Abstract
The invention discloses a double-duct air heater and belongs to the technical field of air blower equipment. The air heater comprises a heater body partitioned into an inner heating chamber and an outer heating chamber surrounding the inner heating chamber, the inner heating chamber and the outer heating chamber are provided with air inlets and air outlets, the air inlet of the inner heating chamber and the air outlet of the outer heating chamber are communicated through an air blower, and a heater in the same direction of the ducts is arranged between the inner heating chamber and the outer heating chamber. By the aid of the double-duct air heater, the problems that an existing air heater is large in heat loss and single in function and the multiple air blowing requirements cannot be met can be solved.
Description
Technical field
The present invention relates to Fan Equipment technical field, especially a kind of air-heater with two air channel.
Background technology
Air-heater is widely used a kind of drying equipment, existing a kind of air-heater comprises the air-heater body with heating clamber, this body offers air inlet and air outlet, this air inlet is connected with air blast, in heating clamber, be horizontally arranged with many heaters relative to wind passage.During work, connect blower power supply, air blast is sent into cold air in heating clamber, cold air is from wind passage through heater, and the heat produced after heater energising carries out heat exchange with the cold air passed through, thus the wind-warm syndrome of air outlet is raised, but this air-heater also exists following problem: 1, when air quantity is large or wind speed is too fast, cold air and the exchange heat time short, rate of heat exchange is low, and thermal loss is large; 2, air-heater body only offers the problem that an air outlet can not meet multiple air feed demand.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of two air channels air-heater, and this pair of air channel air-heater can solve existing air-heater thermal loss comparatively greatly, the more single problem that can not meet multiple air feed demand of function.
In order to solve the problem, the technical solution adopted in the present invention is: this pair of air channel air-heater, include air-heater body, be separated into interior heating clamber in air-heater body and go along with sb. to guard him the additional hot cell outside described interior heating clamber, described interior heating clamber and described additional hot cell have air inlet and gas outlet respectively, the air inlet of described interior heating clamber is connected by blower fan with the air inlet in described additional hot cell, is provided with the heater identical with air channel between described interior heating clamber and additional hot cell.
In above-mentioned pair of air channel air-heater technical scheme, technical scheme can also be more specifically: the air inlet of described interior heating clamber and the air inlet in described additional hot cell are all opened in same one end of air-heater body, external heat between the air inlet of described assembling in additional hot cell and the air inlet of interior heating clamber is indoor, and the gas outlet of described interior heating clamber and the gas outlet in described additional hot cell are opened in the other end of air-heater body respectively.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to being separated into interior heating clamber in air-heater body and going along with sb. to guard him the additional hot cell outside interior heating clamber; The heat part of heater externally radiation effectively can be picked up utilization, not only the abundant Appropriate application energy, and meet multiple air feed demand;
2, owing to being provided with the heater identical with wind channel direction between interior heating clamber and additional hot cell; Heater runs through the head and tail of wind passage, and make cold air all can carry out heat exchange through the whole process of wind passage, rate of heat exchange is high.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram of the embodiment of the present invention.
Fig. 2 is that Figure 1A-A is to sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
One shown in Fig. 1, Fig. 2 two air channels air-heater, include air-heater body, be separated into interior heating clamber 2 in air-heater body and go along with sb. to guard him the additional hot cell 1 outside interior heating clamber 2, interior heating clamber 2 has air inlet 2i and gas outlet 2o, additional hot cell 1 has air inlet 1i and gas outlet 1o, the air inlet 2i of interior heating clamber and the air inlet 1i in additional hot cell 1 is all opened in same one end of air-heater body, and the gas outlet 2o of interior the heating clamber 2 and gas outlet 1o in additional hot cell 1 is opened in the other end of air-heater body respectively; The air inlet 2i of interior heating clamber is connected by blower fan 5 with the air inlet 1i in additional hot cell, blower fan 5 is installed in the additional hot cell 1 between the air inlet 1i in additional the hot cell 1 and air inlet 2i of interior heating clamber 2, is provided with around the heater 3 identical with air channel outside interior heating clamber 2 between interior heating clamber 2 and additional hot cell 1.
During work, start blower fan, cold air enters interior heating clamber 2 and additional hot cell 1, two air channel is formed in interior heating clamber 2 and additional hot cell 1, cold air carries out heat exchange in two air channel simultaneously, makes the wind-warm syndrome of respective air outlet raise respectively, wherein, heater runs through the head and tail of wind passage, and the heat part of heater externally radiation is effectively picked up utilization by additional hot cell; The present invention not only makes cold air can carry out heat exchange through the whole process of wind passage, and rate of heat exchange is high, and the abundant Appropriate application energy, and meets multiple air feed demand.
