More than two kinds of heat exchangers, the former is applicable to gas-solid contact heat-exchange system, though the latter is the gas-liquid heat-exchange system, does not meet the requirement of the cooling of vacuum industry stove.The cooling of vacuum industry stove requires system airtight, reaches true sealing.At present, the outer circulation cooling system that is used for cooling industrial vacuum furnace, be that heat exchanger comprises air inlet, air outlet, water inlet, delivery port, cooling water pipe and fin, wherein cooling water pipe and fin all are included in the cavity the inside of heat exchanger fully, hot blast enters in the cavity of heat exchanger by air inlet, by cooling water pipe and fin heat is conducted to cooling water,, increased the volume of heat exchanger because cooling water pipe is included in the cavity fully, cost is higher, and this device is to the requirement height of vacuum pumping pump.
The content of utility model
Technical problem to be solved in the utility model provides a kind of good leak tightness, and volume is little, the outer circulation heat exchanger of the vacuum industry stove that exchange rate is high.
The utility model is a kind of heat exchanger, comprise cavity, air inlet, air outlet, fin, cooling water pipe, total water inlet, total delivery port, fin is enclosed within on the cooling water pipe, and be installed in the cavity of heat exchanger, cooling water pipe interts inside and outside the cavity of heat exchanger, add transition conduit at the position that cooling water pipe contacts with the cavity of heat exchanger, its port is designed to enlarging, and the port of cooling water pipe also is designed to enlarging.The two side that the no-cooling-water pipe passes on the heat exchanger is designed to interlayer, comprises cavity wall and additional wall.The interlayer cooling device is installed on the sidewall interlayer of heat exchanger, is comprised interlayer water inlet tap, interlayer faucet, interlayer water inlet, interlayer delivery port and interlayer communicating pipe.
The utility model has designed a kind of vacuum industry furnace heat exchanger, is applicable to the fast cooling system of outer circulation.The fin of heat exchanger is installed in its cavity, and cooling water pipe interts inside and outside the cavity of heat exchanger, and adds transition conduit at the position of both contacts, guarantee the solderability and the seal of heat exchanger, reduced the volume of whole heat exchanger simultaneously, cost is low, the exchange rate height.

The specific embodiment
The utility model is a kind of heat exchanger, comprise cavity 3, air inlet 1, air outlet 2, fin 7, cooling water pipe 8, total water inlet 11, total delivery port 12, fin 7 is enclosed within on the cooling water pipe 8, and be installed in the cavity 3 of heat exchanger, cooling water pipe 8 interts inside and outside the cavity 3 of heat exchanger, add transition conduit 17 at the position that cooling water pipe 8 contacts with the cavity 3 of heat exchanger, its port is designed to enlarging 18, and the port of cooling water pipe 8 also is designed to enlarging 19.The two side that the no-cooling-water pipe 8 of the cavity 3 of heat exchanger passes is designed to sidewall interlayer 4, comprises cavity wall 5 and additional wall 6.The interlayer cooling device is installed on the sidewall interlayer 4 of heat exchanger, is comprised interlayer water inlet tap 13, interlayer faucet 15, interlayer water inlet 14, interlayer delivery port 16 and interlayer communicating pipe 10.
The air inlet 1 of heat exchanger is installed in the air outlet place of vacuum drying oven, hot blast in the vacuum drying oven enters in the cavity 3 of heat exchanger by the air inlet 1 of heat exchanger, hot blast contacts with cooling water pipe 8 with fin 7, with the heat transferred cooling water, cooling water enters in the cooling water pipe 8 by total water inlet 11, after carrying out exchange heat, discharge by total delivery port 12, cooling water constantly circulates, and heat is drained, and discharge from air outlet 2 hot blast cooling back, effect by blower fan, turn back in the stove, constantly the heat with workpiece exchanges in heat exchanger, until vacuum drying oven and work-piece cools.
Owing to do not carry out in the fast cold operation stage at vacuum drying oven, heat exchanger cavities 3 is in vacuum state, inside and outside differential pressure is big, two sides that cooling water pipe 8 passes on the heat exchanger are because there is the support of pipeline, can bear inside and outside differential pressure, the two side that no-cooling-water pipe 8 passes then is designed to sidewall interlayer 4 structures, promptly adds an additional wall 6 in the outside of the cavity wall 5 of heat exchanger, increases crushing resistance.The interlayer cooling device is installed on sidewall interlayer 4, comprise interlayer water inlet tap 13, interlayer faucet 15, interlayer water inlet 14, interlayer delivery port 16 and interlayer communicating pipe 10, interlayer water inlet tap 13 links to each other with interlayer water inlet 14, and interlayer faucet 15 links to each other with interlayer delivery port 16.The cooling water that enters from total water inlet 11 enters in the sidewall interlayer 4 of a side by interlayer water inlet tap 13 and interlayer water inlet 14, by in the sidewall interlayer 4 that enters into opposite side interlayer communicating pipe 10, successively enter total delivery port 12 and discharge then by interlayer delivery port 16 and interlayer faucet 15.
In the heat exchanger, the transmission form of heat mainly is the heat conduction, therefore fin 7 and circulating water pipe 8 are selected heat transfer coefficient good metal copper, and cavity wall 5 and additional wall 6 are selected stainless steel for use, seal in the cavity 3 of assurance heat exchanger, firm welding is wanted in the contact site between cooling water pipe 8 and the cavity wall 5, therefore adds one section transition conduit 17 in both contacts site, its external port is enlarging 18, can guarantee manufacturability and air-tightness.The port of cooling tube 8 also is designed to enlarging 19, is convenient to and 9 welding of joint bend pipe.
