Abstract
A novel heat exchanger structure for the evaporator and heat exchanger of compression air refrigeration driers is composed of a cylinder shell, a rectangle fin tube evaporator core and baffles, wherein the outer surface of the evaporator core is provided with two opposite fixing plates and four sealing plates, an air chamber a is provided between the fixing plates and the evaporator core, an air chamber b is provided between the shell and the fixing plates and between the shell and the sealing plates, the baffles are arranged in the air chamber a to form air convection channels. When in use, air enters into the air inlet to be guided in the air convection channel formed by the baffles to pass the fin tube evaporator core to reach the air outlet, thereby overcoming the low heat efficiency problem caused by over bypass flow in the application of air purification industry, to reduce bypass flow and improve heat exchange efficiency. Under same heat exchange efficiency, the surface area of the evaporator and the shell volume can be reduced by the increase of the heat exchange efficiency, thereby reducing production cost.
Description
Technical field
The utility model belongs to a kind of heat exchanger structure, relates to a kind of new type heat exchanger structure of using the finned tube evaporator core specifically.
Background technology
At present, known compressed air freezing type drier evaporimeter such as Fig. 1, shown in Figure 2, by shell, the finned tube evaporator core, compositions such as segmental baffle, gas is entered by the air inlet on the shell, the air convection channel guiding that forms through deflection plate arrives the gas outlet by the finned tube evaporator core, evaporator shell is a tubular because the finned tube evaporator core is generally rectangle, therefore have greatly gas directly the arcuate gap between expansion core and shell arrive the gas outlet and the finned tube of obstructed pervaporation device wicking surface, the by-pass flow phenomenon that just is commonly called as, this phenomenon occurs and will reduce heat exchanger effectiveness greatly, simultaneously because whole casing directly contacts air-flow in the course of work, so the shell inside and outside differential pressure is bigger, make it cooperate rectangle heat exchanger core if will change the cylindrical outer casing shape this moment, shell must be done thick just can preventing and break, increase production cost.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of new type heat exchanger structure that can effectively reduce by-pass flow, improve the thermal efficiency, reduce cost is provided.
Technical problem of the present utility model is achieved through the following technical solutions:
A kind of new type heat exchanger structure, it includes the cylindrical outer casing of air inlet and gas outlet, be fixed with rectangular fin tubular evaparator core in the shell, reaching is crisscross arranged relatively forms the deflection plate of air convection channel on expansion core, it is characterized in that described rectangle expansion core is provided with two fixed heads outward relatively, other faces are provided with the sealing plate that fixes with this fixed head, between fixed head and expansion core, be reserved with air and deposit chamber a, shell and fixed head, be reserved with the air that connects between shell and the sealing plate and deposit chamber b, between shell and fixed head, also be provided with and connect the pipeline that air inlet and air are deposited chamber a simultaneously; Described deflection plate is crisscross arranged relatively between fixed head and expansion core, and forms air convection channel.
Described deflection plate one end and the fixed head that is crisscross arranged relatively between fixed head and expansion core fixed, and an end is plugged in the expansion core.
Compared with prior art, the utility model is that the outer surface at the rectangle expansion core is provided with relative two fixed heads and four sealing plates, simultaneously between fixed head and expansion core, be reserved with air and deposit chamber a, shell and fixed head, be reserved with the air that connects between shell and the sealing plate and deposit chamber b, deflection plate is arranged on air and deposits formation air convection channel in a of chamber, structure after the improvement is after gas is entered by air inlet, after depositing chamber b by finned tube evaporator core and air, the air convection channel guiding that deflection plate forms arrives the gas outlet, avoid causing the generation of by-pass flow phenomenon, improve the thermal efficiency, two air are deposited and are not had pressure reduction between the chamber in the while course of work, therefore forming air deposits several of chamber a and can do very thinly, because efficient improves the surface area and the enclosure volume that can reduce evaporimeter under the identical situation of heat exchange power, bigger reduces production costs.

The specific embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As Fig. 3, shown in Figure 4, the new type heat exchanger structure, comprise the closed shell 2 that is tubular, outer casing underpart is provided with air inlet 1, top is provided with gas outlet 5, advance, direction difference when the gas outlet also can be according to concrete implement is done regulation, as also being arranged on a left side, right both sides, be fixed with rectangular fin tubular evaparator core 3 in the shell, this expansion core outside is oppositely arranged two fixed heads 8, other faces are provided with this fixed head and fix the sealing plate 7 that constitutes the whole expansion core 3 of encirclement, simultaneously between fixed head and expansion core, be reserved with air and deposit chamber a9, at shell 2 and fixed head, also be reserved with the air that connects between shell and the sealing plate 7 and deposit chamber b10, air is deposited in a of chamber and is provided with, descend in staggered relatively and the formation, the deflection plate 4 of following air convection channel, this deflection plate one end and fixed head are fixed, and an end is plugged in the expansion core.Between shell 2 and fixed head 8, be provided with perforation air inlet 1 and air and deposit the pipeline of chamber a9, when air that air inlet 1 enters after pipeline enters air and deposits chamber a9, the upper and lower expansion core 3 that runs through is to form the waveform convection current under deflection plate 4 effects in air is deposited chamber a, deposit chamber b10 through air then, arrive gas outlet 5 at last, can obtain heat-exchanged air from the gas outlet this moment.
The utility model is applied to the evaporimeter and the heat exchanger of compressed air freezing type drier, the air that enters from air inlet 1 during work could be from the gas outlet after 3 exchanges of finned tube evaporator core 5 be gone out, overcome existing structure in the practical application of air cleaning industry because the excessive problem that influences the thermal efficiency of by-pass flow, can reach and reduce by-pass flow, significantly promote the purpose of heat exchange efficiency, because efficient improves the surface area and the enclosure volume that can reduce evaporimeter under the identical situation of heat exchange power, bigger reduces production costs.
