연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A recirculating bath includes a reservoir for receiving a working liquid, a recirculating pump, and at least one thermal element. The recirculating pump and thermal element are located externally to the reservoir so that the reservoir has an unobstructed working space. The thermal element may be thermally coupled to the working liquid through an interior surface of the reservoir, or the working liquid may be circulated over the thermal element by the recirculating pump in a chamber external to the reservoir. The recirculating bath may also include a lid that provides access to the reservoir by pivoting on a latching hinge. When open, the lid may provide a working surface adjacent to the reservoir. The lid may also include a selector that unlatches the hinge so that the lid can be removed. The recirculating pump may be fluidically coupled to the reservoir via a manifold.

1. A recirculating bath comprising: a reservoir including an interior surface that defines a first space configured to receive a working liquid; a thermal element located externally to the first space and thermally coupled to the working liquid to transfer heat between the working liquid and the thermal element; and a recirculating pump located externally to the first space and fluidically coupled to the first space to circulate the working liquid through the first space, wherein the reservoir includes a partition that defines a primary chamber and a secondary chamber within the first space, the secondary chamber being fluidically coupled to the primary chamber, the primary chamber defining a work area of the reservoir, and the recirculating pump including an inlet and an outlet each fluidically coupled to the primary chamber via the second chamber. 2. The recirculating bath of claim 1, wherein the thermal element is thermally coupled to the working liquid by the interior surface of the reservoir. 3. The recirculating bath of claim 2, wherein the thermal element is an evaporator coil. 4. The recirculating bath of claim 1, further comprising: a thermal chamber external to the reservoir and enclosing at least a portion of the thermal element, the thermal chamber being fluidically coupled to the first space by the recirculating pump so that the working liquid circulated through the first space by the recirculating pump passes through the thermal chamber. 5. The recirculating bath of claim 4, wherein the thermal element is a heating element. 6. The recirculating bath of claim 5, further comprising: a controller operatively coupled to the heating element, the controller selectively activating the heating element so that the working liquid is maintained at a desired temperature. 7. The recirculating bath of claim 1, further comprising: a cooling unit including a compressor and an evaporator, the thermal element comprising at least a portion of the evaporator. 8. The recirculating bath of claim 7, further comprising: a first shell; anda second shell disposed within the first shell to define a second space between the first and second shells, wherein the reservoir comprises the first and second shells, and the at least a portion of the evaporator is located in the second space. 9. The recirculating bath of claim 8, wherein the second shell includes a channel, and the second space is at least partially defined by the channel. 10. The recirculating bath of claim 1, further comprising: a controller operatively coupled to the thermal element and the recirculating pump;a human machine interface operatively coupled to the controller, the human machine interface configured to transmit instructions received from a user to the controller and display information received from the controller to the user; anda housing configured to accommodate the reservoir, the thermal element, the recirculating pump, the controller, and the human machine interface, the housing including a top surface that provides access to the first space that is unobstructed by the thermal element, the recirculating pump, the controller, or the human machine interface. 11. The recirculating bath of claim 1, further comprising: a controller configured to control operation of the recirculating bath; and a level sensor operatively coupled to the controller, the level sensor being located in the secondary chamber and providing a signal indicative of a level of the working liquid to the controller. 12. The recirculating bath of claim 1, further comprising: a lid that provides access to at least a portion of the first space; anda hinge having a latched state that pivotally couples the lid to the recirculating bath and an unlatched state that decouples the lid from the recirculating bath. 13. The recirculating bath of claim 12, further comprising: a keeper coupled to the lid;a post coupled to the recirculating bath; anda selector coupled to the hinge and having a latched position and an unlatched position, the hinge comprising the keeper and the post. 14. The recirculating bath of claim 13, wherein the keeper includes a first guide hole, and the post includes a second guide hole, the recirculating bath further comprising: a linkage coupled to the selector and including an end portion, the end portion being received by the first and second guide holes to couple the keeper to the post in response to the selector being in the latched position, and the end portion being withdrawn from at least one of the first and second guide holes to decouple the keeper and the post in response to the selector being in the unlatched position. 15.
