Abstract
The utility model discloses a heat exchanger, which comprises a core body, wherein the core body includes fins and heat exchange tubes; whirl plates are arranged on the heat exchange tubes; and the core body is placed inside a heat exchanger casing, so as to form heat-conducting medium cavities and heat exchange cavities. The heat exchanger comprises the heat exchange fins; and the heat exchange fins are arranged among the whirl plates. By changing the connection mode of the exchange tubes and tube plates into interference fit connection, the utility model has the advantage that material selecting margin of the heat exchange tubes and the tube plates is increased, and the shock resistance performance at the sealing joints is greatly improved; and as the fins are arranged among the whirl plates to enlarge the radiating area, the land occupation area of the heat exchanger is reduced on the premise of ensuring the heat dissipation; and compared with the prior art, the heat exchange efficiency is higher, and the space usage is smaller.
Description
Technical field
The utility model relates to a kind of heat exchanger, and definite says, is a kind of heat exchanger that is applicable to light duty compressor.
Background technology
Heat exchanger be carry out cold and hot exchange must use equipment, the primary structure of the tubular heat exchanger that traditional compressor is used comprise the tube bank of forming by many heat exchanger tubes and be positioned at the core body formed of tube sheet at tube bank two ends, heat exchanger shell and the deflection plate that is sleeved on the core body formed, the connected mode of heat exchanger tube and end cap generally adopts welding or expanded joint, if but adopt welded seal need select the good material of solderability for use, selection is restricted; Not only workload is big and use the mode of expanded joint, and cost is also higher.Moreover say the machinery that utilizes light duty compressor work generally in office operation, so its floor space should try one's best little.But the little consequence of directly bringing of floor space is that heat exchanger also diminishes thereupon, thereby heat dispersion reduces greatly; And adopt conventional heat exchanger, and its floor space is very big again, has strengthened the floor space of basic machine virtually, and when how can not only reduce mechanical floor space but also guarantee that its heat dispersion does not lose, this is a problem demanding prompt solution.
Summary of the invention
The purpose of this utility model provides a kind of brand-new heat exchanger, is that interference fit increases the selection leeway of heat exchanger tube and tube sheet by the connected mode that changes heat exchanger tube and end cap, and the anti-vibration destructive characteristics of sealing place has simultaneously also had large increase; And, can under the prerequisite that guarantees thermal diffusivity, reduce the floor space of heat exchanger like this, the floor space of also having reduced basic machine simultaneously by fin is set between deflection plate in order to strengthen area of dissipation.
The concrete scheme of the utility model is as follows:
A kind of heat exchanger comprises core body, and described core body is made up of tube sheet, heat exchanger tube, and deflection plate is set on heat exchanger tube, and core body places in the heat exchanger shell, forms heat-conducting medium chamber and heat exchanging chamber, also comprises the heat exchange fin, and described heat exchange fin is arranged between the deflection plate.
As a kind of improvement of the present utility model, comprise that also a heat-conducting medium injects the mouth of pipe, described heat-conducting medium injects the mouth of pipe and places the heat exchanging chamber exit.
As another kind of improvement the of the present utility model, described heat exchanger tube is connected by the interference mode with tube sheet.
As another kind of improvement the of the present utility model, described heat exchanger tube is a straight tube.
As another kind of improvement the of the present utility model, described tube sheet is a metallic stamping pieces.
It is lower that advantage of the present utility model is that it is compared to the prior art cost, and product weight alleviates relatively, and heat exchange efficiency is higher, and it is also littler to take up room.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is a cutaway view of the present utility model.
Fig. 3 is the utility model core body front view.
Member among the figure is: 1-tube sheet, the outlet of 2-heat-conducting medium, 3-heat exchanger shell, the import of 4-heat-conducting medium, 5-deflection plate, 6-fin, 7-heat exchanger tube.
The specific embodiment
Below in conjunction with Figure of description the utility model is described in further detail:
We the utility model discloses a kind of heat exchanger as can be seen by accompanying drawing, it comprises that a heat exchanger tube 7 with some interts the core body that forms into tube sheet 1, core body is provided with deflection plate 5, described core body and deflection plate 5 place in the heat exchanger shell 3, between the outer wall of each root heat exchanger tube and with the heat exchanger shell between formed the heat-conducting medium chamber, and export 2 with heat-conducting medium import 4, heat-conducting medium and be communicated with.The inner chamber of each heat exchanger tube 7 has just formed heat exchanging chamber, and process tube sheet 1 assembles total heat exchanging chamber and is connected with turnover thermal medium mouth (not shown).Described heat exchanger tube adopts straight tube, adopts interference fit between tubesheet holes and the heat exchanger tube, and the anti-shake performance of sealing place improves greatly like this.
The utility model is set to heat-conducting medium import 4 and is in the bottom, heat-conducting medium outlet 2 is in top, in thermal medium import heat exchanging chamber, inject high-temp liquid or gas, simultaneously, to heat-conducting medium import 4 filling heat-conductive media, at this moment, heat-conducting medium will carry out heat exchange through the heat-conducting medium chamber, discharge from heat-conducting medium outlet 2 again, heat-conducting medium in heat exchanger tube with heat exchanging chamber in high-temp liquid, gas carry out sufficient heat exchange, the heat-conducting medium temperature is raise, and high-temp liquid, gas temperature reduce, and reach the purpose of heat exchange.The flow direction that act as the change heat-conducting medium of the deflection plate that is provided with on the core body is so that heat exchange is more abundant.Simultaneously, fin is set also between deflection plate, the purpose that fin is set has been to increase the heat exchange area of heat exchanger tube, the further like this heat exchange efficiency that improved.
