Abstract
The utility model relates to a small temperature difference condenser of refrigerating facilities, comprising a condensation tube. The utility model is characterized in that the condensation tube is positioned in a tube with cooling fins. Heat accumulation materials are installed between the condensation tube and the tube with cooling fins. Cooling fins are arranged on the outer surface of the tube with cooling fins. The cooling fins are flat plates or concave and convex plates which are parallel or inclined with the cross-section of the tube with cooling fins, or the cooling fins can also be flat plates or concave and convex plates which are parallel or inclined with the centerline of the tube with cooling fins of the central line of the tube with cooling fins, or the cooling fins can also be snake-shaped or helical convex sheets surrounding the outer surface of the tube with cooling fins. Therefore, the heat dissipation area of the tube with cooling fins is greatly expanded. The heat dissipation area can be expanded to 20 to 40 times the effective area of the condensation tube. Thus, the difference temperature for heat exchange can be effectively reduced. Therefore, a small temperature difference condenser is obtained.
Description
The utility model relates to the condenser in the refrigeration technology field, the little temp-difference condensing device in particularly a kind of small-sized refrigerator that is applicable to discontinuous work such as refrigerator, ice box, cryogenic box, cold drink machine.
At present, be used for the condenser of refrigeration plants such as refrigerator, ice box, four kinds of flat, venetian blind type, threaded pipe type and built-in flat-back types are arranged, its structure all is made up of condenser pipe and radiated rib.Circulation is in order to the cooling substance of refrigeration in the condenser pipe, and the radiated rib that links to each other with condenser pipe plays thermolysis.Condenser pipe placed side by side constitutes plate type condenser on the flat radiated rib; Condenser pipe placed side by side constitutes shutter condenser on the venetian blind type radiated rib; The built-in flat-back type condenser that built-in flat-back type radiated rib and condenser pipe are formed in fact also is a kind of plate type condenser.These condensers only depend on the free convection of air to carry out heat exchange; and because refrigeration plants such as refrigerator, ice box are discontinuous work; its Homes Using TV is generally 40% to 45%; the material of refrigeration machine is steel or copper material; its thermal capacity is very little, when shutting down, and condenser shut down; so its heat transfer temperature difference is big, the entropy of whole refrigeration system increases.
The applicant proposed the patent application of " heat accumulation uninterrupted duty condenser " on February 12nd, 1998 to State Intellectual Property Office, its patent No. is 98100512.8, it is a kind of that this application provides, or at condenser pipe and be equivalent between the shell of radiated rib effect and be full of heat storage material, or in condenser one side and connect the condenser of placing the heat accumulation pipe that is full of heat storage material.This condenser is equipped with heat storage material owing to set up heat accumulation pipe in the heat accumulation pipe, the start of refrigeration plant and shutdown are combined effectively, shunts condensation heat with heat storage material, forms the effect of uninterrupted heat radiation continuously of condenser.But this condenser expansion area of dissipation is limited in one's ability, can not further reduce the temperature difference, and its radiating effect is still not ideal enough.
The utility model purpose is on the basis of above-mentioned " heat accumulation uninterrupted duty condenser ", a kind of little temp-difference condensing device that can further improve radiating efficiency is provided, this condenser has been done further improvement with radiated rib, its area of dissipation is increased significantly, thereby improved the heat exchange efficiency of condenser, further reduced the heat transfer temperature difference of condenser.
Embodiment of the present utility model is as follows:
The little temp-difference condensing device that the utility model provides, comprise condenser pipe, it is characterized in that: condenser pipe is positioned among the radiated rib pipe, heat storage material is housed between the two, have radiated rib on the radiated rib tube outer surface, radiated rib is parallel or favours the flat board or the concave, convex template of radiated rib pipe cross section; Radiated rib also can be parallel or favours the flat board or the concave, convex template of radiated rib tube hub line; Radiated rib also can be around snake type on the radiated rib tube outer surface or screw type lug.
The little temp-difference condensing device that the utility model provides, because condenser pipe is positioned among the radiated rib pipe, heat storage material is housed between the two, have radiated rib on the radiated rib tube-surface again, so the area of dissipation of radiated rib pipe is enlarged significantly, its area of dissipation can expand 20 to 40 times of condenser pipe effective area to, has reduced heat transfer temperature difference effectively, thereby obtains a kind of little temp-difference condensing device.
Further describe the utility model below in conjunction with drawings and Examples:
Accompanying drawing 1,2 is a structural representation of the present utility model,
Accompanying drawing 3,4,5,6,7 is planted structural representation for the youngster who is positioned at the radiated rib on the radiated rib tube outer surface.
Wherein 1 ... condenser pipe 2 ... radiated rib pipe 3 ... heat storage material
4 ... radiated rib
By accompanying drawing 1,2 as can be known, the little temp-difference condensing device that the utility model provides comprises condenser, and feature is: condenser pipe 1 is positioned among the radiated rib pipe 2, and heat storage material 3 is housed between the two, has radiated rib 4 on radiated rib pipe 2 outer surfaces; Radiated rib 4 can be parallel or favours the flat board or the concave, convex template of radiated rib pipe 2 cross sections; Also can be parallel or favour the flat board or the concave, convex template of radiated rib pipe 2 center lines; Also can be around snake type on the radiated rib tube outer surface or screw type lug.Accompanying drawing 3,4,5 just shows and is parallel to several flat radiated rib (also can be the concave, convex template) of (also tiltable in) radiated rib pipe 2 cross sections respectively; Accompanying drawing 6 shows a kind of parallel (also tiltable) flat board (also can be the concave, convex type) formula radiated rib in radiated rib pipe 2 center lines; Radiated rib 4 also can be around snake type on radiated rib pipe 2 outer surfaces or screw type lug, then is a kind of around the screw type lug formula radiated rib on radiated rib pipe 3 outer surfaces shown in the accompanying drawing 4.Radiated rib pipe in the accompanying drawing 1 is a kind of Contiuum type radiated rib pipe, and the radiated rib pipe in the accompanying drawing 2 is a kind of split type radiated rib pipe.
