipitates a substance from a solution by heating. An evaporator is mainly composed of two parts: a heating chamber and an evaporation chamber.

[0003] In order to prevent the internal water from freezing, the existing cold water plate evaporator usually drains the water when not in use to achieve the antifreeze effect. However, due to the curved arrangement of the pipes on the evaporator, it is easy to cause water accumulation inside, resulting in partial freezing, increasing the risk of pipe freezing and resulting in low antifreeze effect. In view of this, we propose a cold water plate evaporator with antifreeze function. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet practical needs, and provide a cold water plate evaporator with an antifreeze function to solve the technical problems that the current drainage antifreeze effect is not obvious and there is local freezing.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: to design a cold water plate evaporator with anti-freeze function, including an evaporator and a water inlet pipe on the evaporator, a connecting pipe is detachably installed through the pipe wall of the water inlet pipe, a transfer pipe sleeve is detachably installed on the upper end of the connecting pipe, a hot air blower is detachably installed on the upper end of the transfer pipe sleeve, a support plate is fixedly provided on the inner wall of the connecting pipe, ventilation holes are opened through the plate wall of the support plate, a spring telescopic assembly is detachably installed on the bottom of the support plate, and a sealing plate is fixedly provided at the lower end of the spring telescopic assembly.

[0006] Preferably, the adapter sleeve is funnel-shaped, the diameter of the upper pipe opening of the adapter sleeve is larger than the diameter of the bottom pipe opening, and the pipe wall connecting the upper pipe opening and the bottom pipe opening is inclined.

[0007] Preferably, the diameter of the upper end surface of the spring expansion and contraction assembly is smaller than the diameter of the lower end surface, and the outer wall connecting the upper end and the lower end of the spring expansion and contraction assembly is in the shape of an outer octagonal slope.

[0008] Preferably, the shape of the support plate is the same as the shape of the tube cavity of the connecting tube, and the support plate and the connecting tube are connected by welding.

[0009] Preferably, the outer edge of the blocking plate is in contact and fit connection with the inner wall of the connecting pipe, and the contact surfaces of the blocking plate and the connecting pipe are both smooth surfaces.

[0010] Preferably, a guide block is integrally fixedly provided on the upper side surface of the blocking plate, and the outer wall of the guide block is inclined outward.

[0011] Preferably, a butt joint pipe with the same pipe diameter is fixedly provided on the upper end of the adapter pipe sleeve, and the butt joint pipe is detachably connected to the hot air blower.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can install the hot air blower above the water inlet pipe through the cooperation of the connecting pipe and the adapter sleeve, so that the hot air blown out by the hot air blower can dry the inner wall of the evaporator pipe, thereby avoiding water accumulation and ensuring the dryness of the interior, so as to achieve an effective anti-freeze effect.

[0014] 2. The utility model can compress the flow range of hot air through the cooperation of the large pipe opening and the small pipe opening of the adapter pipe, thereby increasing the flow speed and accelerating the drying speed. The cooperation of the spring telescopic assembly and the sealing plate can conveniently close the connection between the connecting pipe and the water inlet pipe to prevent water from entering the connecting pipe. At the same time, during the blowing process, the wind force can push the sealing plate downward, so that the spring telescopic assembly is extended, thereby releasing the blocking state. The setting of the guide block facilitates the hot air to enter the water inlet pipe, reduces the flow resistance, and improves the effect of the structural setting.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Example: A cold water plate evaporator with antifreeze function, see Figures 1 to 4, including an evaporator 1 and a water inlet pipe 2 on the evaporator 1, a connecting pipe 3 is detachably installed on the pipe wall of the water inlet pipe 2, which can be combined by threaded connection, a transfer pipe sleeve 4 is detachably installed on the upper end of the connecting pipe 3, a hot air blower 5 is detachably installed on the upper end of the transfer pipe sleeve 4, which has the same structure as a hair dryer and can blow out hot air, a support plate 6 is fixedly provided on the inner wall of the connecting pipe 3, a ventilation hole 601 is penetrated on the plate wall of the support plate 6, the shape of the ventilation hole 601 is set as needed to facilitate the passage of hot air, a spring telescopic component 7 is detachably installed on the bottom of the support plate 6, which has the effect of telescopically adjusting the length, and a sealing plate 8 is fixedly provided on the lower end of the spring telescopic component 7, which can close the connecting pipe 3 to prevent water from entering the connecting pipe 3 when the water inlet pipe 2 is filled with water.

[0022] Specifically, the adapter sleeve 4 is in the shape of a funnel, the diameter of the upper pipe opening of the adapter sleeve 4 is larger than the diameter of the bottom pipe opening, and the pipe wall connecting the upper pipe opening and the bottom pipe opening is inclined; by setting the diameter larger at the top and smaller at the bottom, the flow range of the hot air blown out by the hot air blower 5 can be compressed, thereby increasing the wind speed.

[0023] Furthermore, the diameter of the upper end face of the spring expansion component 7 is smaller than the diameter of the lower end face, and the outer wall connecting the upper end and the lower end of the spring expansion component 7 is in an outer octagonal slope shape; such a shape setting can reduce the resistance to the flow of hot air and has a guiding effect.

[0024] Furthermore, the shape of the support plate 6 is the same as the shape of the tube cavity of the connecting tube 3, and the support plate 6 and the connecting tube 3 are welded to each other; the same shape can facilitate welding connection.

[0025] Furthermore, the outer edge of the sealing plate 8 is in contact and fit with the inner wall of the connecting pipe 3, and the contact surfaces of the sealing plate 8 and the connecting pipe 3 are both smooth surfaces; the setting of the smooth surface can improve the tightness of the combination and reduce the connection gap.

[0026] Furthermore, a guide block 801 is integrally fixed on the upper side of the sealing plate 8, and the outer wall of the guide block 801 is inclined outward; the inclined outer wall of the guide block 801 facilitates the flow of hot air, reduces the plane impact force, and facilitates the downward flow of hot air.

[0027] Furthermore, a butt joint pipe 401 with the same diameter is fixedly provided on the upper end of the transfer tube sleeve 4, and the butt joint pipe 401 and the hot air blower 5 are detachably connected; the setting of the butt joint pipe 401 facilitates docking with the hot air blower 5 and increases the range of hot air activity, thereby improving the effect of the connecting tube 3 in compressing the wind speed.

[0028] Working principle: After draining the water in the evaporator 1 pipeline, the valve of the water inlet pipe 2 on the pipeline can be closed, and then the hot air blower 5 can be connected to the power supply to start working, so that the hot air enters the connecting pipe 3 through the adapter sleeve 4. The change in the diameter will compress the wind speed of the hot air, which makes it easy to squeeze the sealing plate 8 in the connecting pipe 3 downward, so that the connecting pipe 3 is connected to the water inlet pipe 2. At the same time, the wind direction can be changed under the action of the guide block 801, which is convenient for the hot air to enter the pipeline of the evaporator 1. Under the action of the hot air, the water droplets remaining on the inner wall of the pipeline can be dried, which can avoid water accumulation inside the pipeline, thereby ensuring the dryness of the inner wall of the pipeline. Through such structural coordination, the anti-freezing effect can be effectively achieved to avoid the problem of pipeline freezing.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
